See Profit on Ad Spend vs revenue-only reporting
Profit Bid connects store costs to ad spend so you bid on margin — not vanity Return on Ad Spend.

Why break-even Profit on Ad Spend is a constant
Unlike break-even Return on Ad Spend, break-even Profit on Ad Spend does not change with margin: it is always 100%, because it compares profit to spend directly.
What changes is the Return on Ad Spend required to reach 100% Profit on Ad Spend. A 20% margin band needs far more revenue per ad dollar than a 50% band.
Margin bands and their Return on Ad Spend floors
Segment your catalog into margin bands. For each, the break-even Return on Ad Spend 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 Return on Ad Spend targets.
