Calculate the Whatnot commission fee and payment processing fee along with your earnings and profit in seconds.
Selling live on Whatnot is exciting, but the numbers behind every sale can get confusing fast. Between commission, payment processing, and shipping costs, your actual profit is rarely the same as your sale price. This Whatnot fee calculator gives you a clear breakdown of exactly what you’ll keep, before you even go live.
Choose your country (US, Canada, Australia, or Europe) and the correct item category so we can apply the right Whatnot commission and processing fees automatically.
Add your expected sale price, your cost of goods, the shipping charged to the buyer, and your actual shipping cost. No manual fee lookups required.
The calculator shows your Whatnot commission fee, payment processing fee, total Whatnot fees, net earnings, real profit, and profit margin—so you always know what you keep.
Manually calculating Whatnot fees can get complex because you need to factor in commission, payment processing, shipping charged to the buyer, and your actual shipping cost. With the Whatnot fee calculator by Sidekick Tools, the process becomes quick and accurate.
Simply enter your sale details and the calculator will show you the Whatnot commission fee, payment processing fee, total fees, your net earnings, and your final profit.
For most standard categories in the US, Whatnot charges around 8% commission on the item price, plus a payment processing fee of approximately 2.9% + $0.30 per transaction.
For categories like Coins & Money, the commission is lower (around 4%), with the same 2.9% + $0.30 processing fee. Fee structures for EU, UK, Canada, and Australia are similar but with region-specific rates.
If your item is in a standard category, the Whatnot commission on a $100 sale is usually about $8. After adding payment processing fees, the total amount that Whatnot takes is typically around $11–$12.
This means you'll receive roughly $88–$89 before subtracting your cost of goods and shipping costs.
No. Whatnot does not charge a listing fee. You only pay fees when an item actually sells on the platform.
Whatnot's commission is generally calculated on the item price, excluding shipping and taxes. However, payment processing fees are typically applied to the total transaction amount, which can include item price, shipping, and tax.
That's why the Whatnot fee calculator lets you enter both shipping charged to the buyer and your actual shipping cost—to give you a true picture of your profit.
In many categories, Whatnot fees are generally lower than eBay. For standard items, Whatnot's total fee is around 11–12% (commission plus payment processing), while eBay often charges around 13–15% depending on the category.
Using this Whatnot fee calculator alongside other marketplace calculators from Sidekick Tools makes it easy to compare net earnings across platforms.
If you're selling on Whatnot, one of the most important questions you ask yourself before every live show is: how much will Whatnot take from my sale?
Many sellers focus on gross sales during a live stream, but revenue is not profit. Between the Whatnot commission fee, payment processing fee, and shipping costs, your actual earnings may look very different from what you expected.
That's exactly why this Whatnot fee calculator exists. It helps you calculate:
So instead of guessing, you'll know exactly how much you'll keep before you make a sale on Whatnot.
Ignoring payment processing fees
Many sellers calculate the standard Whatnot commission but forget about the 2.9% + $0.30 (or 2.42% + €/£0.25) payment processing fee. It may look small on one sale, but across multiple items or high-ticket sales it adds up quickly and quietly eats into your profit.
Not tracking cost of goods
If you only look at what the buyer pays and not what you paid to source the item, your profit numbers will always be off. The calculator forces you to factor in cost of goods so you see real profit, not just revenue.
Underestimating shipping
Shipping is more than just the label price. Packaging, dimensional weight, and unexpected carrier adjustments can all reduce your margins. The Whatnot fee calculator separates shipping charged to the buyer from your actual shipping cost, so you can see exactly where money is made or lost.
Starting auctions too low
Low starting bids can boost engagement, but if you don't factor in fees and costs ahead of time, you may end up barely breaking even or even losing money. Knowing your break-even price helps you set smarter starting bids.
Without a Whatnot fee calculator, you're essentially operating in the dark. The difference between a profitable live show and a break-even one often comes down to a few percentage points, a miscalculated fee, or underestimated shipping.
Using this Whatnot selling fee calculator ensures you always know what you keep after all costs. That means smarter pricing, protected margins, and consistently profitable live sales.
