Your minimum
The formula
Minimum total = (fixed fee + postage + packaging + target profit) ÷ (1 - referral rate), rounded to the cent, then raised to your floor if you set one.
Why divide? The referral fee is a percentage of the price itself, so every dollar you add to the price also adds to the fee. Dividing by (1 - rate) solves for the price where what's left after the percentage fee covers everything else. Repricers that set a minimum on the total (item + shipping) can use this number directly; if yours sets the item price only, subtract the shipping you charge.
