How to Use This Calculator
  1. Enter Total SKU Count — the number of unique products stored in the warehouse.
  2. Set Fast Movers (A items) % to the share of SKUs that generate the most picks (typically ~20% of SKUs, 80% of picks).
  3. Input Medium Movers (B items) % and Slow Movers (C items) % to complete the velocity distribution.
  4. Enter Total Pick Face Length (ft) — the total linear feet of pick locations available.
  5. Review Hot Zone, Warm Zone, and Cold Zone footage to see how much space each velocity tier receives.
  6. Check Travel Reduction % to estimate how much picker walking time ABC slotting saves versus random placement.

What each input means

Total SKU Count
Total number of unique SKUs stored in the warehouse.
Fast Movers (A items) %
Percentage of SKUs that are fast movers (typically ~20% generating 80% of picks).
Medium Movers (B items) %
Percentage of SKUs with moderate pick frequency.
Slow Movers (C items) %
Percentage of SKUs with infrequent picks — stored furthest from staging.
Total Pick Face Length
Total linear feet of pick face locations available.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Total SKU Count = 1000, Fast Movers (A items) % = 20, Medium Movers (B items) % = 30, Slow Movers (C items) % = 50 = 5 input(s) provided
  2. Calculate Hot Zone
    Hot Zone
    150 = 150
  3. Calculate Warm Zone
    Warm Zone
    175 = 175
  4. Calculate Cold Zone
    Cold Zone
    175 = 175
