Business Cyber Liability Insurance Cost Estimator

Estimate your annual cyber liability insurance premium based on your business profile, industry risk factors, data handling practices, and security controls.

Annual Revenue ($)

Your business's total annual gross revenue.

Industry Risk Category

-- Select Industry -- Low Risk – Retail / Wholesale (non-digital) Moderate Risk – Manufacturing / Construction Moderate-High – Professional Services / Legal / Accounting High Risk – Technology / SaaS / E-commerce High Risk – Financial Services / Banking / Insurance Very High Risk – Healthcare / Medical / Pharma Critical – Government Contractors / Defense / Utilities

Industries handling sensitive data or critical infrastructure carry higher premiums.

Number of Sensitive Records Held

Count of customer PII, PHI, financial, or payment card records stored or processed.

Desired Coverage Limit ($)

-- Select Coverage Limit -- $250,000 $500,000 $1,000,000 $2,000,000 $5,000,000 $10,000,000

Maximum payout the insurer will cover per policy period.

Deductible Amount ($)

-- Select Deductible -- $1,000 $2,500 $5,000 $10,000 $25,000 $50,000

Higher deductibles reduce your annual premium.

Security Posture Score

-- Select Security Level -- Poor – No formal controls, no MFA, no training Below Average – Basic antivirus only, minimal policies Average – Firewall, antivirus, basic employee training Good – MFA, patch management, incident response plan Strong – SOC 2 / ISO 27001, EDR, regular pen testing Excellent – Zero-trust, SIEM, 24/7 SOC, full compliance

Stronger security controls significantly reduce your premium.

Prior Cyber Claims in Last 3 Years

-- Select -- None 1 Claim 2 Claims 3 or More Claims

Prior claims history is a major underwriting factor.

Remote Work Percentage (%)

Higher remote workforce percentage increases attack surface exposure.

Third-Party Vendor Access

-- Select -- None – No third-party system access Limited – 1–5 vendors with access Moderate – 6–20 vendors with access High – 20+ vendors or critical system access

Third-party access increases supply chain breach risk.

#### Formula

Step 1 – Base Revenue Premium: Base_Revenue = Annual_Revenue × 0.001 (0.10% of revenue, capped $500–$500,000)

Step 2 – Records Surcharge: Records_Cost = Sensitive_Records × $0.015

Step 3 – Coverage Limit Factor (non-linear): Coverage_Factor = (Coverage_Limit ÷ $1,000,000) ^ 0.65

Step 4 – Deductible Discount: Deductible_Discount = 1 − (Deductible ÷ Coverage_Limit) × 2.5 (clamped 0.60–1.00)

Step 5 – Remote Work Surcharge: Remote_Factor = 1 + (Remote_Pct ÷ 100) × 0.30 (up to +30%)

Step 6 – Final Premium: Premium = (Base_Revenue + Records_Cost) × Coverage_Factor × Deductible_Discount × Industry_Mult × Security_Mult × Claims_Mult × Remote_Factor × ThirdParty_Mult

Step 7 – Floor / Ceiling: Annual_Premium = max($500, min(Premium, $2,000,000))
