  • Payment processing fees add 2.9% + $0.30 per transaction on top of a commission.

  • Temporary promo periods occasionally drop fees to as low as 2% commission

Whatnot's commission fee structure

Whatnot takes a percentage of each sale as its commission fee. These whatnot seller fees vary depending on your location, the type of item sold, and whether you participate in special promotions. Let’s break down the details so you can calculate your potential earnings accurately.

Commission rates by country

Fees vary by region, making it essential for international sellers to understand the differences. Here’s an overview of Whatnot’s 2025 commission structure:

  • United States: For transactions in the U.S., there is an 8% standard fee for the service, plus a 2.9% payment processing fee, and an additional $0.30 per transaction. These fees cover the cost of managing and processing payments securely and efficiently. 

  • Canada: In Canada, the fees are structured similarly with an 8% standard service fee, a 2.9% payment processing fee, and a flat $0.30 per transaction to ensure smooth payment handling and security. 

  • Australia: Australian transactions also incur an 8% standard fee, alongside a 2.9% payment processing fee and $0.30 per transaction, designed to maintain seamless operations and reliable payment processing. 

  • United Kingdom: In the U.K., the standard fee is 10%, combined with a 3.4% payment processing fee and £0.20 per transaction. These fees help ensure a secure and effective payment experience tailored to local standards. 

  • Germany: For transactions in Germany, there is a 10% standard service fee, plus a 3.4% payment processing fee, with €0.15 per transaction. This fee structure supports secure and efficient payment processes that are compliant with regional requirements.

Additional details: 

  • Whatnot’s payment partner manages payment processing fees. 

  • Sellers in Europe may experience slightly higher fees compared to North America. 

Occasionally, Whatnot offers special promotions designed to support sellers, such as: 

  • "Score 2% Fees Before Kickoff": These are limited-time events where seller fees are reduced to just 2%, offering significant savings. 

  • To take advantage of this promotion, sellers must sign up in advance to confirm their participation. 

  • These events are a great way for sellers to reduce their costs, increase their profit margins, and attract more buyers by offering competitive prices. 

These commission rates, like Etsy's seller fees, apply to the final sale price, which includes the total amount paid by the buyer, including shipping and taxes. This allows sellers to avoid extra fees for international shipping or customs charges. However, it’s worth noting that any chargebacks or fraudulent activity could lead to additional fees being deducted from the seller's account.

Payment processing fees and taxes

When calculating seller fees, be sure to account for payment processing costs and tax obligations. These extra expenses can affect your final payout, so understanding them upfront allows you to price your items more strategically.

How taxes affect your final payout

Taxes can take a noticeable chunk out of your earnings if you’re not prepared. Whatnot doesn’t withhold taxes for sellers, meaning you’re responsible for reporting and paying income tax on your profits. Here’s what that looks like in practice:

  • Income Tax: If you earn over $600 in a year, Whatnot will issue a 1099-K form. You’ll pay income tax based on your profit (revenue minus expenses like fees and shipping).
  • Sales Tax: Depending on your location, you may need to collect and remit sales tax. Some states require sellers to charge buyers sales tax if they have a physical presence or meet economic nexus thresholds.
  • Self-Employment Tax: If selling is your primary income, you’ll likely owe an additional 15.3% for Social Security and Medicare.

Tax laws vary by state and country, so consulting a professional or using tax software like TurboTax for online sellers can help avoid surprises. Keeping records of all fees and expenses ensures you only pay tax on actual profits.

Understanding additional cost factors

The seller's fees you see upfront don’t tell the full story. Hidden factors like shipping discounts and promotional deals can subtly eat into your profits if you’re not paying attention. Here are two key factors that often go unnoticed but can significantly impact your bottom line.

The real cost of free shipping

Offering free shipping might attract buyers, but it’s not actually free—you’re just moving the cost from the buyer to yourself. Here’s how it pencils out:

  • Example Sale: Let’s say you sell an item for $50 with free shipping included in the price. 
  • Shipping Cost: The cost to ship the item is $7.50, which is typical for small packages within the U.S. using standard shipping services. 
  • Whatnot Fees: Whatnot charges a platform fee of 8% of the sale price, which is $4. Additionally, there’s a payment processing fee of 2.9% of the sale price plus $0.30, totaling $1.75. 
  • Net Before Shipping: After deducting the Whatnot fees, your net amount before considering shipping costs is $50 - $4 (platform fee) - $1.75 (payment processing fee) = $44.25. 
  • Final Profit: Finally, subtract the $7.50 shipping cost from your net to calculate your total profit. $44.25 - $7.50 = $36.75. 

Without free shipping, you would charge the buyer the item cost plus shipping. Your fees would be slightly higher, but your final profit would still be significantly higher after all deductions. This shows that offering free shipping can reduce your earnings by a notable percentage.

Coupons and Promotions Impact

Discounts and promotions can be a great way to attract buyers, but they come with some hidden costs on platforms like Whatnot. It's important to understand that Whatnot calculates fees based on the original item price, not the discounted price. This can significantly impact your profit margin. Let’s break it down with an example:

Imagine you’re running a 20%-off promotion on an item priced at $100: 

  • Original Price: $100 
  • Discount: 20% ($20 off) 
  • Buyer Pays: $80 
  • Platform Fees: Whatnot charges 8% of the original price ($100), which equals $8. 
  • Payment Processing Fees: Payment processing fees also apply, calculated as 2.9% of the discounted price ($80) plus a $0.30 flat fee, for a total of $2.62. 
  • Final Profit: After deducting the platform fees and payment processing fees, you’re left with $69.38.

So, while discounts are great for boosting sales and attracting more buyers, it’s crucial to factor in how fees are applied so you can accurately assess your profitability. Always calculate the true impact of discounts on your bottom line to avoid surprises.

Calculating your potential earnings

Seeing the numbers in action makes it easier to understand how seller fees affect your profits. Let’s break down a few examples to show what you’ll actually earn from various sales.

Example profit calculations

$15 trading card with free shipping

Selling inexpensive items like trading cards can still be profitable if you manage costs carefully. Here’s how it breaks down: 

  • Sale price: $15 (set by you) 

  • Whatnot fee (8%): $1.20 (a small fee to use the platform) 

  • Payment processing (2.9% + $0.30): $0.74 (standard transaction fee) 

  • Shipping cost (you cover): $3.50 (since free shipping is offered) 

  • Final profit: $9.56 (a solid margin for lower-priced items) 

$100 collectible with buyer-paid shipping

Higher-priced items like collectibles often bring in a larger profit, especially when the buyer covers shipping: 

  • Sale price: $100 + $8 shipping (shipping is added to the final cost for the buyer) 

  • Whatnot fee (8% of $108): $8.64 (calculated on the total cost including shipping) 

  • Payment processing (2.9% + $0.30): $3.43 (a small deduction for payment services) 

  • Final profit: $95.93 (a significantly larger return thanks to buyer-paid shipping) 

$500 electronics bundle with a 20% off coupon

Discounted bundles can still generate strong profits, even with a promotional offer: 

  • Original price: $500 (the full value of the product) 

  • Discounted price: $400 (after applying the 20% off coupon) 

  • Whatnot fee (8% of $500): $40 (based on the original price, not the discounted amount) 

  • Payment processing (2.9% + $0.30): $11.90 (standard fee) 

  • Final profit: $348.10 (despite the discount, still a great margin for high-ticket items) 

These examples show how understanding fees and shipping costs can help you maximize your profit across a range of item types and price points.

Whatnot Fees vs Other Platforms

When it comes to selling online, fees can significantly impact your bottom line. Here’s how Whatnot compares to other popular platforms in the U.S. based on selling and payment fees for a $100 sale:

Whatnot 

  • Selling Fee: 8% of the item’s sale price. 

  • Payment Fee: 2.9% of the total sale price plus a flat fee of $0.30 per transaction. 

  • Total Fee: $10.90 for a $100 sale. Whatnot offers a competitive fee structure, making it an attractive platform for sellers looking to keep costs low. 

Mercari 

  • Selling Fee: 10% of the item’s sale price. 

  • Payment Fee: 2.9% of the sale price plus a flat fee of $0.50 per transaction. 

  • Total Fee: $12.90 for a $100 sale. Mercari provides a straightforward process but at slightly higher fees than Whatnot. 

eBay

  • Selling Fee: 13.25% of the item’s sale price, which may vary depending on the category.

  • Payment Fee: A flat fee of $0.30 per transaction. 

  • Total Fee: $13.55 for a $100 sale. eBay’s fees reflect its global reach and large buyer base, but they are on the higher end. 

Poshmark

  • Selling Fee: 20% of the item’s sale price, or a flat $2.95 for sales under $15. 

  • Payment Fee: Included in the selling fee structure. 

  • Total Fee: $22.95 for a $100 sale. Poshmark’s fees are the highest, but the platform’s loyal audience and focus on fashion make it a great option for clothing and accessories. 

*eBay fees may vary depending on the product category or additional promotions.

Compared to other platforms, Whatnot has a unique fee structure. Instead of charging a percentage or flat rate, Whatnot only takes a 5% commission on the final sale price for items over $25. This means that sellers keep more of their profits and can potentially make more money on the platform.

Final thoughts

Understanding whatnot seller fees gives you the power to price strategically and maximize profits. From commissions to taxes, every percentage point matters when selling collectibles or electronics at live auctions. The key takeaway? Factor in all costs—especially hidden ones like promotions and "free" shipping—before setting your sale price.

  • Start tracking fees per item in a spreadsheet to spot patterns and adjust pricing.

  • Test sales with and without promotions to compare actual profit margins.

  • Bundle low-cost items to offset shipping expenses on high-fee transactions.

  • Set price minimums that account for worst-case fee scenarios (promos + free shipping).

  • Review tax deductions—seller fees and shipping costs may reduce taxable income.

For sellers balancing multiple platforms, comparing Whatnot's rates with other marketplaces can reveal where your margins work best. Solid pricing starts with knowing the numbers. Run the math, adjust your strategy, and keep selling confidently.
