Find your payback day.

Enter your day 1, day 7 and day 30 retention. Kadar fits a curve through those three points, integrates it forward to 365 days, and compares cumulative net revenue per install against what you paid for the install. Everything is computed in your browser from your numbers. None of Kadar's fitted parameters are used here.
