How much homeowners insurance do I need?

For your homeowners insurance coverage, experts often recommend you insure your home’s structure for 100% of your home’s estimated replacement cost (or the cost to fully rebuild it today). As a rule of thumb, consider selecting personal property coverage equal to 50-70% of your home’s coverage and at least enough liability coverage to protect all of your financial assets.

When determining coverage limits (or the maximum amount your insurer will pay for a claim), remember construction costs are always changing. It’s important to update your policy limits periodically to reflect current prices and local labor rates.

How do you calculate how much homeowners insurance you need? 

At a glance, here are a few of the key steps:

1. Estimate your home’s replacement cost. There are multiple ways to calculate homeowners insurance coverage. You can estimate how much dwelling coverage you need by multiplying your home’s square footage by local construction costs, getting an estimate from a contractor or appraiser, or asking your insurer. 

2. Inventory your belongings. Add up the value of your furniture, electronics, clothing, and other possessions to see whether your insurer's default personal property coverage is sufficient. The National Association of Insurance Commissioners (NAIC) offers a free home inventory app to make it easier.

3. Choose liability limits. Consider your net worth, household assets, and risk factors, such as owning a pool or having a dog, which increases your risk of liability claims.

4. Review coverage requirements and local risks. Check your lender’s insurance requirements and local risks, such as flooding or earthquakes, that may make add-on coverages like earthquake insurance or separate policies like flood insurance mandatory or recommended. 

How much of each type of coverage do you need?

Choosing the right amount of home insurance starts with understanding what each part of your homeowners policy protects and how insurers calculate coverage limits. Here’s more information on each: 

Here’s a deeper look into each coverage type and the factors that help determine appropriate coverage limits.

How much dwelling coverage do you need?

Dwelling coverage (Coverage A) protects the physical structure of your home, including walls, floors, the roof, and built-in systems such as plumbing, electrical, and some major appliances. You should have enough dwelling coverage to rebuild your home from the ground up after a total loss, like a fire that engulfs the entire structure.

You’ll need to provide your insurance company with information about your home so they can use their valuation tool to determine a minimum coverage amount. Factors that influence rebuild costs and your dwelling coverage amount include:

• Local labor, construction, and materials costs

• Your home’s square footage

• The design and complexity of your home

• Building codes and permit requirements

• Value-added improvements like renovating your kitchen or adding a second bathroom

Your insurer’s estimate is a useful starting point, but you can adjust the limit if needed. If you live in a disaster-prone area like Florida or Colorado, increasing coverage can help cover spikes in post-disaster rebuilding costs. 

Note: Insurance companies don’t use the market value (potential selling price) of your home when determining its replacement cost.

How much other structures coverage do you need? 

Other structures coverage (Coverage B) protects buildings on your property that are not attached to your home, and may include:

• Detached garages

• Sheds

• Fences

• Gazebos

• Guest houses

• In-ground pools (some policies cover swimming pools under dwelling coverage instead)

• Driveways

• Patios 

• Detached workshops 

• Outdoor kitchens

Coverage B is typically set at 10% of your dwelling coverage. For example, if your dwelling coverage is $300,000, you’d have a $30,000 limit for damage to other structures. If you need more coverage, you can increase Coverage B to an amount that will cover all other structures on your property.

Check with your insurer to see what it considers an other structure. Some may include driveways and patios in dwelling coverage, while others cover them under other structures coverage. Where it falls can affect how much coverage you need for each type.

How are claims paid? Actual cash value vs. replacement cost value

In addition to knowing what is covered, it’s important to understand how those items are valued during a claim. Standard homeowners insurance typically covers your dwelling and other "roofed-and-walled" structures — like a detached guest house or shed — on a replacement cost value (RCV) basis, as long as you insure your home for at least 80% of the rebuild cost. This means the insurer pays to repair or replace the damage at today’s prices without deducting for the age or wear of the materials, up to your policy limits. Many policies pay the actual cash value (ACV) (which factors in depreciation) first, then pay the rest once repairs are complete, and some set a deadline for finishing repairs.

However, non-building structures on your property, such as fences, driveways, or awnings, are often covered on an ACV basis. For these, the insurer subtracts depreciation from your payout, reflecting their used value at the time of loss. If you prefer RCV protection for all your property, you may be able to add that coverage to your policy (called an endorsement) for an additional cost.

Note: Regardless of whether you carry RCV or ACV coverage, you are responsible for your deductible. Rather than paying this to the insurer, the amount is typically subtracted from your final claim settlement.

What are extended and guaranteed replacement costs? 

Your insurer may offer extended replacement cost, which pays 10% to 50% above your dwelling limit if rebuilding costs rise, or guaranteed replacement cost, which covers the full rebuild cost even if it exceeds your policy limit. These extended coverages are especially useful in disaster-prone areas, where widespread losses can cause labor shortages and sharp increases in materials and labor costs.

Let’s say your home is a total loss after a hurricane, and you have $400,000 in dwelling coverage, but it costs $500,000 to rebuild. If you have extended replacement cost of 25%, your insurance company could step in to cover up to the additional $100,000. If not, then you’d have to pay the difference. Guaranteed replacement cost — which is becoming increasingly hard to find — would also cover the extra cost, since it pays the full amount to rebuild your home after a disaster.

How much personal property coverage do you need?

Personal property coverage (Coverage C) protects your belongings, including furniture, clothing, electronics, and appliances. Coverage C usually defaults to 50% to 70% of your dwelling coverage, but you can typically increase it if you need more coverage for your stuff.

To determine the right coverage amount:

• Create a home inventory

• Estimate replacement costs for older and more expensive items

• Consider high-value items that may need additional coverage or an endorsement

In a standard policy, personal property is typically covered on an ACV basis. If you don’t want to worry about depreciation factoring into personal property claims, it may be worth paying extra for RCV coverage.

How much loss of use coverage do you need?

Loss of use coverage (Coverage D) helps pay for temporary living expenses if your home becomes uninhabitable due to a covered loss. It covers additional costs you may incur, such as:

• Hotel or rental costs

• Food expenses

• Laundry and transportation costs

• Pet boarding

Coverage limits are typically 20% to 30% of your dwelling coverage. It can help pay for the additional expenses you incur while displaced from your home due to a covered event, up to your policy limit.

Your insurer may have a time or dollar amount cap for loss of use coverage, so it’s important to verify what your policy covers before a disaster strikes. 

How much personal liability coverage do you need?

Personal liability coverage (Coverage E) protects you if you or your family is found legally responsible for injuries or property damage to others. Coverage E can help pay for medical expenses, property replacement, and legal fees and settlements if you’re sued.

The amount of coverage you need depends on your net worth and risk exposure. The higher your net worth and risks (pets, pools, trampolines, teen drivers, frequent guests, etc.), the more coverage you’ll need to adequately protect your finances.

Minimum coverage generally starts at $100,000, but the Insurance Information Institute (Triple-I) recommends carrying $300,000 to $500,000. You can also choose higher amounts, such as $1 million. Anything higher and you’ll usually need a separate umbrella insurance policy.

How much medical payments coverage do you need?

Medical payments coverage (Coverage F) pays for medical costs if a guest gets injured while on your property. It differs from personal liability because you don’t have to be at fault for your insurer to pay the claim. Because of this, payouts are typically disbursed faster, and may help avoid lawsuits. 

The base coverage is usually $1,000 per person, per accident, but you can often increase it up to $5,000 for an added premium.

What other homeowners insurance coverages might you need?

Standard policies don’t cover everything. The following add-ons can help fill coverage gaps, depending on your situation:

• Water backup coverage: Helps pay for damage caused by backup of sewer or drains and sump pump failures

• Flood insurance: Covers damage from flooding (requires a separate policy through the National Flood Insurance Program or a private insurer)

• Earthquake coverage: Covers damage from earthquakes and other seismic events (some insurers offer this as an add-on; others require a separate policy)

• Ordinance or law coverage: Pays for required code upgrades during repairs in a covered claim

• Equipment breakdown coverage: Covers repairs or replacement of appliances or systems after sudden failures

• Scheduled personal property coverage: Covers high-value items like art, collectibles, electronics, and jewelry for their appraised value

If you live in a coastal or storm-prone area, your policy may have a separate deductible for hurricanes or wind and hail. Check your policy or ask your insurer to confirm.

Frequently asked questions

What is the 80% rule for home insurance?

The 80% rule for home insurance means insurers expect you to insure your home for at least 80% of its replacement cost. If you fall below that threshold, you may get a lower claim payout, even for partial losses. Because of this, insuring your home for its full replacement value (or the cost to rebuild it today) is recommended.

How much is homeowners insurance on a $400,000 or $500,000 house? 

Your homeowners insurance premiums are based on the cost to rebuild your home, not its market value. The national average for a home insured for $400,000 in dwelling coverage is around $1,679 per year, while a home with $500,000 in dwelling coverage costs around $1,973 per year, according to the National Association of Insurance Commissioners (NAIC). 

Does your mortgage lender decide how much coverage you need?

You’ll select your coverages, but your mortgage lender will likely require certain minimum coverage levels as part of your mortgage agreement. For example, your lender may require you to insure your home’s structure for 80% of the cost to rebuild it, but you may choose a higher coverage level to protect against a total loss. Use your insurer’s replacement cost estimate as a starting point and review your coverage limits to make sure it fits your needs and fully protects you.

How often should you review your coverage?

Review your homeowners insurance coverage at least once a year and after major renovations, home improvements, or expensive purchases. These changes may increase rebuilding costs or the value of your belongings. You can also ask your insurer about adding extended replacement cost to your policy, which can step in to provide additional protection if needed during a covered loss.
