Risk impact calculator
Score a risk's impact across five domains, combine it with likelihood, and get a risk priority number and tier — the same triage logic used to sort a risk register.
Impact by domain — 1 (negligible) to 5 (catastrophic)

Risk priority number (impact × likelihood, 1–25) is a prioritization heuristic, not a probabilistic forecast. Use it to rank risks against each other and decide what needs attention first.
