Sell-Through Rate Calculator — Inventory Performance
Enter units sold and units received to instantly get your sell-through rate — the key retail metric for inventory performance. Add unit cost and sale price to also see revenue, cost of goods, and gross profit.

How does this calculator work?
Sell-Through Rate = (Units Sold ÷ Units Received) × 100%. Enter units sold and the starting inventory to get the percentage sold, remaining stock, and — if you add price and cost — revenue, COGS, and gross profit for the period.
Formula
How this is calculated
Sell-through rate measures what fraction of the inventory that entered a location (or that was on hand at the start of a period) was actually sold during that period. A 100% rate means everything sold; 0% means nothing moved. Retailers typically aim for 80% or above as a sign of healthy demand, while below 50% may signal overstock or weak demand.
The formula is simple: divide units sold by units received (or beginning-of-period stock) and multiply by 100. The complementary metric — the remaining stock percentage — tells you how much was left unsold. When you also enter cost per unit and sale price, the calculator computes total revenue (units sold × price), cost of goods sold (units received × cost), and gross profit (revenue minus COGS), along with the residual value of unsold stock.
Sell-through rate is typically measured weekly or monthly and varies by product category and season. A high rate does not always mean maximum profit — stockouts lose sales too. Pair it with days-of-supply or inventory turnover for a fuller picture.
Frequently asked questions
Most retailers consider 80% or above good for a given period, but the benchmark varies by category. Perishables and fashion items need very high rates (>90%) to avoid markdowns; durable goods can sustain lower rates. Compare against your category average and prior periods.
Sell-through rate is a percentage (sold ÷ received) for a fixed period. Inventory turnover is COGS ÷ average inventory — an annualised ratio that tells you how many times the stock cycled. Both measure velocity; sell-through is simpler and needs no average-inventory figure.
Options include promotions or markdowns to stimulate demand, reducing future purchase orders for slow movers, bundling slow products with fast sellers, or improving placement and marketing. Persistent low rates often signal a product–market mismatch rather than a temporary issue.
