Homeowners Insurance Calculator: Estimate Your Coverage Amounts

Homeowners coverage amount calculator

Enter your square footage and a local rebuilding cost. The calculator multiplies them, adds any extra items, and applies the percentages you choose.

Arithmetic only. This calculator works only with the figures you enter. It is not a quote and does not predict what any insurer will charge.

Rebuilding cost vs. market value

Market value includes the land and reflects local demand, while rebuilding cost is what it would take to rebuild the house itself with similar materials after a total loss. Your dwelling limit should track rebuilding cost. In some areas, rebuilding cost is higher than market value; in others, it is lower.

Ask your agent or insurer for a replacement cost estimate, and update it after renovations, additions, or a big jump in local construction costs.

How the percentages work

Many homeowners policies set other structures, personal property, and loss of use as a percentage of the dwelling limit. Ten percent for other structures, 50 to 70 percent for personal property, and 20 to 30 percent for loss of use are common starting points, but insurers and policy forms differ. You can often raise or lower these amounts.

Check the declarations page of any quote to see the actual amounts and whether personal property is valued at replacement cost or actual cash value.

Limits the calculator does not show

• Liability and medical payments limits, which protect you if someone is hurt or you damage someone else's property.
• Special limits on jewelry, firearms, collectibles, and cash; scheduled coverage may be needed.
• Ordinance or law coverage for code upgrades after a loss.
• Extended or guaranteed replacement cost endorsements.
• Separate wind, hail, or hurricane deductibles.
• Flood and earthquake, which require separate policies or endorsements.

Using your results with a quote

Compare the calculator's dwelling figure with the dwelling limit on each quote. If a quote is much lower, ask how the insurer estimated rebuilding cost. Then line up the other coverage parts, deductibles, and endorsements before you compare price. See our home insurance comparison guide.

Homeowners coverage parts to compare

Standard homeowners policies generally exclude flood and earthquake, which need separate coverage.

Rebuilding cost, replacement cost, and actual cash value

The most important number on a homeowners policy is the dwelling limit, and it should reflect what it would cost to rebuild your home, not what the home would sell for. Market value includes land and location, which do not burn down; rebuilding cost depends on square footage, construction type, finishes, local labor, and building-code requirements.

• Replacement cost pays to repair or rebuild with materials of like kind and quality, without a deduction for age.
• Extended replacement cost adds a cushion, often 25% or 50% above the dwelling limit, for price spikes after a regional disaster.
• Actual cash value subtracts depreciation, which can leave a large gap, especially for roofs.
• Ordinance or law coverage helps pay for upgrades required by current building codes during a rebuild.

Ask any insurer how it estimated your rebuilding cost, and review that estimate after renovations.

What to check on any homeowners quote

• Dwelling coverage based on the cost to rebuild, not the market value, plus extended replacement cost if offered.
• Roof settlement terms, such as replacement cost versus actual cash value, and any separate wind or hail deductible.
• Water backup, service line, and ordinance or law coverage, which are often optional.
• Personal property at replacement cost and limits on jewelry, firearms, and electronics.
• Liability limits high enough to meet an umbrella insurer's requirements.

Common exclusions and coverage gaps

Every homeowners policy has exclusions and limits. The ones that surprise homeowners most often are:

• Flood. Excluded from standard policies; available through the National Flood Insurance Program and private flood insurers. See flood insurance.
• Earthquake and earth movement. Usually excluded; available as an endorsement or separate policy in many states.
• Wear, tear, and maintenance. Gradual leaks, rot, and deterioration are generally not covered.
• Sewer or drain backup. Often excluded unless you add a water-backup endorsement.
• Mold. Frequently limited or excluded.
• Business property and activities. Home businesses may need separate coverage.
• Valuables. Jewelry, firearms, and collectibles often have low sublimits unless scheduled.

What affects your home insurance price

Home insurance prices vary widely between insurers for the same house, because each company weighs risk differently. Common factors include:

• Location, including exposure to wind, hail, wildfire, and crime, and distance to a fire station and hydrant.
• Rebuilding cost, construction type, and the age and condition of the roof, plumbing, and electrical systems.
• Your claims history and the property's claims history.
• Deductibles, including separate wind, hail, or hurricane deductibles.
• Protective devices such as monitored alarms, water-leak sensors, and impact-resistant roofing.
• In many states, a credit-based insurance score.

Because insurers file rates at different times, comparing quotes at renewal can reveal large differences.

Ways to lower your home insurance premium

• Compare several insurers with the same dwelling limit and deductibles.
• Raise the all-perils deductible to an amount you could pay without strain, and understand any separate wind or hurricane deductible.
• Bundle home with auto where the combined total is lower than separate policies.
• Ask about protective-device discounts for monitored alarms, smart water shutoffs, and leak sensors.
• Update the roof and ask about impact-resistant or fortified roof credits where offered.
• Avoid small claims that you could pay yourself, since claims history affects future pricing.
• Do not cut the dwelling limit below rebuilding cost to save money; underinsurance can be costly after a large loss.

How to file a home insurance claim

1. Stay safe and prevent further damage. Make reasonable temporary repairs, such as tarping a roof or shutting off water, and keep receipts.
2. Document everything. Take photos and video before cleanup, and list damaged items.
3. Report the claim promptly through the insurer's app, website, or phone line.
4. Meet the adjuster and share your documentation and contractor estimates.
5. Review the estimate line by line, and ask how depreciation and recoverable depreciation work on your policy.
6. Keep records of every conversation, and ask your state insurance department for help if a dispute cannot be resolved.

Switching home insurers without a gap

Switching home insurers is usually straightforward, but a few details matter. Start the new policy on the same day the old one ends so there is no gap. If your premium is paid through a mortgage escrow account, send the new declarations page and mortgagee clause to your lender, and confirm that the lender pays the new insurer and stops paying the old one. Cancel the old policy in writing and ask for any prorated refund. If you switch mid-term, check for short-rate cancellation fees.

Umbrella coverage on top

Personal umbrella insurance adds liability protection above your home and auto limits, usually in $1 million increments. Most umbrella insurers require minimum underlying limits on both policies, and many offer better pricing when home and auto are with them. If you have significant assets or a teen driver, price an umbrella as part of any home and auto comparison. See our umbrella insurance page.

How to check any insurer before you buy

Before you buy from any company, take a few minutes to check it:

• License. Confirm the insurer is licensed in your state through the state insurance department's company lookup.
• Complaints. The NAIC's Consumer Insurance Search shows complaint counts and a complaint index for each company, where 1.00 is the expected level for the company's size.
• Financial strength. Ratings from agencies such as A.M. Best describe an insurer's ability to pay claims.
• Legal name on the quote. Large groups write policies through several companies with different rates and rules. Make sure you know which one issues your policy.
• Claims process. Ask how claims are reported, whether there is a preferred repair-shop program, and how quickly adjusters respond after storms.

How we approached this review

We built this review from public sources rather than test purchases or claims we filed ourselves. That approach has limits, so it helps to know what we looked at and what we did not:

• What we reviewed: the company's own website and policy descriptions, its press releases and investor materials where available, state availability statements, and independent reporting.
• What we compared: how the product is bought and serviced, how it is priced, which coverages it offers, and the trade-offs that matter for different kinds of drivers or households.
• What we did not do: assign star ratings, publish prices of our own, or claim personal claims experience. Prices are individual, and claims experiences vary widely from one customer to the next.

Products, states, and terms change. Before you buy, confirm current details with the company and read the policy documents, which control over any summary, including this one.

What to have ready for a quote

These details help produce accurate quotes.

1. Property details. Address, year built, square footage, and construction.
2. Roof. Age, material, and any replacement records.
3. Current declarations page. To match limits and deductibles.
4. Claims history. Property claims in the past five years.
5. Updates and features. Plumbing, electrical, heating, alarms, and mitigation features.
