Contribution margin / order–

Your fixed and variable costs exceed the net revenue per order. There is no room for advertising at all — margins or order volume need to change first.

The calculation is a guideline based on your own figures. Fixed costs are spread across your monthly order volume (30 days).

What does break-even ROAS actually mean?

Break-even ROAS is the single most important number when scaling paid media. It tells you where advertising stops being an investment and starts being a loss.

What break-even ROAS is

It's the return on ad spend where your advertising neither earns nor loses money. It's net revenue per order divided by your contribution margin per order — the money left after VAT and every variable cost.

Why it matters

Without it every budget decision is guesswork. With it you know which campaigns to scale, which to cut, and how much you can afford to pay for a new customer across Meta Ads and Google Ads.

Why most calculate it wrong

They use gross revenue including VAT and only subtract COGS. Shipping, transaction fees, packaging, pick & pack and returns are quietly ignored — and the result looks far too comfortable.

When fixed costs belong in the math

Contribution margin doesn't pay salaries, software or agency fees. If advertising should carry the whole business — not just cover itself — include fixed costs. It raises your break-even ROAS, but it's the honest number.
