What the calculator is doing.

ROAS is entered net revenue divided by ad spend. The contribution remaining is revenue minus variable costs, other allocated costs and ad spend. With no ad spend, the ROAS ratio is unavailable.

The break-even allowance is the amount remaining before ads. Dividing it by orders gives the break-even ad cost per order; dividing revenue by it gives break-even ROAS. If the included non-ad costs use all the revenue, there is no positive ad-spend allowance.

For the target, we also subtract the contribution you want to retain. The remaining allowance divided by orders gives the target ad cost per order. Revenue divided by that allowance gives the target ROAS. Currency inputs use cents, and the retained contribution is rounded to the nearest cent. If the reserve leaves no positive allowance, the target is unavailable.

Target ad allowance = revenue − variable costs − other costs − retained contribution

A sale worth buying.

In the illustrative example, 100 orders generate $10,000 net revenue. Variable costs are $6,500 and other allocated costs are $500. That leaves $3,000 before advertising. Spending $2,000 retains $1,000, or $10 per order.

A 10% retained-contribution target uses $1,000 of the revenue, leaving a $2,000 ad budget allowance: $20 per order and a 5× target ROAS. The break-even boundary is $30 per order and approximately 3.33× ROAS. All figures use AUD and are examples, not client results.

Use the result to ask a better question.

Can your advertising acquire this order mix inside the allowance? What changes when you spend more? Which costs are still missing? If you want to assess new-customer acquisition, separate first-time buyers and include the acquisition costs appropriate to that group.

Allocating a fixed cost across a different number of orders changes the allowance. Revenue attributed by an ad platform can also differ from settled store revenue. Keep the reporting period, attribution basis and costs consistent.

The calculator helps you define the commercial target. Run Ads’ Meta and Facebook advertising management connects that target to the buying argument, campaign response and budget decisions.
