Marketplace Pricing Calculator

How it is calculated

The tool works backward from the profit you want to the price you must list. Because the marketplace takes its percentage from the sale price, not from your cost, the price is list price = (product cost + target profit) ÷ (1 − fee% ÷ 100) and marketplace fee = list price × fee% ÷ 100. Product cost is everything you pay per unit in dollars (item, shipping to the buyer, packaging), target profit is the dollar amount you want to keep per sale, and fee% is the combined percentage fee (referral plus payment processing) as a percent. There is no field for flat per-order or per-listing fees; add those to the product cost yourself. Negative cost, negative target profit or a negative fee give no result, and neither does a fee of 100% or more; as the fee approaches 100% the required price rises steeply (a 99% fee turns $25 of cost plus profit into a $2,500.00 price). Taxes, returns and advertising are not included.

Common mistakes

• Adding the fee percentage on top of cost plus profit. The fee is charged on the final price, so you must divide by (1 − fee), which gives a higher price than multiplying by (1 + fee).
• Forgetting flat fees such as per-order or listing charges. They are not a separate input, so add them to the product cost.
• Entering only the percent for the referral commission and leaving out payment processing or advertising fees. Use the full percentage the platform takes in total.
• Entering the profit you want as a percent. The target profit is a dollar amount per sale, not a margin.
• Trying a negative target profit to model selling at a loss. The tool gives no result for it; enter 0 to find the break-even price.
