eBay sell-through rate: how to calculate it and use it to choose what to list

What is eBay sell through rate?

eBay sell through rate is a measure of demand compared with supply: of all the listings for a product over a period, how many led to a sale. If 40 units of a product sold in the last 90 days and 100 listings for it are live now, many sellers would call that a 40% sell-through rate. A high figure suggests buyers are absorbing the supply; a low one suggests many sellers are competing for a small number of buyers.

Resellers often shorten it to STR. It is not an official eBay metric that appears on your listings, and eBay publishes no target figure for it. It is a research tool you calculate yourself, or read from eBay's Product Research tool, to compare products before you commit time and listings to them.

How do you calculate sell-through rate on eBay?

There are two common versions. Use one consistently, because they give different numbers for the same product.

Version 1: sold divided by active

Sell-through rate = number sold in a period ÷ number of active listings now × 100

This is the quick method. Search for the product, count the active listings, then tick the "Sold items" filter and count the sales over the period eBay shows. It is easy to do from the search page, but it mixes a period of sales with a snapshot of listings, so treat it as a rough guide.

Version 2: sold divided by sold plus unsold

Sell-through rate = number sold ÷ (number sold + number that ended unsold) × 100

This method looks only at listings that finished in the period. It answers a slightly different question: of the listings that ended, how many found a buyer? Product research tools tend to work closer to this method, but check how any tool defines its figure before comparing it with your own sums.

Worked example: comparing three products

Example (hypothetical numbers): suppose you are choosing between three kitchen products, and you count sold and active listings on eBay UK for each, using the same 90 day window.

The pasta rack has the highest rate, but only 15 sales in three months. Even a strong listing would share a small market. The spice grinder combines a good rate with real volume and a higher price, which leaves more room for profit after fees. The baking mats sell in the largest numbers but face heavy competition. Sell-through is the start of the decision, not the end of it.

What is a good sell-through rate on eBay?

There is no official answer, and any single cut-off you read online is a rule of thumb from one seller's experience. A sensible way to judge a figure is to ask three questions:

• Compared with what? Compare products within the same category and price band. A collectable and a phone cable live in different markets.
• With how much volume? A high rate on a handful of sales tells you less than a decent rate on hundreds.
• At what price? A product that sells through well only at a price below your costs is not an opportunity for you.

Seasonality adds a fourth question: when? A product's sell-through can swing a long way across the year. Garden furniture, advent calendars and school uniform items all have clear peaks. If you research a seasonal product, check its sold data for the same point last year in Product Research, as well as the last few weeks, and plan your listing so it is live and has some history before the peak arrives.

For dropshippers, a reasonable working approach is to rank candidate products by sell-through within a category, then filter that list by your profit per sale. The products near the top of both lists are where to start.

How should you use sell-through rate when choosing products?

1. Search the exact product, using the words buyers would use, and set the location filter to your own country so you compare the market you sell into.
2. Exclude what does not match. Remove used items if you sell new, and remove bundles or different models that would distort the count.
3. Count sold and active over the same window and calculate the rate.
4. Note the price range of sold items. The prices buyers actually paid matter more than asking prices.
5. Calculate your profit at a price inside the sold range, after eBay fees, ad costs and a returns allowance.
6. Check the competition's quality. If many active listings have poor photos, thin item specifics or slow handling times, a better listing may win share.
7. Shortlist and list a small number, then measure your own sales against the rate you expected.

Product Research in Seller Hub can speed up steps 3 and 4. It shows sold data, average prices and a sell-through figure for a search term over a chosen period. Our guide to how eBay's search ranks listings covers what makes a listing win once you have chosen the product.

Can you calculate sell-through rate for your own shop?

Yes, and it is one of the most useful numbers you can track. For your own store, use: items sold in the month divided by the average number of active listings in that month. Track it monthly and by category. A falling rate in one category can be an early sign of new competition, a price problem or a supplier stock issue, long before it shows up clearly in your total sales.

A related measure is sales per listing per month, which counts multiple sales of the same listing. For a dropshipping catalogue of fixed price listings with several units each, that figure is often more practical, because it shows how much work each listing is really doing.

How to raise your own shop's sell-through

If your own rate is low, the cause is usually one of a handful of things, and each has a fix you can test:

• Too many weak products. End listings that have had almost no views for a long period and replace them with products that match the profile of your best sellers.
• Listings that are seen but not chosen. If a listing gets plenty of impressions and views but few sales, check its total price against sold items, then its photos and its first lines of description.
• Listings that are not seen. Few impressions point to relevance: the title, category and item specifics may not match what buyers search.
• Slow or vague delivery. A handling time longer than competitors' can lose sales even at a good price.
• Out of stock items still showing. Listings that cannot sell drag your figure down; set quantity to zero or end them.

Fix one cause at a time across a group of listings, note the date and compare the next month's sell-through for that group with the rest of the shop. That gives you a fair test without guesswork.

What are the limits of sell-through rate?

• It shows the past. A seasonal product can show a high rate in December and a poor one in February.
• Search terms shape the count. A broad search mixes different products; a narrow one may miss listings described differently.
• It ignores who sold. A few established sellers with long feedback histories may take most of those sales.
• It ignores sourcing. A product only helps you if you can source it legitimately. eBay allows dropshipping from a wholesale supplier, but listing an item and then buying it from another retailer or marketplace that ships directly to your buyer is not allowed, as eBay's drop shipping policy says. You also stay responsible for delivery and buyer satisfaction.
• It ignores rights. Some brands are protected through eBay's VeRO programme. Check brands before listing; our VeRO checker page explains how brand screening works.

A sell-through checklist

• Use one calculation method and stick to it.
• Compare products within the same category, price band and condition.
• Look at volume and sold prices, not only the percentage.
• Check profit after fees at a realistic sold price.
• Recheck seasonal products at different times of year.
• Track your own shop's sell-through monthly, by category.
