Calculator guide

Separate customer churn from revenue churn

Customer churn measures the share of starting customers lost during a period. Revenue churn measures recurring revenue lost, while net revenue churn also reflects contraction and expansion among retained customers.

Enter only customers and MRR present at the beginning of the period. New customers acquired during the period should not inflate the starting denominator. Use the same period for all movement values.

Net revenue churn can be negative when expansion revenue exceeds churned and contracted revenue. That does not mean customer churn is zero; customer count and revenue retention answer different questions.

Analyze churn by product, plan, cohort, acquisition channel and customer segment. A blended average can conceal a high-risk cohort or the impact of a small number of large accounts.

Formula

Separate customer churn from revenue churn

Customer churn = Lost customers ÷ Starting customers × 100; Net revenue churn = (Churned MRR + Contraction − Expansion) ÷ Starting MRR × 100

Set the opening customer and MRR populations.
Measure customers and recurring revenue lost.
Add contraction and subtract expansion for net revenue churn.
Compare customer and revenue churn separately.

Worked example

Inputs

Scenario: 20 lost customers from 1,000 equals 2% customer churn. With $2,000 churned MRR, $500 contraction and $1,500 expansion on $100,000 starting MRR, net revenue churn is 1%.

Results

Result: 20 lost customers from 1,000 equals 2% customer churn. With $2,000 churned MRR, $500 contraction and $1,500 expansion on $100,000 starting MRR, net revenue churn is 1%.

Frequently asked questions

Churn Rate Calculator FAQ

What should I verify before using this metric?

Verify the time period, population, currency, attribution and revenue or cost definition. Save those assumptions with the report so future comparisons use the same scope.

How accurate is the result?

The arithmetic follows the displayed formula. Accuracy depends on using complete inputs from the same reporting period and applying one consistent definition to customers, revenue and costs.

Can I use another currency?

Yes. Keep every monetary input in the same currency. Ratios and percentages remain comparable, but the calculator does not perform foreign-exchange conversion.

Should I use gross or net revenue?

Use the revenue definition that matches your reporting purpose and keep it consistent across periods. Document whether discounts, refunds, credits and taxes are included.

Why should I compare several periods?

A single month can be distorted by seasonality, annual renewals, campaigns or one-off contracts. Compare a consistent monthly or quarterly series before making a decision.

Is this an accounting standard?

No. It is an independent planning tool. Reconcile the result with your billing platform, analytics system and financial reporting policies.

Are my inputs uploaded?

No. Calculations run locally in the browser and do not require sending calculator inputs to a server.
