Product Break-even ROAS Calculator
Use selling price, the non-advertising cost of one order and acquisition cost. See your break-even ROAS, maximum CPA and contribution after ads, including losses.
Start with one typical order: selling price, non-ad order costs and advertising acquisition cost.
Your current business
Change acquisition cost. Compare actual ROAS with the break-even line.
One changed scenario
Read the contribution or loss after advertising. Fixed overhead still needs funding.
A comparison you can investigate
The example is already working. Replace its figures with yours, from the same period.
Compare the advertising ratio with what the order actually leaves behind. A negative contribution stays visible.
Sales revenue required for every rand of advertising; before fixed overhead.
Selling price divided by acquisition cost.
What remains after making and delivering the order, before advertising.
Selling price less order cost and advertising acquisition cost; excludes fixed overhead, financing and tax.
Contribution after advertising divided by selling price.
The comparison uses your inputs and fixed assumptions. It is a planning example, not a prediction.
Pick the problem you recognise. Start with a change you can actually measure.
Break-even CPA = selling price − non-advertising cost per order. Break-even ROAS = selling price ÷ break-even CPA, only when CPA is positive.
Contribution after ads = selling price − order cost − acquisition cost. Negative results remain visible.
Use the same currency and tax basis. Include product, payment, packing, fulfilment, shipping subsidy and other order costs once. This excludes fixed overhead, financing and tax.
