Revenue from better retention +$5,157
Reducing churn from 8% to 4% keeps 24 more members over 12 months. That's $5,157 in revenue you'd otherwise lose — and you didn't have to acquire a single new member to get it.
This isolates the effect of churn on your existing member base with no new members added. In practice, you're also adding new members each month, so your actual member count will be higher. But the revenue difference between churn rates stays the same regardless of growth — better retention always compounds. Industry benchmarks: 3-5% monthly churn is considered top-tier, 5-7% is average, 8%+ signals a retention problem worth addressing.
