ROAS Calculator

Enter ad spend, revenue and an optional profit margin to see ROAS, the break-even point and profit.

ROAS divides revenue by spend; it does not separate tax, labour or organic sales.

Reading the result

ROAS is the ratio of revenue from ads to ad spend. 4.00x means every 1 unit spent returns 4 units in revenue. When you enter a margin, the tool calculates break-even ROAS; if 4.00x sits below that point, the campaign may generate revenue without covering the margin. The profit line subtracts spend from revenue after margin.

ROAS and profitability

ROAS and profit are not the same

4.00x looks strong, but a thin margin can still leave no profit. The try-the-example button loads 12,000 spend, 48,000 revenue and a 45% margin: ROAS 4.00x, break-even 2.22x, profit 9,600. At the same revenue with a 20% margin, break-even would be 5.00x and the campaign would lose 2,400. ROAS alone is not enough to decide.

How break-even ROAS is calculated

Break-even ROAS = 1 / gross margin. At a 45% margin, 1 / 0.45 = 2.22x, the minimum return needed to cover ad spend. The margin should be gross margin after product cost; fixed costs, tax and labour stay outside this threshold. A higher margin lowers the break-even point.

Which revenue should I include?

Enter only revenue attributed to ads, and remove returns, VAT and shipping consistently. Platform-reported ROAS can differ from a blended figure that covers every channel. Do not compare two campaigns without using the same date range and currency.

Remaining questions

Should ROAS be read as a ratio or a percentage?

Both describe the same value: 4.00x = 400%. The ratio answers “how much revenue per unit spent” directly, so it is less confusing when comparing campaigns. The percentage is only a presentation difference.

Should a campaign be stopped when ROAS is below 1?

Not automatically. If direct revenue does not cover spend, the campaign runs at a short-term loss; new customer acquisition, repeat purchases and contributions to other channels can change the picture. Check lifetime value and attributed conversions before deciding.

Should organic sales be added to ROAS?

Not for ad ROAS; only revenue from ads belongs in the calculation. If you want to see organic and paid revenue together, calculate a separate blended return rate and do not mix the two metrics in one chart.

Next step

After reviewing the return, tag the campaign link with the UTM builder and check the landing page title.

Method, sources and author

The formulas are ROAS = revenue / spend, break-even ROAS = 1 / gross margin and profit = revenue × margin − spend. The example values were checked against the tool's output on 4 November 2026; they are illustrative numbers, not a real campaign result. Tax and fixed costs are not included.
