MTTR Calculator
What is MTTR?
Mean Time to Repair (MTTR) is a key performance metric used in maintenance and reliability contexts to measure the average time required to repair a system or component after a failure occurs. MTTR is calculated by dividing the total downtime by the number of failures within a given period. This metric helps organizations understand and improve their maintenance processes by identifying how long it typically takes to restore operations after a malfunction. Reducing MTTR can lead to increased system availability and productivity.
What Is the formula to calculate MTTR?
The formula for calculating Mean Time to Repair (MTTR) is:
Where:
- Total Downtime is the cumulative amount of time the system or component is non-operational due to failures, measured in hours, minutes, or any consistent time unit.
- Number of Failures is the total count of failures that occurred within the measurement period.
The result gives the average time taken to repair the system or component and return it to operational status.
