## About Failure Rate Calculator (Formula)

The Failure Rate Calculator is a tool that uses the Failure Rate Formula to calculate the frequency of failure of a system or component.

Failure rate is typically measured in units of failures per hour, and is used in reliability engineering, maintenance planning, and other fields.

The failure rate formula is based on the total number of failures and total time.

The formula is

**fr=TF/TT**

where fr is the Failure Rate, TF is the Total Number of Failures and TT is the Total Time. By inputting the values for these factors into the calculator, the user can quickly and easily determine the Failure Rate,

which can be useful for assessing the reliability of a system or component, for maintenance planning, and for making decisions about when to replace or repair a system.
