Reseller profit calculator
Every other profit calculator asks what the item will sell for. That is the number you do not know, and the one you get wrong, because you took it from a comp of an item in better condition than yours. This one asks for the comp AND what condition that comp was in, then moves the price to the condition your item is actually in. The adjustment comes from GradeThread's own Condition Index, which is built from active eBay listings rather than sold ones, with a spread wide enough that it is printed next to the average rather than hidden behind it.
The comp, and the item you actually have
What one like it actually sold for, not what one is listed at.
Comps skew clean. A photographed, well-described listing is usually a 9.

Estimated sale price $46.52
77.5% of the comp
The adjustment, in the open. A 9.0 sells for 83.7% of a mint example and a 7.0 for 64.9%, so your comp of $60.00 becomes $46.52, a change of $13.48 down. From the average curve across the Condition Index, which is built from active eBay listings.

What a grade is worth, measured
Median share of a mint price at each grade, across the GradeThread Condition Index, read on 2026-08-18. The Index is built from active eBay listings, so these are shares of asking price, not of sale price.
| Grade | Tier | Share of mint price | Range across items |
|---|---|---|---|
| 10.0 | New with Tags (NWT) | 100% | 100% to 100% |
| 9.5 | New without Tags (NWOT) | 100% | 100% to 100% |
| 9.0 | New without Tags (NWOT) | 84% | 53% to 100% |
| 8.5 | Excellent | 84% | 53% to 100% |
| 8.0 | Excellent | 74% | 42% to 100% |
| 7.0 | Very Good | 65% | 39% to 91% |
| 6.0 | Good | 56% | 35% to 83% |
| 5.0 | Fair | 44% | 26% to 74% |
| 4.0 | Poor | 31% | 18% to 56% |
| 3.0 | Poor | 20% | 6% to 42% |
Read the right-hand column before you trust the middle one. At grade 9.0 the range runs from 53% to 100% depending on the item, which is the difference between a good buy and a bad one. Grades 9.5 and 10 share a row, and so do 8.5 and 9, because the Index bands them together rather than because we rounded.
Everything above depends on the grade being right
You have just priced an item on a number you assigned yourself. Every seller grades their own stock generously, which is why buyers discount what a listing says about condition and why the same garment described as excellent by two people sells for two different prices. A standardized grade from photographs takes the estimate out of the most sensitive input on this page.

The comp you typed in was the hard part
Everything on this page rests on one number you had to go and find, for one item. FlipDesk pulls comparable eBay listings per item and keeps them condition-aware, so you are pricing an Excellent piece against comparable Excellent ones rather than against an average of mint and worn. It also says whether the number is an asking price or one of your own realized sales, which is the part that decides how much to trust it.
Common questions
- How do I work out resale profit?
- Sale price plus any shipping you charge, minus the marketplace's fees, minus what the item cost you, minus the postage you pay. The arithmetic is easy. The hard part is the sale price, which is why this calculator spends most of its inputs on getting that number honest rather than on the subtraction.
- Why does condition change the price so much?
- Because it is the largest single lever on a used garment, larger than the brand for anything below the designer tier. Across the Condition Index, a 7.0 is listed at a median 65% of what a mint example asks and a 5.0 at 44%. Price a 7.0 off a mint comp and you have overpriced it by a third before you started.
- What condition is a typical sold comp in?
- Better than yours, usually. Listings that sell well are the ones photographed carefully and described fully, which correlates with the item being in good shape. Assuming a comp is a 9 rather than a 10 is a safer default, and the calculator defaults to that.
- Is the condition adjustment the same for every item?
- No, and that is the most useful thing on this page. At grade 9.0 the share of mint price ranges from 53% to 100% across the items measured. Carhartt double knee pants are listed at the same price at 8.0 as at 10.0; a Lululemon Scuba hoodie loses 20% over the same drop. If your item is in the Condition Index, pick it and the calculator uses its own measured curve instead of the average.
- What margin should a reseller aim for?
- There is no universal number, but the shape of the answer is: your margin has to survive a return, and roughly one sale in ten comes back on most clothing platforms. A 15% margin does not survive that; a 40% one does. Run the calculator at the grade you think the item is and again a full point lower, and see whether the worse case still clears.
