Fees and take-home
Whatnot Fee Calculator
Estimate US Whatnot earnings after commission, processing, fee taxes and seller-paid shipping. Tiered commissions took effect September 21, 2026 for existing sellers. Sellers granted selling access after September 21 enter the new structure at local midnight on the following Monday. If your current Seller Hub rate differs from a baseline below, choose Custom and enter it; this tool does not infer your tier. Commission uses item price, while processing uses the buyer's full checkout.
Formula
- Gross item sales = Average item final sale price * Checkout transactions
- Commission base = Item final sale price only (shipping and buyer tax excluded)
- Standard commission = Item final sale price * 8%
- Custom commission = Item price * current Seller Hub rate; only cap the base at $1,500 when you confirm the promotion applies to this order and rate
- Eligible high-value promotion commission = min(Item final sale price, $1,500) * category rate
- Payment processing base per transaction = Item final sale price + Buyer-paid shipping + Buyer-paid tax
- Payment processing = 0 when the processing base is $0; otherwise (Processing base * Processing rate + Fixed processing fee) * Checkout transactions
- Tax on commission = Commission * Commission tax rate
- Tax on payment processing = Payment processing * Processing tax rate
- Total tax on Whatnot fees = Tax on commission + Tax on payment processing
- Per-checkout commission, processing, and fee-tax amounts are rounded to the nearest cent before multiplying by checkout transactions
- Net earnings = Gross item sales - Commission - Payment processing - Tax on fees - Seller-paid shipping
- Effective deduction rate = Total deductions / Gross item sales * 100
Examples
- A $50 US standard-category sale with $5 shipping and $3.70 buyer tax has a $4.00 commission and about $2.00 in payment processing, leaving about $44.00 before seller-paid shipping or tax on fees.
- A $2,000 eligible high-value sale charges 8% commission on the first $1,500 under the current promotion, while payment processing still applies to the full checkout value.
- A $50 Coins & Money sale uses the reduced 4% commission but keeps the standard payment-processing layer.
When to use this calculator
- Price a Whatnot auction or Buy It Now listing after seller fees.
- Compare standard categories with Coins & Money or an eligible high-value order.
- See how buyer-paid shipping and tax raise processing fees without raising commission.
Common mistakes
- Applying the commission percentage to shipping and buyer tax; Whatnot commission uses the item final sale price.
- Applying payment processing only to the item price; the buyer's checkout value usually also includes shipping and tax.
- Using the high-value promotion for a category that is not eligible or after the promotion changes.
- Applying one blended tax rate to both fee layers even when the seller's state taxes only commission or only payment processing.
Frequently asked questions
What fees does Whatnot charge US sellers?
Whatnot charges commission on item price and processing on the buyer's checkout. The US standard baseline is 8%, with a separate 2.9% + $0.30 processing layer. Existing sellers entered category-specific volume tiers on September 21, 2026; use Custom for the current rate shown in Seller Hub. Category reductions, promotions and fee taxes can change the total.
Why are commission and payment processing calculated on different amounts?
Whatnot commission is based on the item's final sale price and excludes buyer-paid shipping and tax. Payment processing is based on the buyer's total checkout value, which usually includes the item price, buyer-paid shipping, and buyer-paid tax. That is why two sales with the same item price can have different processing fees.
How does the high-value order promotion work?
Under the limited-time promotion that started January 14, 2026, Whatnot charges the normal category commission on the first $1,500 of an individual sale and 0% commission on the portion above $1,500. Payment processing still applies to the full checkout value. As of July 2026, the listed categories are Comics & Anime, Toys & Hobbies, Coins & Money, Trading Card Games, Entertainment Cards, Sports Singles subcategories (sports breaks and Surprise Products are excluded), Bags & Accessories, and Jewelry & Watches. Eligibility and timing can change, so verify the promotion on Whatnot before using it for a pricing decision.
What commission applies to Coins & Money?
The Coins & Money baseline is 4%; an active tier or account promotion may be lower. For that case enter your current rate in Custom. Processing and fee taxes remain separate, and high-value eligibility must be checked for the order and rate before selecting the cap.
Why does Seller Hub show me a commission rate below 8%?
Tiered commissions took effect for existing sellers on September 21, 2026 at local midnight. Sales in one 28-day period determine the next period's tier; crossing a threshold does not immediately lower the current rate. Choose Custom and enter your current Seller Hub rate, not its projected next-period rate. Processing remains separate.
When do new sellers enter the tiered commission structure?
If you were granted selling access after September 21, 2026, the new commission structure starts at 12:00 a.m. in your local time on the following Monday. Confirm your activation and current rate in Seller Hub, then enter that rate in Custom. This calculator does not infer your start date or switch rates automatically.
How should I account for the Premier Shop discount?
Eligible Premier Shop sellers keep the additional commission discount through October 31, 2026. From November 1, 2026, Premier Shop no longer includes that discount. In Custom, enter the final applicable commission rate shown for your order in Seller Hub; do not subtract the discount again. This calculator does not apply a separate Premier Shop reduction or determine your eligibility.
Can I combine a Custom rate with the $1,500 promotion?
Only when Whatnot confirms that the promotion applies to both your order and that rate. Custom defaults to No cap. If confirmed, select Confirmed $1,500 cap: only the commission base is limited, while processing uses the full buyer checkout. This is a manual scenario, not automatic eligibility or promotion-stacking advice.
Why does the calculator include buyer-paid shipping and tax?
Those amounts normally increase the total checkout value used for payment processing even though they do not increase the commission base. Enter average buyer-paid shipping and buyer tax per checkout transaction to estimate the processing fee more realistically.
Does Whatnot charge tax on its seller fees?
In some seller locations, Whatnot must collect tax on commissions, payment-processing fees, or promotion fees, and the taxed fee types differ by state. Per Whatnot's tax page (July 2026), commission is taxed in DC, Hawaii, New Mexico, and West Virginia, while payment processing is taxed in Connecticut (special 1% rate), Hawaii, New Mexico, Ohio, South Dakota, Texas (standard rate reduced by 20%), and West Virginia. The calculator therefore provides separate optional commission-tax and processing-tax inputs. Leave a field at zero when that fee type is not taxed, enter the applicable rate when it is, and verify the treatment shown for your location.
Why does a zero-value checkout show no processing fee?
The fixed payment-processing charge applies to a checkout value that the buyer actually pays. When item price, buyer-paid shipping, and buyer-paid tax are all zero, the calculator treats the processing base as zero and does not add the fixed charge. This covers a no-payment giveaway scenario; seller-paid shipping can still reduce the seller's net.
How are bundled purchases handled?
Whatnot states that fees are applied when the buyer checks out. Purchases made separately are still calculated as separate transactions even if they are later bundled into one order or shipment. Enter the number of checkout transactions, not the number of final shipping boxes.
Why might my Whatnot payout differ from this estimate?
Your payout can differ because of category promotions, seller- or platform-funded coupons, taxes on fees, cross-border shipping, refunds, chargebacks, boosts, shipping-label adjustments, or free and reduced shipping. Compare the estimate with the receipt and earnings details in Whatnot Seller Hub for the specific order.

- US seller scenario. Standard commission is applied to the item's final sale price, excluding shipping and buyer-paid tax.
- Payment processing defaults to 2.9% + $0.30 and is applied to the total checkout value, which usually includes the item sale price, buyer-paid shipping, and buyer-paid tax.
- Coins & Money uses the published reduced 4% commission. The limited-time high-value promotion (0% commission on the portion above $1,500, started January 14, 2026) covers Comics & Anime, Toys & Hobbies, Coins & Money, Trading Card Games, Entertainment Cards, Sports Singles subcategories, and, since June 4, 2026, Bags & Accessories and Jewelry & Watches.
- The high-value promotion applies to Sports Singles subcategories only; sports breaks and Surprise Products are excluded. The promotion is temporary and Whatnot can change or end it at any time, so verify eligibility on Whatnot before relying on it for pricing decisions.
- Existing sellers entered the tiered structure on September 21, 2026 at local midnight. Completed sales in the preceding 28-day period determine the next period's rate, which stays locked during that period. Opening tiers used August 24-September 20 sales. For sellers granted selling access after September 21, the new structure starts at 12:00 a.m. local time on the following Monday. Check activation in Seller Hub. Use Custom with the CURRENT rate shown there, not the projected next-period rate. No automatic tier eligibility is calculated here.
- Eligible Premier Shop sellers keep the additional commission discount through October 31, 2026; from November 1, 2026 that benefit ends. Enter the final applicable rate shown for your order in Seller Hub. Do not subtract the Premier Shop discount again; this calculator does not apply it separately.
- Taxes on Whatnot fees vary by seller location and fee type. Enter a commission-tax rate only when your state taxes commission, and enter a processing-tax rate only when it taxes payment processing. Whatnot lists a special 1% processing rate for Connecticut and a standard rate reduced by 20% for Texas. Both fields default to zero; verify the rate shown for your location.
- Fees are calculated per checkout transaction even when purchases are later bundled into one order or shipment. The calculator rounds each per-checkout fee and fee tax to cents before multiplying by the transaction count, matching the currency precision shown in Whatnot's official examples.
- Promotional commission rates, coupons, cross-border orders, refunds, chargebacks, boosts, and shipping-label adjustments are not modeled automatically.
