Formula
The formula for calculating Average Weekly Sell Through is:
Average Weekly Sell Through = Total Units Sold ÷ Number of Weeks
- Total Units Sold: The number of units of a product or SKU sold over a specific period.
- Number of Weeks: The time period (in weeks) over which those sales occurred.
This calculation helps you determine how many units you’re moving on a weekly basis, providing valuable insights into sales velocity.
How to Use
To use the Average Weekly Sell Through Calculator, follow these simple steps:
- Enter Total Units Sold: Input how many units were sold during your selected time frame.
- Enter Number of Weeks: Input the total number of weeks that passed during that period.
- Click “Calculate”: The result will be your average weekly sell-through rate.
You can use this data for one product, a whole category, or even your entire store — just make sure the time period is accurate.
Example
Suppose your store sold 1,200 units of a particular product over 8 weeks.
Using the formula:
Average Weekly Sell Through = 1,200 ÷ 8 = 150 units
Result: You’re selling an average of 150 units per week of that item.
This information can help you schedule restocks, negotiate supplier terms, or even decide if you should increase marketing for that product.
