Sell-through rate is the share of a retailer's stock that sold to shoppers over a stated period: units sold ÷ units received (or available) × 100. The time window and the denominator change the number more than anything else, so always say which ones you used. This article covers retail and wholesale sell-through, the number a store tracks on your line. It is not eBay or reseller sell-through, which is sold ÷ active listings.

Here is an illustration, not a target: a boutique receives 120 units of a style and sells 84 of them in the window. Sell-through is 84 ÷ 120 = 70%. If the store also had units on hand at the start of that window and you count them, the denominator gets bigger and the rate goes down, even though the same 84 units sold. For related terms such as open-to-buy and MAP, see the wholesale terms glossary.

Key takeaways

• Sell-through = units sold ÷ units received or available over a stated period × 100. Always name the period and the denominator.
• Retailers track unit, full-price, dollar and weekly sell-through. Each one answers a different question.
• No published benchmark tells you what a good sell-through rate is. Compare like windows and ask each key account what it targets.
• Sell-in is what you ship to the store. Sell-through is what the store sells to shoppers. Reorders depend on the second.
• The data comes from the retailer: direct requests, EDI 852 reports, vendor portals or a Shopify report filtered by vendor.

Which sell-through number are you looking at?

There are four common versions. When a buyer quotes a sell-through rate, find out which one they mean before you compare it with anything.

The denominator varies too. Common choices are:

1. Units received in the period.
2. Stock on hand at the start of the period plus receipts. Wall Street Prep uses beginning stock on hand in its version.
3. Units sold plus ending inventory.

Problems start when you compare one account's number with another's and the two were built on different denominators.

How do you calculate sell-through rate in Excel?

Put units sold in one column and the denominator in the next. Then use one of these formulas in Excel or Google Sheets and format the result cell as a percentage:

• Units received: =Sold/Received
• Sold plus ending inventory: =Sold/(Sold+Ending_inventory)
• Beginning on hand plus receipts: =Sold/(Beginning_on_hand+Receipts)

For full-price sell-through, replace total units sold with units sold at full price. For dollar sell-through, use sales dollars over the value of stock available.

What's a good sell-through rate for wholesale?

It depends on four things:

• Category. A basic or core item and a trend-driven seasonal item sell at different speeds.
• Price point. Higher-priced items usually take longer to move.
• Full-price or total. A high rate that relied on markdowns tells you something different from the same rate at full price.
• Time window. A rate measured after the first few weeks can't be compared with one measured at season end.

You'll find "good sell-through" ranges online. Most come from software vendors, not audited studies, so use them carefully. Comparisons you control are more useful: the same style last season, the same window at the same account, or how your line did against the store's other lines if the buyer will share that. The simplest step is to ask each key account what it targets.

What's the difference between sell-in and sell-through?

Sell-in is what the brand ships to the store, meaning your wholesale orders. Sell-through is what the store sells to its shoppers. The two can diverge. A large sell-in looks good on your order report, but if sell-through is weak, the store is left holding your stock. Practitioners on r/fashionwholesale say stores left with unsold stock at season end are less likely to reorder. Sell-in drives this season's revenue, and sell-through decides whether you get next season's order.

How does a wholesale brand get sell-through data from retailers?

Sell-through comes from the retailer's point-of-sale and inventory systems, so you have to ask for it or get access to it. Common routes:

• Ask key accounts directly. Keep the request polite and specific, for example: "How did style X sell in its first 4 to 8 weeks?"
• EDI 852 reports and vendor portals. Larger retailers may share sales and inventory data through EDI 852 product activity reports or vendor portals. Inventory Insights notes that not every retailer does this. Department store buyers often look at results by door, which is covered in how to sell to department stores.
• Shopify reports. A boutique that runs Shopify has a product sell-through rate report and can filter it by vendor, which makes the request easy for them.
• Reorders as a proxy. If an account reorders a style early, that style is selling.

What should you do with sell-through numbers?

Use them to plan the next order with each account:

1. Reorder winners. Styles that sell through quickly at full price are the ones to replenish or offer in new colors.
2. Offer swaps on slow styles. Practitioners on r/fashionwholesale say brands that help stores sell through, with options such as swaps or lower opening minimums, earn reorders.
3. Adjust the next buy and assortment. Move depth toward proven styles and sizes for that store.
4. Plan with the buyer's budget in mind. Buyers use sell-through to reforecast open-to-buy, so strong numbers on your line can free up budget for your next order.

Over time, sell-through by style and account lets you set opening minimums and order sizes from evidence instead of guesses. The guide to starting to sell wholesale covers how to set minimums.

What can a brand see on the sell-in side?

Brandboom, wholesale ordering software for fashion and lifestyle brands, shows the sell-in side. Its order reports include Top Products (top sellers by total sales or quantity for a date range), Production (quantities per style, option and size) and Spending (each customer's spending). The Analytics dashboard shows Top Products and Top Buyers with period comparison. Buyer Maps show which stores bought now versus before, by area. That makes it easy to spot accounts that stopped ordering and are worth a sell-through conversation. Buyer activity tracking shows who viewed a line sheet, what they clicked, and any abandoned or draft carts. Brandboom plans start at $50/month for the Basic plan.

FAQ

What does sell-through rate tell you?

Sell-through rate shows how quickly shoppers bought the stock a store received over a set period. For a wholesale brand, it shows which styles are earning their space on the floor, which ones may need markdowns or swaps, and how likely an account is to reorder. Full-price sell-through also shows whether those sales depended on discounts.

Is sell-through the same as inventory turnover?

No. Sell-through is the percentage of available units sold within a specific window, and it's usually tracked by style or by delivery. Inventory turnover measures how many times a business sells and replaces its inventory over a longer period, often a year. Both measure how fast stock moves, but sell-through is the number buyers use for style-level and reorder decisions.

How often should I ask accounts for sell-through?

Ask after a style's first weeks on the floor, for example 4 to 8 weeks, and again before you plan the next season's order. Keep each request narrow and name the styles and the window. For accounts that share EDI 852 reports or vendor portal access, check the data on a regular schedule so you don't need to email the buyer.

Is eBay sell-through the same thing?

No. eBay and reseller sell-through usually means items sold divided by active listings, and it's used to judge demand for a product category on that marketplace. Retail and wholesale sell-through measures units a store sold against units it received or had available. The names match, but the inputs and the decisions they support are different.
