The sell-through rate is a term used in retail to measure how many units are sold out of stock. The sell-through rate doesn’t refer to the number of sales made by a product, but rather the percentage of products that have been sold after being put on sale. It’s important for retailers to track this metric because it can help them determine whether or not they should increase their inventory levels or take more action with promotions and discounts to drive more customers into stores.

The sell-through rate is the percentage of products that have been sold over a period of time. The sell-through rate is calculated by dividing the number of products sold by the total number of products in stock at a given point in time.

Similarly, the sell through percentage is calculated as follows:

\text {Sell Through Percent} = \frac {\text {Product Sales}} {\text {Products Recieved}} \times 100

The term “sell-through” can also refer to an index value that represents how much inventory has been sold out of all available inventory; it’s often used to assess whether or not a company needs more product on hand. To calculate this type of index value, simply find each company’s average monthly inventory balances for each month by adding together its ending inventory balance from each month and dividing by 12 (for example). Then take this average monthly inventory balance and multiply it by its actual annual sales revenue from last year; finally, add those two figures together and divide them by 52 weeks in order to get an estimate of how much money was spent on unsold goods throughout last year.


The sell-through rate is a measure of how much inventory of a product is sold in a given period of time. It’s calculated by dividing the amount of inventory sold by the total starting inventory. This number can be expressed as a percentage or as a decimal. For instance, if you start with 1,000 widgets and sell 500, then your sell-through rate is .5 (or 50 percent). The Sell-through rate is also called sell-through percentage, sell-through index, or sell-through ratio.

Sell through rate can be used to determine whether or not you’re making money on your sales strategy. If you have an item that has been sitting on your shelf for over six months but hasn’t yet been purchased by anyone (and therefore isn’t counted as part of its total sales), it may mean that people aren’t interested in buying this particular item anymore and will stop purchasing it after they’ve already bought one—so why not just get rid of it?

It can be used to:

  • Determine profitable sales strategies. The sell-through rate is an important indicator of how well a product is selling—and what strategies might be most effective to boost sales. You can use the sell-through rate calculator to determine whether a particular pricing strategy or marketing approach would be successful in increasing your overall sales. You may also want to consider changing your product packaging, packaging design or price point if the calculated sell-through rate doesn’t match up with what you were hoping for.
  • Determine market interest for similar products over historical time periods (i.e., quarters). Many businesses use historical data when making business decisions related to their current inventory levels and forecasting future demand as they prepare budgets and forecasts for upcoming periods (e.g., quarterly). The sell-through rate calculator helps them do this by showing whether there have been any shifts in interest levels that indicate shoppers will be more interested at some point in the future than they’ve been historically—or vice versa!


The sell-through rate is used in various industries, such as fashion and retail, to determine profitable sales strategies. When you’re shopping for an item that isn’t engaging a lot of interest from the market, you might be able to purchase it at a deep discount or get additional discounts on related items. In this case, gather data regarding the market interest for similar products over historical time periods to determine whether there are any shifts in interest levels that indicate that shoppers will be more interested at some point in the future.

A company’s supply chain can also be affected by using a sell-through rate calculator because it helps identify which products have been selling well and which haven’t been selling as well as expected so companies can adjust accordingly based on this information. This can help ensure that products aren’t sitting around unsold too long before they’re sold out completely or returned due to expiration dates passing while they were still sitting unsold on shelves or racks.


What is a good sell-through rate?

It varies by industry and organization, but the general rule is that a sell-through rate above 80% is ideal.

How is the sell-through rate calculated?

The sell-through rate is calculated by dividing the number of units sold by the number of units received, then multiplying the sum by 100.

Why is the sell-through rate important?

The sell-through rate is important because it allows you to monitor the efficiency of your supply chain.
