How to calculate break-even ROAS

Break-even ROAS starts with the contribution left from one order before advertising. That contribution is also the most you can pay to acquire the order without losing money.

Step 1: Max CPA: Max CPA = Selling price − Non-ad costs
Step 2: BEROAS: Break-even ROAS = Selling price ÷ Max CPA

Example

A product sells for 59.99. Product, shipping, payment, and other variable costs total 25.03, leaving a maximum CPA of 34.96. Dividing 59.99 by 34.96 gives a break-even ROAS of 1.72×. A campaign above 1.72× makes money per order; one below it loses money.

Break-even ROAS questions

What is break-even ROAS?

Break-even ROAS is the minimum return on ad spend a campaign must achieve before an order stops losing money. It is based on the revenue left after product and other variable costs, but before advertising cost.

How do you calculate break-even ROAS?

First subtract product cost, shipping, payment fees, and other variable costs from the selling price to get your maximum break-even CPA. Then divide the selling price by that maximum CPA.

Which costs should I include?

Include every cost that changes when you fulfil another order: cost of goods, shipping, packaging, fulfilment, payment processing, per-order app fees, and expected refunds or discounts. Put anything not listed in the other variable cost field.

Is a lower break-even ROAS better?

Usually, yes. A lower break-even ROAS means more contribution margin is available for advertising. It gives a campaign more room to remain profitable as acquisition costs rise.

What happens when my costs exceed the selling price?

There is no viable break-even ROAS because the order loses money before advertising. Raise the selling price or reduce non-advertising costs before spending on acquisition.

What is the difference between ROAS and break-even ROAS?

ROAS describes an actual or planned campaign's revenue divided by ad spend. Break-even ROAS is the profitability threshold for your unit economics. Actual ROAS must be above that threshold to produce profit per order.
