Whatnot Fee Calculator

Calculate the Whatnot commission fee and payment processing fee along with your earnings and profit in seconds.

Whatnot Fee Calculator by Sidekick Tools

If you’re selling on Whatnot, one of the most important questions you might ask yourself before every live show is: how much will Whatnot take from my sale?

Many Whatnot sellers focus on gross sales numbers during a live stream, but revenue is not profit. Between the Whatnot commission fee, payment processing fee, and shipping costs, your actual earnings might look very different from what you expected.

That’s exactly why this Whatnot fee calculator exists. It helps you calculate:

  • Whatnot seller fee (commission fee)
  • Payment processing fee
  • Total Whatnot fees
  • Net earnings
  • Actual profit
  • Profit margin

So, instead of guessing, you’ll know exactly how much you’ll keep before you make a sale on Whatnot.

How Our Whatnot Fee Calculator Works?

Step 1: Select Your Country

Start by choosing your country (United States, Canada, Australia, or Europe).

This matters because Whatnot commission fees and payment processing fees vary by country. The Whatnot fee calculator by Sidekick Tools will use your selected country to apply the correct selling fees.

Step 2: Choose the Item Category

Next, select the category of the item you’re selling.

Why this is important:

Whatnot seller fees are not always the same across all categories. For example:

  • Standard items have a higher commission fee.
  • Coins & Money have a lower commission fee.

Once you select the category, the calculator automatically applies the correct Whatnot commission fee for that type of product.

You don’t need to look up the percentage yourself.

Step 3: Enter the Item Sale Price

Next, you have to enter the price you expect the item to sell for.

If you’re running an auction, use a realistic estimate — not your ideal price.

This number is used to calculate:

  • Whatnot commission (percentage of sale price)
  • Part of the payment processing fee

The higher the sale price, the higher the commission — because it’s percentage-based.

Step 4: Enter Your Cost of Goods

This is the amount you originally paid for the item.

This step is crucial.

Without entering your cost, you can’t calculate real profit — only revenue after fees.

For example:

  • Sale price: $100
  • Fees: $12
  • You receive: $88

That looks good.

But if your cost was $75, your actual profit is only $13.

The calculator subtracts your cost automatically so you can see true profit — not just payout.

Step 5: Enter Shipping Charged to Buyer

This is the amount your buyer pays for shipping.

Many Whatnot sellers assume shipping doesn’t affect fees. But payment processing fees apply to the total transaction amount — including shipping.

So if the buyer pays $10 shipping, processing fees may apply to that $10, too.

The Whatnot shipping fee calculator factors this in automatically.

Step 6: Enter Your Actual Shipping Cost

Finally, you need to enter what you will actually pay for shipping.

This includes:

  • Postage
  • Packaging materials
  • Any label costs

This step is important because:

If you charge $10 shipping but your real cost is $9, your actual shipping profit is only $1 — and that may shrink further after processing fees.

The Whatnot profit calculator subtracts your true shipping cost from your earnings so you see accurate profit.

Benefits of Using the Whatnot Fee Calculator

Get Crystal-Clear Profit Numbers Before You Go Live

When you sell on Whatnot, the sale price you see is not the amount you keep. The platform charges a commission fee along with payment processing fees, and those fees can affect your final payout. 

The Whatnot fees calculator removes the guesswork by instantly showing your net earnings and profit after all fees. Instead of estimating profits in your head or calculating manually, you get precise numbers in seconds. 

This clarity helps you understand your real profits, plan cash flow better, and avoid surprises when payouts arrive in your bank account.

Set Smarter Starting Bids That Protect Your Margins

Choosing the right starting bid is very important in live selling on Whatnot. If you start too low without factoring in selling fees, you risk shrinking your profit or even losing money. 

A Whatnot fee calculator helps you determine your break-even point before your auction begins. Once you know that number, you can confidently set starting bids that attract buyers while still protecting your margins. 

This approach keeps your pricing strategic rather than emotional. Over time, consistently pricing with fees in mind will ensure that every sale contributes positively to your overall revenue instead of quietly eating away at your earnings.

Prevent Emotional Pricing During Fast Auctions

Live auctions on Whatnot happen quickly, and the excitement often influences decision-making. When bids slow down, sellers often feel pressure to let an item go just to maintain momentum. 

Without knowing your numbers, you might accept a final bid that barely covers costs. By using the Whatnot fee calculator beforehand, you establish a minimum acceptable price for each item. This gives you a clear boundary during the auction. 

Instead of reacting emotionally, you make decisions based on data. That discipline protects your profits, builds long-term sustainability, and ensures your live shows remain both engaging and financially rewarding.

Compare Whatnot’s Fees with Other Marketplaces

Many resellers list their items on multiple marketplaces such as eBay and Poshmark. Each marketplace has its own fee structure, which directly affects the earnings of resellers. 

Using the Whatnot fee calculator helps resellers to compare earnings across marketplaces by calculating what you would actually keep from the same sale price. This makes it easier to decide where specific items perform best. 

Instead of assuming one marketplace is more profitable, you rely on actual numbers. Smart comparisons help you allocate inventory strategically and maximize overall returns across all your selling channels.

Plan Growth and Scale with Data

As your Whatnot business grows, small fee differences become more impactful. Losing just a few dollars per item may not seem significant at first, but across dozens or hundreds of sales, those losses add up quickly. 

A Whatnot fee calculator helps you project earnings based on different pricing strategies and sales volumes. This allows you to forecast revenue, plan inventory purchases, and set realistic financial goals. 

Instead of relying on rough estimates, you base your reselling growth strategy on solid numbers. That data-driven approach makes scaling more predictable, sustainable, and ultimately more profitable over time.

Why Most Sellers Miscalculate Whatnot Fees?

Ignoring Payment Processing Fees

It’s common for sellers to calculate the standard Whatnot commission but forget about the 2.9% + $0.30 payment processing fee (for US, Canada, and Australia) or 2.42% + €/£0.25 payment processing fee (for EU & UK Seller). 

Even though it may seem small on a $10 sale, it adds up fast on multiple items or high-ticket sales.

For example, if you sell 10 items at $50 each, that extra $0.30 per transaction plus 2.9% could reduce your total earnings by $15–$20 — money you might have thought was profit.

Missing payment processing fees can make your “profit” numbers look better on paper than they really are.

Not Tracking Cost of Goods

Many Whatnot sellers focus on what the buyer pays and overlook how much the item costs to source. If you buy an item for $40 and sell it for $50, you might think you made a $10 profit. But after fees and shipping, your margin could shrink to $2–$3.

The danger is that over time, this erodes your overall profitability. Sellers who don’t track the cost of goods end up thinking they’re profitable when, in reality, they’re just generating revenue.

Underestimating Shipping

Shipping isn’t just a flat fee; it includes:

  • Packaging materials (boxes, bubble wrap, tape)
  • Shipping labels
  • Dimensional weight adjustments

Many Whatnot sellers assume the amount charged to the buyer is pure profit. But if shipping costs are higher than expected, or if dimensional weight is miscalculated, that “extra” you thought you earned will vanish.

Starting Auctions Too Low

Low starting bids may attract buyers and increase engagement, but they can destroy margins if the item doesn’t sell at the intended price. 

Many Whatnot sellers often underestimate how a low starting price, combined with selling fees and shipping, can make a sale barely break even.

Without factoring in fees and costs ahead of time, a “successful” sale may actually reduce your profit compared to what you could have made with proper pricing.

The Bottom Line

Without a Whatnot fee calculator, sellers are essentially operating in the dark. The difference between a truly profitable live show and a break-even show on Whatnot often comes down to small percentage miscalculations, things as simple as ignoring processing fees or mispricing shipping.

Using a Whatnot selling fee calculator ensures you know exactly what you keep after all costs, letting you price items strategically, protect margins, and run consistently profitable live sales.
