What is sell-through rate?
Also: STR · Sell-through
Sell-through rate (STR) is the percentage of listed inventory that actually sells within a set period — sold items divided by total listed, times 100. It measures how quickly stock moves and how well you're sourcing demand. A high STR means healthy turnover; a low STR signals a growing death pile of stale, unsold listings.
How it's used in a listing
A reseller who says “my sell-through is about 20% a month” means roughly a fifth of their listed items sell every month.
How it maps to the grade scale
Sell-through rate isn't a condition grade, but condition affects it: accurately graded, honestly described items sell faster and get fewer returns, lifting STR. Overgrading inflates prices and stalls listings, dragging sell-through down.
