Target ROAS & CPA Calculator

Set an advertising ceiling while preserving a desired profit margin.

Method and assumptions

Break-even is not always a suitable campaign target. This calculator reserves a chosen profit margin before determining how much an order can spend on acquisition.

Maximum ad cost = revenue - non-ad variable costs - desired profit. Target ROAS = revenue / maximum ad cost.

Common questions

How is this different from break-even ROAS?

It reserves a desired profit margin; break-even ROAS allows profit to fall to zero.

Can the target CPA be negative?

A negative result means non-ad costs already exceed revenue after the desired profit reserve.
