How this calculator works
The answer does not change between Quick and Detailed. This is the professional finance underneath it — the formula, assumptions and mechanics you can inspect when you want the extra detail.
Floor price
Floor price = (cost + fixed per-sale fees) ÷ (1 − target margin % − variable fee %). The lowest you can sell for and still land at the target margin on every sale.
Use it as a sanity guard
Pin it as a "don’t go below this" line — combine with the target selling price from the related pricing ladder to set the headline retail around the top of the band.
