How Retail Markdowns Are Decided: A Simple Guide (2026)

How retail markdowns are decided comes down to a chain of tests, not a hunch on the sale day. A buyer or merchandiser checks how long an item has been on hand, how its sell-through compares with plan, how many selling weeks remain, and how much margin the rest of the assortment can absorb, then sets both a price and a date for that price.

Those tests run thousands of times a week. One example gives a fair sense of the scale: retail technology vendor Markmi described a markdown program for European apparel chain C&A covering roughly 5,000 items across 17 countries, or about 170,000 individual decision points.

The sections below walk through the inputs buyers weigh, the people who make the call, the arithmetic, and the signals a shopper can actually observe. Updated for 2026.

What Does a Retail Markdown Mean?

A markdown is a permanent reduction in the selling price of one specific item, made because that item is not moving at the pace it was expected to move. The original ticket price stays on record, and the lower price becomes the new normal for whatever time remains.

Store conversations blur the word together with sale and clearance, but those are three separate decisions with different triggers and different owners. Getting them straight is the fastest way to understand what a price tag is telling you.

Decision	What it is	Who triggers it	Typical depth	Ends when
Markdown	Permanent reduction of the original retail price on a specific item	Buyer, merchandiser, or planner reviewing aging inventory	Tiered, often from 20 percent down to 50 percent or beyond	The piece is gone
Promotional sale	Planned, calendar-driven price event, often with vendor funding	Marketing and the promotional calendar	Usually shallow and consistent, often 15 to 30 percent	The event window closes
Clearance	Final markdown stage, frequently seasonal or store-wide	Merchant or divisional leader once earlier tiers fail	Deep, sometimes at or below cost	The season ends or floor space is reclaimed
Off-price transfer	Inventory moved to an outlet or third party instead of being marked down	Merchant team after the buying window closes	Not a markdown; a change of channel	The transfer completes

Two related terms show up constantly. A promotion is planned in advance against a date, while a markdown is reactive and item-specific. Clearance is the stage where a brand accepts that the season is over and the job is simply to recover cash and clear space, usually at whatever depth moves the inventory.

How Retail Markdowns Are Decided

The decision combines demand data, inventory age, seasonality, margin position, and store-level results into one answer: reduce now, reduce later, reduce deeply, or leave the price alone. Almost every chain has a written version of this logic, and most also keep a weekly meeting where the exceptions get argued over by hand.

The decision chain, step by step

1. Flag the item. Aging reports surface anything past a set number of weeks in system, usually somewhere between four and twelve depending on the category.
2. Compare sell-through with plan. The planner’s curve for that category shows the expected pace. A big gap below it is the trigger.
3. Count the selling weeks remaining. An item with sixteen weeks of season still to run and 8 percent sold is a different problem from one with four weeks to run and 8 percent sold.
4. Check the inventory position. Inventory-to-sales ratio, the size and color curve, and how many doors still carry it all feed the same decision.
5. Test the cheaper options first. A transfer to another door, a bundle, a vendor markdown agreement, or moving the item into an upcoming promotional window can clear inventory without touching the ticket.
6. Set the depth. Buyers work out the margin they can give up and the unit sales they need in return, then pick a first tier.
7. Set the cadence. The next tier gets a date, usually three to four weeks out, so the first reduction has time to work.
8. Log the reason. Good teams record why an item was marked down. Six months later that log is the only way to tell a buying mistake from a normal season.

Who actually makes the call

The buyer owns the product and the relationship with the vendor, so they carry the first recommendation. The merchandiser owns presentation and can move a style between doors or into an outlet. The planner owns the numbers: sell-through curves, weeks of supply, and whether the category as a whole is carrying too much.

Larger organizations add a pricing analyst, who builds the depth recommendation from elasticity and margin history, and a divisional leader, who signs off on anything past a certain percentage or on a company-wide clearance event. In practice all of it converges in a recurring markdown review, often weekly, where the buyer walks through the flagged list and the planner defends or confirms the plan.

If you are aiming for a role in fashion merchandising, this is the skill to practice. Anyone can learn a pricing rule, but the judgment that makes a markdown defensible is the ability to explain an item’s story in one sentence using sell-through, weeks in system, and remaining life. Candidates who can do that in a presentation tend to move faster, and most entry-level buying roles are judged on exactly that.

What Factors Determine a Product’s Markdown?

Timing and depth come from a set of inputs that rarely move alone. Here are the ones that show up in nearly every markdown decision.

• Sell-through against plan. The single biggest signal. Below the curve means the item is underperforming, no matter how good the product is.
• Weeks in system. How long the item has been available for sale, used as an aging threshold.
• Inventory-to-sales ratio. How many pieces are on hand for each piece selling per week. When this climbs, the overstock is measurable.
• Seasonality and remaining life. Coats in February, swim in September, and holiday goods in January are all past their moment.
• Price elasticity. How much volume responds to a price cut. Elastic items can absorb a deep reduction; inelastic ones need less.
• Role in the assortment. A hero style, a volume driver, a seasonal piece, and a long-tail item each have different markdown rules.
• Margin position. Initial markup and current gross margin set the floor for how deep a reduction can go before the unit loses money.
• Channel and competition. Whether other retailers are running promotions in the same week, and whether the item sits in stores, online, or both.

Trigger	Threshold most teams use	Typical timing	Typical first depth	Decision owner
Sell-through below plan	20 percent or more behind the category curve	Any time, reviewed weekly	20 to 25 percent	Buyer with planner
Aging inventory	Past 8 to 12 weeks in system	Mid-season	20 to 30 percent	Buyer
Seasonal transition	Fixed date set months earlier	Season end	30 to 40 percent	Merchandiser
Broken size or color curve	Core sizes out of stock, fringe sizes heavy	Any time	15 to 20 percent	Buyer
Vendor exit or discontinued line	Confirmed in writing	Immediate	30 percent or more	Divisional leader
Overbought quantity	Inventory-to-sales ratio well above category norm	After the buying window closes	25 to 35 percent	Planner and merchant

How retail markdowns are decided when an item breaks in size

Size curves create their own trigger. If a medium sold out in week two while larges and smalls sit untouched, the item is not really underperforming; it was bought with the wrong shape. Marking down the whole style punishes the sizes that did sell, so buyers usually trim the broken sizes, push the surplus into more doors, and hold the price. That is why the same sweater can be reduced in one store and full price in another.

How Is Sell-Through Used in Markdown Decisions?

Sell-through rate is the share of everything you started with that has actually sold. The formula is short:

Sell-through rate = pieces sold ÷ (pieces sold + pieces on hand) × 100

Suppose a style opened with 420 pieces across the network. After eight weeks, 105 have sold and 315 remain. Sell-through is 105 ÷ 420, or 25 percent. On its own that number means very little; what matters is the distance between it and the curve the planner built for that category.

Category curve at week eight	Actual sell-through at week eight	What the gap means
62 percent	55 percent	Slightly behind. Usually no action yet.
62 percent	38 percent	Behind plan. Review, transfer, or first markdown.
62 percent	25 percent	Well off plan. First markdown is likely this week.
62 percent	11 percent	Season is effectively lost. Move toward clearance or off-price.

Two different curves get compared here, and the distinction matters. The sell-through curve shows what share of the original buy has cleared. The sales curve shows the weekly pace, which is what tells you how fast inventory is actually moving right now. Sellers tend to argue from the sales curve because it looks better this week; planners argue from sell-through because it answers whether the buy worked.

Once the gap is measured, the next question is why it exists. Too many pieces bought, not enough demand, or a delivery that arrived too late into the season each call for a different response. Overbought quantity gets transferred or off-priced, weak demand gets promoted, and a late delivery usually means the item is sold through quickly and never needs a markdown at all.

How Does Inventory Age Affect Pricing Decisions?

Weeks in system is the plainest aging measure, and it is the one most teams use to build a markdown ladder. Schedules that start at 20, 30, 40, 60, and 90 days, with the depth of reduction rising at each step, are common in apparel. The exact numbers shift by category, but the shape is nearly universal: the longer an item sits, the more it gives up.

Age matters because it eats the selling weeks. An item that arrived with twenty weeks of life and has used twelve has half its runway. Reducing early uses the weeks that are left while demand still exists.

Holding inventory is not free either. Cash stays tied up, floor and warehouse space stay occupied, handling labor keeps running, and the item ages. Beyond a certain point the arithmetic changes completely: a piece that sat through two full seasons of storage can be harder to sell than a heavily reduced new arrival, because shoppers assume something is wrong with it.

The seasonal transition is usually the hard deadline. Many US fashion retailers treat January as the point where winter becomes spring on the floor, and mid-summer as the point where summer becomes fall. Whatever cannot be sold by then is repositioned, and that date was set months earlier, usually at line review.

Broken sizes and colors also make an item read as old, even when it arrived last week. Once the core sizes disappear, shoppers assume the style is not selling and skip the rack entirely. That is why good teams watch the size curve as closely as total sell-through.

How Do Buyers Set the Markdown Amount?

The depth comes down to what the item can bear. A buyer looks at the original retail price, the cost per item, the current gross margin, what competitors are charging, and how many pieces the remaining demand can plausibly absorb. Then they work backwards from the target: sell the rest of the inventory in the time left, at a price that still returns something.

Formula	How to calculate it	What it tells you
Markdown dollars	Original retail price minus the new selling price	The unit-level giveaway
Markdown percentage	Markdown dollars divided by the original retail price, times 100	The depth the customer sees
Total dollar markdown	Markdown dollars multiplied by the pieces reduced	The margin given up across the buy
Margin on sell-through (MOS)	Gross margin dollars divided by net sales, times 100	The margin actually earned after discounts
Revenue realization	Actual sales dollars divided by planned full-price sales dollars, times 100	How close the season landed to plan
Weeks to clear	Pieces on hand divided by average weekly sales	How long clearance will take

A worked example

Take a knit sweater with a cost of 38 per piece and an original retail price of 120. The buy was 420 pieces, planned to reach 70 percent sell-through by the end of the season. After eight weeks, 105 had sold, which is 25 percent against a plan of about 62 percent. The gap is large enough to act on.

The first tier takes 20 percent off, so the price moves from 120 to 96. Markdown dollars are 120 minus 96, which is 24 per piece, leaving a gross margin of 58 on each sale. Four weeks later, if sell-through is still short, the second tier takes 35 percent off, moving the price to 78. Markdown dollars are now 42 per piece and the margin has fallen to 40. The final tier, once the seasonal transition arrives, takes 50 percent off and lands at 60, where markdown dollars are 60 and the margin is 22.

Total dollar markdown on the 315 remaining pieces, if they all clear at the final price, is 315 multiplied by 60, or 18,900. Net sales at that point are also 18,900, and margin on sell-through works out to 22 divided by 60, or roughly 37 percent. Holding instead is not free: at a recent pace of about 13 pieces a week, clearing 315 takes close to 24 weeks, and that pace usually slows as the season fades. The buyer is choosing between a real margin now and a storage bill with an uncertain ending.

Research published through the University of Virginia Darden School argues that conventional models are too conservative here. Professor Manel Baucells and colleagues found that cutting prices sooner and deeper than standard modeling suggests can raise profit, with the optimal markdown sometimes landing near twice the conventional recommendation.

Two habits cause most of the damage. The first is waiting so long that the reduction has to be severe to move anything. The second is discounting a hero style that was never going to need it, purely because the season is closing and the report looks tidy that way. Both mistakes usually trace back to the same cause, a buy that never matched the demand.

What Is the Retail Markdown Calendar?

A markdown calendar is the set of fixed dates a retailer commits to in advance, and in most apparel businesses it is built a year ahead during line review. The key dates are the seasonal transitions, the promotional windows, and the final clearance events, and they are chosen so that items get progressively cheaper as the season runs out.

The static version has a real weakness: it assumes the season will unfold the way it did last year. Rain in April, a viral moment in October, a delayed delivery from overseas, any of these break the assumption. That is why more teams now pair the calendar with trigger-based decisions, letting a genuinely underperforming item move early even if the calendar says to hold the price.

Markdown cadence is the part shoppers notice. Tiers typically sit three to four weeks apart so each price has time to work, and retailers usually avoid stacking a markdown inside a planned promotional window, because the same piece discounted twice in a short period trains customers to wait for the next cut.

Software has changed the volume of these calls without replacing the judgment behind them. Optimization tools can simulate thousands of price and timing combinations a day and flag the items most likely to stall, which is why a program handling roughly 170,000 decision points exists as a job at all.

What they cannot do is decide that a knit should leave the assortment entirely, or weigh an off-price offer against keeping the style for another season. People still set the strategy the software runs inside.

How Do Retail Markdowns Differ by Product Type?

Seasonal fashion follows the calendar almost exactly. The reduction schedule is set with the season and rarely bends, so a winter coat gets a long runway and then a fast ladder in January.

Evergreen basics, such as plain tees, leggings, or gold hoops, are managed differently. They sell year round, so a slow week means a distribution problem rather than a seasonal one. Marking down a basic permanently damages the price perception of every other basic, which is why these items get promoted and bundled instead.

Trend-driven products are the opposite problem. When a style works, it sells out in days, and the real markdown decision is about how much more to buy. Trend items that survive past their moment usually have no second chance, so they move to clearance quickly.

Footwear is governed by the size curve. Narrow lasts and hard-to-fit styles create persistent leftover sizes, and the accepted practice is to reduce only the broken sizes rather than the whole style.

Accessories, especially jewelry, carry a different risk. Cutting price on a piece that shoppers consider timeless can push buyers toward a cheaper-looking alternative, so accessories are often protected and reduced late.

Beauty and food products add a clock that fashion does not have. Shelf life and expiry dates turn aging inventory into a hard deadline, and the reduction ladder tightens as that date approaches.

Electronics and furniture follow an end-of-life plan instead. New models set the schedule, and the previous generation moves through manufacturer clearance channels with fixed step reductions.

Can Stores and Online Retailers Markdown Differently?

Yes, at the local level, though most retailers hold national guardrails so the same item does not show two very different prices on the same day. What varies is which store gets the reduction and when.

Local inventory drives most of it. A style sitting in a store with a heavy size curve and weak local traffic may be reduced there while a store ten miles away, where the same style sold cleanly, stays at full price.

Warehouse inventory complicates the picture. An online order is often filled from a distribution center rather than the store the shopper visited, and the two locations can hold very different quantities of the same size. A price shown online may not reflect what any single store has on its floor.

Returns also matter. A store that carries high return rates, or a market where shoppers order several sizes and send most back, is not the same market as one with steady full-price demand. Multi-ship to home programs and marketplace resellers add another layer, since the effective price on a listing can be lower than the retailer’s own.

Regional pricing does happen, usually through separate banners rather than store-level discretion. What is rare is a store manager setting markdown depth alone. That decision normally belongs to the divisional merchant, even when the outcome looks local.

How Can You Tell When an Item Will Be Marked Down?

No signal is reliable, but a few are useful. Treat them as evidence, not a schedule.

• Shrinking size and color selection. Core sizes disappearing while fringe sizes remain is the clearest sign an item is losing momentum.
• The item spreading to more doors. When a style suddenly appears in stores it was never carried in, the extra doors are usually absorbing surplus from an overbuy.
• Repositioning on the floor. Moving to a back corner, a clearance rack, or a table near the fitting rooms usually follows a decision, even if the tag has not changed yet.
• Tag and hardware changes. A different tag style, a smaller security tag, or a switch from a thin tag to a plain hangtag often signals a price event rather than a fitting issue.
• The season turning. A swim suit in the last week of August and a wool coat in early January are past their moment regardless of how popular the style is.
• Consecutive drops. Markdowns usually run in a ladder three to four weeks apart, so a first reduction usually signals a second one is scheduled.

One caution. Shoppers have learned to wait, and that behavior feeds back into the numbers. Threads on r/povertyfinance show people checking markdown racks first and treating the reduced price as the real price, and discussions on r/frugalmefashion focus on whether ticket prices were inflated before sales. The people who set prices can see the same pattern, which is one reason aggressive blanket markdowns get questioned internally as well as online.

To judge whether a reduction is real, compare it against what the item has actually sold for before. Retail documentation defines markdown dollars as original retail price minus new selling price, and a deep second reduction is just that first reduction plus more. An item that has been through two tiers has already conceded far more than its current tag suggests.

Frequently Asked Questions

Conclusion: Start With the Item’s Selling Story

Most price decisions come down to one question: is this item selling at the rate it was bought to sell at, and how many weeks are left to fix it if it is not? Sell-through against plan, weeks in system, the remaining season, and the margin floor decide the timing and depth from there.

Start there before you judge a price. Look at the size curve, count the weeks the item has been available, compare the pace with the season around it, and remember that each tier gives away a little more than the last. Then decide whether waiting buys you something, because sometimes it does.
