SaaS Churn Rate Calculator

Calculate your customer (Logo) and revenue churn rates. Understand the health of your subscription business and project the long-term impact of attrition.

The Silent Killer of SaaS Growth

Churn is the single most important metric for the long-term viability of a subscription business. You can have the best marketing in the world, but if your Churn Rate is too high, you are filling a leaky bucket.

This SaaS Churn Calculator helps you distinguish between Logo Churn (customers lost) and Revenue Churn (dollars lost). You can track these specific expansion and contraction movements in detail with our MRR Calculator.

Logo Churn

The % of customer counts lost. High logo churn usually indicates product-market fit issues or poor onboarding for smaller accounts.

Gross Revenue Churn

The % of revenue lost strictly due to cancellations and downgrades. This represents the total "bleeding" of the business.

Net Revenue Churn

The gold standard. It factors in upsells (Expansion MRR). If Expansion > Cancellations, you have Negative Churn (Growth).

Churn Formulas

Net Revenue Churn

((Lost MRR - Expansion MRR) ÷ Start MRR) × 100

Measures financial health. Can be negative (which is good!).
