Mobile Game Session Length & Retention Calculator

Calculate average session length, retention rates (Day 1, Day 7, Day 30), churn rate, and lifetime value indicators for mobile games.

Total Sessions in Period Total Playtime (minutes) Average Sessions per Active User per Day

Day 0 (Install) Users Day 1 Returning Users Day 7 Returning Users Day 30 Returning Users

Daily Active Users (DAU) Monthly Active Users (MAU) ARPDAU — Avg Revenue per DAU ($)

Average Session Length = Total Playtime (min) ÷ Total Sessions

Daily Playtime per User = Avg Session Length × Sessions per Active User per Day

Day N Retention Rate = (Users Active on Day N ÷ Day 0 Install Users) × 100

Day 1 Churn Rate = (Day 0 Users − Day 1 Users) ÷ Day 0 Users × 100

DAU/MAU Stickiness = (Daily Active Users ÷ Monthly Active Users) × 100

Monthly Revenue Estimate = ARPDAU × DAU × 30

Daily Churn Rate = 1 − (DAU ÷ MAU)^1/30

Player LTV = ARPDAU ÷ Daily Churn Rate
