Tool
Sell-through rate
units sold ÷ units received × 100%
“What % of the stock I brought in sold through?” — snapshot per SKU/period.
You are here
Inventory turnover
COGS ÷ average inventory
“How many times does my inventory turn over in a year?” — period & cost based.
Enter multiple products to see the sell-through ranking and flag slow-mover (below 50%).

Reorder planner
Set a sell-through target — the tool calculates how many units must sell to hit the target.
Real examples
Clothing store: 150 of 200 units sold
A store received 200 pcs of shirts for the new season and sold 150 pcs.
Weighted average = 392 ÷ 550 × 100 = 71,27% (healthy). Slow-mover: Kemeja Flanel — candidate for discount/bundling or smaller reorder.
Reorder planner: kejar target 80%
Stock of 250 units, 150 sold so far. Sell-through target 80%.
Need to sell = 80% × 250 = 200 units → still short 50 unit.
Asumsi: “unit diterima” vs “beginning inventory”
Units received in this tool = total units that reached your hands during the measurement period: beginning-of-period stock + plus all purchases/goods receipts during that period.
If you did not receive new goods during the period, then “units received” = beginning stock (beginning inventory) — the formula stays valid.
For eBay/marketplace sellers or secondhand goods: enter the number of units you listed/stocked at the start of the measurement period.
Built-in validation: units received cannot be zero, and units sold cannot exceed units received.
Frequently asked questions
What is sell-through rate?
Sell-through rate is the percentage of units successfully sold out of the total units you received/brought in during a period. The formula: (units sold ÷ units received) × 100%. Example: receiving 200 units and selling 150 units = 150 ÷ 200 × 100% = 75%. This metric is a core inventory KPI in retail for assessing how well a product or category sells.
What is the difference between sell-through rate and inventory turnover?
Both measure inventory efficiency but from different angles. Sell-through rate = units sold ÷ units received × 100%: a snapshot of “what % of incoming goods sold through”, ideal for per-SKU or per-receipt-batch evaluation. Inventory turnover = COGS ÷ average inventory: measures how many times all inventory turns over in one period (e.g. a year), based on cost and time. A product can have high sell-through for one batch but low annual turnover if rarely reordered. To calculate turnover, use the Inventory Turnover Calculator.
What sell-through rate is considered good?
As a general guide (not an official industry standard): above 80% is generally excellent, 50–80% is generally healthy, and below 50% deserves review (consider discounts, bundling, or smaller reorders). Real benchmarks vary widely by category — fast fashion, furniture, and electronics have different expectations — and are also influenced by season and business model. Always compare against your own store history.
Should I use “units received” or “beginning inventory”?
This tool uses “units received”: beginning-of-period stock plus all units that came in during the period. If no new goods were received, it equals beginning inventory so the formula stays valid. For eBay or marketplace sellers, enter the number of units listed at the start of the measurement period. What matters is consistency: compare periods using the same definition.
How does the reorder planner work?
You enter current units sold, units received, and target sell-through. The tool calculates the total units that must sell (target × units received), then the gap vs what has sold — rounded up because units cannot be fractional. Example: an 80% target on 250 units = 200 units must sell; if only 150 have sold, you still need 50 more units.
When should I use sell-through rate vs GMROI?
Use sell-through rate when your question is “how well is this item selling” — purely about how fast stock clears. Use GMROI when your question is “how profitable is my inventory investment” — GMROI includes margin (gross margin ÷ average inventory cost), so a fast-selling thin-margin product can lose to a moderate-selling thick-margin product. For margin analysis, use the GMROI Calculator.
Are this calculator’s results professional advice?
No. This tool calculates illustrative business metrics to help with inventory planning — not professional financial advice. Stock purchasing, pricing, and discount decisions must still consider your business context and, if needed, be discussed with a professional.
