Calculates a risk score from Likelihood × Severity, classifies it against a standard risk-level banding, and shows exactly where it falls on a visual risk matrix.

A Note on Matrix Design
This tool uses a simple, symmetric Likelihood × Severity product with quartile-based bands, since it's a widely understood default. Many real organizational risk matrices are asymmetric — deliberately weighting severity more heavily than likelihood, so a rare-but-catastrophic event (e.g., Likelihood 1 × Severity 5) is treated as higher risk than a frequent-but-trivial one (Likelihood 5 × Severity 1), even though the arithmetic product is identical. If your organization has an approved risk matrix with specific cell-by-cell risk levels, use that as the definitive reference — this calculator is a general-purpose default, not a substitute for your documented risk assessment procedure.
