CrosslistySell-through rate calculator
Sell-through is the share of listings that end in a sale: sold, divided by sold plus active plus ended unsold. Enter those counts for an item you’re thinking of buying. As many sold as active works out at 50%, which many sellers treat as a good sign.
The shortcut: A slow seller gets more chances on more marketplaces. Crosslisty copies the listing for you.
Add to Chrome, free- 50% means one item sold for each one still listed.
- Compare the same item over the same period.
- A high rate at a low price is not the whole story, so check profit too.
Updated October 2026. Crosslisty is a Chrome extension (it also works in Brave and Edge) that copies a listing to the other marketplaces, fills each form for you, and removes sold items from your other listings.
Where to get the numbers
- On eBay, search for the item and filter by Sold items for your sold count. Note the period it covers.
- Search again without the filter for your active count.
- If you use Terapeak Product Research, it can also show listings that ended without selling.
- Enter the counts above.
How to read the result
| Sell-through | Rule of thumb | |
|---|---|---|
| Fast mover | 50% or more | Buy with confidence if the profit works |
| Steady seller | 20% to 49% | Fine with good margin and space to store it |
| Slow seller | Under 20% | Buy only cheaply, or for a high price later |
These bands are a seller’s rule of thumb, not a standard. Sellers point out that good staples can show 15% to 20% and still sell within months, so the right number depends on your category.
Limits of the number
- Active listings can include relisted or duplicate items.
- Prices matter. A cheap listing may sell quickly while overpriced ones sit.
- A seasonal item looks different in summer and winter.
- Sold counts cover only the marketplace you checked.
