ControlFee, the profit-first pricing calculator
A calculator for ecommerce sellers that works backward from a desired net profit to a selling price after costs, shipping, marketplace fees, and fulfillment.
Field notes
ControlFee asks sellers to begin with a target net profit, then combines product cost, shipping, marketplace fees, fulfillment, and other expenses to derive a selling price. Its visible example starts with a $15 profit target and listed costs of $19.35, producing a $34.35 price. The site describes calculations for Amazon, Walmart, Etsy, eBay, and a seller’s own store, with access offered as a one-time $29 payment rather than a subscription.
