MRR Growth Rate Calculator
Calculate MRR growth over a period and convert it to CMGR and annualized growth (CAGR).
MRR growth is a fast way to track subscription momentum. For comparisons across different horizons, convert it to CMGR (monthly compounded growth) and annualized growth.

Example
Using the default inputs, the result is:
20%
- Start MRR
- $200,000
- End MRR
- $240,000
- Months between points
- 6
- Target period growth (optional)
- 0%
How to calculate
- Enter start MRR and end MRR for the period.
- Enter the number of months between the two points.
- Review period growth, CMGR, and annualized growth.
Formula
Period growth = (end MRR - start MRR) / start MRR; CMGR = (end/start)^(1/months) - 1; CAGR = (end/start)^(12/months) - 1
- Start and end MRR use the same MRR definition (clean recurring run-rate).
- CMGR assumes smooth compounding; use it for comparison and planning, not as a guarantee.
FAQ
Is MRR growth the same as revenue growth-
Not necessarily. MRR is a recurring run-rate snapshot. Revenue is what you recognize over time and can include non-recurring items.
Should I use CMGR or YoY growth-
Use YoY for seasonal comparisons and external benchmarks. Use CMGR for planning and for comparing scenarios over different horizons.
Common mistakes
- Using start/end MRR from different definitions (one-time items included sometimes).
- Comparing very short windows without seasonality context.
- Mixing run-rate metrics (MRR) with recognized revenue (accounting).
How to interpret
MRR growth tips
- Use consistent snapshots (start/end of the period) and a stable MRR definition.
- Pair with an MRR waterfall to explain what drove growth (new vs expansion vs churn).
- Pair with retention (NRR/GRR) and payback to judge growth quality.
