How the calculation works

Built-in figures are examples, not benchmarks

Break-even CPC = payout × conversion rate × approval rate. Target CPC = break-even CPC ÷ (1 + target ROI).

Reading the result

Choose an illustrative vertical preset or replace every input with campaign data. An optional current bid produces an immediate below, inside or above-ceiling verdict.
