Cyber Insurance Expected Claim Calculator

Estimate the expected claim payment from a cyber insurance scenario using incident probability, a representative covered loss, the deductible, and the applicable policy limit. The calculator first determines the modeled payment if an incident occurs, then weights that payment by the entered probability.

Businesses can use the result as one input when comparing retention levels, limits, and premiums. Because real cyber policies may have sublimits, coinsurance, waiting periods, and coverage-specific conditions, the estimate should be read as a simplified risk model rather than a quote or coverage determination.

1. Set the claim probability
Enter the estimated chance of at least one comparable covered cyber incident during the same policy year used for the rest of the inputs.

2. Enter a representative covered loss
Use the modeled loss before applying the deductible and applicable limit.

3. Enter the deductible
Use the amount retained before insurer payment for the modeled claim.

4. Enter the applicable limit
Use the limit that would apply to this loss scenario, not necessarily the policy aggregate if a smaller sublimit applies.

5. Review claim and expected values
The page shows both the payment if a claim occurs and the probability-weighted expected payment.

Payment if claim occurs = min(max(Covered loss − Deductible, 0), Policy limit) Expected insurer payment = Claim probability × Payment if claim occurs

The model assumes the entered probability and representative loss describe one comparable claim scenario for the selected period. It does not model multiple claims, coinsurance, benefit schedules, or uncovered portions unless they are reflected in your inputs.

What the result means

The main result is the probability-weighted insurer payment for the scenario you entered.

Actual claim payments are governed by policy wording, limits, exclusions, and claim-specific facts.

Given: Assume a 10% annual chance of a $120,000 covered cyber incident, a $5,000 deductible, and a $250,000 applicable limit.

Calculation:
Payment if claim occurs = min(max($120,000 − $5,000, 0), $250,000) = $115,000.00
Expected insurer payment = 10% × $115,000.00 = $11,500.00

Result: The modeled expected insurer payment is $11,500.00 for the selected period. This is a probability-weighted average, not the amount of a guaranteed future claim.

Why is expected claim value lower than the possible claim payment?

Expected value multiplies the payment by the chance of the claim occurring. A large possible claim can therefore have a much smaller probability-weighted value.

What happens when the loss is below the deductible?

The modeled insurer payment becomes zero because the deductible fully absorbs the entered covered loss.

How does the policy limit affect the result?

The payment if a claim occurs cannot exceed the applicable limit entered. If a sublimit applies to the specific loss, use that smaller amount.

Can I use this result to decide whether a premium is fair?

You can compare the expected claim value with premium as one reference point, but premium also reflects expenses, capital, uncertainty, catastrophe exposure, and other underwriting factors.

Does the calculator account for exclusions or denied claims?

No. The loss input should represent an amount you are assuming is covered. Actual coverage depends on policy terms and claim facts.
