# Business Impact Quantification Calculator

- **PURPOSE:** Provides a structured method for estimating and communicating the potential business costs of security incidents in financial terms that resonate with executives.
- **WHEN TO USE:**When preparing risk assessments, security budget justifications, or board presentations about cybersecurity risks.

## PART 1: SCENARIO DEFINITION

**Security Risk Scenario**[e.g., Customer Data Breach affecting 50,000 records]

**Vulnerable Asset**[e.g., Customer Database]

**Threat Vector**[e.g., SQL Injection]

**Affected Business Functions**[e.g., E-Commerce, Customer Service]

   Credit Monitoring Services: $\_\_\_\_\_\_\_\_ ($\_\_\_\_\_ per affected individual × \_\_\_\_\_ individuals × \_\_\_\_\_ years)

   Call Center Operations: $\_\_\_\_\_\_\_\_ ($\_\_\_\_\_ per day × \_\_\_\_\_ days)

   Subtotal B: $\_\_\_\_\_\_\_\_

### C. Legal & Regulatory Costs

   Productivity Loss: $\_\_\_\_\_\_\_\_ ($\_\_\_\_\_ average hourly cost × \_\_\_\_\_ employees × \_\_\_\_\_ hours)

   Third-party Contract Penalties: $\_\_\_\_\_\_\_\_

   Subtotal D: $\_\_\_\_\_\_\_\_

### E. Reputational Damage

   Customer Churn: $\_\_\_\_\_\_\_\_ (\_\_\_\_\_ customers × $\_\_\_\_\_ customer lifetime value × \_\_\_\_\_% attrition rate)

   Brand Value Impact: $\_\_\_\_\_\_\_\_

   Subtotal E: $\_\_\_\_\_\_\_\_

### F. Long-term Impact

   Insurance Premium Increase: $\_\_\_\_\_\_\_\_ per year × \_\_\_\_\_ years

   Credit Rating/Borrowing Cost Impact: $\_\_\_\_\_\_\_\_

   Subtotal F: $\_\_\_\_\_\_\_\_

## PART 4: TOTAL IMPACT SUMMARY

Total Direct Costs (A+B+C): $\_\_\_\_\_\_\_\_

Total Indirect Costs (D+E+F): $\_\_\_\_\_\_\_\_

TOTAL ESTIMATED IMPACT: $\_\_\_\_\_\_\_\_

Confidence Level in Estimate: □ Low □ Medium □ High

## PART 5: PREVENTION/MITIGATION ANALYSIS

Proposed Security Investment: $\_\_\_\_\_\_\_\_

Estimated Risk Reduction: \_\_\_\_\_% 

Return on Security Investment: \_\_\_\_\_× (Total Impact × Risk Reduction ÷ Security Investment)

## IMPLEMENTATION TIPS: 

- Start with direct costs where data is more readily available, then progressively add indirect costs as your estimation capabilities mature
- Use industry benchmark reports and past incidents at similar organizations to inform your estimates
- Document your assumptions clearly to build credibility with business stakeholders
