How to use it

  1. Enter opening stock, units received in the period and units sold.
  2. The result appears straight away and updates as you edit.
  3. Copy the result, or copy a link that keeps the same values to share it.

How it is calculated

Sell-through rate = units sold ÷ (opening stock + units received) × 100.

Example

Inputs: Opening stock = 0 units, Units received in the period = 400 units, Units sold = 260 units. Result: Sell-through rate: 65%; Units left: 140 units; Total available to sell: 400 units.

Limits and caveats

  • It only compares units available with units sold and does not reflect timing within the season.
  • Some stores measure it by value instead of units; you can enter values in the same fields.

Questions about this tool

What is a good sell-through rate?

It depends on the category and period, but many retailers see 40% to 80% a month as healthy.

How is it different from turnover?

Sell-through is the share sold of what was available in one period, while turnover counts how often stock is replaced over a longer span.

What should I do with a low seller?

Review price and display, consider a discount or bundle, and order less of it next time.
