What is Failure Rate?

Failure Rate is a measure of how often a system or component fails over a specified period. It is a crucial metric in reliability engineering, maintenance, and quality control, used to predict the reliability and performance of products and systems.

How to Calculate Failure Rate?

The formula to calculate Failure Rate is:

Where:

• Number of Failures is the total number of times the system or component has failed during the observed period.
• Total Operating Time is the cumulative time that the system or component has been operational.

The resulting failure rate is typically expressed in failures per hour. This metric helps organizations understand the reliability of their systems and identify areas for improvement in their maintenance practices.
