Marketing ROI Break-Even Calculator

Find the revenue a campaign must generate simply to cover its cost at your gross margin.

About Marketing ROI Break-Even Calculator

Only the gross margin share of revenue pays for the campaign, so break-even revenue is the cost divided by the margin. The same relationship inverted gives break-even ROAS — at a 60% margin you need 1.67x, not 1x. Teams that target a ROAS of 1 are losing money on every sale; the break-even figure depends entirely on margin and is the only correct floor for a bid strategy.

Formula

Marketing ROI Break-Even

Break-even revenue = campaign cost ÷ gross margin; break-even ROAS = 1 ÷ gross margin

break-even ROAS
Return on ad spend at which the campaign exactly pays for itself
allowable CPA
Gross profit on one order, the most you can pay to win it
