What is MRR Growth Rate?
MRR growth rate is the percentage change in monthly recurring revenue from the start of a month to its end. It's net growth — new business plus expansion, minus contraction and churn — which makes it the honest headline number for a subscription business. Because it compounds, small differences matter enormously: 5% monthly growth roughly doubles revenue in fourteen months, while 10% doubles it in seven.
Why it matters
- It compounds, so it's the metric with the widest gap between how it feels month to month and where it lands after a year.
- As a net figure it can't be gamed by strong sales alone — a great new-business month with heavy churn still shows up as weak growth.
- It's the primary yardstick investors use to judge a subscription business, alongside net revenue retention.
The formula
MRR Growth Rate = ((MRR at End of Month − MRR at Start of Month) ÷ MRR at Start of Month) × 100
- MRR at End of Month
- — monthly recurring revenue on the last day of the month
- MRR at Start of Month
- — monthly recurring revenue on the first day of that same month
How to use this calculator
- 01Take MRR on the first and last day of the same calendar month, both on a normalised monthly basis — divide annual contracts by twelve rather than counting them in full.
- 02Exclude one-off revenue: setup fees, professional services, and usage overages aren't recurring and will make the trend jump around.
- 03Enter both figures to get net month-over-month growth.
- 04Track it as a three-month rolling average. Single months are noisy enough that reacting to one is usually a mistake.
Worked example
A SaaS business started the month at $84,000 MRR. It added $9,200 in new and expansion revenue and lost $1,640 to churn and downgrades, ending at $91,560.
- Starting MRR = $84,000
- Ending MRR = $91,560
- Net change = $91,560 − $84,000 = $7,560
- Growth rate = ($7,560 ÷ $84,000) × 100 = 9.0%
9% monthly compounds to roughly 2.8× over a year — $84,000 becomes about $236,000 MRR if the pace holds. Sustaining that rate as the base grows is the hard part.
Industry benchmarks
Compiled August 2026
Early-stage startup (pre-$1M ARR)
10% – 20% monthly
High percentages are easy off a small base.
Growth-stage SaaS ($1M – $10M ARR)
5% – 10% monthly
Roughly 80–200% annually.
Scaled SaaS ($10M+ ARR)
2% – 5% monthly
Compounding on a large base is a real achievement.
Mature / profitable subscription
1% – 2% monthly
Often a deliberate trade for margin.
Common mistakes
- Including one-time fees and services revenue in MRR, which inflates growth in the months you close them and creates a false decline afterwards.
- Reporting gross new MRR as growth while quietly excluding churn — the resulting number is a sales metric, not a growth rate.
- Multiplying monthly growth by twelve to get an annual figure instead of compounding it.
- Reading a single month as a trend when seasonality, one large deal, or timing of renewals explains most of the movement.
How to improve your MRR Growth
Grow expansion revenue before new logos
Upgrades from existing customers carry near-zero acquisition cost and land immediately, so they move net MRR faster per dollar than new business.
Attack churn — it's growth you already paid for
Every dollar of churn prevented is a dollar of new business you don't have to sell. At scale this is usually the cheapest source of growth available.

Growth that takes eighteen months to pay back its acquisition cost consumes cash faster than it creates it, no matter how good the growth rate looks.

How do I turn monthly MRR growth into an annual rate?+
Compound it: annual growth = (1 + monthly rate)^12 − 1. At 5% monthly that's about 80% annually; at 10% it's about 214%. Multiplying by twelve badly understates the effect.
Should annual contracts count in MRR?+
Yes, normalised — divide the annual contract value by twelve. Counting the full amount in the month it's signed makes MRR spike and then appear to collapse.
What's the difference between MRR growth and net revenue retention?+
MRR growth includes new customers. Net revenue retention looks only at the existing base — expansion minus contraction and churn — so it isolates whether current customers are worth more over time.
Is negative MRR growth always a crisis?+
Not always. Deliberately pruning unprofitable customers, or a price increase that trades volume for margin, can shrink MRR while improving the business. Unexplained negative growth is the problem.
