MTTR calculator

Mean time to repair from total repair time and number of repairs.

Calculating…

How it's calculated

MTTR = total repair time ÷ number of repairs

Decide what the clock includes and stay consistent. Most sites measure from breakdown to the asset being handed back to production, which includes response, diagnosis, parts, repair and testing.

Breaking MTTR into those stages usually shows the biggest win is not the repair itself but waiting: for an engineer, for parts or for information.
