What is MRR? Monthly Recurring Revenue Explained

Every subscription business lives or dies by one number: the revenue it can count on next month. That number is Monthly Recurring Revenue, or MRR. It strips away one-time charges, normalizes annual contracts to a monthly cadence, and gives you a single figure that reflects whether your business is growing, stalling, or contracting. If you run a SaaS product and you are not tracking MRR rigorously, you are flying without instruments.

Understanding what is MRR, and how to break it into its component parts, is the foundation for every other SaaS metric: churn rate, LTV/CAC ratio, quick ratio, and net revenue retention all depend on an accurate MRR figure. This guide covers the formula, the four types of MRR, stage- specific benchmarks, common mistakes, and how to handle edge cases like annual plans and usage-based pricing.

The MRR Formula

At its simplest, MRR is:

MRR = Number of Active Subscribers × Average Revenue Per Account (ARPA)

If you have 400 paying customers at an average of $95/month, your MRR is $38,000. But that headline figure hides critical dynamics. Two companies can both report $38K MRR while one is growing healthily and the other is bleeding customers. The difference only becomes visible when you decompose MRR into its four types.

Four Types of MRR

When people ask what is MRR, the answer is incomplete without covering all four components. Each one tells a different part of your revenue story.

1. New MRR, Revenue from first-time customers acquired during the period. If 25 new customers sign up at an average of $120/month, you added $3,000 in new MRR. This is driven by your sales and marketing engine.

2. Expansion MRR , Additional revenue from existing customers who upgrade plans, add seats, or purchase add-ons. Expansion MRR is the most capital- efficient revenue you can generate because the customer acquisition cost is near zero. Best-in-class SaaS companies generate enough expansion revenue to offset all churn, a state called negative net churn.

3. Contraction MRR , Revenue lost when existing customers downgrade to a cheaper plan or remove seats. A customer moving from $200/month to $80/month represents $120 in contraction MRR. This is the most under-tracked component: many teams lump it in with churn, losing the signal that customers are unhappy but not yet gone.

4. Churned MRR, Revenue lost from customers who cancel entirely. If 8 customers paying an average of $150/month leave, that is $1,200 in churned MRR. Track this with our Churn Rate Calculator to understand the downstream impact.

Your Net New MRR, the figure that reveals true momentum, combines all four:

Net New MRR = New MRR + Expansion MRR − Contraction MRR − Churned MRR

Worked example: Suppose in March your SaaS company recorded $3,000 in new MRR, $1,500 in expansion MRR, $400 in contraction MRR, and $1,200 in churned MRR. Your net new MRR for March is $3,000 + $1,500 − $400 − $1,200 = $2,900. If January MRR was $38,000, your ending MRR for March is $40,900, a 7.6% monthly increase.

MRR Growth Benchmarks by Stage

What counts as "good" MRR growth depends entirely on your stage. According to OpenView SaaS Benchmarks 2025, median and top-quartile figures break down as follows:

Benchmark your own metrics against other SaaS companies with the SaaS Benchmark to see where you sit across MRR growth, churn, LTV:CAC, and gross margin.

Note that growth rates naturally decelerate as the base gets larger , 5% monthly growth on $1M MRR is $50K in new net revenue, which is harder to achieve than 20% on $10K ($2K). Investors understand this and evaluate your growth rate relative to your stage, not against an absolute threshold. For a deeper look at how these metrics fit together, see the complete SaaS metrics guide.

How to Calculate MRR From Mixed Pricing

Most SaaS companies do not have a single pricing model. Handling edge cases incorrectly is a common source of MRR inaccuracy.

Annual plans: Divide the annual contract value by 12. A customer who pays $2,400/year contributes $200/month to MRR. Do not book the full amount in the month of sale, that creates a misleading spike.

Usage-based pricing: Use the contracted monthly minimum as the MRR figure. If a customer commits to $500/month and consistently uses $800, the conservative approach books $500 as MRR and tracks the $300 overage separately. Some companies use a trailing three-month average of actual usage instead, which is acceptable as long as the methodology is consistent.

Freemium: Free users contribute $0 to MRR. Only count them when they convert to a paid plan. Including free users in subscriber counts while computing ARPA artificially deflates your per-account revenue.

Discounted plans: Record MRR at the price the customer actually pays, not the list price. If a customer gets a 25% discount on a $200/month plan, their MRR contribution is $150. Measure growth efficiency using the SaaS Quick Ratio Calculator.

Common MRR Mistakes

1. Counting one-time revenue as recurring. Setup fees, implementation charges, and consulting revenue are not MRR. Including them inflates your figure and creates a false sense of growth. When an investor or acquirer audits your books, one-time revenue mixed into MRR is a red flag that erodes trust.

2. Not normalizing annual contracts. Booking a $12,000 annual deal as $12,000 in January MRR makes January look spectacular and the following eleven months look flat. Spread it to $1,000/month. This is standard practice and required for accurate trend analysis.

3. Lumping contraction into churn. A customer who downgrades from $500/month to $200/month is not the same as a customer who cancels. Contraction signals dissatisfaction that you can still recover from; churn means the customer is gone. Tracking them separately helps you prioritize retention efforts correctly.

4. Ignoring reactivation MRR. When a previously churned customer returns, many teams count that as "new" MRR. Strictly, it should be tracked as reactivation MRR, a fifth category. Miscategorising it inflates your new customer acquisition metrics and masks the fact that your top-of-funnel may be weakening.

MRR vs ARR: When to Use Which

ARR (Annual Recurring Revenue) is simply MRR × 12. They measure the same underlying revenue stream at different time scales, but the context for each matters.

Use MRR when: you need to track month-over-month trends, identify seasonal patterns, measure the impact of a pricing change, or you are below approximately $1M in annualized revenue. MRR is the operating metric, it is what your team should review in weekly and monthly meetings.

Use ARR when: you are communicating with investors, comparing your company to publicly traded SaaS businesses, planning annual budgets, or your annualized revenue exceeds $1M. ARR is the strategic metric, it frames your business at the scale investors think in.

A common mistake is computing ARR by summing the last 12 months of actual revenue. That gives you trailing twelve-month revenue (TTM), not ARR. ARR is a forward-looking projection based on this month's MRR, not a backward-looking sum. The distinction matters when your growth rate is changing. For context on how burn rate interacts with these metrics, see our burn rate guide.

Committed MRR: The Forward-Looking Cousin

Standard MRR is a snapshot of this month. Committed MRR (CMRR), a metric Bessemer Venture Partners popularized for board reporting, adjusts that snapshot for contracts already signed but not yet live and for known future churn that has been formally notified. It answers a sharper question than MRR: given everything we already know is going to happen, what will recurring revenue be a few months out?

The practical recipe is to start with current MRR, add the MRR from signed deals with a future start date, add scheduled expansion such as a contracted seat ramp, then subtract the MRR of customers who have given notice of non-renewal. A company at $40,000 MRR with $6,000 of signed future starts and $2,000 of notified churn is sitting at $44,000 CMRR, a materially different planning number. CMRR is most useful for enterprise-heavy SaaS where long sales cycles mean a large share of near-term revenue is already locked in but not yet recognized in plain MRR.

MRR Is Not Your GAAP Revenue

A trap that surfaces during a first audit or fundraise is treating MRR as if it were accounting revenue. It is not. MRR is a forward-looking operating metric, while recognized revenue under accrual accounting (the ASC 606 standard in the United States) is earned only as the service is delivered. When a customer prepays a $12,000 annual plan, MRR records $1,000 a month, but the accounting books show $12,000 of deferred revenue on the balance sheet that releases to the income statement at $1,000 per month as the subscription is consumed.

ChartMogul and Paddle (which acquired ProfitWell) both stress that the two figures serve different masters: MRR drives growth decisions and investor benchmarking, while recognized revenue drives the financial statements and tax position. SaaS Capital's annual survey of private B2B SaaS companies leans on MRR-based metrics precisely because recognized GAAP revenue lags and obscures the month-over-month momentum operators need to steer by. Keep both, label them clearly, and never present one as the other in a board deck or data room.

Worked Example: Why a Held Growth Rate Compounds So Hard

The benchmarks above are monthly rates, and the trap is reading them as if they were annual. They compound, and the gap between a seed-stage and a growth-stage rate is far wider over a year than the headline numbers suggest. Take the $38,000 MRR base used earlier in this guide and hold it to the seed-stage median of roughly 7.6% month over month, the exact rate the four-types worked example produced when $2,900 of net new MRR landed on top of $38,000. Annualize the starting point first: $38,000 MRR is $456,000 ARR ($38,000 times 12), the figure you would put in front of an investor.

Now compound the 7.6% across twelve months. Month one ends at $40,900, as shown earlier. Month two starts from that higher base, so the same percentage adds more dollars, $3,108 instead of $2,900, and ends near $44,008. Carry that forward and $38,000 grows to roughly $91,523 by month twelve, because $38,000 multiplied by 1.076 to the twelfth power is about 2.41 times the starting figure. That ending MRR annualizes to roughly $1.10 million ARR, so a year of sustained seed-stage growth has taken the business from under half a million in ARR to past the million-dollar mark on recurring revenue alone.

Contrast that with the growth-stage end of the same OpenView SaaS Benchmarks 2025 range. A company already at $1,000,000 MRR growing at the 4% monthly midpoint adds $40,000 in the first month, more raw dollars than the seed company's entire $38,000 base, yet compounds to about $1,601,032 MRR after twelve months, a 60% annual lift rather than the 141% the seed company posted. This is the deceleration the benchmark table encodes: the percentage falls as the base climbs, but the absolute net new MRR keeps rising, which is exactly why investors judge the growth rate against the stage rather than against a fixed threshold.

The discipline the example forces is to separate the rate from the dollars. A founder who sees 7.6% and a founder who sees 4% can be adding very different amounts of recurring revenue, and only the net new MRR figure, the $2,900 versus the $40,000, tells you which engine is actually larger. Normalize annual contracts to monthly, decompose the four types, then read the rate and the dollars side by side; the compounding does the rest.

For SaaS Companies: Why Metric Transparency Converts

SaaS analytics platforms, billing tools, and CFO dashboards are increasingly embedding interactive MRR calculators and benchmark comparisons on their marketing sites. The reasoning is straightforward: a founder who benchmarks their MRR growth against stage-specific data is revealing their revenue, churn rate, and growth trajectory. That is a highly qualified lead, someone who takes data seriously and is likely evaluating paid tooling.

CalcStack customers in the SaaS analytics space report that interactive metric tools convert visitors to signups at roughly 2-3× the rate of static content pages. The mechanism is simple: when someone inputs their own numbers, they engage more deeply and see the tool's value before any sales conversation. If you sell to SaaS founders, offering a free MRR or SaaS metrics dashboard is one of the most efficient top-of-funnel strategies available.
