How it works

Cohort revenue in this calculator is sum of ARPU × retention^k minus service. With 400 cohort, 28 ARPU USD, 85 retention %, 12 months, 4 service USD the result is $44,845.95 | $11,200.00.

sum = ARPU × (1 − ret^n) / (1 − ret) after the clamp. tot = cohort × sum − cohort × service × months. The formula uses ARPU and retention.
