SaaS Churn Rate Calculator

How to calculate Logo Churn vs Revenue Churn calculator?

Logo churn measures the share of customers lost, while revenue churn measures the share of recurring revenue lost; both give complementary views of customer and revenue health.

Key formulas: Logo Churn = (Customers Lost / Starting Customers) × 100
Revenue Churn = (MRR Lost / Starting MRR) × 100

Using the Logo Churn vs Revenue Churn calculator calculator: an example

Example values: Starting Customers = 1,000; Customers Lost = 50; Starting MRR = $100,000; MRR Lost = $5,000; Expansions = $3,000.

Step-by-step calculation:

1. Calculate logo churn: 50 / 1,000 = 0.05 → 5% logo churn.
2. Calculate gross revenue churn: $5,000 / $100,000 = 0.05 → 5% gross revenue churn.
3. Account for expansions to get net revenue churn: ($5,000 − $3,000) / $100,000 = 0.02 → 2% net revenue churn.
4. Compare results: identical logo and gross revenue churn suggests lost customers had proportional ARR; lower net churn indicates expansion offsets.

Frequently Asked Questions

Which churn metric should I prioritize?

Prioritize the metric that aligns with your goal: logo churn for customer retention initiatives, revenue churn for financial impact and pricing/expansion strategies.

Can revenue churn be lower than logo churn?

Yes. If lost customers were lower-value but expansions or upsells from remaining customers offset some lost revenue, revenue churn can be lower than logo churn.

How often should I measure churn?

Measure churn monthly to detect trends quickly, but analyze quarterly and annually for strategic planning and smoothing seasonality.
