Use the result with context

Results are estimates for planning and education. Confirm rates, taxes, fees, and legal requirements with the relevant institution or a qualified professional before making a financial decision.

Formula and method

Divide units sold by units received and multiply by 100. Keep the product scope and period consistent, especially when opening stock or returns affect availability.

Sell-through (%) = units sold ÷ units received × 100

Worked example

Enter these known values and leave the other values blank.

Number of units sold

Number of units received

Sell-through rate

Assumptions and limitations

  • Inputs describe one consistent reporting period. Review the formula and counting conventions before comparing results.

Common questions

Can I compare products with different launch dates?

Only with care. Different selling windows and replenishment patterns can make the percentages misleading; align the period and inventory convention first.
