Formula
ALE = AV·EF·likelihood + recovery·likelihood; residual = ALE·(1 - control effectiveness)Quantitative risk model for patch delay. Primary output: Residual Risk.
Variables
- Asset value ($) — the asset value input used in the calculation.
- Exposure factor (%) — the exposure factor input used in the calculation.
- Annual likelihood (%) — the annual likelihood input used in the calculation.
- Control effectiveness (%) — the control effectiveness input used in the calculation.
- Expected recovery cost ($) — the expected recovery cost input used in the calculation.
- Annual control cost ($) — the annual control cost input used in the calculation.
- Insurance coverage ($) — the insurance coverage input used in the calculation.
Step-by-Step Calculation
- Collect your inputs. Gather the values for: Asset value, Exposure factor, Annual likelihood, Control effectiveness, Expected recovery cost, Annual control cost, Insurance coverage.
- Enter the values into the calculator above. Each field accepts numeric values.
- Apply the formula
ALE = AV·EF·likelihood + recovery·likelihood; residual = ALE·(1 - control effectiveness)to combine your inputs. - Read the result displayed in the Result panel. In this case, the single loss expectancy is shown in the appropriate unit.
- Interpret the value in the context of your task — see the interpretation section above.
