Inventory turns measure how many times your MRO inventory is issued and replaced over a year.
How fast is your storeroom moving? Enter annual consumption value and average on-hand inventory value to get your turns ratio, days of supply, and benchmark context for your industry.
It is how many times your stocked spare parts are issued and replenished in a year, calculated as total issue value divided by average inventory value.
Divide total issue value over the period by average inventory value over the same period.
COGS is a retail and manufacturing formula. MRO storerooms issue parts to work orders rather than selling them, so issue value is the correct numerator.
Lower than retail. Many MRO storerooms run 1 to 3 turns, and critical and insurance spares pull the number down by design, so judge against your own mix.
