Understanding coverage gap estimate

What this calculation is for
A coverage-gap check compares a replacement need with insurance limits and money reserved for a loss. It can highlight underinsurance, but cannot decide whether a policy is suitable or whether a specific claim will be covered.
How the method works
Replacement needs are projected using the entered inflation and review period, then compared with coverage, deductible assumptions and available reserves. Verify each result label because a coverage limit, a deductible and a cash reserve are not interchangeable forms of protection.
A worked example
If rebuilding is estimated at $400,000 but a policy limit is $300,000, a $10,000 cash reserve does not eliminate the remaining replacement exposure. An insurer’s valuation and settlement terms can differ from the estimate.
Assumptions and real-world differences
Actual-cash-value settlements, exclusions, sublimits, coinsurance penalties, flood or earthquake coverage and policy endorsements are not assessed. A budgeted replacement value is not a professional appraisal or a binding insurer valuation.
Using the coverage gap estimate estimate
Start with the assumptions that match your situation, then read the headline together with the detailed breakdown. This tool’s baseline calculation uses estimated replacement value, current coverage limit, deductible, additional cash reserve, annual replacement-cost increase, years until review. Changing an input changes only the modeled consequences of that input; it does not retrieve a quote or validate your eligibility.

Frequently asked questions
- Does the result mean a claim will be paid?
- No. Coverage depends on the policy wording, cause of loss, limits and claim assessment.
- Is market value the same as replacement cost?
- No. Land, location and market demand affect sale value differently from the cost of rebuilding.
- Do the example defaults represent a recommended plan?
- No. Defaults make the method inspectable. Replace them with relevant assumptions and test a less favorable case before making a decision.
