How this calculator works

Percent deductible amount = dwelling coverage x deductible percent. The output uses either the larger of percent and flat deductible or the sum of both, based on the selected editable method.
Percent deductible = dwelling coverage x deductible percent. Estimated deductible is either max(percent deductible, flat deductible) or percent deductible + flat deductible based on the selected method.

Inputs explained

Dwelling coverage

Coverage A or other policy value used for the deductible calculation; verify the declarations page.

Deductible percent

Percent deductible from a policy or quote, not a live or assumed market rate.

Flat deductible

Flat dollar deductible if the policy includes one or if you want to compare a flat scenario.

Combination method

Choose the method that matches the policy terms you have verified.

Understanding your results

The result is an estimated deductible amount, not a claim outcome. Actual responsibility depends on coverage, peril, loss, exclusions, multiple policies, endorsements, and insurer adjustment.

Example scenarios

Planning example

$750,000 dwelling coverage with a 2% deductible and no larger flat deductible estimates $15,000.

Things to Keep in Mind

Planning estimate only; not tax, legal, insurance, utility, financial, or real estate advice. Verify current local rules, policies, rates, exemptions, caps, exceptions, official notices, utility tariffs, insurance declarations, and qualified advisors before relying on any result. This does not determine covered losses, claim payments, exclusions, depreciation, smoke damage treatment, ordinance coverage, FAIR Plan coordination, or insurer obligations.

Tips & Best Practices

  • Read the declarations page and endorsements for deductible wording.
  • Check whether different perils have different deductibles.
  • Keep an emergency reserve target separate from the coverage estimate.
