Sell-through rate is the share of the units you received that sold within a set period: units sold divided by units received, times 100. Receive 200 jackets, sell 120 of them in the first eight weeks, and your eight-week sell-through is 60%. Published benchmarks for apparel mostly land between about 60% and 85%, but the number only means something next to its time window. Sixty percent after two weeks is a hit. Sixty percent at the end of the season is a markdown problem.
Sell-through rate calculator
Put in units received and units sold. Add full-price units and the number of weeks if you have them, and the calculator also gives you full-price sell-through, how much of the selling happened on markdown, and how many weeks of stock you have left at the current pace.
The calculator runs in your browser. Nothing you type is sent anywhere.
How do you calculate sell-through rate?
Divide units sold by units received for the same period, then multiply by 100. If you are measuring stock that was already on hand when the period started, add that beginning inventory to the units received.
With opening stock: units sold / (beginning on hand + units received) x 100
Worked example. A denim brand receives 600 units of one jean style on March 1 and sells 390 by April 26, eight weeks later. 390 / 600 x 100 = 65%. That's an eight-week sell-through of 65%, with 210 units left. At 48.75 units a week, those 210 units last about 4.3 more weeks.
The five versions you will run into
Sell-through is one idea measured several ways. Check which one a buyer, a report or a benchmark is using before you compare numbers.
| Version | Formula | What it tells you |
|---|---|---|
| Unit sell-through | Units sold / units received x 100 | How fast product moves. The default, and what the calculator above uses. |
| Full-price sell-through | Units sold at full price / units received x 100 | How much sold before any markdown. The truest read on whether the buy was right. |
| Dollar sell-through | Net sales at retail / (opening stock + receipts) at retail x 100 | Catches markdown damage that unit sell-through hides. Retailers often plan in dollars. |
| Weekly sell-through | Units sold this week / units on hand at the start of the week x 100 | The early signal. A falling weekly rate warns you before the season total does. |
| Retailer sell-through (wholesale) | Units the retailer sold to shoppers / units you shipped to the retailer x 100 | Whether your wholesale stock is moving off their floor. Needs the retailer's sales data. |
Unit and dollar sell-through can tell different stories. Sell 80% of the units but half of them at 40% off, and the units look great while the dollars don't. That's why full-price sell-through sits next to the headline number in the calculator.
What is a good sell-through rate for apparel?
For an in-season read, published apparel benchmarks mostly fall between about 60% and 85%. Fast fashion aims for 80% or more, luxury sits closer to 50%, and seasonal categories like swim are judged on where they finish the season. Below 50% is where most sources say a style needs action.
| Category | Published target | Warning sign | Source |
|---|---|---|---|
| Apparel and fashion | 65 to 85% | Under 65% needs review, under 40% critical | Toolio, 2026 |
| Apparel (wholesale) | 80% or more | Under 60% | RepSpark, 2024 |
| Fashion, typical range | 60 to 80% | Under 50% | Heuritech, 2025 |
| Fast fashion | 80% or more | Heuritech, 2025 | |
| Luxury | Around 50% | Heuritech, 2025 | |
| Luxury and jewelry | 50 to 65% | Toolio, 2026 | |
| Footwear | 75 to 85% | Under 60% | RepSpark, 2024 |
| Golf and resort | 70 to 85% | Under 55% | RepSpark, 2024 |
| Outdoor and performance | 65 to 80% | Under 50% | RepSpark, 2024 |
| Swim and surf | 80 to 90% by season end | Under 65% | RepSpark, 2024 |
| Health and beauty | 75 to 90% | Toolio, 2026 | |
| Home goods and furniture | 55 to 75% | Toolio, 2026 |
These ranges come from software companies that work with retailers and brands, not from audited industry studies, and they don't fully agree. RepSpark's apparel target starts at 80%; Heuritech's typical range tops out there. Use them as a sanity check, then set your own targets by category and by week.
Why the time window changes the answer
The same style can post very different numbers depending on when you measure. Shopify's published figures make the point: fragrance at around 23% after eight weeks and 63% after a year, cosmetics at about 25% after eight weeks and 48% after 52 weeks. Neither is a failure. They're just slower categories than fashion.
Shopify also separates short-life product from core. Seasonal and launch product should clear 80% inside its launch window, while evergreen styles can run at 40 to 60% a month or a quarter as long as turns and margin hold. For fashion, the useful checkpoint is six to eight weeks after the delivery lands, which is where our consumer brand KPI guide puts it: late enough to trust, early enough to chase, hold or mark down.
Sell-through vs sell-in, sell-out, turnover and weeks of supply
Sell-in is what you shipped to the store. Sell-through is how much of it the store sold. A brand can have a record sell-in season and a weak sell-through season, and the second one shows up next season as smaller reorders, markdown requests and returns.
| Metric | What it measures | How to calculate it |
|---|---|---|
| Sell-in | Units a brand ships to a retailer | Units shipped in the period |
| Sell-through | Share of available units that sold | Units sold / units received x 100 |
| Sell-out | Units the retailer sold to shoppers | Retail units sold in the period, from POS or EDI 852 data |
| Inventory turnover | How many times inventory sells and is replaced in a year | Cost of goods sold / average inventory at cost |
| Weeks of supply | How long current stock lasts at today's pace | Units on hand / average units sold per week |
| Stock-to-sales ratio | Inventory carried for each dollar of sales | Beginning-of-month inventory at retail / sales for the month |
Sell-through works style by style and week by week. Turnover is a finance number for the whole inventory over a year. Weeks of supply is the forward-looking one: it tells you when a door runs dry. Most buyers look at sell-through and weeks of supply together, because a style with 70% sell-through and two weeks of supply left is a reorder, not a success story to file away.
How do wholesale brands get sell-through data from retailers?
You can't calculate a retailer's sell-through from your own shipments. You need that retailer's sales and on-hand numbers, and there are four common ways to get them.
- EDI 852 product activity data. The retailer sends units sold and units on hand, often store by store, usually weekly. It's the cleanest source when you can get it. Our EDI 852 guide covers the quantity codes and store detail.
- Retailer supplier portals. Many large retailers publish sales and inventory to their vendors through their own portal. Walmart's Retail Link is the best-known example.
- Buyer reports and rep counts. Smaller accounts often share a spreadsheet, or your reps count stock on the floor. RepSpark also points to reorder patterns on B2B platforms as a proxy.
- Consignment and shop-in-shop reports. On consignment, the store tells you what sold, and that report is what you invoice from. The sell-through math is the same; the data just arrives on their schedule.
What should you do when sell-through is low, or too high?
Before you mark down a slow style, find out whether it's slow or just in the wrong place. A markdown fixes weak demand. It does nothing for good product sitting in the wrong doors or the wrong sizes.
When it's low
- Check store-level numbers first. Three doors sold out and twelve still full is a transfer, not a markdown.
- Check the size run. The middle sizes can sell out while the ends sit, and the style looks slow overall.
- Compare against the same week last season, not a season-end number.
- Then act: move stock, promote it, bundle it or mark it down. And don't reorder it.
When it's very high
- Above about 90% early in the season often means you ran short, not that the buy was perfect. Toolio flags this range as a reason to check for missed sales.
- Reorder faster, or chase the style while there's still selling time.
- Look at which sizes and colors went first, and buy deeper there next season.
Does low sell-through cause EDI chargebacks?
No. Retailer chargebacks come from compliance misses: a late or wrong ASN, carton label errors, routing guide violations. Low sell-through shows up in other ways, such as smaller reorders, requests for markdown support or returns, depending on what you agreed with that retailer. If you're fighting deductions, that's a chargeback management problem, not a sell-through one.
How do you track sell-through in AIMS360?
AIMS360 holds the numbers sell-through is built from, by style, color and size: what you received, what you shipped, what was on hand on any date, and, for retailers that send it, their EDI 852 sales and on-hand data. For a standing sell-through chart that refreshes on its own, that data goes into Power BI or a Live Excel workbook.
Hot List
Your top-selling styles by units sold or by how many customers bought them, by style or by style and color, for any date range.
Cut and Sold report
Stock, work in process, open orders and total units shipped for each style and color, with size detail and a date range. See style analysis reports.
Stock as of a date
On-hand inventory as it stood on the day you choose, which is the starting number for any sell-through window.
EDI 852 import
Retailer sold and on-hand quantities matched to your own style, color and size records, with store-level detail kept when the retailer sends it.
Power BI and Live Excel
Sell-through by style, color and size as a standing chart on live data. See Power BI and AIMS360 reporting.
Consignment stock
Consigned goods can sit in their own virtual warehouse, so you see what's still out on consignment and invoice units as the store reports them sold.
What no system does on its own: see a retailer's shelf. Sell-through at an account is only as good as the data that account sends. If a retailer doesn't send an 852 or give you portal access, you're working from their reports or your reps' counts, whatever software you run.
Sell-through rate questions
Sell-through rate is the percentage of available units that sold in a period: units sold divided by units received, plus any opening stock, times 100. It's the standard measure of how fast a style, color or size is moving.
Published ranges for apparel mostly fall between about 60% and 85% for an in-season read. Fast fashion targets 80% or more and luxury sits closer to 50%. Always compare against a time window, because the same number means different things at week two and at the end of the season.
Divide the units sold at full price by the units received and multiply by 100. If 200 units arrive and 95 sell before any markdown, full-price sell-through is 47.5%, even if total sell-through ends the season at 60%.
Sell-in is what a brand ships to a retailer. Sell-through is how much of that stock the retailer sold to shoppers. Strong sell-in with weak sell-through usually leads to smaller reorders, markdown requests or returns the next season.
Sell-through is a percentage for a set period, usually read style by style. Inventory turnover is how many times the whole inventory sells and is replaced in a year: cost of goods sold divided by average inventory at cost. Sell-through tells you which styles are working. Turnover tells finance how hard the inventory dollars are working.
Weekly for the first few weeks after a delivery lands, with a formal read at six to eight weeks and a final number at the end of the season. The six to eight week read is usually the last point where a chase, hold or markdown decision still changes the outcome.
Yes. A style that sells out in its first few weeks probably lost sales it could have made. Very high early sell-through is a signal to reorder faster, check the size curve and buy deeper next time.
Divide units on hand by the average units sold per week. With 210 units left and about 49 selling each week, you have roughly 4.3 weeks of supply.
Through EDI 852 product activity data, retailer supplier portals, sales reports from buyers and rep store counts. Without one of these, a brand only knows what it shipped, not what sold.
No. Chargebacks come from compliance problems such as a late or incorrect ASN, carton label errors or routing guide violations. Low sell-through usually shows up as smaller reorders, requests for markdown support or returns, depending on the agreement with the retailer.
