Disability Insurance Expected Claim Calculator

This calculator estimates a probability-weighted disability insurance claim from a monthly benefit, an assumed probability of disability during the analysis horizon, an elimination period, and an expected disability duration. It is designed for scenario modeling rather than policy pricing.

Because real disability claims vary widely in duration and may involve partial or residual benefits, offsets, taxes, and policy definitions, the calculator intentionally uses a transparent single-duration assumption that you can change.

1. Enter the monthly benefit
Use the policy benefit amount for the scenario.

2. Set the disability probability
Enter your own probability that a qualifying disability begins during the analysis horizon.

3. Enter the elimination period
Use the waiting period before benefits would start.

4. Estimate disability duration
Enter the total duration from disability onset, including the elimination period.

5. Review payable months
The model subtracts the waiting period, converted to months, from the assumed duration and floors the result at zero.

6. Read expected claim value
The claim amount if disability occurs is multiplied by the probability you supplied.

Payable months = max(Expected disability months − Elimination days ÷ 30, 0) Claim if disability occurs = Monthly benefit × Payable months Expected claim value = Claim if disability occurs × Disability probability

This model assumes a constant monthly benefit throughout the payable period and does not model partial disability, benefit caps, COLA riders, offsets, or taxes.

What the result means

The expected claim value is the probability-weighted payout under the duration and probability assumptions you entered.

A private policy may define disability differently from Social Security or another program, so qualification for one benefit does not automatically imply qualification for another.

Given: $3,500 monthly benefit, 12% disability probability, 90-day elimination period, and 18-month expected duration.

Calculation: Waiting period = 90 ÷ 30 = 3 months. Payable months = 18 − 3 = 15. Claim if disability occurs = $3,500 × 15 = $52,500. Expected claim value = $52,500 × 0.12 = $6,300.

Result: Expected claim value = $6,300.

Interpretation: The figure is an average scenario value, not a prediction that a particular claim will pay $6,300.

What happens if the disability duration is shorter than the elimination period?

Modeled payable months fall to zero, so the expected claim value is zero. A real policy may have detailed rules for recurrent or successive disabilities.

Where should the disability probability come from?

Use an assumption appropriate to your analysis. This calculator does not infer individual disability risk from occupation, age, medical history, or national statistics.

Does the model include partial or residual disability?

No. It assumes the full monthly benefit is payable after the elimination period for the modeled duration.

Are benefit offsets included?

Not automatically. Employer benefits, Social Security, workers compensation, and other sources can affect private-policy payments depending on the contract.

Why is the probability entered for the whole horizon instead of annually?

This version keeps the model transparent by accepting one cumulative probability for the analysis period, avoiding assumptions about annual independence and changing risk.
