Churn Rate

Churn rate measures the percentage of customers who leave during a specific period. For subscription e-commerce, the standard formula is: Monthly Churn Rate = (Subscribers Lost During Month / Subscribers at Start of Month) x 100. A 5% monthly churn rate means you lose 5 out of every 100 subscribers each month.

The critical nuance most brands miss: churn should be calculated on the eligible-to-churn cohort, not the total subscriber base. If 1,000 subscribers are mid-cycle and cannot cancel even if they wanted to, including them in the denominator understates your actual churn rate. One subscription brand thought their monthly churn was 10% using the total-base method. When calculated correctly on eligible cohorts, the real retention per cycle was 60-70% — significantly better, but the true problem was in a different area than they expected.

Churn splits into two categories requiring different solutions. Voluntary churn (60-75% of total) happens when customers actively cancel — driven by dissatisfaction, cost, or changing needs. Involuntary churn (25-40%) happens when payments fail — expired cards, insufficient funds, bank declines. Involuntary churn is typically the faster win: implementing smart dunning can reduce payment-related churn by 30-50% within the first month.

Average monthly churn rates for e-commerce subscriptions in 2026: health and wellness 8-12%, beauty and personal care 8-14%, food and beverage 12-18%, subscription boxes 10-15%. Brands with churn below 5% monthly are in the top quartile.

The most important insight about churn: monthly churn compounds. A seemingly modest 5% monthly churn compounds to 46% annual churn — nearly half your subscriber base turns over each year. This is why small churn improvements have outsized impact on LTV and business value.
