MRR Growth Calculator: When Will You Hit $10K MRR?
See exactly when you will reach $10K MRR (or any goal) at your current growth rate, the growth rate you need to hit a target by a deadline, and your compounded monthly growth rate (CMGR).
| Milestone | Time | Date |
|---|---|---|
| $5K MRR | 10 months | |
| $10K MRR | 17 months | |
| $25K MRR | 2.3 years | |
| $50K MRR | 2.8 years | |
| $100K MRR | 3.4 years | |
| $250K MRR | 4.3 years | |
| $500K MRR | 4.8 years |
How MRR growth compounds
MRR growth is usually measured as a monthly percentage, and it compounds. A product at $1,000 MRR growing 10% a month doesn't reach $2,200 in a year. It reaches $3,138, because each month's growth is on a bigger base.
MRR after n months = current MRR × (1 + monthly growth rate)ⁿ
How long until I reach my goal?
Rearranging the formula gives the number of months to any target:
Months to target = ln(target ÷ current) ÷ ln(1 + growth rate)
From $2,000 MRR growing 8% a month, $10,000 MRR is ln(5) ÷ ln(1.08) ≈ 21 months away. At 15% a month it's only 11.5 months. Small changes in growth rate move the date a lot, which is why founders track growth obsessively.
What growth rate do I need?
If you have a deadline, like "$10K MRR before my savings run out in 18 months", work backwards:
Required monthly growth = (target ÷ current)^(1 ÷ months) − 1
Use the second tab of the calculator to find it.
Compounded monthly growth rate (CMGR)
Real growth is bumpy: +30% one month, +2% the next. CMGR turns a messy history into one comparable number:
CMGR = (ending MRR ÷ starting MRR)^(1 ÷ months between) − 1
Going from $1,500 to $6,000 MRR over 12 months is a CMGR of 12.2%. Use CMGR rather than an average of monthly percentages, which overstates growth when months are volatile.
What's a good MRR growth rate?
There's no single answer, but common reference points:
| Stage | Strong monthly growth |
|---|---|
| Under $10K MRR | 10–20% (small base, big swings) |
| $10K–$100K MRR | 7–15% |
| $100K MRR+ | 5–10% |
Y Combinator famously suggests 5–7% weekly growth during the program for very early companies. For a bootstrapped indie product, steady 5–10% monthly growth is excellent and compounds into a real business within a few years.
Why projections are optimistic
Growth rates almost always decay as a product gets bigger. Your first 100 customers come from your network and launches, and the next 1,000 need repeatable channels. Treat any projection more than 12 months out as a motivating scenario, not a plan. Also note that this projection uses net growth. If churn rises as you grow, net growth falls even when new sales stay flat.
When you hit a milestone, make a card and share it. See the guide to building in public for why that helps you grow.
Frequently asked questions
How long will it take to reach $10K MRR?
Months to target = ln(10,000 ÷ current MRR) ÷ ln(1 + monthly growth rate). From $1,000 MRR at 10% monthly growth it takes about 24 months, and at 20% about 12.6 months.
What is CMGR?
Compounded monthly growth rate: (ending MRR ÷ starting MRR)^(1 ÷ number of months) − 1. It is the constant monthly rate that would take you from the start value to the end value.
What is a good monthly MRR growth rate?
For early-stage SaaS under $10K MRR, 10–20% monthly is strong. Between $10K and $100K MRR, 7–15% is strong. Growth naturally slows as the base gets larger.
Does this calculator include churn?
Use your net growth rate, meaning growth after churn. If you know gross new growth and churn separately, subtract churn from growth to get the net rate.
