The problem

A sale on a Whatnot stream isn't what you keep. Commission, payment processing, the cost of the item, shipping supplies and your own label all come out before profit.

How it works

  1. Pick your region and category.
  2. Enter a lot: sale price, buyer shipping and tax, COGS, your shipping and supplies.
  3. See commission, processing, total fees, net payout and profit.
  4. For a whole show, drop a show CSV and review ok, thin and loss lots.
  5. Print the show-night sheet or download the results CSV.

FAQ

Is this affiliated with Whatnot?

No. It is an independent offline tool. Always verify fees in the Whatnot Help Center and your Seller Hub, which is the source of truth for payouts.

What's the difference between commission and processing?

Commission is a percentage of the item's final sale price only. Processing is a percentage of the order value (usually item plus buyer-paid shipping and taxes) plus a fixed fee.

Why don't my numbers match an order?

Promotions, cross-border details, giveaways, Sports breaks versus Singles or custom terms can differ. Check the region, category, processing base and fee constants.

Can I change the fee rates?

Yes, in Advanced fees. Changes are saved in your browser, and Reset to defaults restores the built-in set for the current region.

Does it work offline and on iPhone?

Yes. Open the file from Files or AirDrop. No network is needed, and printing uses the system print dialog.

Is it a subscription?

No. It costs $8, paid once on Gumroad. See the product page on Gumroad for its refund policy.
