SellNet: Fee & Profit Calc

SellNet is a fee and payout calculator built for resellers who list on eBay, Etsy, and Poshmark.

Solve payout:
Enter a listing price, your item cost, shipping, and whether you are running promoted listings, and see your exact net payout, profit, and profit margin after every marketplace fee.

Solve list price:
Enter the profit or payout you actually want, and SellNet works backward to tell you the listing price you need, correctly handling a mix of percentage fees, fixed fees, and Poshmark's tiered flat fee under $15.

Every fee rate is built in as an editable default, final value fee, payment processing, listing fees, promoted listing rate, so when a marketplace changes its fees, you update one number instead of redoing your math by hand. Add your own custom marketplaces too.

Keep a running history of your calculations so you can compare listings and see how fees eat into different price points.

SellNet works completely offline. Your pricing data never leaves your device, and there is no account.

Every feature is free for 14 days. After that, a single one-time purchase keeps it all. No subscription and no ads. You can export your history and fee rates as CSV at any time.

Fee rates shown are editable estimates and may not always match your current marketplace fee schedule exactly. Always confirm final fees with your marketplace before relying on the numbers for tax or accounting purposes.
