Cyber Risk ALE Calculator

Estimate Annualized Loss Expectancy for a specific cyber exposure using your own figures.
The estimated total liability if this data or system were fully compromised — breach notification, remediation, regulatory fines, and lost business.
25%
The percentage of asset value likely lost in a single incident of this type. Ransomware on a partial dataset is often 15–35%; a full database exfiltration can run higher.
0.15
How often this type of incident is expected per year. 0.15 means roughly once every 6–7 years; 1.0 means expected annually.
Single Loss Expectancy (SLE) $2,000,000
Annualized Loss Expectancy (ALE) $300,000 / year
This calculator is an educational tool for illustrating the SLE × ARO = ALE method. It does not constitute a risk assessment, insurance recommendation, or financial advice. Compare your ALE result against actual insurance premiums or control costs before making a decision, and consult a qualified risk professional for a formal assessment. Sector benchmark figures reference the IBM Cost of a Data Breach Report 2026.
