MRR Growth Calculator

Projects monthly recurring revenue growth using net growth assumptions.

Enter values to get started.

Compound monthly forecast using net growth after churn. Directional, not divine truth.

What this tool does

This MRR growth calculator projects where monthly recurring revenue could land after a set number of months, using current MRR, expected monthly growth, and monthly churn.

Use it for quick SaaS planning questions:

  • what does current growth imply over the next 6, 12, or 18 months?
  • how much does churn reduce the headline growth rate?
  • does the forecast support hiring, fundraising, or a pricing experiment?

Why it matters

MRR forecasts get dangerous when they only model new revenue. Churn compounds too. A company growing 8% per month and churning 2% per month is not an 8% growth business in practice. It is a 6% net monthly growth business before expansion, contraction, and all the other spreadsheet goblins arrive.

Run conservative, base, and aggressive cases instead of betting the plan on one clean-looking number. For a deeper version of the same forecast, use the SaaS MRR growth calculator. If churn is the open question, compare assumptions with the churn impact calculator.

How to use the result

Treat the output as a planning range, not a board-slide promise. If a small change in churn dramatically changes the result, your next growth lever is probably retention, onboarding, or pricing fit, not another acquisition sprint.

Run this calculator three times with low, expected, and high churn assumptions. Then use the churn impact calculator to see whether reducing churn beats chasing more top-of-funnel growth.

Routing Context

This tool sits inside the broader utility workflow. Use the result as a checkpoint, then compare it with the surrounding guides and calculators before making the next change.

For related next steps, start from the resource library or compare another page in the tool collection. That keeps the utility path connected instead of turning this into a dead-end calculator.
