Break-even ROAS calculator

Find the revenue per advertising dollar needed to cover the costs you enter. A threshold, not a demand forecast or a profit guarantee.

Save one set of costs and campaign inputs on this browser only. It includes your amounts; avoid saving on a shared device. Saving replaces the previous set. Results are recalculated when you submit, and saved inputs do not sync to other devices.

Calculate a valid estimate to save its inputs.

Use whole orders from the same month and the average order value above. Leave blank for a threshold only. Use one attribution source to avoid counting the same order twice.

Optional: leave blank or use 0 for cost-only break-even. A positive target reserves that share of order revenue after entered costs and ads. This is an entered-cost target, not net profit; omitted costs still apply.

Enter all four values. Order value must exceed product cost after fees. Payment fee must be below 100%.

Enter your costs, then calculate your threshold.

Contribution per order = order value × (1 − payment fee %) − product cost. Break-even ROAS = order value ÷ contribution. For a target margin after ads, subtract order value × target margin % from the contribution available for ads first. The target is based only on entered costs. The threshold depends on costs even when ad spend is zero.

Revenue assumes continuous sales; whole orders round up to cover spend. Include relevant variable costs in product cost. Excludes refunds, tax, overhead and any costs you leave out. A custom percentage excludes fixed fees unless you include their equivalent. Imported PayPal/Etsy mode includes the fixed fees listed on its source calculator.
