MRR (Monthly Recurring Revenue) growth with churn shows realistic trajectory. 10% growth with 5% churn nets 5% - half what growth looks like on paper. This calculator projects MRR forward given both rates.
10,000 MRR with 15% monthly growth, 5% churn = 10% net. Over 12 months: 31,400. Over 24: 98,500 - 10x in 2 years. Growth compounds fast in SaaS.
Use to forecast when funding is needed, headcount planning, or hitting specific milestones. Reality check: 5%+ net monthly growth is early-stage; 2-3% is mature SaaS; 1% or less signals product-market fit issues.
A worked example
Try the defaults: current mrr of 10,000, monthly growth rate of 15%, months to project of 12, monthly churn of 5%. The tool returns 31,384.28. You can adjust any input and the result updates as you type — no submit button, no reload. That's the real power here: seeing how sensitive the output is to one or two assumptions.
What moves the number most
The result responds to Current MRR, Monthly Growth Rate, Months to Project, and Monthly Churn. The rate and the time horizon usually dominate — compounding means a small change in either reshapes the final figure more than a similar shift in contribution size. Test this by doubling one input at a time.
The formula behind this
Final MRR = current × (1 + net growth)^months, where net = growth - churn. Everything the calculator does is shown in the formula box below, so you can check the math against your own spreadsheet if you want.
What the score tells you
Headline financial numbers — income, savings, debt — each tell part of the story. This calculation stitches several together into a single read you can track over time. The value is in the direction, not the absolute number.
What this doesn't capture
The score is a composite of the inputs you provide. Life context — job security, family obligations, health, housing — doesn't appear in the math but shapes the real picture. Use the number as a prompt, not a verdict.
£10,000 £ × 15% growth - 5% churn × 12mo = $31,384.28.
