What Is Break-Even ROAS?

ROAS tells you how much attributed revenue advertising produced. It does not tell you whether the orders were profitable. Break-even ROAS, often shortened to BEROAS or BE ROAS, adds product economics to the decision.

At the break-even point, revenue covers product cost, order-level fees, fulfillment, shipping, and advertising. There is no profit left, but there is no modeled loss either. This makes BEROAS a threshold rather than a growth goal.

What goes into break-even ROAS?

Start with average order value or selling price. Then subtract costs that move with each order:

• Product cost or COGS
• Shipping paid by the seller
• Fulfillment, pick-and-pack, or agent fees
• Percentage and fixed payment processing fees
• Platform or marketplace fees tied to the sale
• Other defensible per-order variable costs

The amount left is contribution margin before advertising. It is also the maximum break-even CPA for one average order.

A worked BEROAS example

Suppose an ecommerce order produces $50 in revenue. Product cost is $15, shipping is $5, and fees plus other order costs are $3. Total non-ad variable costs are $23, leaving a $27 contribution margin.

Divide $50 by $27. Break-even ROAS is 1.85x and break-even CPA is $27. A campaign at 2.20x ROAS spends about $22.73 to acquire that order, leaving roughly $4.27 before overhead and other excluded costs.

BE ROAS vs ordinary ROAS

Ordinary ROAS is an observed campaign metric: attributed revenue divided by ad spend. BEROAS is a calculated threshold: order revenue divided by contribution margin. The campaign becomes profitable under this model only when observed ROAS is higher than BEROAS.

A 2x result is therefore neither automatically good nor bad. If break-even ROAS is 1.6x, a 2x campaign has room for profit. If BEROAS is 2.4x, that same campaign loses money.

Break-even ROAS vs target ROAS

Break-even allocates the entire contribution margin to advertising. Target ROAS reserves part of the margin as profit. If a store has a 50% contribution margin, BEROAS is 2x. If the store wants a 20% profit margin, only 30% of revenue is available for ads, so target ROAS rises to about 3.33x.

Use the target ROAS calculator after you know contribution margin. The distinction prevents a break-even result from being treated as a healthy profit goal.

When the result needs more context

The basic calculation does not automatically include returns, taxes, chargebacks, overhead, cash-flow timing, or customer lifetime value. Add a reliable per-order allowance when appropriate, and do not assume repeat purchases unless your own data supports them.

Recalculate when price, discounts, supplier cost, shipping, product mix, or payment fees move. A store does not have one permanent BEROAS when its unit economics change.
