MRR growth measures how much a SaaS company’s monthly recurring revenue increases or decreases over a defined period. It helps teams understand whether recurring subscription revenue is expanding, how quickly the business is growing, and whether new sales and existing-customer expansion are outweighing cancellations and downgrades.
MRR growth can refer to the absolute change in monthly recurring revenue or the percentage change from one period to another. State which version you are reporting, and keep the calculation consistent so the trend is useful.
How to Calculate MRR Growth
For a simple month-over-month calculation, compare the current month’s MRR with the previous month’s MRR. Use the same definition of recurring revenue in both periods and account for any changes in reporting rules.
MRR growth rate (%) = (Current MRR − Previous MRR) ÷ Previous MRR × 100
Example: If MRR rises from $40,000 in March to $46,000 in April, growth is ($46,000 − $40,000) ÷ $40,000 × 100 = 15%.
The absolute change in this example is $6,000. If the previous period’s MRR is zero, the percentage formula is undefined, so report the absolute change or explain the starting point rather than dividing by zero.
What Drives MRR Growth?
MRR changes through several distinct movements. Separating them makes it easier to identify whether growth comes from acquiring new customers, expanding existing accounts, or reducing revenue losses.
| Movement | Effect on MRR | Example |
|---|---|---|
| New MRR | Increases MRR | A new customer starts a $300 monthly subscription. |
| Expansion MRR | Increases MRR | An existing customer adds seats and pays $100 more per month. |
| Reactivation MRR | Can increase MRR | A former customer resumes a paid subscription, if tracked as a separate category. |
| Contraction MRR | Decreases MRR | A customer downgrades and pays $80 less per month. |
| Churned MRR | Decreases MRR | A customer cancels a $200 monthly subscription. |
Ending MRR = Starting MRR + New MRR + Expansion MRR + Reactivation MRR − Contraction MRR − Churned MRR
Example: Starting MRR is $40,000. New MRR adds $4,000, expansion adds $1,500, reactivation adds $500, contraction removes $1,000, and churn removes $2,000. Ending MRR is $43,000, an absolute increase of $3,000.
Companies may classify reactivation or other changes differently. Define the categories and apply them consistently, and do not count the same revenue movement twice.
MRR Growth vs. ARR Growth
| Metric | Meaning | When it helps |
|---|---|---|
| MRR growth | Change in monthly recurring revenue over a period. | Frequent tracking of subscription revenue momentum. |
| ARR growth | Change in annualized recurring revenue over a period. | Annualized view of the recurring revenue base, especially for planning and reporting. |
| Revenue growth | Change in revenue recognized under accounting rules. | Financial reporting and analysis of revenue earned during a period. |
| Customer growth | Change in the number of customers or accounts. | Understanding whether the customer base is expanding or shrinking. |
These measures can move in different directions. Revenue may grow because existing customers upgrade even when customer count is flat. MRR can also rise while recognized revenue follows a different pattern because billing and accounting rules differ.
Why MRR Growth Matters
- Tracks recurring revenue momentum. Teams can see whether subscription revenue is increasing, flat, or declining.
- Helps assess go-to-market performance. New MRR offers context for sales and marketing results, while expansion MRR can show the impact of customer growth initiatives.
- Reveals retention pressure. Growth can slow when cancellations and downgrades take a larger share of the recurring revenue base.
- Supports planning. Consistent MRR trends can inform budgets and operating plans when considered with costs, cash flow, and other financial measures.
- Improves prioritization. Movement analysis shows which sources of growth or loss deserve further investigation.
How to Improve MRR Growth
- Improve acquisition quality. Focus on customers whose needs match the product and who are likely to reach value and remain subscribed.
- Shorten time to value. Help new customers complete a useful first workflow so they can understand the product’s benefit early.
- Make expansion useful. Offer upgrades, additional seats, or complementary features when they solve a real customer need.
- Reduce avoidable churn. Investigate cancellation reasons, product friction, reliability issues, and poor customer fit.
- Address downgrades. Learn whether customers are reducing spend because of budget pressure, low usage, pricing, or missing functionality.
- Review pricing and packaging. Test whether plans reflect the value customers receive, while keeping changes clear and fair.
- Track each MRR movement. Separate new, expansion, contraction, reactivation, and churned MRR to see what actually drives the net result.
- Analyze customer cohorts. Compare growth and retention by signup period, plan, segment, acquisition source, or use case where data supports it.
- Coordinate teams. Align sales, marketing, product, finance, and customer success on metric definitions and shared goals.
Common MRR Growth Mistakes
- Reporting a percentage without naming the comparison period.
- Using inconsistent MRR definitions from one month to the next.
- Confusing absolute MRR change with percentage growth.
- Counting one-time fees as recurring revenue.
- Ignoring churn and contraction while focusing only on new sales.
- Including new customer revenue in an existing-customer retention metric.
- Comparing growth rates when one period has a zero or unusually small starting value without explaining the limitation.
- Assuming MRR growth alone proves profitability, healthy cash flow, or long-term retention.
Frequently Asked Questions
What is a good MRR growth rate?
There is no single rate that fits every SaaS company. Growth depends on the company’s stage, customer segment, pricing, market, and starting revenue base. Compare performance with your goals and historical trend rather than relying on an unexplained universal benchmark.
Can MRR growth be negative?
Yes. If current MRR is below the previous period’s MRR, the growth rate is negative. This can happen when churn and downgrades exceed new sales, expansion, and reactivation.
Should MRR growth include expansion revenue?
Yes, when measuring the total change in MRR, expansion from existing customers is normally included. For analysis, report expansion separately so it is clear where growth came from.
Is MRR growth the same as new MRR?
No. New MRR comes from customers who begin paying during the period. MRR growth reflects the net change after all included positive and negative recurring revenue movements.
How often should MRR growth be reviewed?
Many SaaS teams review it monthly and use more frequent monitoring when the business needs it. Keep reporting definitions stable and annotate major pricing, billing, or tracking changes.
