Free FMEA tool
Free FMEA Action Priority Calculator
Enter Severity, Occurrence and Detection ratings to calculate deterministic Action Priority and RPN. No account is needed to calculate or export a PDF.
Action Priority calculation
Action Priority is calculated by the server from the current ratings; RPN is shown for comparison only.

What this FMEA Action Priority calculator does
This free calculator evaluates one failure scenario at a time. Enter Severity, Occurrence and Detection, then select Calculate to receive an Action Priority and the legacy RPN. It is designed for a practical first decision, not as a substitute for a complete multi-row FMEA.
Severity, Occurrence and Detection
Severity describes the consequence if the failure reaches the customer or process. Occurrence estimates how often the cause is expected. Detection reflects the ability of current controls to detect the issue. Use Qhubio’s FMEA rating guides to anchor each rating consistently.
How FMEA Action Priority differs from RPN
RPN multiplies Severity × Occurrence × Detection. Action Priority is a decision logic: it deliberately gives seriousness and detection context more weight than a single multiplication result. Similar RPN values can therefore lead to different Action Priorities.
Worked-use example and limitations
For a torque-control concern, enter ratings supported by process evidence, calculate the result and use it to decide whether action is needed. Do not treat a calculator result as a public decision table, a replacement for engineering judgement or a complete FMEA record.
Frequently asked questions
How is FMEA Action Priority calculated?
Qhubio evaluates the three ratings with deterministic server-side Action Priority logic. Action Priority is not an RPN threshold.
Is this FMEA Action Priority calculator free?
Yes. Calculation and PDF export are free. An account is only required to save and reopen a calculation.
Do I need a full FMEA?
Use a full FMEA when you need to compare multiple failure modes, document causes and controls, assign actions and maintain the analysis over time.
