Break-Even ROAS Formula

Break-Even ROAS = 100 / (Gross Margin % - Fees % - Other Costs %)

The denominator is the percentage of revenue left over before ad spend. The smaller that retained share, the higher your required ROAS.

What is break-even ROAS?

Break-even ROAS converts your unit economics into a simple performance target. It tells you the minimum revenue multiple your campaigns need before they stop losing money.

This is especially useful for ecommerce and marketplace businesses where margins, fees, and fulfillment costs vary a lot. It gives media buyers a more realistic target than using revenue alone.

Frequently asked questions

What is break-even ROAS?
Break-even ROAS is the revenue multiple your ads must generate to cover margins, fees, and other variable costs without losing money.
Why can break-even ROAS be higher than 1.0x?
Because you do not keep all revenue. If gross margin is limited and fees or fulfillment costs are meaningful, you need more than one dollar of revenue per ad dollar just to break even.
What costs should I include?
Use gross margin percentage, then subtract marketplace fees, payment processing fees, shipping subsidies, and any other variable costs that scale with each order to get the denominator.
How does break-even ROAS change with higher margins?
Higher gross margins lower your break-even ROAS because a larger share of each revenue dollar remains after product cost. For example, a 60% margin business needs roughly a 1.67x ROAS to break even on ad spend, while a 30% margin business needs 3.3x.
Can I use break-even ROAS for non-ecommerce campaigns?
Yes, though it requires adapting the inputs. For lead generation, estimate the average revenue per lead multiplied by close rate to get an effective conversion value, then apply your margin and cost structure to derive the minimum ROAS needed from the campaign.
