How the math works
Fees on a sale equal price times the percentage fees, plus the fixed fees, with each part rounded to the cent. If you enter a sales tax rate, card processing is worked out on the price plus tax wherever the platform charges it that way or doesn't say.
Answers below $1.00 are raised to $1.00. That floor is our assumption, not a platform rule.
The lowest price for a target margin starts from (cost plus fixed fees) divided by (1 minus the fee percentage minus the margin), then moves up one cent at a time until the margin still holds after rounding. That is why an answer can sit a cent above the plain formula.
Rounding each fee to the cent is this calculator's rule. Platforms don't publish theirs, so a statement can differ by a cent.
