Markdown Optimization
Markdown optimization times, sizes and targets price reductions to clear residual inventory while limiting the total margin given up to get it done.
Markdown optimization in apparel planning encompasses two related but distinct practices: (1) structuring pre-season plans to minimize markdown necessity, and (2) optimizing the timing, depth, and targeting of markdowns that do occur to maximize sell-through with the least possible margin sacrifice.
The most effective markdown optimization happens before the season starts — through accurate buy depth, size curve precision, and allocation to full-price sell-through doors. Reactive markdown management — deciding when and how much to discount — operates on a smaller margin opportunity than preventive planning.
Sources of markdown in apparel
Markdowns in apparel are almost always traceable to specific planning decisions made before the season:
Overbuying: Total units purchased exceed what the style would sell at full price within the sell window. Every over-bought unit eventually requires a price reduction to clear.
Wrong size distribution: Units bought in size ratios that don't match demand leave specific sizes as residuals. A style that sells through in aggregate may still generate significant markdown exposure on the sizes that ran long.
Wrong door allocation: Inventory sent to doors that don't sell the style at full price will eventually clear via markdown — even if other doors would have sold it at full price.
Late delivery: A style that delivers after the peak sell window has a compressed full-price period. The same buy depth that would have sold at full price early in the season requires markdown support if delivery is late.
Reducing markdown through better pre-season planning
The most impactful markdown optimization decisions are made before a single unit is bought:
- Setting depth targets based on realistic demand signals, not last season's buy quantities
- Applying size curves built from actual sell-through, not category averages
- Allocating to doors with demonstrated full-price sell-through for the style category
- Building planned markdowns into the MFP at realistic levels — not optimistic assumptions
Planned markdown % is a key input in the Merchandise Financial Plan. Brands that plan markdowns at 15% when historical performance is 25% are building a financial plan on an incorrect assumption — and will discover the gap at end of season.
In-season markdown management
When markdowns do occur, optimization focuses on:
Timing: Earlier markdowns on slow-moving styles free OTB for reorder on faster sellers — but reduce per-unit margin. The trade-off depends on the sell window remaining.
Depth: Incremental markdowns (15% → 25% → 40%) test price sensitivity before committing to the deepest discount needed.
Targeting: Markdowns don't need to be sitewide or chainwide. Targeting underperforming doors or slower-selling sizes reduces the margin cost of clearance.
