MRR Growth Rate Calculator
Holding a rate gets harder as the base grows.
Monthly MRR growth
4.9%
doubles every 14.4 months
Sustaining a growth rate gets harder as MRR rises, because the absolute amount required grows with it. Holding 4.9% means adding $2,469 this month and $4,404 in 12 months' time.
How the MRR Growth Rate Calculator works
Sustaining a growth rate gets harder every month, because the absolute amount required grows with the base. Holding 5% means adding £2,500 this month and £4,500 in a year's time — the same percentage, twice the work.

Frequently asked questions
How do I calculate MRR growth rate?
The compound monthly rate: end MRR divided by start MRR, raised to one over the months, minus one. Averaging month-on-month percentages gives a different and less useful figure.
What is a good MRR growth rate?
Early-stage benchmarks of 10% to 20% monthly are widely quoted and rarely sustained beyond a year or two. What matters more is whether the rate is holding or decaying.
What is doubling time?
Log 2 divided by log of one plus the growth rate. At 5% monthly, MRR doubles roughly every fourteen months.
Why does growth naturally decelerate?
Because churn scales with the base and acquisition does not. Holding a percentage growth rate requires acquisition to grow at the same rate indefinitely.
