Sell-through rate is the share of inventory you sold in a period compared to what you received. It is one of the cleanest signals of how fast a product moves and whether you ordered the right amount. The formula is simple: units sold divided by units received, times 100. The calculator above runs that math instantly and adds units remaining plus an estimated time to sell out at your current pace.
The formula is units sold divided by units received, multiplied by 100. Say you received 200 units of a product at the start of the month and sold 120 of them by month end. Divide 120 by 200 to get 0.6, then multiply by 100 for a 60% sell-through rate. The 80 units left over are your remaining inventory, and at 4 units sold per day you have roughly 20 days of stock before you sell out.
One detail trips people up: use beginning inventory for the period, not your current on-hand count. Sell-through measures what you moved against what you started with, so if you received more stock mid-period, track it as a fresh cycle. Measuring the same window you receive and replenish on keeps the number honest and comparable month to month.
A good rate varies by category, so treat any single benchmark with care. Many retailers use roughly 80% in a period as a strong target, but fast-moving consumables and seasonal promotions can run far higher, while durable goods, furniture and high-ticket items often sit lower and still perform well. The useful question is not whether you hit one number, but whether the rate is climbing, holding or slipping against your own history.
Read the extremes for what they signal. A very low rate usually points to overstock or weak demand, which ties up cash and risks markdowns later. A very high rate near total clearance can mean you understocked and left sales on the table, since shoppers who found an out-of-stock product simply bought elsewhere. The sweet spot is selling most of your inventory while still meeting demand.
Three levers move sell-through. First, pricing: targeted promotions, bundles and markdowns clear slow stock without training shoppers to wait for discounts on everything. Second, demand forecasting: ordering quantities that match real demand keeps you from drowning in overstock or running dry. Third, and the one most retailers underuse, is driving more qualified traffic to the product itself.
That last lever is where SEO earns its keep. Ranking your product and category pages for the terms shoppers actually search pulls in steady, intent-rich demand that compounds without paying per click. More of the right visitors landing on a page lifts its sell-through directly.
