fail rate

Malfunction occurrence proportion

Fail rate is the frequency at which something fails, expressed as a percentage or ratio.

In manufacturing, it measures defective units: The factory reduced its fail rate to under two percent.

In education, it tracks students who don't pass: The course has a thirty percent fail rate.

Engineers use fail rate to assess reliability of components over time.
