Mrr Growth With Churn
Calculator

Gross growth is new and expansion MRR added in a period, ignored churn entirely. Net MRR growth, which this calculator projects, subtracts churned and downgraded MRR from that gross figure, so it reflects what actually happens to your recurring revenue balance month over month.

Churn compounds against your growth just like interest compounds for you: at a constant new-MRR addition and a fixed churn percentage, MRR converges toward an equilibrium level rather than growing forever, because losses scale with the base while additions stay flat. A 3% monthly churn rate against flat new sales will plateau your MRR, not just slow its growth.

Use revenue churn (dollars lost) rather than logo churn (customers lost), since MRR growth is a dollar figure and a calculator using customer-count churn will misstate the dollar impact whenever customers of different sizes churn. If your smallest customers churn most, logo churn overstates revenue damage; if your biggest accounts churn, it understates it.

Enter new-customer MRR and expansion MRR as separate additions if the calculator supports it, since they behave differently: expansion revenue usually has a much lower churn rate than new logos in their first year. Lumping them together with a single blended growth number hides that expansion is often your most durable growth lever.

That flattening (an asymptote) happens when your churn rate and new-MRR addition rate reach a steady-state balance, meaning the MRR you're losing each month roughly equals the MRR you're adding. To keep growing past that point, you need to either add more new MRR per month, reduce the churn rate, or grow expansion revenue faster than churn.
