Sell-through rate: Definition, Formula & Why It Matters
Also called: STR
Sell-through rate is the percentage of available units that sold in a period: units sold divided by units available. It measures demand for a specific product or batch. For online resale, 70% or higher is generally healthy.

Example
Selling 180 of 240 listed units is a 75% sell-through rate.
Why it matters for Reverb sellers
Sell-through is the clearest read on product-market fit at the item level. A low rate means you overbought; a rate near 100% may mean you underpriced or understocked and left money on the table.
