WHATFEES / SELLER TOOLS
Whatnot fee calculator
Enter what your card, pack or box costs and the profit you want. Calculate the selling price needed to cover your costs and fees.
Calculate your selling price
Enter your cost and target profit to find the selling price you need after fees. Amounts are shown in CAD.
Advanced settings: fees, shipping and taxes
Illustrative defaults: 8% commission, 2.9% processing and $0.30 per order. Adjust these to your own rates.
Price with no profit: $67.68
Commission applies to the item price; processing applies to the item price plus buyer-paid shipping and tax. Cost should include your item cost, packaging and any shipping you cover. This estimate excludes refunds, discounts not entered in the sale price, and other charges.
Check your rate in Whatnot Seller Hub and the official fee policy.What goes into a fee estimate?
Start with your total cost and target profit percentage. The calculator finds the selling price needed to cover both after fees. Advanced settings let you adjust commission, payment processing, the fixed fee, buyer-paid shipping and taxes.
A $100 box is not $100 in your pocket
Using the example defaults, with no shipping, tax or other charges, a $100 sale has $11.20 in estimated fees. If your total cost is $60, the estimated profit is $28.80. Change the inputs to reflect your own category, market and costs; these are example assumptions, not a guaranteed Whatnot rate.
Why your category and sales tier matter
Use the commission rate shown in your own Seller Hub. Category, market, sales tier and promotions can change the rate. Payment processing still needs its own input. Check your final order breakdown after a sale rather than treating an estimate as a settlement.
Break-even and target-profit prices
With a $60 total cost, the example rates of 8% commission and 2.9% processing plus $0.30 per order give a break-even price of $67.68. A 20% profit target means $12 after fees and a required price of $81.15. These examples exclude shipping and taxes; the calculator rounds required prices up to the next cent.
