How to calculate revenue growth
Revenue growth compares current revenue against a prior period, or forecasts future revenue by compounding a monthly growth rate. This calculator models where revenue could land after multiple months of consistent growth.
- • Use net revenue, not vanity gross volume, for serious planning.
- • Compare monthly growth and annualized run-rate.
- • Model conservative, base, and aggressive cases before making hiring or ad spend decisions.
Why compounding matters
A small monthly growth rate can become meaningful over a year. But compounding also works in reverse: churn, seasonality, and retention issues can flatten growth faster than a simple spreadsheet suggests.
Revenue growth feels intuitive until you try to model compounding. A 10% MoM growth rate compounds to 213% annually — but few businesses actually sustain that. This calculator models realistic compounding with seasonality and decay.
What each input means
Get these inputs right and the output is reliable. Get them wrong and the calculator just multiplies bad assumptions.
Current monthly revenue
Most recent full month's revenue.
Typical range: Any starting point.
Growth rate
Expected month-over-month growth %.
Typical range: 5–15% MoM is realistic for early-stage; 2–5% at scale.
Time horizon
Number of months to project.
Typical range: 12 for annual planning; 36 for fundraising.
Worked examples
Real scenarios with the math walked through line by line.
Early-stage SaaS
Scenario: $10k MRR, 12% MoM growth, 12 months.
Math: Month 12 = $10k × 1.12^12 = $38,960.
Outcome: ARR run-rate $467k. Realistic if cohort churn stays controlled.
Common mistakes
Where this calculation usually goes wrong in the real world.
- Assuming constant growth. Real growth decays as you scale.
When to use this calculator
- Annual planning.
- Fundraising deck projections.
Glossary
MoM growth
Month-over-month percentage growth.
T2D3
Triple, triple, double, double, double — the SaaS gold standard.
More questions answered
What's a realistic growth rate to use?
Use your trailing 3-month average, not your best month. Apply a decay factor of 0.95–0.98 per month at scale to model the natural slowdown.

FAQ
What is the revenue growth formula?
Growth rate = (current revenue - previous revenue) divided by previous revenue. Forecast revenue can be modeled as starting revenue multiplied by (1 + growth rate) for each period.
What is good monthly revenue growth?
It depends on company stage. Early projects may grow fast from a small base, while mature businesses often prioritize steady, profitable growth.
Should I use MRR or total revenue?
For subscription businesses, MRR is usually best. For content, ecommerce, or ads, use the revenue metric you actually manage month to month.
