Customer Retention Rate Calculator

Because retention measures whether existing customers stay, and new signups say nothing about that. Include them and a fast-growing store with terrible retention can report a rate above 100%. The classic formula makes the exclusion explicit: (customers at end − new customers acquired) ÷ customers at start. This calculator asks for that already-adjusted retained number directly.

Measured annually, 25–40% of customers making a repeat purchase is typical for general retail, while consumables, pet supplies and beauty often reach 40–60%. Subscription businesses measure monthly, where 90%+ is the goal. High-AOV, low-frequency categories like furniture naturally sit lower — judge yourself against your own purchase cycle, not a subscription benchmark.

Retention sets the "years retained" term in LTV almost directly: average customer lifetime ≈ 1 ÷ churn rate. At 92% quarterly retention (8% churn), expected lifetime is about 12.5 quarters — over three years. Lift retention to 94% and lifetime jumps past four years, raising LTV by a third with zero change to order value or frequency. No other input moves LTV as sharply.

The mechanics with the strongest track record: a genuinely good post-purchase experience (fast shipping, painless returns), lifecycle email and SMS timed to the replenishment cycle, a loyalty program that rewards the second and third order rather than the tenth, and product quality that survives the first use. Retention is mostly product and experience; marketing only reminds.
