Whatnot seller fees and commissions: understand the net
Whatnot commission, payment processing, seller shipping, and margin impact: read the net in the Seller Weekly Orders Report, set price floors, and avoid surprises.
Key takeaways
- Whatnot fees (commission + processing) and shipping heavily hit real margin.
- CSV transaction_amount is typically already net of commission, processing, and seller shipping in the ledger.
- Without COGS you see net revenue but not estimated margin.
- Set a price floor before going live: COGS + approximate fees + minimum margin.
- Official fee schedules change — always verify the Whatnot Help Center.
- buyer_paid fuels the show; net decides whether the lot was profitable.
Direct answer: buyer-facing sales are not what hits your bank. Whatnot commission, payment processing, and seller shipping reduce the net — and without purchase cost (COGS), you still do not know margin.
This guide maps fee layers, shows how the CSV already reflects them, and gives a price-floor method you can use before every live. WhatCopilot is not affiliated with Whatnot: for exact rates, the official Help Center always wins.
Fee layers to know
Think in layers, not one magic percentage. Each layer reduces what remains after a winning bid.
- Whatnot marketplace commission (varies by category / program — see Help Center).
- Payment processing fees.
- Shipping / labels when you sell with seller shipping.
- Refunds (negative amounts in the ledger).
- Purchase / prep cost (COGS) — outside Whatnot fees, but critical for margin.
buyer_paid vs transaction_amount: the fee gap
buyer_paid is what the buyer pays. transaction_amount is what typically remains after commission, processing, and seller shipping in the ledger. The gap is not a bug — it is the cost of the marketplace.
- buyer_paid = $100
- Commission + processing + shipping ≈ $18 (illustrative)
- transaction_amount ≈ $82 (ledger net)
- If COGS = $50 → estimated margin ≈ $32
- If you “budgeted” $100 of sales, you were off-base

Reading the net in the Seller Weekly Orders Report
Each CSV row is a ledger transaction. In practice, transaction_amount is already a net figure (commission, processing, and seller shipping typically deducted). Refunds carry negative amounts. Deep dive: How to read your Seller Weekly Orders Report.
| Signal | Where to read it | Use it for |
|---|---|---|
| Buyer-facing sales | buyer_paid | AOV, marketing, show feel |
| Net revenue | transaction_amount | Real cash, post-fee totals |
| Estimated margin | net − COGS | Lot / live profitability |
| Refunds | order_refund | Offer & shipping quality |
After fees: compute margin
Net revenue ≠ margin. WhatCopilot estimated margin subtracts COGS (cost_of_goods) entered in Whatnot. Method and limits: Calculate your real Whatnot seller margin.
Set a price floor before going live
Fees are managed before you open the lot. Starting too low “for energy” turns a lively show into an unprofitable one.
Estimate the full lot cost
COGS + approximate fees + shipping. Use ranges if exact rates vary.
Add your minimum acceptable margin
That is your economic floor. Without it, you sell volume at a loss.
Open the auction above the floor
Or consciously go under (clearance, acquisition). Never by accident.
Verify CSV net after the show
Not only total buyer_paid. Adjust floors for the next live.
- COGS = $40
- Approx fees + shipping = $12
- Minimum margin = $18
- Floor ≈ $70 — do not open at $25 “to warm the chat”
Classic fee pitfalls
- Budgeting on buyer_paid as if it were cash.
- Forgetting refunds also wipe the “won” commission feeling.
- Copying another seller’s pricing without knowing their COGS.
- Never revising floors after a CSV import.

FAQ
- Where are official Whatnot fees listed?
- On the Whatnot Help Center (seller fees articles). Rates and exceptions change — do not rely only on third-party write-ups.
- Which CSV column is net revenue?
- transaction_amount on order_earnings / order_refund rows in the Seller Weekly Orders Report. buyer_paid reflects what the buyer paid.
- How does WhatCopilot handle fees?
- WhatCopilot starts from the CSV ledger: net revenue aggregates transaction_amount. Estimated margin = net revenue − COGS when cost_of_goods is filled.
- Are fees the same across every category?
- No. Commission and terms can vary by category, program, or region. Always cross-check official Whatnot docs before locking prices.
- How should refunds enter the math?
- order_refund rows carry negative amounts in the ledger. They reduce aggregated net — do not ignore them when reading a “record” show.
- Should I raise starting prices to cover fees?
- Often yes — with method: compute a floor (COGS + fees + margin), then test auction pace. A start that is too high can freeze the chat.
