Home Coverage Amount Estimator

Estimate what it would cost to rebuild your home and see whether your dwelling limit is high enough to pay a full claim.

Quick answer: Estimate what it would cost to rebuild your home, compare it with your dwelling coverage limit, and see how the common 80 percent rule could change a partial claim. Enter home size, rebuild cost per square foot, finish and code upgrade share, and dwelling limit to personalize the estimate. It returns rebuild cost, coverage gap, and limit as share of rebuild cost so you can compare the impact before choosing a next step. Use it to compare long-term value, tax impact, risk, time horizon, and contribution choices.

Frequently Asked Questions

Everything you need to know.

What does an example Home Coverage Amount Estimator calculation look like?
Using this calculator's own default assumptions, a 2,000 square foot home at $200 per square foot with 10 percent added for finishes and code upgrades has an estimated rebuild cost of $440,000. A dwelling limit of $360,000 is about 81.8 percent of that, which leaves a gap of $80,000. The $200 per foot is an example value, not market data. Enter your own numbers above.
Should I insure my home for what it would sell for?
No. Sale price includes land and neighborhood demand, neither of which an insurer pays to rebuild. Dwelling coverage is meant to cover the cost of rebuilding the structure, so use a rebuild cost per square foot from a builder, an appraiser, or your insurer's own estimate.
What is the 80 percent rule?
Many replacement-cost policies say they will pay a partial loss in full only if your dwelling limit is at least 80 percent of the rebuild cost. Below that line, the payout on a partial loss is usually cut in proportion. Your policy wording controls this, and some policies use a different percentage or pay on actual cash value, so check the loss-settlement section.
Why does the calculator show a payout for a partial loss?
It shows how a limit below the 80 percent line can reduce a smaller claim. It is a simplified proportional estimate that ignores depreciation, sub-limits, and special deductibles. Your insurer's adjuster applies the exact wording of your policy.
Does this estimate cover flood or earthquake?
No. Standard homeowners policies generally exclude flood and earthquake, and those are bought separately. The estimate also leaves out land, detached structures, and extra living costs.
Is the Home Coverage Amount Estimator free to use?
Yes. SwitchWize calculators are free, and you do not need an account to run scenarios or view the result.
Does using the Home Coverage Amount Estimator affect my credit score?
No. Using a calculator does not trigger a credit check. A credit impact can occur only if you apply directly with a lender, card issuer, or provider.
Are the results personalized financial advice?
No. Calculator outputs are educational estimates based on the inputs you enter. Review assumptions and confirm terms directly with providers before making a financial decision.
What should I do after seeing the result?
Use the recommendation module on this page to see the insurance hub, or run Money Map to compare this investing & retirement decision with your other opportunities.
How does SwitchWize choose related offers?
Related offers are matched by the calculator surface (none) and ranked using SwitchWize data such as rate, fees, trust signals, product fit, and switching friction. Paid relationships do not change organic ranking order.
How fresh are the rates and offers shown?
Rate and offer data is reviewed on a recurring cadence and every offer module shows review context or links to the methodology and disclosure pages.
Where can I see the ranking methodology?
The SwitchWize methodology page explains how rate freshness, editorial review, affiliate disclosure, and category ranking factors work.
Can Money Map use this result?
Yes. Money Map is the broader diagnostic path: it compares savings, mortgage, cards, and debt so you can see whether this calculator result is your highest-impact next move.

Why This Matters

Your dwelling limit is the most your insurer will pay to rebuild the house. Market value is the wrong yardstick, because it includes land and location. What counts is the price of lumber, labor, and finishes after a loss. If your limit is too low, a large claim can leave you paying the difference. Many replacement-cost policies also want you to insure at least 80 percent of the rebuild cost before they pay partial losses in full, so a small shortfall can shrink even a small claim.

How to Use It

  1. 1Enter the size of your home in square feet.
  2. 2Enter a rebuild cost per square foot from a local builder or from the replacement-cost figure on your insurer's quote.
  3. 3Add a percentage if you have premium finishes or if local rules would force upgrades when you rebuild.
  4. 4Enter your dwelling coverage limit from your policy declarations page.
  5. 5Add the value of your belongings, an example partial loss, and your deductible to see the effect on a smaller claim.
