Breakeven ROAS explained: definition, formula, and why it matters

You've probably heard people throw around Return on Ad Spend like it's the whole story. "This campaign hit a 3x ROAS." Fine — but was it profitable? That's what Breakeven ROAS answers.

What is breakeven ROAS?

Breakeven ROAS, or BEROAS, is the minimum ROAS you need to hit to avoid losing money on your ads. It's the line between profit and loss: if your campaign's ROAS is above your breakeven ROAS, you're profitable; if it's below, you're burning cash.

The formula is straightforward:

Breakeven ROAS = 1 / Profit Margin

How do you work through an example?

Say you sell a skincare product for €50. Product cost is €12, shipping and packaging is €5, and transaction and platform fees are €3. That's €20 in total cost, leaving a €30 gross profit. Profit margin is €30 / €50, or 60%.

Breakeven ROAS = 1 / 0.6 = 1.67. Every €1 spent on ads needs to generate €1.67 in sales just to cover costs. Anything below that and you're losing money on that unit.

Why does breakeven ROAS matter more than ROAS alone?

A 3x ROAS can be excellent for one brand and a disaster for another, depending entirely on margin.

Breakeven ROAS gives context to your ROAS. Without it, a reported number is just a number.

How do you calculate your own breakeven ROAS?

You need three inputs: your selling price, your total cost per unit (cost of goods, packaging, shipping, transaction fees), and your profit margin, calculated as (price minus cost) divided by price. Apply the formula: 1 divided by profit margin equals breakeven ROAS.

How do you use it in practice?

Set clear profitability thresholds and label campaigns accordingly: profitable when ROAS exceeds BEROAS, at-risk when they're roughly equal, unprofitable when ROAS falls below BEROAS. That single label tells you where to scale or cut spend.

It also changes how you read creative tests. A new ad hitting 1.5x ROAS sounds weak in isolation, but if your BEROAS is 1.2x, that ad is a keeper. And if your BEROAS runs high — four or five times spend — that's a signal to revisit pricing, reduce costs, or introduce bundles rather than push more budget into the same funnel.

BEROAS only measures first-purchase profitability. A brand with a strong repeat-purchase rate — the same buyers Meta's algorithm needs real purchase signal to identify — can often afford a lower breakeven number, since the true payback includes the second and third order.

What mistakes should you watch for?

Even experienced marketers get this wrong. The common traps: forgetting shipping and packaging costs, ignoring payment or platform fees, leaving out VAT or transaction costs, using an average ROAS instead of product-specific margins, and forgetting that input costs change over time. Keep the number updated every few months — it's not a set-and-forget metric.
