About Retention Rate

Formula: Retention Rate = ((End Customers - New Customers) ÷ Start Customers) × 100

If you don't track new customers separately, use: Retention Rate = (End Customers ÷ Start Customers) × 100

Why Retention Matters

  • Cost efficiency: Acquiring new customers costs 5-25x more than retaining existing ones
  • Revenue impact: A 5% increase in retention can boost profits by 25-95%
  • Compounding effect: Even small monthly improvements compound significantly over time

Retention vs Churn

Retention and churn are two sides of the same coin: Retention Rate + Churn Rate = 100%

If your monthly retention is 95%, your monthly churn is 5%.
