Frequently Asked Questions

What is sell-through rate?
Sell-through rate is the percentage of inventory sold during a specific period. It's calculated by dividing the number of units sold by the number of units available (beginning inventory plus any new stock) and multiplying by 100.
How do I calculate sell-through rate?
Use the formula: (Units Sold / Units Available) × 100. For example, if you had 100 units available and sold 40, your sell-through rate is 40%. The calculator also shows units remaining (units available minus units sold).
What is a good sell-through rate?
A good sell-through rate varies by industry, but generally 80% or higher is considered excellent, while below 40% may indicate overstocking or slow sales. Use the calculator to track your performance over time.

Tips & Common Mistakes

Tips

  • Ensure you input the total units available, including beginning inventory and any new stock received during the period.
  • Use consistent time periods (e.g., monthly, quarterly) for accurate comparisons.
  • Track sell-through rate regularly to identify trends and adjust pricing or promotions.
  • Combine sell-through rate with other metrics like inventory turnover for a fuller picture.

Common Mistakes to Avoid

  • Forgetting to include new inventory received during the period in the 'units available' field.
  • Using the number of units sold instead of units available in the denominator, which inflates the rate.
  • Comparing sell-through rates across different time periods without adjusting for seasonality.
