Free Whatnot Profit Calculator

Whatnot charges sellers two main fees on every transaction. The first is the platform seller fee of 8%, calculated on the total sale price. This fee covers access to Whatnot's marketplace, live-streaming infrastructure, and built-in buyer audience. Whether you're selling trading cards, sneakers, or vintage collectibles, this 8% applies across all categories.

The second fee is payment processing at 2.9% + $0.30 per transaction. This covers credit card and payment handling through Whatnot's payment system. Combined, a $30 sale on Whatnot costs you roughly $3.57 in fees — about 11.9% of your sale price.

But fees are only part of the equation. To understand your true Whatnot profit, you need to factor in your cost of goods sold (COGS) — what you paid for the item — and shipping costs. Many sellers underestimate shipping expenses, especially for heavier items like sealed booster boxes or electronics. If you charge buyers for shipping, that offsets your cost, but you should still track it carefully.

That's exactly why we built this free Whatnot profit calculator. It gives you a clear picture of your real margins before you go live. Enter your sale price, costs, and shipping to instantly see your net profit, margin percentage, and a visual breakdown of where your money goes.

For sellers running multiple shows per week, tracking profitability at the item and show level is critical. Use the Per-Show Mode above to estimate your total show profit based on average values. And when you're ready to automate this across every show, LiveSellerOS does it for you — automatically calculating profit, tracking inventory, and generating reports so you can focus on selling.
