About the Warehouse ABC Slotting & Pareto Calculator

The warehouse ABC slotting and Pareto calculator empowers supply chain managers and inventory planners to optimize pick faces and reduce travel time. By categorizing SKUs into A, B, and C classes based on throughput value, you can strategically position fast-moving inventory for maximum fulfillment efficiency.

How it works

  1. Upload or input your SKU list along with annual unit sales and unit cost.
  2. The tool ranks items by total annual usage value to apply the 80/20 Pareto principle.
  3. Review the categorized fast, medium, and slow classes to reassign your racking and bin locations.

Frequently asked questions

Why is the Pareto principle used in warehouse slotting?

The 80/20 rule typically reveals that 20% of your SKUs generate 80% of the movement. These high-velocity items should be placed in the most accessible pick locations.

Should ABC analysis be based on volume or value?

Analyzing by pick frequency optimizes labor and travel time. Analyzing by total dollar value helps prioritize working capital and cycle counting.

How often should a warehouse be re-slotted?

It is best practice to review slotting seasonally or at least semi-annually. Product lifecycles, promotions, and seasonal demand can drastically shift SKU velocity.

What defines a 'C' item in inventory management?

Class C items are typically the bottom 50% of your SKUs that only account for about 5% of total sales volume. They should be stored in higher racks or deeper aisles.
