Sell-Through Rate Calculator
From units sold and units received, compute the sell-through rate: units sold ÷ units received × 100, the share of stock sold in a period.

At a glance:The sell-through rate shows how much stock sold. Sell-through rate = units sold ÷ units received × 100. A higher rate means faster movement and healthier demand; a low rate points to overstock.
Formula
Sell-through rate = units sold ÷ units received × 100.
$$\text{Sell-through Rate} = \dfrac{\text{Units Sold}}{\text{Units Received}} \times 100\%$$How to Use
- Enter the units sold.
- Enter the units received (available to sell).
- Read the sell-through rate.
FAQ
What sell-through rate is good?
It depends heavily on category, period and pricing — there is no absolute standard. A common retail reference: for a one-month window, about 80% or above usually means strong, healthy turnover; clearly below half may signal slow-moving stock needing a pricing or selection review. But always read it with the period — the same 80% reached in one week is a hot seller, in three months merely average. Fix the period when comparing, and benchmark against similar items and the same period last year; trends beat a single number.
Is a very high sell-through rate always good?
Not necessarily. A high rate means the item is popular, but if it is caused by ordering too little, it is bad news — stock sells out fast and you miss sales and profit, and customers may go to competitors. The ideal is a high rate with enough stock to meet demand and timely replenishment. So treat near-100% or early sell-outs as a 'reorder' signal, not just a celebration.
How is sell-through rate different from inventory turnover?
Both measure sales efficiency but from different angles. Sell-through looks at a specific batch over a specific period — what share of that batch sold — good for a single item or a specific purchase, usually over short cycles (weekly, monthly). Inventory turnover measures how many times the whole inventory is sold and replenished over a period (usually a year). Simply: sell-through sees 'what percent of this batch sold'; turnover sees 'how many times the whole stock turns a year'. Retailers use both: sell-through for short-term reorder/clearance, turnover for long-term capital efficiency.
How do I combine sell-through, inventory turnover and aging to manage stock?
These three are the 'three brothers' of retail stock management, each from a different angle; using them together avoids misreading a single metric. Sell-through looks at 'what percent of a batch sold in a period' — the front-line short-term gauge for reorder/clearance. Inventory turnover looks at 'how many times the whole inventory sold and restocked in a year' (COGS ÷ average inventory) — the capital-efficiency gauge for the whole business. Aging (aging inventory) looks at 'how long each item has sat' — splitting stock by days held to flag dead stock. Use three layers: first, inventory turnover as a health check of the whole business vs peers and your history; if it falls, stock is building up. Second, sell-through to diagnose item by item — find high-rate (reorder) and low-rate (promote or stop) items. Third, aging to locate the problem — for low sell-through items, see how long they have sat; items past a threshold need decisive clearance. Turnover tells you 'is the whole healthy', sell-through tells you 'which items', aging tells you 'how urgent'. Pair with our Inventory Turnover Calculator.
How do I improve a low sell-through rate, and does discounting to clear stock lose money?
Low sell-through means stock is stuck, tying up cash and warehousing and risking seasonal devaluation. Improving it has three routes, and discounting is only one. First, pricing: if too high, moderate cuts or promotions (discounts, BOGO, bundles) can lift demand — but discount with strategy (see below). Second, exposure and display: sometimes the item is fine but poorly placed or has a weak listing; better merchandising, photos and ads can raise sell-through without cutting price. Third, source control: low sell-through is often caused by over- or wrong-buying — buying by historical sell-through data avoids the problem at the root. On 'does discounting lose money': it depends on whether the discounted price stays above the item's variable cost (mainly the purchase cost). For already-bought, stuck stock, the purchase cost is sunk; leaving it only accrues storage and capital cost and may devalue to nothing. So clearing even at a loss (below original cost) can still becut losses if it recovers cash and frees space for better sellers — but limit discounts to timed, quantified clearance sales to avoid training customers to wait for sales, and don't rush to dump items that could sell next season. Diagnose the cause first (price? exposure? selection?), then act; pair with our Margin and Conversion Rate calculators to set the discount floor.
