Inventory Shrinkage Percent Calculator












Inventory shrinkage is a common challenge in retail and supply chain management, representing the loss of inventory due to theft, damage, errors, or other factors. Calculating the inventory shrinkage percentage helps businesses measure how much stock has been lost relative to what was available, allowing them to identify issues, reduce losses, and improve profitability.

The Inventory Shrinkage Percent Calculator is a simple yet effective tool designed to calculate the shrinkage rate by comparing the starting inventory plus purchases to the ending inventory over a specific period. This percentage reveals how much inventory was lost and aids businesses in implementing better controls.


Formula

The formula for inventory shrinkage percentage is:

Inventory Shrinkage % = ((Starting Inventory + Purchases - Ending Inventory) / (Starting Inventory + Purchases)) × 100

Where:

  • Starting Inventory is the value of inventory at the beginning of the period.
  • Purchases represent the cost of goods added during the period.
  • Ending Inventory is the value of inventory at the end of the period.

This formula calculates the percentage of inventory lost relative to goods available.


How to Use the Inventory Shrinkage Percent Calculator

To use the calculator:

  1. Enter the dollar value of your starting inventory at the period's start.
  2. Enter the dollar value of your ending inventory at the period's close.
  3. Enter the total dollar amount of purchases made during the period.
  4. Click Calculate to find the inventory shrinkage percentage.

This tool gives you a quick insight into your inventory loss rate.


Example

Assume a store starts with $50,000 worth of inventory, purchases $20,000 more stock, and ends the period with $60,000 worth of inventory.

Calculate:

Goods Available = 50,000 + 20,000 = 70,000
Shrinkage = 70,000 - 60,000 = 10,000

Shrinkage % = (10,000 / 70,000) × 100 = 14.29%

This means the store lost 14.29% of its inventory during the period.
