Method and limitations
Baseline expected loss = probability ÷ 100 × impact. Residual probability = probability × (1 − reduction ÷ 100). Residual expected loss = residual probability ÷ 100 × impact. Total with control = residual expected loss + annual control cost. Modelled net benefit = baseline expected loss − total with control.
Assumes a single event that can occur at most once during one year, fixed impact and no severity change from the control. It excludes multiple events, uncertainty ranges, dependencies, discounting, taxes and insurance terms. Control effectiveness is your assumption, not a verified estimate. Currency is a display label; no conversion occurs.
Expected loss is not the maximum loss, a quote, an actuarial model or a recommendation to buy a control. Do not enter confidential or personal information.
