- Enter a modeled covered loss. Use the dollar amount of damage you want to test before deductible and policy limit.
- Enter the applicable deductible. Use the deductible for the specific claim scenario.
- Enter the applicable policy limit. Use the maximum amount available for the coverage being modeled.
- Set the annual claim probability. Enter a probability from 0% to 100% for this representative loss scenario.
- Review maximum and expected payouts. The breakdown shows the modeled insurer payment if the loss occurs; the main result applies the probability weight.
Home Insurance Expected Claim Calculator
Estimate the expected dollar value of a home insurance claim from a modeled covered loss, deductible, policy limit, and annual probability. The calculator first determines how much the policy could pay for the representative loss after the deductible and limit, then weights that payout by the probability you enter. This separates severity from frequency: a large possible loss can have a high claim payment but a lower expected value when its assumed probability is small. The output can support scenario comparisons across deductibles or limits, but it does not predict whether a particular future loss will be covered.

Maximum modeled payout = min(max(0, Loss − Deductible), Policy limit)Expected claim payout = Maximum modeled payout × p
Where:
- Loss = modeled covered loss amount in dollars
- Deductible = applicable deductible in dollars
- Policy limit = maximum modeled insurer payment for the coverage
- p = annual probability of the modeled covered claim as a decimal
Assumptions: The loss is assumed covered except for the deductible and policy limit. Real claims can also involve exclusions, sublimits, depreciation, replacement-cost conditions, coinsurance, multiple deductibles, and claim adjustment.
What the result means
The main result is a probability-weighted value, while the maximum modeled payout is the amount the insurer could pay in the simplified scenario if the claim occurs.
Expected value is a planning concept and should not be read as a promised refund of premiums or a guaranteed future claim payment.
Given: Modeled covered loss = $50,000; deductible = $2,000; applicable limit = $300,000; annual probability = 6%.
Calculation: Maximum modeled payout = min(max($0, $50,000 − $2,000), $300,000) = $48,000. Expected claim payout = $48,000 × 0.06 = $2,880. Policyholder loss before other policy terms = $50,000 − $48,000 = $2,000.
Result: The expected claim payout is $2,880.
Interpretation: If the representative loss occurs and is covered as modeled, the insurer payment would be $48,000; $2,880 is the annual probability-weighted value of that payment.
Why is the expected payout not the same as the claim payment?
The claim payment is conditional on the loss occurring. Expected payout multiplies that conditional amount by the probability entered.
What if the loss is smaller than the deductible?
The modeled insurer payout is zero because the entire loss falls below the deductible.
How does the policy limit affect a large loss?
After subtracting the deductible, the modeled insurer payout cannot exceed the entered limit. Any amount above that simplified limit remains outside the modeled payment.
Does this include depreciation or replacement-cost settlement rules?
No. The calculator assumes the entered loss is payable except for deductible and limit. Actual settlement can depend on valuation terms and proof of repair or replacement.
Can I compare two policies with this calculator?
Yes, by running the same loss and probability with different deductibles or limits. Keep the claim scenario consistent when comparing outputs.
