How Payment Fees Affect Your Margin

Account for card and transaction fees when modelling product profitability.

Fees scale with sales

Percentage transaction fees rise with the selling price, while fixed per-transaction fees affect small orders disproportionately.

Include them consistently

Decide whether fees belong in variable cost when comparing products and channels.

Compare channels

A channel with higher fees can still be worthwhile if it generates more demand or reduces other costs.
