Break math, how much do Whatnot card breakers actually make?
The breaker income question gets answered with two extremes: clips of huge nights, and posts saying nobody makes money. The truth is in the arithmetic. Here's the real math, with worked examples for a single box, a full case, stalled spots, and a small product break, plus the per-hour view most breakers skip.

The simple formula
Net profit on any break = revenue − product cost − supplies − Whatnot fees − refunds − any shipping you cover. It is easy to track only the first two and get blindsided by the rest.
Pick a target margin before you price, not after. This guide uses 20% of revenue as its planning number. Your own target depends on how fast your spots sell, how much risk you carry, and what your hours are worth. Margin is only half the story; dollars per hour is the other half, and every example below shows both.
The fee rate depends on your spot price
Whatnot charges an 8% commission plus about 2.9% + $0.30 processing per order. Because the $0.30 is fixed, the all-in rate moves with spot size: about 15% on $7 spots, about 14% on $10 spots, and about 11.5% on $50 spots. Using one flat percentage for every break is the most common error in break math. The fee guide has the full table and the pricing formulas used here.
Shipping is left out of these examples on purpose. On Whatnot the buyer normally pays shipping at checkout and you print a prepaid label, so the costs you carry are product and supplies. If you offer free shipping, add it as a cost.
Example 1: a single hobby box, 32 random spots
Example numbers: a $120 hobby box of a football product, $8 in supplies, 32 team spots. Break-even is $4.83 a spot; a 20% margin needs $6.22, so the spots go up at $6.25.
- Revenue: 32 × $6.25 = $200.00
- Box: −$120.00
- Supplies (sleeves, toploaders, team bags, mailers): −$8.00
- Whatnot fees ($16.00 commission + $15.40 processing): −$31.40
- Profit: $40.60, a 20.3% margin
- If one spot gets refunded: $34.35
Now the hours. Prep, the show, sorting hits, and packing a single box can easily take an hour and a half. At 1.5 hours, $40.60 is about $27 an hour before refunds. Fine for a side hustle; thin for a living.
Put another way, every $1 of revenue in this break splits into 60 cents for the box, 4 cents for supplies, about 16 cents for Whatnot, and about 20 cents of profit. That is why product cost is the number to watch: if the box costs $10 more and the spot price stays put, profit drops by about a quarter.
Example 2: the same product by the case
A 12-box case of the same product at the same $120 a box: $1,440, plus $25 in supplies because more hits get shipped. Still 32 random team spots, but each spot now gets its team's cards from all 12 boxes. Break-even is $51.72 a spot; a 20% margin needs $66.69, so the spots go up at $67.
- Revenue: 32 × $67 = $2,144.00
- Case: −$1,440.00
- Supplies: −$25.00
- Whatnot fees ($171.52 commission + $71.78 processing): −$243.30
- Profit: $435.70, a 20.3% margin
- If one spot gets refunded: $368.70
Same margin as the single box, so the case is not magic on a percentage basis. What changes is everything around it. Fees fall from 15.7% of revenue to 11.3%, because the same 32 fixed charges are spread over far more money. And if the case takes about 3.5 hours end to end, that is roughly $124 an hour against $27. The catch: you need 32 buyers willing to pay $67 a spot, which takes an audience a single box does not.
Example 3: what stalled spots cost you
Back to the single box. Twenty-six spots sell at $6.25, then the show slows down and the last 6 go at auction for about $3 each.
- Revenue: 26 × $6.25 + 6 × $3 = $180.50
- Whatnot fees: −$29.27
- Box and supplies: −$128.00
- Profit: $23.23, down from $40.60
Six cheap spots cost 43% of the profit. The last few spots decide the night, which is why pricing for sell-through matters more than squeezing the top price, and why random breaks are easier to finish than PYT. More on that in break formats compared.
Example 4: a small product break
A $55 sealed product, such as a Pokemon Elite Trainer Box, split into 10 spots at $7, with $3 in supplies:
- Revenue: 10 × $7 = $70.00
- Product and supplies: −$58.00
- Whatnot fees ($5.60 commission + $5.03 processing): −$10.63
- Profit: $1.37
Break-even here is $6.85 a spot, and a 20% margin needs $8.83. The trouble is that buyers know roughly what the product costs, and $90 for ten spots of a $55 box feels steep. Small products work as an add-on inside a bigger show, or several boxes run together; on their own they rarely pay for the hour.
Dollars per hour, not just margin
Count every hour a break really takes: buying and receiving product, listing, the show, sorting hits by buyer, packing, printing labels, and dropping off packages. Divide profit by that number, not by the length of the show. Two breaks with the same margin can be worth very different amounts of your time, as the box and case examples show.
As a scenario, not a promise: running the case example twice a week would come to about $871 a week in profit before refunds and taxes, for two shows plus all the prep and shipping around them. Real numbers depend entirely on your product, your prices, and whether your audience fills the spots.
What kills breaker margins
- One flat fee percentage for every break. Cheap spots lose more to the fixed $0.30, so price with the rate for your spot size.
- Mispriced PYT tiers. Underprice the premium teams and you leave money on the table; overprice the bottom tier and it never sells.
- Opening before the break is full, then eating the unsold spots.
- Refunds from packaging and mix-ups. Every refund costs the sale, and the fees on it may not come back. Sleeve, toploader, and double-check the buyer before sealing a mailer.
- Paying retail for product. Once you run shows every week, the price you pay per box is one of the biggest levers you have.
- Slow shipping. Late packages hurt your seller rating and the repeat buyers your next break depends on.
Before you price your next break
- Add up product cost and supplies.
- Pick a spot count your audience can realistically fill.
- Work out break-even and your target price, using the fee rate for that spot size.
- Decide in advance what you will do if the last spots stall.
- After the show, log the real revenue, fees, and costs, so the next break is priced from facts instead of memory. The free break templates have a profit sheet for this.

Break math questions
How much do Whatnot card breakers make per break?
It depends on product cost, spot prices, and whether every spot sells. As a worked example, a $120 hobby box split into 32 spots at $6.25 brings in $200 and leaves $40.60 profit after the box, $8 of supplies, and $31.40 in Whatnot fees. A 12-box case of the same product at $67 a spot leaves $435.70.
What profit margin should a card break target?
Pick a target before you price. This guide plans at 20% of revenue, but the right number depends on how fast your spots sell, the risk you carry, and what your hours are worth. Check dollars per hour as well as margin.
Are case breaks more profitable than box breaks?
Not always by margin, but usually by the hour. In the worked examples both land near 20%, yet fees take 11.3% of the case's revenue against 15.7% for the box, and the case earns roughly $124 an hour against $27, as long as your audience can fill 32 spots at the higher price.
How do I work out a break-even spot price?
Divide product cost plus supplies by the number of spots, add $0.30, then divide by 0.891. That covers the 8% commission and about 2.9% + $0.30 processing on each spot. A $128 box-plus-supplies cost over 32 spots breaks even at $4.83.
