Inventory Shrinkage Rate Calculator

Calculate inventory shrinkage

Inventory shrinkage is the loss of stock between what the records say you should have and what you actually count, caused by theft, damage, spoilage, administrative error and supplier fraud. The shrinkage rate is calculated by subtracting the actual counted inventory value from the recorded value, dividing by the recorded value, and multiplying by one hundred. Recorded inventory of two hundred thousand against an actual count of one hundred ninety-four thousand is a shrinkage of six thousand, or three percent. The calculator can also express shrinkage as a percentage of sales, the more common retail benchmark.

Measuring shrinkage against both inventory and sales gives two useful perspectives on the loss.

Controlling shrinkage

Shrinkage directly reduces profit because the lost goods were paid for but never sold, so controlling it is a priority for retailers and warehouses. Industry shrinkage as a share of sales typically runs around one to two percent, and figures well above that warrant investigation into theft, process failures or record-keeping errors. Regular physical counts compared against records are the only way to measure it accurately.

Reducing shrinkage usually involves a mix of security, staff training, tighter receiving and inventory processes, and better technology. Tracking the rate over time shows whether these measures are working. All calculation happens locally in your browser.
