Example Data Table
These scenarios illustrate different deductible styles and coinsurance settings.
| Scenario | Loss | Deductible | Coinsurance | Policy limit | Estimated insurer pay | Estimated your share |
|---|---|---|---|---|---|---|
| Auto collision | $8,000.00 | $1,000.00 fixed | 100% | — | $7,200.00 | $1,000.00 |
| Home wind damage | $30,000.00 | 2.00% of $250,000.00 | 100% | $25,000.00 | $23,000.00 | $5,000.00 |
| Health outpatient | $4,200.00 | $500.00 + 0.00% | 80% | — | $3,120.00 | $1,080.00 |
Formula Used
1) Main claimable after adjustments
MainClaimable = max(0, Loss × (1 − Depreciation%) − Recoveries)
2) Total claimable amount
TotalClaimable = MainClaimable + AdditionalCoverages
3) Deductible (per occurrence)
Fixed: D = FixedAmount
Percentage: D = InsuredValue × DeductibleRate%
Combined: D = FixedAmount + (InsuredValue × DeductibleRate%)
Optional min/max clamps apply to D.
4) Deductible applied to this submission
DeductibleApplied = min(TotalClaimable, max(0, (D × Occurrences) − DeductibleAlreadyMet))
5) Estimated insurer payment
AfterDeductible = max(0, TotalClaimable − DeductibleApplied)
InsurerBeforeLimit = AfterDeductible × Coinsurance%
InsurerPayment = min(InsurerBeforeLimit, PolicyLimit) when a limit is provided.
How to Use This Calculator
- Enter the gross loss amount and any extra coverages or expenses.

- Choose your deductible type and fill only the relevant fields.
- If your plan uses coinsurance, set the insurer pays percentage.
- Add a policy limit if your coverage caps insurer payment.

Deductible drives immediate out-of-pocket
If total claimable is $10,000 and the deductible is $1,000, the insurer starts from $9,000. With 100% coinsurance and no limit, insurer pay is $9,000 and your share is $1,000. Depreciation and recoveries reduce claimable first, so a 10% depreciation on $10,000 lowers the base by $1,000 before deductible.
Fixed versus percentage deductibles
A fixed deductible stays constant per claim, such as $500 or $1,500. A percentage deductible scales with insured value, such as 2% of $250,000 = $5,000. This calculator supports combined structures too, for example $1,000 + 1% of $150,000 = $2,500, then optional minimum and maximum caps refine the final deductible. If a deductible was already met, that credit is subtracted before applying it to the claim.
Coinsurance changes the split after deductible
Coinsurance applies after deductible. Using $12,000 claimable and $2,000 deductible, the post‑deductible base is $10,000. At 80% coinsurance, insurer share is $8,000 and your share is $4,000. At 90%, insurer share becomes $9,000 and your share falls to $3,000. For two occurrences, the deductible doubles and can change both shares.
Policy limits can cap the settlement
Limits apply after coinsurance in this model. If coinsurance produces $30,000 but the policy limit is $25,000, the insurer payment is capped at $25,000 and the remaining $5,000 shifts to your responsibility. Setting the limit to 0 disables the cap. When a limit binds, increasing the deductible may not reduce insurer pay further if the cap is already reached.
Sensitivity example you can replicate
Try the same loss twice to see the deductible effect. Example: claimable $18,000, coinsurance 100%, no limit. With $500 deductible, insurer pay is $17,500. With $2,500 deductible, insurer pay is $15,500. The difference, $2,000, is entirely borne by you, even though the loss did not change. Use the chart to confirm it.
FAQs
1) What does “total claimable” represent?
It is the amount available for settlement after depreciation, recoveries, and added coverages. Deductible and coinsurance are applied to this figure.
2) How do I calculate a percentage deductible?
Enter the insured value and the deductible rate. The calculator multiplies them to get the per‑occurrence deductible, then applies any minimum or maximum limits you enter.
3) What if I already met part of my deductible?
Use “deductible already met” to credit what you have satisfied during the coverage period. The tool subtracts that amount before applying the remaining deductible to this claim.
4) Does coinsurance apply before the deductible?
No. The calculator applies the deductible first, then applies the insurer pays percentage to the remaining amount. This matches many coinsurance structures, but always follow your policy wording.
5) How are multiple occurrences handled?
If the deductible applies per occurrence, set the occurrences count. The tool multiplies the per‑occurrence deductible and then caps the applied deductible so it cannot exceed the total claimable.
6) Why might insurer payment be capped?
If you enter a policy limit, the insurer payment cannot exceed that limit, even if coinsurance would produce a higher amount. Leave the limit as 0 to disable the cap.
