Whatnot fees explained — the real cost of every sale.

Whatnot advertises an 8% commission. Most sellers price as if that's the whole fee. It isn't — the stacked reality is closer to 12.7% on a typical $25 sale with shipping, and climbs higher when refunds, chargebacks, and platform promos hit. Here's the full breakdown.

The 2 real fees Whatnot charges

Whatnot's seller-side fees break into two components.

1. Seller commission — 8% of (item + shipping)

Whatnot takes 8% of the total order value, and this is the line most sellers misread. The 8% applies to the item price plus the shipping charged to the buyer — not just the item. So if you charge $5 shipping on a $25 item, Whatnot's commission is 8% of $30 ($2.40), not 8% of $25 ($2.00).

2. Payment processing — 2.9% + $0.30 per order

Standard card-processing rates apply on top of the commission. Again calculated on the full order total (item + shipping). On a $30 total that's $0.87 + $0.30 = $1.17.

Worked example: $25 item with $5 shipping

So the buyer pays $30. You actually bring in $26.83 before subtracting the cost of goods and your own shipping costs. The fee burden is 10.57% of the total order — or 12.7% of the item price.

The hidden costs most sellers miss

The advertised fees are only the top of the stack. The full cost model has 8 components:

• Commission (8%) — covered above
• Payment processing (2.9% + $0.30) — covered above
• Shipping cost to you — buyer-paid shipping is a pass-through; you still pay the actual label, which is often higher than what the buyer paid
• Packaging materials — boxes, polymailers, tape, filler — typically $0.50–$1.50 per shipment
• Refunds and returns — Whatnot refunds buyers and recovers the fee portion, but shipping labels and repackaging come out of your pocket
• Refund reserve — plan 3–5% of revenue set aside to cover returns without cashflow stress
• Platform promos — discount codes and seasonal promotions often reduce your net without touching commission
• Cost of goods sold (COGS) — what you paid to acquire the inventory

How to price for the full fee stack

A simple rule of thumb: take your target net per item and multiply by ~1.15 before adding shipping. This absorbs commission, processing, packaging, and a refund reserve, leaving your real margin intact.

For example, if you want to net $20 on an item:

• Target net: $20
• Multiply by 1.15: list at $23 + shipping
• At a $28 order total: fees ≈ $2.24 + $1.11 = $3.35
• Your net after fees: $19.65 — close to the $20 target
