How to use the sell-through rate calculator
- Enter the number of items that sold in “Items sold in the period”.
- Enter the number you still have for sale in “Items still listed”. Count them on the last day of the same period.
- Enter the length of the period in “Length of the period (days)”. The page starts at 30.
- Read “Sell-through rate”. It is sold divided by sold plus still listed, shown as a percentage.
- Read the line under it, which gives the days the listings still up would take to clear and the sales a day behind that estimate.
- Change one field at a time to see how the answer moves. With nothing sold, the page says the time to clear cannot be worked out.
The page opens with 30 sold, 70 listed and a 30-day period, so you can see the layout before you type your own numbers. For example, 60 sold and 40 still listed over 30 days gives 60% and 20 days to clear, while 20 sold and 80 listed over 14 days gives 20% and 56 days. Use the same period when you compare two results, and run one product line at a time, because mixing unrelated stock blurs the answer. There is no download or link button on this page. Write the result down, or keep a record in the reseller ledger.
What is sell-through rate?
Sell-through rate is the share of the items on offer that actually sold in a period. This page uses sold ÷ (sold + still listed). If 30 items sold and 70 are still listed, the rate is 30 ÷ 100, which is 30%. Platforms and tools word the formula a little differently, so compare like with like.
How many days will my stock take to clear?
Days to clear is the number still listed multiplied by the days in the period and divided by the number sold, rounded to a whole day. It assumes the pace of the period carries on, which real sales rarely do. Treat it as a rough guide, not a forecast.
| Sold | Still listed | Period | Sell-through rate | Sales a day | Days to clear |
|---|---|---|---|---|---|
| 30 | 70 | 30 days | 30% | 1 | 70 |
| 12 | 48 | 30 days | 20% | 0.4 | 120 |
| 45 | 105 | 60 days | 30% | 0.75 | 140 |
The first and third rows have the same 30% rate, yet the stock in the third row takes twice as long to clear. A rate alone hides that, which is why the page shows both.
How do I use the rate to decide what to do next?
The page sets no target, because a good figure depends on the item type and your goals. Compare each result with your own earlier periods of the same length. If the rate falls from one month to the next, look at whether your prices have crept above sold listings. A long days-to-clear figure for one product line shows where your money is tied up.
Dividing days to clear by 7 gives weeks of stock: 70 days is 10 weeks. Set that against how long it takes you to find more of the same kind of item. If you would run out in three weeks but need six weeks to source more, start looking now. If the stock would last ten months, buying more of that line only ties up cash.
Is sell-through rate the same as inventory turnover?
No. Sell-through rate counts units for one product or group over a short period. Inventory turnover usually divides the cost of goods sold by average inventory value over a year. Use the cost of goods sold calculator for the figures that turnover needs.
How this tool works and where the numbers come from
Sell-through rate is items sold divided by items sold plus items still listed, for a chosen period. The days to clear stock are the number of listings still active divided by the number sold per day over that period. Both are arithmetic on the numbers you enter.

Frequently asked questions
Where do I find my eBay sell-through rate?
This page does not connect to eBay, so it cannot read your figure. Count the items sold and the active listings for the same period from your own seller reports, enter them, and the page does the arithmetic.
Can sell-through rate be over 100%?
Not here. Items still listed are added to items sold in the base, so the rate runs from 0% to 100%. At 100% nothing is left listed, and at 0% nothing sold.
What is a good sell-through rate?
The calculator gives no benchmark, because the answer depends on the item, the period and the price. Track your own rate month by month and watch the direction.
Why does the length of the period matter?
It sets the sales pace behind the days-to-clear estimate. The same 30 sales over 15 days is twice the pace of 30 sales over 30 days, so the estimate halves. The rate itself does not change.
What if I have nothing listed or nothing sold?
With nothing listed and something sold, the rate is 100%. With nothing sold, the rate is 0% and the page says that days to clear cannot be worked out. With both at zero, the page asks for at least one number.
