Monthly Recurring Revenue (MRR) is the metric most subscription businesses use to answer one question: how much predictable revenue is this business generating right now, normalized to a monthly amount? If you run a SaaS product, sell memberships, or bill customers on a recurring basis, MRR is usually the first number you look at each month. It's also one of the most misunderstood metrics in startup finance, because founders often confuse it with cash collected, total revenue, or contract value. This guide walks through what MRR actually means, how to calculate it correctly, the different components that make it move, and how it compares to ARR, revenue, bookings, and cash flow.
What Is Monthly Recurring Revenue (MRR)?
Quick Definition
Monthly Recurring Revenue (MRR) is the total amount of predictable, recurring subscription revenue a business expects to receive in a given month, normalized across all active subscriptions regardless of their original billing frequency.
SaaS and subscription companies use MRR because it converts subscriptions billed weekly, monthly, quarterly, or annually into one comparable monthly figure. That makes it possible to track growth, spot churn, and compare performance month over month on a consistent basis. Payment platforms like Stripe describe MRR as one of the most important forward-looking metrics a subscription business can track.
It's worth being precise here: MRR is a business and operating metric, not a formally defined accounting figure. It is not the same as GAAP-recognized revenue, and it isn't governed by a specific accounting standard the way recognized revenue is under frameworks like ASC 606, the U.S. revenue recognition standard. Companies commonly build their own internal policies for what counts toward MRR, which is why the same underlying subscription base can sometimes produce slightly different MRR figures across different tools or teams if the calculation rules aren't documented consistently.
MRR Meaning in Simple Words
The easiest way to understand MRR is to picture a snapshot of every paying customer's monthly-equivalent subscription value, added together.
Hypothetical example
A SaaS company has:
- 80 customers paying $50/month
- 20 customers paying $100/month
Monthly recurring revenue:
80 × $50 = $4,000
20 × $100 = $2,000
Total MRR = $6,000
Notice that only the recurring subscription amount is counted. If those same 100 customers each paid a one-time $200 onboarding or setup fee when they signed up, that fee would not be added to MRR. Setup fees, one-time consulting charges, and other non-recurring payments don't represent revenue the business can reliably expect again next month, so including them would overstate how predictable the business actually is.
Why MRR Matters for SaaS Companies
MRR is popular because it condenses a lot of operational reality into one trackable number. Founders use it to understand:
- How much predictable recurring revenue the business currently has
- Whether the business is growing, flat, or shrinking month to month
- How much revenue is being lost to churn
- How much revenue existing customers are adding through upgrades
- Broad revenue trends that inform sales and marketing decisions
- Whether the sales or product-led motion is producing consistent results
- Financial planning inputs, including hiring pace and budget decisions
- Cash planning alongside actual collections data
- What to report to investors and board members
SaaS Insight
MRR tells you how much recurring revenue exists — it doesn't by itself tell you whether that revenue is healthy, efficient to acquire, or likely to stick around. A rising MRR number next to rising churn and shrinking margins is not necessarily a business in good shape. MRR should always be read alongside retention, margin, and cash metrics, not in isolation.
MRR Formula
MRR = Number of Customers × Average Monthly Recurring Revenue per Customer
This simplified formula works well when every customer pays roughly the same amount, or when you just need a quick, rough estimate of recurring revenue. In practice, most SaaS companies have multiple pricing tiers, discounts, add-ons, and mixed billing cycles, so the average-based formula becomes less precise as pricing complexity grows.
The more accurate and widely used approach is to calculate the monthly-normalized recurring value of every individual active subscription, then sum them:
MRR = Sum of the monthly-normalized recurring value of all active subscriptions
How to Calculate MRR Step by Step
Step 1: Identify Active Subscriptions
Start with every subscription currently generating recurring revenue. Trials, canceled subscriptions, and subscriptions with failed payments are typically excluded, since there's no active recurring commitment behind them.
Step 2: Determine Monthly Recurring Value
For each subscription, identify the amount the customer is billed and the billing frequency (monthly, quarterly, annual, and so on).
Step 3: Normalize Longer Billing Periods
Convert non-monthly subscriptions into a monthly-equivalent value. An annual plan is divided by 12; a quarterly plan is divided by 3.
Step 4: Exclude Non-Recurring Charges
Remove one-time setup fees, one-time professional services, hardware charges, and any other non-recurring line items from the calculation.
Step 5: Add All Recurring Monthly Amounts
Sum the normalized monthly value across every active subscription to arrive at total MRR.
Illustrative example
A small SaaS company has three active subscriptions:
- Customer A: $40/month (monthly plan)
- Customer B: $480/year (annual plan) → $480 ÷ 12 = $40/month
- Customer C: $150/quarter (quarterly plan) → $150 ÷ 3 = $50/month
Total MRR = $40 + $40 + $50 = $130
How Annual Subscriptions Affect MRR
This is one of the most common sources of confusion for new founders. When a customer pays $1,200 upfront for an annual subscription, the business does not generate $1,200 of MRR in that month.
Hypothetical example
Annual subscription: $1,200/year
Normalized MRR: $1,200 ÷ 12 = $100 MRR
The $1,200 represents cash collected and contracted billings, but only $100 counts toward MRR in that month, and that same $100 continues to count each subsequent month the subscription remains active. This distinction matters because billing, cash collected, MRR, and recognized revenue are four different things:
- Billing — what the customer was invoiced
- Cash collected — what actually hit the bank account, and when
- MRR — the normalized monthly value of the recurring commitment
- Recognized revenue — the amount formally recorded as earned under the company's accounting policy, typically spread over the service period
Treating a large upfront annual payment as a single month of MRR would badly overstate that month's recurring revenue and understate every following month, which is exactly the kind of mistake that misleads founders and investors. Stripe's own billing documentation confirms this normalization approach — an annual subscription for $1,200 counts only $100 toward MRR.
What Should Be Included in MRR?
| Usually Included | Usually Excluded |
|---|---|
| Recurring monthly subscription fees | One-time setup fees |
| Normalized annual or quarterly subscriptions | Implementation fees |
| Recurring add-ons | One-time consulting or professional services |
| Recurring plan upgrades | Hardware sales |
| Recurring seat or usage-based charges tied to an ongoing subscription | Non-recurring professional services |
| — | Refunds, handled per the company's documented metric policy |
The exact list can vary slightly by company, especially around usage-based pricing and discounts. What matters most is that the methodology is documented and applied consistently, so MRR trends actually reflect changes in the business rather than changes in how the metric is calculated.
The Different Types of MRR
Total MRR is useful, but it hides where growth (or loss) is actually coming from. Breaking MRR into components gives founders a much clearer picture of what's driving the number. SaaS analytics platforms such as ChartMogul classify these as MRR movements, tracking each subscription change as New Business, Expansion, Contraction, Churn, or Reactivation.
New MRR
Recurring revenue generated from customers who signed up during the period and were not previously paying customers.
Expansion MRR
Additional recurring revenue from existing customers, through upgrades, additional seats, add-ons, or higher recurring usage.
Reactivation MRR
Recurring revenue from customers who previously churned and later returned as paying customers.
Contraction MRR
Recurring revenue lost when existing customers downgrade or reduce their recurring usage, without fully canceling.
Churned MRR
Recurring revenue lost when customers cancel their subscription entirely.
Net New MRR
The combined effect of every MRR component above — the net change in total MRR for the period once gains and losses are accounted for.
Net New MRR Formula
Net New MRR = New MRR + Expansion MRR + Reactivation MRR − Churned MRR − Contraction MRR
Terminology and exact implementation can vary slightly between SaaS analytics tools and billing platforms, so it's worth documenting how your business defines each category — for example, how a downgrade that doesn't cancel a subscription is classified versus a full cancellation.
Worked example
New MRR = $8,000
Expansion MRR = $3,000
Reactivation MRR = $500
Churned MRR = $2,000
Contraction MRR = $500
Net New MRR = $8,000 + $3,000 + $500 − $2,000 − $500 = $9,000
Complete MRR Calculation Example
All figures below are a hypothetical SaaS business used purely for illustration.
Hypothetical pricing
- Starter: $29/month
- Pro: $79/month
- Business: $199/month
Hypothetical Month 1 customer counts
- 150 Starter customers → 150 × $29 = $4,350
- 60 Pro customers → 60 × $79 = $4,740
- 15 Business customers → 15 × $199 = $2,985
Month 1 Total MRR = $4,350 + $4,740 + $2,985 = $12,075
Now suppose, in Month 2, the following hypothetical events occur:
- 20 new Starter customers sign up → New MRR = 20 × $29 = $580
- 5 Starter customers upgrade to Pro → Expansion MRR = 5 × ($79 − $29) = $250
- 2 Pro customers downgrade to Starter → Contraction MRR = 2 × ($79 − $29) = $100
- 8 Starter customers cancel → Churned MRR = 8 × $29 = $232
Net New MRR = $580 + $250 − $100 − $232 = $498
Month 2 Total MRR = $12,075 + $498 = $12,573
Even though total MRR only grew by $498, the breakdown shows real gains from new business and expansion that were partly offset by contraction and churn — information a single top-line number would completely hide.
MRR Growth Rate
MRR Growth Rate = ((Current MRR − Previous MRR) ÷ Previous MRR) × 100
Hypothetical example
Previous MRR: $50,000
Current MRR: $55,000
Growth Rate = (($55,000 − $50,000) ÷ $50,000) × 100 = 10%
A 10% month-over-month growth rate means recurring revenue grew by one-tenth compared with the prior month. Whether that rate is strong or weak depends heavily on company stage, starting MRR size, and how sustainable the growth sources are — new customers, expansion, or a mix of both.
What Is a Good MRR?
There is no universal "good" MRR figure. A company with $10,000 in MRR and a company with $1,000,000 in MRR can both be performing well — or poorly — relative to their own stage, market, and cost structure. Comparing raw MRR across companies without context is rarely useful.
Instead of chasing a benchmark number, MRR is best interpreted alongside:
- MRR growth rate
- Gross margin
- Churn rate
- Customer concentration (how dependent MRR is on a small number of accounts)
- Customer Acquisition Cost (CAC)
- Customer Lifetime Value (LTV)
- Burn rate
- Startup runway
- Net and gross revenue retention
A founder trying to judge business health from MRR alone, without this surrounding context, is only seeing part of the picture.
MRR vs ARR
| Attribute | MRR | ARR |
|---|---|---|
| Full name | Monthly Recurring Revenue | Annual Recurring Revenue |
| Time period | One month | One year |
| Calculation | Sum of monthly-normalized recurring revenue | MRR × 12, or the annualized value of recurring contracts |
| Best suited for | Short-term, month-to-month tracking | Long-term planning and reporting |
| Sensitivity to short-term changes | High — reacts quickly to churn, upgrades, new sales | Lower — smooths short-term fluctuations |
| Typical use | Operational tracking, sales performance, early-stage growth signals | Investor updates, annual budgeting, valuation conversations |
| Example | $10,000 MRR | $120,000 ARR |
The simplified relationship is:
ARR ≈ MRR × 12
This relationship is most useful when recurring revenue is relatively stable and a company applies consistent definitions of MRR and ARR. In practice, reporting conventions can vary between companies, so it's worth checking how a specific business defines each metric before comparing figures directly. For a deeper breakdown of annualized recurring revenue, see Annual Recurring Revenue (ARR).
MRR vs Revenue
| Concept | What it represents |
|---|---|
| MRR | Normalized monthly value of active recurring subscriptions |
| Revenue (recognized) | Amount formally recorded as earned under the company's accounting policy, often spread over a service period |
| Cash collected | Actual money received in the bank during the period |
| Bookings | Total contracted value of deals signed during the period, regardless of billing or recognition timing |
Consider a hypothetical customer who signs an annual contract for $2,400, paid upfront. That single event produces four different numbers: a $2,400 booking, $2,400 of cash collected in that month, $200 of MRR ($2,400 ÷ 12), and recognized revenue that is typically spread across the 12-month service period rather than recorded all at once. None of these four figures are interchangeable, and treating any two of them as identical is a common source of confusion for early-stage founders.
MRR vs Bookings
Bookings generally represent the total contracted value of an agreement — what a customer has committed to, regardless of how or when it's billed. MRR, by contrast, represents the normalized recurring monthly value of active subscriptions.
Simple example
A customer signs a 2-year contract worth $24,000 total. That's a $24,000 booking. If billed and recognized evenly, the recurring monthly value contributing to MRR would be $24,000 ÷ 24 months = $1,000 MRR.
MRR vs Cash Flow
A SaaS company can collect a full year of subscription payment upfront while its MRR remains a normalized monthly figure. Paddle's SaaS finance guidance makes a similar point: MRR and ARR behave more like bookings than like accounting revenue, since they reflect committed recurring spend rather than cash timing. This is exactly why MRR should never be used as a substitute for cash-flow analysis. A business could show healthy, growing MRR while still facing a cash crunch if too much revenue is tied up in deferred annual contracts, if collections are slow, or if expenses outpace collected cash. MRR measures recurring revenue momentum; it does not measure how much cash is actually available to run the business.
MRR vs ARPU
ARPU (Average Revenue Per User, sometimes called ARPA — Average Revenue Per Account) is closely tied to MRR through a simple relationship:
MRR = Number of Customers × ARPU
If MRR grows because ARPU is rising, that typically signals successful upsells, better pricing, or a shift toward higher-value customers. If MRR grows mainly because customer count is rising while ARPU stays flat or falls, growth is coming primarily from volume rather than expansion. Tracking both figures together helps explain what's actually driving MRR movement.
How Churn Affects MRR
Every canceled subscription directly reduces MRR by the amount of recurring revenue that customer represented.
Hypothetical example
Starting MRR: $100,000
Churned MRR: $5,000
MRR after churn, before accounting for any new or expansion MRR: $100,000 − $5,000 = $95,000
This is why churn is tracked separately from total MRR — a business can be adding new customers every month and still see total MRR stagnate or shrink if churn is high enough to offset those gains. As ChartMogul explains in its revenue churn benchmarks, this is exactly why net and gross revenue churn are tracked as separate metrics from total MRR.
How Expansion Revenue Increases MRR
Expansion MRR comes from existing customers spending more over time, through:
- Plan upgrades
- Additional seats or user licenses
- Recurring add-ons or feature packages
- Increased recurring usage on usage-based pricing
- Cross-selling additional recurring products
Expansion revenue can become an important growth driver because it comes from a customer base that has already been acquired. That said, expansion isn't automatically cheaper or easier than acquiring new customers — it still requires product investment, customer success effort, and a pricing structure that gives customers a natural reason to grow their spend.
MRR and Customer Acquisition Cost
Comparing MRR growth against acquisition spend gives founders a rough sense of whether growth is being purchased efficiently. If Customer Acquisition Cost (CAC) is rising faster than New MRR, the business may be spending inefficiently to generate each new dollar of recurring revenue. That said, MRR growth alone doesn't tell you whether CAC is efficient — it needs to be evaluated together with CAC payback period, gross margin, and retention, not from MRR figures in isolation.
MRR and Customer Lifetime Value
Customer Lifetime Value (LTV) depends heavily on how long customers stick around and how much they spend while they do, both of which are reflected in a company's MRR components. Strong Expansion MRR and low Churned MRR generally support higher LTV, since customers are both staying longer and spending more over time. Because LTV calculations typically build on retention and recurring revenue assumptions, accurate MRR tracking is a foundational input for reliable LTV estimates.
MRR and Product-Market Fit
Rising MRR is an encouraging signal, but MRR growth by itself does not prove Product-Market Fit (PMF). A company could grow MRR through aggressive sales or heavy discounting while retention, engagement, and organic demand remain weak underneath the surface. Genuine product-market fit is usually reflected across multiple signals together — retention holding steady or improving, customers engaging with the product without heavy intervention, organic or referral-driven growth, and expansion revenue building naturally, alongside manageable churn. MRR growth is one useful data point among several, not proof on its own.
Common MRR Calculation Mistakes
Warning: These mistakes commonly distort MRR reporting
Counting One-Time Revenue
Including setup fees, onboarding charges, or one-time services inflates MRR with revenue that won't repeat.
Counting Full Annual Payments in One Month
Recording an entire annual payment as that month's MRR instead of dividing it by 12 dramatically overstates a single month's recurring revenue.
Including Non-Recurring Services
Consulting engagements, custom development, or hardware sales shouldn't be folded into recurring subscription revenue.
Ignoring Downgrades
Failing to track Contraction MRR hides revenue erosion happening within the existing customer base.
Ignoring Churn
Reporting only gross new MRR without netting out cancellations overstates real growth.
Double Counting Expansion
Recording the same upgrade in both New MRR and Expansion MRR — or counting it every month instead of only in the month it occurred — inflates growth figures.
Mixing Different Currency Policies
Combining subscriptions in different currencies without a consistent conversion policy produces unreliable totals, especially as exchange rates shift.
Changing the Calculation Method Without Documentation
Switching how MRR is calculated between months — even for good reasons — without documenting the change makes historical comparisons misleading.
Confusing MRR With Accounting Revenue
Treating MRR as equivalent to recognized revenue on financial statements conflates a management metric with a formally defined accounting concept.
Consistent, documented methodology matters more than any single formula. A business that applies the same rules every month produces a trustworthy trend line, even if its exact definitions differ slightly from another company's.
How SaaS Companies Can Grow MRR
- Acquire qualified customers — focus on segments likely to retain and expand, not just sign up
- Improve activation — help new customers reach value quickly, which supports retention
- Reduce churn — identify at-risk accounts early and address the reasons customers leave
- Improve onboarding — a smoother first experience reduces early cancellations
- Increase retention — consistent product value keeps existing MRR intact
- Create appropriate upgrade paths — give customers a natural reason to move to higher tiers
- Expand accounts — grow seats, usage, or add-ons within the existing customer base
- Improve pricing and packaging — align plans with the value customers actually receive
- Re-engage churned customers — win-back campaigns can generate Reactivation MRR
- Strengthen product-market fit — sustainable MRR growth tends to follow genuine product value, not the other way around
Founder Tip
Raising prices can lift MRR in the short term, but it doesn't automatically improve long-term recurring revenue. If a price increase pushes churn higher or slows new customer acquisition, the net effect on MRR growth can be negative. Treat pricing changes as something to test and monitor, not a guaranteed lever.

MRR Example for an Early-Stage SaaS Startup
The scenario below is entirely hypothetical and is used only to illustrate how MRR components combine into a monthly total.
| Month | Total MRR | Main drivers |
|---|---|---|
| Month 1 | $2,000 | Initial customer base |
| Month 2 | $3,200 | New MRR $1,400; Churned MRR −$200 (net change +$1,200) |
| Month 3 | $4,500 | New MRR $1,000; Expansion MRR $400; Churned MRR −$100 (net change +$1,300) |
| Month 4 | $5,600 | New MRR $900; Expansion MRR $400; Churned MRR −$200 (net change +$1,100) |
Total MRR is climbing steadily in this hypothetical example, which looks encouraging on the surface. But a careful founder would dig deeper into the breakdown rather than simply celebrating the top-line number: is churn creeping up relative to the size of the customer base? Is New MRR slowing down even as Expansion MRR picks up the slack? Is growth increasingly dependent on a small number of large accounts? The components behind the total are usually more informative than the total itself.
Can MRR Be Negative?
Total MRR itself represents the recurring revenue a business currently has, so it isn't typically described as a negative number in the ordinary sense — it's either zero or a positive value reflecting active subscriptions.
Net New MRR, however, can absolutely be negative. This happens when Churned MRR and Contraction MRR combined exceed New MRR, Expansion MRR, and Reactivation MRR combined for a given period.
Hypothetical example
New MRR = $2,000
Expansion MRR = $500
Reactivation MRR = $0
Churned MRR = $3,000
Contraction MRR = $200
Net New MRR = $2,000 + $500 + $0 − $3,000 − $200 = −$700
A negative Net New MRR month means total MRR shrank compared with the prior period — a signal worth investigating immediately rather than waiting for the trend to continue.
Is MRR Only for SaaS Companies?
No. While MRR is most closely associated with SaaS, it's useful for any business with genuinely recurring revenue, including membership businesses, subscription apps, subscription media services, and recurring service plans. The metric is most meaningful where revenue is truly recurring and reasonably predictable — businesses with mostly one-off or highly irregular purchases won't get much value from tracking MRR.

Frequently Asked Questions About MRR
What does MRR stand for?
MRR stands for Monthly Recurring Revenue.
What is MRR in SaaS?
In SaaS, MRR is the normalized monthly value of all active subscription revenue, used to track predictable recurring income and growth trends.
How do you calculate MRR?
Sum the monthly-normalized recurring value of every active subscription, excluding one-time charges. Annual and quarterly subscriptions are divided by 12 or 3 respectively to get a monthly value.
What is the MRR formula?
The simplified formula is MRR = Number of Customers × Average Monthly Recurring Revenue per Customer. The more precise approach sums the normalized monthly value of each individual active subscription.
What is New MRR?
New MRR is the recurring revenue generated from newly acquired customers during a given period.
What is Expansion MRR?
Expansion MRR is additional recurring revenue from existing customers, generated through upgrades, extra seats, add-ons, or increased usage.
What is Churned MRR?
Churned MRR is the recurring revenue lost when customers cancel their subscriptions.
What is Net New MRR?
Net New MRR is the combined net change in MRR for a period: New MRR + Expansion MRR + Reactivation MRR minus Churned MRR and Contraction MRR.
What is the difference between MRR and ARR?
MRR measures recurring revenue on a monthly basis, while ARR measures it on an annualized basis. ARR is generally approximated as MRR × 12.
Is MRR the same as revenue?
No. MRR is a normalized recurring-revenue metric, while recognized revenue is an accounting concept that follows specific recognition rules and can differ from MRR, cash collected, or contract bookings.
Are annual subscriptions included in MRR?
Yes, but they're normalized. An annual subscription's value is divided by 12 and that monthly-equivalent amount is what counts toward MRR.
Should one-time fees be included in MRR?
Generally no. Setup fees, onboarding charges, and other one-time payments aren't recurring, so including them overstates predictable revenue.
What is a good MRR?
There is no universal benchmark. What counts as "good" depends on company stage, growth rate, margins, churn, and overall financial context rather than the raw MRR figure alone.
Can Net New MRR be negative?
Yes. Net New MRR turns negative when Churned MRR and Contraction MRR together exceed New MRR, Expansion MRR, and Reactivation MRR combined for that period.
Is MRR a GAAP metric?
No. MRR is a business/management metric commonly used in subscription businesses. It is not a formally defined GAAP accounting measure and should not be treated as equivalent to recognized revenue on financial statements.
Key Takeaways
- MRR is the normalized monthly value of all active recurring subscription revenue.
- The basic formula is MRR = Number of Customers × Average Monthly Recurring Revenue per Customer, though summing normalized individual subscriptions is more precise.
- Annual and quarterly subscriptions must be normalized to a monthly value — never counted in full in a single month.
- MRR breaks down into New, Expansion, Reactivation, Contraction, and Churned MRR.
- Net New MRR combines those components into the true net change for the period, and can be negative.
- MRR and ARR are related (ARR ≈ MRR × 12) but serve different planning purposes.
- MRR is not the same as recognized revenue, cash collected, or bookings.
- Consistent, documented calculation methodology matters more than chasing a specific formula.
Final Thoughts
MRR earns its place as a core SaaS metric not because it produces a single clean number, but because its components reveal where recurring growth is actually coming from — and where it's quietly leaking out. A founder who only checks the top-line MRR figure each month is missing most of the story. Tracking New, Expansion, Churned, and Contraction MRR alongside the total gives a far more accurate read on business health. From here, it's worth exploring related metrics like ARR, churn rate, CAC, and LTV to build a fuller picture of how the business is really performing.
Editorial Note: This article was researched using reliable SaaS measurement resources and authoritative financial/accounting guidance where relevant. MRR is a business metric, not a standardized accounting figure, and businesses may define individual components differently — readers should rely on their own accounting records and a qualified accounting professional for formal financial reporting.
