Markdown cost calculation overview

The markdown cost calculation model is a sophisticated real-time optimization component within Sterling Intelligent Promising that helps minimize revenue loss when fulfilling online orders. Reliance on steep reactive discounts is reduced, the markdown spiral is prevented, and overall profitability is optimized.

Business context

Markdowns are a key pricing lever that help to optimize inventory turnover and drive sales. Regular markdown refers to a planned reduction in the selling price of a product, typically done to clear inventory, respond to seasonality, or stimulate demand. However, without proper planning and optimization, businesses can fall into a markdown spiral where excessive discounting erodes margins and devalues brand perception. For more information about markdown data, see Frequently asked questions (FAQ) about Sterling Intelligent Promising.

The Markdown cost calculation feature addresses this challenge by incorporating future markdown considerations into real-time fulfillment decisions, enabling a more strategic approach to inventory allocation.

How it works

Real-time decision making

When an online order is received, the markdown cost calculation model evaluates each possible SKU-node-quantity combination by comparing two distinct scenarios:

  • Immediate fulfillment: Assigning inventory to the current order at the current online price.
  • Future sales: Holding inventory for potential future sales at reduced markdown prices.

Key calculation factors

The model considers several critical data points to calculate the potential revenue difference:

  • Tiered markdown levels: Multiple markdown dates and corresponding price reductions across the product lifecycle.
  • Predicted velocity: Forecasted sales rate based on historical data and demand patterns.
  • Current inventory levels: Real-time stock availability at each fulfillment node.
  • Online price versus markdown prices: Revenue comparison between current and future discounted prices.
  • Time Horizons: Duration until each markdown event occurs.

Markdown cost formula

The markdown cost represents the potential revenue loss (or gain) from fulfilling an order now versus later. The calculation compares:

Markdown cost = (Revenue from immediate sale) - (Expected revenue from future sale at markdown price)

A positive markdown cost indicates that fulfilling the order now is more valuable than holding inventory for future markdown sales. A negative markdown cost suggests that the inventory might generate more revenue if held for future sales, even at a discounted price.

Integration with total cost optimization

The calculated markdown cost is not evaluated in isolation. Instead, it becomes one component of a comprehensive total cost calculation that includes:

  • Shipping costs: Transportation expenses from fulfillment node to customer.
  • Load balancing costs: Penalties for uneven inventory distribution across nodes.
  • Stockout costs: Risk and impact of running out of inventory at specific locations.
  • Markdown costs: Potential revenue loss from future price reductions.

The optimizer weighs all these factors together to select the best fulfillment strategy that minimizes total cost while meeting customer demand and service level commitments.

Tiered markdown strategy

Defining markdown levels

Fulfillment managers can define multiple markdown tiers across a product's lifecycle:

  • Initial price: Full retail price of $100 at product launch.
  • First markdown: Modest reduction, for example, $85 after initial selling period.
  • Second markdown: Moderate reduction, for example, $60 as the season progresses.
  • Final markdown: Aggressive clearance pricing, for example, $40 to eliminate remaining inventory.

Business benefits

1. Reduced reliance on reactive discounts

By incorporating markdown planning into fulfillment decisions, the system helps prevent situations where excessive inventory accumulation forces steep, unplanned discounts. The proactive approach enables controlled, strategic price reductions.

2. Prevention of markdown spiral

The markdown spiral occurs when aggressive discounting trains customers to wait for sales, leading to reduced full-price sales, which in turn requires even deeper discounts. The markdown cost calculation model helps break this cycle by:

  • Optimizing inventory allocation to minimize markdown exposure.
  • Balancing immediate sales against future markdown risk.
  • Supporting planned, tiered markdown strategies instead of reactive fire sales.

3. Improved inventory health

By considering markdown implications in fulfillment decisions, the system naturally promotes:

  • Better inventory distribution across fulfillment nodes.
  • Reduced aging inventory that requires aggressive discounting.
  • More balanced stock levels that support full-price sales.

Use cases

Seasonal products

For seasonal merchandise, the model helps:

  • Fulfill orders from locations with excess seasonal inventory.
  • Preserve inventory at locations where full-price sales are still strong.
  • Time markdowns as the season progresses.

Fashion and apparel

In fast-fashion environments, the system enables:

  • Strategic allocation of trendy items during peak demand.
  • Controlled markdown progression as styles age.
  • Prevention of excessive end-of-season clearances.

Electronics and technology

For products with predictable obsolescence patterns:

  • Optimize fulfillment before planned price reductions.
  • Balance current sales against anticipated markdown events.
  • Minimize losses from technology refresh cycles.

Configuration and setup

Markdown schedule definition

Fulfillment managers configure markdown schedules by specifying:

  • Markdown dates: Markdown dates: When each price reduction takes effect.
  • Markdown prices: The reduced price at each tier.
  • Applicable products: SKUs or product categories subject to the markdown plan.
  • Location scope: Location scope: Which fulfillment nodes participate in markdown planning.

Velocity forecasting

The system requires demand forecasting inputs to predict:

  • Expected sales rate at current price.
  • Anticipated sales rate at each markdown price level.
  • Seasonal or promotional demand variations.

Integration points

The markdown cost calculation integrates with:

  • Pricing systems: To receive current and planned markdown prices.
  • Demand forecasting: To obtain velocity predictions.
  • Inventory management: For real-time stock level data.
  • Order management: To trigger calculations for each order.
  • Reporting systems: To track markdown optimization performance.

Monitoring and reporting

Real-time metrics

The system provides visibility into:

  • Markdown cost impact on fulfillment decisions.
  • Frequency of markdown-influenced routing.
  • Inventory aging and markdown exposure by location.

Benefits report

The Benefits report specifically tracks markdown optimization outcomes:

  • Markdown avoidance value: Revenue protected by strategic fulfillment.
  • Average markdown percentage: Comparison of planned versus actual discounts.
  • Markdown timing accuracy: How well execution aligns with planned schedule.
  • Total cost savings: Combined benefit of all optimization factors including markdown.

Performance analysis

Managers can analyze:

  • Which products benefit most from markdown-aware fulfillment.
  • Which locations consistently require markdown intervention.
  • Seasonal patterns in markdown cost impact.
  • ROI of markdown planning initiatives.

Best practices

  • Plan markdown tiers in advance: Define clear, tiered markdown schedules at the beginning of each season or product lifecycle. Avoid ad hoc discounting that undermines the optimization model.
  • Align forecasts with reality: Regularly update velocity forecasts to reflect actual demand patterns. Accurate predictions are essential for effective markdown cost calculations.
  • Balance multiple objectives: Markdown cost is one factor among many. The optimizer considers total cost, so low markdown costs should not override critical service level or shipping cost considerations.
  • Monitor and adjust Use the Benefits report to continuously evaluate markdown strategy effectiveness. Adjust markdown schedules, timing, or depth based on performance data.
  • Coordinate across teams: Ensure alignment between merchandising who plans markdowns, fulfillment who runs orders, and finance who measures outcomes. The markdown cost calculation model works best when all teams understand and support the strategy.

Summary

The markdown cost calculation model represents a significant advancement in intelligent fulfillment optimization. By incorporating future pricing considerations into real-time order routing decisions, Sterling Intelligent Promising helps businesses to maintain better margins, incorporate more strategic markdown plans, and avoid the destructive markdown spiral. The result is a more profitable, sustainable approach to inventory management and pricing that benefits both the business and its customers.
