CPA vs RevShare Calculator
CPA pays once, now. RevShare pays a little every month, indefinitely. So there is a month where the share overtakes the fee. Find it, compare it against how long your players actually stay, and the decision makes itself.
Which model pays more
Stay longer than this and the revenue share is ahead. Shorter, and the flat fee is.
What the break-even does not tell you
The arithmetic assumes you can wait. If you buy media, the revenue share’s upside arrives months after the invoice for the traffic, and a campaign that is correct on paper can still be one you cannot fund.
It also assumes you know your retention, which on a new casino you do not. The first months are the measurement. And it assumes no negative carryover: where losses roll forward, the real break-even can be pushed out indefinitely.
