How to use this calculator

What this calculator does

Estimate a coverage gap and possible out-of-pocket exposure from replacement cost, current coverage, and deductible.

Insurance results are estimates for planning and education. They are not insurance, legal, tax, or financial advice, and they do not determine eligibility, pricing, coverage approval, or claim outcomes.

Scenario guidance

When to use this

Use this when reviewing whether a coverage limit appears lower than an estimated replacement cost.

Example scenario

A homeowner is comparing a current dwelling limit with a recent replacement-cost estimate before asking for an insurance review.

Inputs that usually matter most

  • Estimated replacement cost, because it represents the possible amount needed.
  • Current coverage, which is the policy limit being compared.
  • Deductible, because it may still be paid out of pocket even when coverage applies.

Common mistake to avoid

Do not assume replacement cost, market value, policy limit, and claim payout are the same thing.

How to interpret the result

Use the gap and exposure estimate to identify questions for a policy review, then confirm terms, exclusions, limits, and local rules.

Results are estimates only and are not insurance, legal, tax, or financial advice.

Formula

Out-of-pocket exposure = max(replacement cost - current coverage, 0) + deductible

Coverage gap is the amount by which estimated replacement cost exceeds current coverage. The deductible is added to estimate possible out-of-pocket exposure.

Example coverage gap

A $350,000 replacement cost with $300,000 of coverage and a $2,500 deductible gives a $50,000 coverage gap and $52,500 estimated out-of-pocket exposure.

Frequently Asked Questions

Does this predict my claim payout?

No. Claim payments depend on policy terms, exclusions, limits, deductibles, documentation, insurer decisions, and local rules.

Should replacement cost include inflation?

Use the best current estimate available. Inflation, building costs, and policy endorsements can change the appropriate coverage amount.
