Risk Matrix
Classify risks by likelihood and impact.

Engineering Assumptions
Preliminary decision support
- The risk score bands (low/medium/high/severe) are entirely user-defined per their own project risk register or company methodology; the tool assumes no universal classification.
- All percentages and inputs are user-defined; the calculation is purely arithmetic and assumes no particular code or specification.
- A preliminary decision-support estimate: the result does not replace an approved design calculation or review by a competent authority.
Formula Summary
- risk score = likelihood × impact
- exposure = cost impact × probability%
- residual risk = exposure × (1 − mitigation effectiveness%)
- band = user-defined score bands
Results
Enter your data and press Calculate to see the results.
Engineering Insight
This tool calculates the risk score, the expected financial exposure and the residual risk after mitigation, placed within the user's own bands.
Recommended Action
Add this risk to the project risk register with an owner and a next review date.
