About the Repeat Purchase Rate Calculator

Repeat purchase rate is the cheapest growth metric in e-commerce: the share of customers who came back and bought again. Because the second sale carries no acquisition cost, a few points of movement here is usually worth more than the same effort spent on new traffic.

Enter how many customers bought more than once and your total customer count for the period, and the rate appears straight away, with the number of one-time buyers sitting alongside it. Add your average order value and the calculator shows what a five-point improvement would be worth in extra orders and revenue.
