How to calculate profit on Whatnot

Start with the winning bid, not the sale total

The number you see on screen when the hammer drops is gross revenue for that item. It is the top of the calculation and nothing more. Everything else in this guide is subtracted from it.

Log each item individually rather than totalling the show. Per-item profit is the only way to learn which categories are worth buying again, and a show-level total hides the items that lost money.

Subtract platform fees and payment processing

Platform commission and payment processing are charged per sale, so they belong on the item, not on the show. Treat them as a percentage of the winning bid plus any fixed per-transaction amount.

If a buyer wins several items in one order, allocate shipping and any order-level fee proportionally across the items in that order instead of putting the whole amount on the first line.

Subtract true cost of goods

For single items, cost of goods is what you paid plus any freight and prep allocated to it. For bulk lots, divide the total landed cost of the lot, including freight and any overhead you allocate, by the number of sellable pieces.

Lock the cost basis at the moment of sale. If you later re-price or restock the same SKU, historical profit should not silently change.

Subtract the costs everyone forgets

Shipping supplies, labels, thermal paper, mailers and inserts are a real per-item cost. Set a single per-item packaging figure and apply it to every sale.

Then set an hourly operating cost covering studio space, lighting, software and your own time. Multiply it by the length of the show and spread it across the items sold. A show that grossed well over four hours can still lose to a tighter ninety minute show.

Subtract host pay

If someone else is on camera, their commission or hourly rate comes out before you call anything profit. Commission should be calculated on the same per-item revenue you already logged so payroll and reporting never disagree.

What good looks like

Net margin, not gross margin, is the number to manage. Track it per item, per category and per host, and compare shows on net profit per hour rather than on gross revenue.

Streamalytix does this arithmetic on every logged sale while you are still live, so you can change the run order before the show ends instead of finding out next week.
