Free tool / FMEA
RPN calculator
Multiply severity, occurrence and detection scores. Compare the result with thresholds defined by your team.
How to use the result
RPN = severity × occurrence × detection. The range is 1–1,000 on a 10-point scale, or 1–125 on a 5-point scale. A high detection score means the failure is harder to detect.
Agree the scoring definitions before comparing results. A low total does not make a severe consequence acceptable. Your qualified reviewers decide the actions and record the reasoning.
Does this establish compliance?
No. This tool performs arithmetic and applies your selected bands. It does not implement an approved risk procedure, the AIAG/VDA Action Priority tables, or a validated system.
