Calculate the commission a marketplace charges and the proceeds left to the seller.
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 marketplace sellers need a minimum order value rather than a flat margin target.
