Mean Time To Failure Calculator

The Mean Time to Failure (MTTF) Calculator is a tool used to estimate the average time until a system or component fails. It is commonly used in reliability engineering to assess the expected reliability of a product or system.


The formula for calculating MTTF depends on the failure rate (λ) of the component or system and is given by:

MTTF = 1 / λ

where λ is the failure rate, typically expressed in failures per unit of time.


Let’s say you have a component with a failure rate of 0.01 failures per hour. By using the formula, the MTTF would be calculated as 1 / 0.01 = 100 hours. This means that, on average, the component is expected to fail once every 100 hours of operation.
