About This Calculator
The Sell-Through Rate Calculator helps retailers, e-commerce businesses, and inventory managers measure how quickly their inventory sells. Sell-through rate is one of the most important key performance indicators (KPIs) in inventory management, measuring the percentage of inventory sold within a given period relative to the amount received or purchased.
To calculate the sell-through rate, divide the number of units sold by the number of units received, then multiply by 100 to get a percentage. For example, if you received 1,000 units and sold 650 units during the month, your sell-through rate would be 65%. This metric helps businesses assess product demand, optimize stocking decisions, and identify slow-moving inventory that may require markdowns or promotional efforts.
The calculator also shows the number of unsold units, giving you a complete picture of your inventory position. Use the bar chart or distribution chart to visualize the ratio of sold to unsold inventory at a glance.

What is a good sell-through rate?

Can sell-through rate exceed 100%?
Yes, sell-through rate can exceed 100% if you sell more units than you received in the period. This can happen when you have existing inventory from previous periods. It indicates strong demand and efficient inventory turnover.
What is the difference between sell-through rate and inventory turnover?
Sell-through rate measures the percentage of inventory sold within a specific period relative to what was received. Inventory turnover measures how many times inventory is sold and replaced over a longer period, typically a year. Sell-through is a snapshot metric while turnover is a broader efficiency measure.
How can I improve my sell-through rate?
To improve sell-through rate, you can increase sales through promotions, discounts, and marketing campaigns. Alternatively, reduce the number of units you order from suppliers to better match demand. Better demand forecasting and inventory management also help improve sell-through rates.
What industries use sell-through rate?
