Retention Rate: What It Is and How to Calculate Customer Retention

Retention Rate (RR) is the percentage of users who remain customers of a product over a specific period.

Formula:

RR = (Current Customers − Customers Acquired During the Quarter) / Customers at the Beginning of the Quarter × 100%

Why calculate RR:

to evaluate product relevance in the market;

to analyze customer purchasing behavior;

to develop marketing strategies and budgets;

to reduce customer acquisition costs and improve retention of existing users.
