How to use this calculator
Model user acquisition efficiency from spend, installs, and revenue checkpoints.
How the calculation works
- Enter ad spend and installs.
- Enter total revenue and optional D0/D7/D30 revenue values.
- Review CPI, ROAS, profit/loss, and checkpoint ROAS.
Formula
CPI = ad spend / installs. ROAS = revenue / ad spend x 100.
Example
$10,000 spend, 5,000 installs, and $13,000 revenue means $2 CPI and 130% ROAS.
