Churn Rate Calculator — Customer & Revenue Churn Metrics

What is this? Churn rate is the percentage of customers or revenue you lose in a given period. A 5% monthly churn rate means you lose 5% of your customers every month — meaning your entire customer base turns over in 20 months without new signups.

Why it matters: Reducing churn by just 1% can double the value of your business. It's the most leverageable metric in SaaS.

Industry benchmarks: B2B SaaS: 3-5% monthly churn (good) / 7%+ (concerning). B2C: 5-7% monthly. Enterprise: <1% monthly.
