FAQ
Why does adding the fee percentage to my price not work?
Because the fee is charged on the higher price too. To net a target you divide by one minus the fee rate rather than multiplying by one plus it — the same gross-up problem as sales tax.
Is payment processing charged on shipping?
On most platforms, yes — the processor takes its percentage of the total the buyer pays, including shipping and sometimes tax. That is the fee sellers most often leave out.
Does free shipping cost less than charging for it?
No, it moves the cost. Free shipping raises conversion on many platforms and the postage still comes out of your margin, so it belongs in the calculation either way.
