Reliability Toolkit

Exponential Reliability, MTBF and FIT Calculator

Evaluate a constant-hazard exponential reliability model and convert between MTBF, hourly hazard rate and failures-in-time (FIT).

Engineering inputs

Supported range: 0 to 1e+09.

Supported range: 1e-06 to 1e+12.

Results

Your calculation

Enter the inputs and select Calculate.

Model notes

Constant-hazard exponential model. FIT is failures per billion device-hours; early-life and wear-out behaviour are not represented.
