Game Retention Calculator

Convert a new-player cohort and D1, D7 and D30 retention percentages into retained-player counts. The same percentage can mean very different operational outcomes at different acquisition volumes.

Retention percentage is not enough

Read retention together with cohort size, acquisition source, platform, territory and build version. Following how a D1 player survives to D7 and D30 is more useful for separating onboarding, content pacing and economy problems.

A practical measurement rule

When evaluating a patch or onboarding change, compare similar acquisition cohorts over comparable dates. Collapsing mixed user groups into a single percentage can produce the wrong product decision.
