Work out the total transaction fee on a payment and its effective percentage of the sale.
Fees stack: a percentage commission, a percentage payment-processing charge and a flat per-transaction fee. Because the flat fee is constant, the effective fee rate is much higher on low-value orders than on high-value ones. On a low-value order the fixed fee alone can exceed the margin, which is why payment sellers need a minimum order value rather than a flat margin target.
