Markdown
A reduction in a product's selling price to clear stock — planned at end of season or reactive in-season — and the single biggest controllable drain on realised margin.
By Oana Bradulet
Markdown is a permanent reduction in a product's selling price, taken to clear stock that isn't selling fast enough at full price. It's the lever every consumer brand reaches for when a buy comes in heavier than demand — and it's usually the largest controllable hit to realised margin across a season.
Markdown is permanent, which is what separates it from a promotion. A promotion is a temporary price cut you reverse afterwards; a markdown is a reset — the line trades at the new price until it's gone. The two are often run together, but they behave differently on the P&L.
Planned versus reactive markdown
There are two fundamentally different reasons to mark down, and conflating them hides where the money goes.
- Planned (end-of-season) markdown. Built into the plan from the start. Seasonal ranges are expected to end on markdown — you buy knowing a percentage of the range will clear at reduced price, and you budget the margin cost up front. This is healthy and normal; the question is only how deep and how late.
- Reactive (in-season) markdown. Unplanned. A line is selling below its rate of sale target, cover is building, and you cut price mid-season to rescue the cash before the window closes. This is the markdown that hurts, because it wasn't in the plan and it's eating margin you'd counted as banked.
A season's markdown spend is the sum of both. Brands that only budget the planned half get a nasty surprise when the reactive half lands on top.
Markdown depth and the margin cost
Markdown depth is how far you cut — 20% off, 40% off, 70% off. The depth determines both the demand uplift and the margin you give away, and the two don't move together.
The cost is brutal at the margin line. If a line was bought at 60% intake margin and you take 50% off the selling price, you don't lose 50% of your margin — you can wipe it out entirely, because the price cut comes straight off the gross profit, not the cost. A few points of markdown can turn a profitable line into a loss-maker faster than most operators expect.
This is why markdown is measured as a percentage of sales — markdown rate — and tracked against a season budget. A fashion brand running 25% of sales through markdown is in a very different position from one running 40%, even if both hit their top-line revenue.
Earlier is cheaper
The most important principle in markdown management: a shallow cut taken early almost always costs less margin than a deep cut taken late.
The reason is stock. Early in the window you're marking down a smaller residual at a smaller depth, while demand is still live. Leave it, and two things compound — the unsold quantity grows, and the remaining demand shrinks as the season ages. By the end you're discounting a large pile at a deep cut into a thin market. The total margin foregone is far higher.
- Mark down 15% in week 4 on a line that's tracking 20% behind, and you might pull it back onto plan with a modest margin hit.
- Wait until week 10, and you're taking 50% off a much bigger residual to clear it before it becomes dead stock — and dead stock that never clears at all is a 100% margin loss plus the holding cost.
The discipline is acting on the leading signal — a slowing rate of sale and building cover — rather than waiting for the calendar to force your hand.
Markdown, sell-through, and the next buy
Markdown doesn't sit on its own. It's the corrective to a buy that was too heavy or a forecast that was too optimistic, and the feedback should flow back into buying.
- A line that needed deep reactive markdown was over-bought; its sell-through rate at full price was below plan.
- Persistent markdown across a sub-category is a ranging signal — too many options, or the wrong ones.
- The clean version of the loop: full-price sell-through informs next season's buy quantity, so the markdown shrinks because the buy was right, not because the discounting was clever.
Common pitfalls
- Budgeting only planned markdown. Reactive in-season markdown lands on top; a season budget that ignores it always overshoots.
- Marking down too late. A shallow early cut beats a deep late one on total margin almost every time, because the residual and the remaining demand both move against you with time.
- Confusing markdown with promotion. Markdown is a permanent price reset; a promotion is temporary. They hit margin differently and shouldn't share a line in the plan.
- Ignoring the feedback to buying. Heavy markdown is a signal the buy was wrong. If that doesn't change next season's quantity, you'll mark down again.
Common mistakes
- →Budgeting only planned end-of-season markdown. Reactive in-season markdown lands on top, so a budget that ignores it always overshoots.
- →Marking down too late. A shallow early cut beats a deep late one on total margin, because both the residual stock and the remaining demand move against you over time.
- →Treating markdown and promotion as the same thing. Markdown is a permanent price reset; a promotion is temporary and reversed afterwards.
- →Failing to feed markdown back into buying. Heavy markdown signals the buy was too heavy; if next season's quantity doesn't change, the markdown repeats.
