Put in a monthly budget, a target CPA and a 12-month LTV. See the FTDs it buys, the maximum CPA your payback target allows, and the LTV-to-CPA ratio. Everything runs in your browser.
This is a planning tool, not a guarantee. It uses steady-state numbers; real month-one CPA runs higher and compresses along the decline curve. Use it to sanity-check whether a market and budget can hit a payback target before committing spend.
Maximum acceptable CPA equals 12-month LTV multiplied by your payback target. At a 30 percent payback on a 1,657 EUR LTV, the maximum CPA is about 497 EUR.
Frames vary, but many operators aim for at least 3 to 1 over 12 months. The calculator shows the ratio live so you can test a market and budget before committing.
