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).
