What the number means
Sell-through rate measures demand relative to competition — something a raw sold count can't. A high rate means most of what gets listed actually sells, so there's room for you. For the full breakdown of what counts as a good rate and how to use it, read eBay sell-through rate explained.
Sell-through rate FAQ
How do you calculate sell-through rate?
Sell-through rate = (sold listings ÷ total listings) × 100. For example, 300 sold out of 500 total listings is a 60% sell-through rate. Measure both over the same time window — a rolling 30 days works well on eBay.
What is a good sell-through rate on eBay?
As a rough guide: under 40% is oversupplied, 40–60% is workable, 60–100% is healthy, and over 100% (items selling faster than they're listed) signals strong, under-served demand.
