Probability of Claim Impact Calculator

Calculate probability of claim impact using single loss expectancy (SLE) and annual loss expectancy (ALE) based on asset value, exposure factor, and annual rate of occurrence.

Input your information

Formula

Single Loss Expectancy (SLE) = Asset Value × (Exposure Factor / 100). The expected financial loss from a single incident if the risk materializes.

Annual Loss Expectancy (ALE) = SLE × (Annual Rate of Occurrence / 100). The expected annual financial loss, incorporating both impact (SLE) and probability (ARO).

Risk Score = (ALE / Asset Value) × 100. The annual expected loss as a percentage of asset value. Higher scores indicate higher risk relative to asset value.

Exposure Factor = Percentage of asset value that would be lost if risk materializes (0-100%). For example, 5% exposure factor means 5% of asset value would be lost.

Annual Rate of Occurrence (ARO) = Probability of event occurring in a year, expressed as percentage (0-100%). For example, 10% ARO means 10% chance (0.1 probability) of occurrence per year.

SLE and ALE are fundamental risk assessment metrics. SLE quantifies impact, while ALE quantifies expected annual loss. Use ALE to compare to insurance premiums and evaluate risk mitigation cost-effectiveness.

Steps

  • Enter asset value (total value of asset at risk).
  • Enter exposure factor (percentage of asset value that would be lost if risk materializes).
  • Enter annual rate of occurrence (probability of event occurring in a year, as percentage).
  • Review single loss expectancy, annual loss expectancy, and risk assessment.

Overview: Risk Assessment Metrics

Probability of claim impact assessment uses quantitative metrics to evaluate financial risk. Single Loss Expectancy (SLE) and Annual Loss Expectancy (ALE) are fundamental risk assessment tools.

Key Metrics

  • Single Loss Expectancy (SLE): Expected financial loss from a single incident
  • Annual Loss Expectancy (ALE): Expected annual financial loss, incorporating impact and probability
  • Risk Score: Annual expected loss as percentage of asset value

Single Loss Expectancy (SLE)

SLE Formula

Single Loss Expectancy is calculated as: SLE = Asset Value × Exposure Factor

Example Calculation

If an asset worth $100,000 has a 5% exposure factor:

  • SLE = $100,000 × 5% = $5,000

This means the expected loss from a single incident is $5,000.


Annual Loss Expectancy (ALE)

ALE Formula

Annual Loss Expectancy is calculated as: ALE = SLE × Annual Rate of Occurrence (ARO)

Example Calculation

If SLE is $5,000 and ARO is 10% (0.1 probability per year):

  • ALE = $5,000 × 0.1 = $500

This suggests an expected annual loss of $500 due to the risk.


Application to Insurance

Insurance Decision Making

Use ALE to evaluate insurance cost-effectiveness. If ALE is $500/year, consider insurance with premiums under $500/year if coverage provides adequate protection. Compare ALE to insurance premiums and deductibles.

Risk Mitigation

Risk mitigation can reduce exposure factor or ARO, lowering ALE. Compare mitigation costs to ALE reduction. If mitigation costs $200/year and reduces ALE by $400/year, mitigation is cost-effective.


Conclusion

Probability of claim impact assessment uses SLE and ALE to quantify financial risk. SLE measures impact, while ALE measures expected annual loss. Use ALE to compare to insurance premiums and evaluate risk mitigation cost-effectiveness. Higher risk scores require attention and may justify insurance or mitigation measures.

FAQs

What is single loss expectancy (SLE)?

Single loss expectancy (SLE) is the expected financial loss from a single incident. Formula: SLE = Asset Value × Exposure Factor. It represents the monetary impact if the risk materializes once.

What is annual loss expectancy (ALE)?

Annual loss expectancy (ALE) is the expected annual financial loss from a risk. Formula: ALE = SLE × Annual Rate of Occurrence (ARO). It incorporates both the impact (SLE) and probability (ARO) of the risk.

What is exposure factor?

Exposure factor is the percentage of asset value that would be lost if the risk materializes. For example, if a $100,000 asset has 5% exposure factor, $5,000 would be lost. Exposure factor ranges from 0% to 100%.

What is annual rate of occurrence (ARO)?

Annual rate of occurrence (ARO) is the estimated frequency of the event occurring within a year, expressed as a percentage. For example, 10% ARO means a 10% chance (0.1 probability) of occurrence in a year.

How is risk score calculated?

Risk score is calculated as: Risk Score = (ALE / Asset Value) × 100. It represents the annual expected loss as a percentage of asset value. Higher risk scores indicate higher risk relative to asset value.

What is a high risk score?

Risk scores above 5% are considered high, indicating significant expected annual losses relative to asset value. Risk scores above 10% are very high and may require immediate risk mitigation measures.

How do I use this for insurance decisions?

Use ALE to determine appropriate insurance coverage limits and premiums. If ALE is $500/year, consider insurance with premiums under $500/year if the coverage provides adequate protection. Compare ALE to insurance costs.

What about risk mitigation?

Risk mitigation can reduce exposure factor or ARO, lowering ALE. For example, security measures may reduce theft probability (ARO), while backups may reduce data loss impact (exposure factor). Compare mitigation costs to ALE reduction.

How accurate are these estimates?

Estimates are based on assumptions about asset value, exposure factor, and ARO. Accuracy depends on data quality and risk assessment expertise. Review and update estimates regularly as conditions change.

What about multiple risks?

For multiple risks, calculate ALE for each risk separately and sum them for total expected annual loss. Consider correlation between risks: if risks are correlated, total ALE may be higher than the sum of individual ALEs.
