Break-even POAS and the margin bands behind it

Break-even POAS is always 100% on gross profit — but the ROAS you need to get there depends entirely on your margin band. Here is how to find yours.

Profit Bid connects store costs to ad spend so you bid on margin — not vanity ROAS.

% ROAS to break even

Break-even POAS is always 100%, but thin-margin bands need a much higher ROAS to reach it.

Why break-even POAS is a constant

Unlike break-even ROAS, break-even POAS does not change with margin: it is always 100%, because it compares profit to spend directly.

What changes is the ROAS required to reach 100% POAS. A 20% margin band needs far more revenue per ad dollar than a 50% band.

Margin bands and their ROAS floors

Segment your catalog into margin bands. For each, the break-even ROAS is 1 ÷ margin — and the profit target should sit comfortably above it.

Bidding on profit lets you enforce these bands automatically instead of managing a spreadsheet of per-category ROAS targets.

Step-by-step

Follow these in order — each step builds on the previous one.

  1. 1

    Group SKUs by margin band

    Split the catalog into low/mid/high margin buckets (e.g. 20/35/50%).

  2. 2

    Compute each band's ROAS floor

    Break-even ROAS = 1 ÷ margin for the band.

  3. 3

    Add a profit buffer

    Set the live target above break-even to cover fixed costs and profit.

Frequently asked questions

Common questions about this topic — tap to read answers.

Is break-even POAS the same for every store?

Yes — it is always 100%. What differs is the revenue efficiency (ROAS) each store needs to reach it, based on margin.

What buffer should I add above break-even?

Enough to cover fixed costs and desired profit — often a target of 120–200% POAS depending on overhead and LTV.
