Markdown Optimization
Markdown optimization is the practice of timing, sizing, and targeting price reductions to maximize sell-through on residual inventory while minimizing the total margin impact — by reducing the depth, duration, and necessity of markdowns through better pre-season planning.
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.
