How much homeowners insurance do I need?

The short answer

Your dwelling limit, Coverage A, should equal what a local builder would charge to rebuild your house today at current labor and material prices. Every other limit on the policy is derived from that number, which is why getting Coverage A wrong quietly breaks the whole policy.

• Coverage A: full reconstruction cost, not market value, not the mortgage balance, not the tax assessment.
• Coverage B: about 10% of Coverage A for detached structures, more if you have a big garage, barn or fence run.
• Coverage C: typically 50% to 70% of Coverage A for personal property, on a replacement cost basis.
• Coverage D: 20% to 30% of Coverage A for loss of use, ideally with a 24-month rebuild window.
• Coverage E: $300,000 to $500,000 of liability, then an umbrella policy above it.
• Endorsements: extended replacement cost, inflation guard, water backup, and scheduled items for anything valuable.

Use the calculator to get a defensible starting point, then have a carrier run a full reconstruction estimate on your specific address.

Replacement cost, market value and actual cash value

Three different numbers get confused constantly, and only one of them belongs on your declarations page.

• Replacement cost is what it costs to rebuild the same structure at today's prices, including demolition, debris removal, permits, architect fees and the premium a builder charges on a one-off job. This is what Coverage A should equal.
• Market value is what a buyer would pay for the house and the land. Land does not burn. In expensive metros market value often exceeds rebuild cost, and in low-cost or rural markets rebuild cost frequently exceeds market value, which is where underinsurance hides.
• Actual cash value is replacement cost minus depreciation. The Texas Department of Insurance shows the gap plainly: on a $200,000 home with a 2% ($4,000) deductible and a $10,000 roof loss, replacement cost coverage pays $6,000 regardless of roof age, while actual cash value pays $4,500 on a 5-year-old roof, $3,000 on a 10-year-old roof and $0 on a 20-year-old roof.

Home insurance has repriced hard. NAIC data published by Triple-I put the average HO-3 premium at $1,569 in 2022, an 11.2% one-year jump, and CNBC reported in August 2026 that premiums rose roughly another 7% since the start of 2025 on the Bureau of Labor Statistics producer price index. Rebuild costs moved with them, which is why a limit set five years ago is probably wrong today.

Coverage A through F, explained

A standard HO-3 policy is six coverage parts. The California Department of Insurance residential insurance guide and Triple-I describe them as follows:

Two details worth knowing. Triple-I notes that detached structures are generally covered for about 10% of the dwelling amount, personal property for 50% to 70%, trees and shrubs at roughly $500 per item, and unauthorized credit card use up to $500. Loss of use is a separate pot from the rebuild money, so exhausting Coverage D does not reduce what is available to rebuild the house.

Extended and guaranteed replacement cost

Even a good reconstruction estimate can miss. After a wildfire, hurricane or hail outbreak, local labor and materials spike, a phenomenon insurers call demand surge. Two endorsements exist for exactly that.

• Extended replacement cost adds a defined cushion above Coverage A, usually 10%, 25% or 50%. On a $500,000 dwelling limit, a 25% extension gives you $625,000 of rebuild money. This is the endorsement most homeowners should buy, and it is generally inexpensive relative to the protection.
• Guaranteed replacement cost pays the full cost to rebuild with no stated ceiling. It is the strongest form of the coverage, is offered by a minority of carriers, and usually requires you to accept the carrier's own valuation, keep the limit updated and meet age or condition requirements on the home.

Inflation guard is the third piece. It automatically increases Coverage A each year by an index of local construction costs, typically 2% to 6%, so the limit does not decay between renewals. Turn it on and then still review the limit annually, because an index will not capture a kitchen renovation or a finished basement.

Personal property and scheduling valuables

The default Coverage C amount is a formula, not a measurement. Walk your house room by room with your phone camera and add it up. Most households discover the truthful number is higher than 50% of Coverage A once they count electronics, tools, kitchen equipment and a decade of furniture.

Then handle the categories with special limits. Triple-I notes that expensive items such as jewelry, furs, art, collectibles and silverware are covered but usually carry dollar caps if stolen, and that off-premises property is sometimes limited to 10% of the personal property amount. Typical HO-3 caps look like this, though they vary by form and carrier:

A scheduled personal property endorsement, also called a floater, insures a listed item for an appraised value, usually with no deductible and broader perils including mysterious disappearance. It is the correct answer for an engagement ring, a camera kit, a bike worth four figures or an instrument.

Finally, choose replacement cost on contents rather than actual cash value. Triple-I estimates replacement cost coverage runs about 10% more than actual cash value, and it is the difference between a check for a new sofa and a check for a nine-year-old sofa.

How much liability to carry

Triple-I reports that home liability limits generally start at about $100,000, which is far too low for most owners. Its own loss data show why the tail matters: liability claims are rare, roughly 1 in 1,150 policies per year, but the average liability claim for bodily injury and property damage ran $37,174 across 2019 to 2023, and severe cases run into seven figures.

• Start at $300,000, and move to $500,000 if you have equity, a second income or a pool, trampoline or dog.
• Add an umbrella. Triple-I puts $1 million of umbrella coverage at roughly $200 to $350 a year.
• Raise Coverage F to $5,000 so a guest’s minor injury never becomes a liability claim.
• Check for exclusions on specific dog breeds, short-term rentals and home businesses before you rely on the limit.

Umbrella carriers require underlying limits before they will attach, commonly $300,000 or $500,000 of home liability and 250/500/100 on auto. Sizing home liability at $500,000 usually makes the umbrella cheaper, not more expensive. See umbrella insurance for how the layers work.

Deductibles, including the percentage kind

Home deductibles come in two shapes. A flat dollar deductible, commonly $1,000 to $2,500, applies to most losses. A percentage deductible applies to named storms, hurricanes, wind or hail in many states and is calculated on Coverage A, not on the claim.

That distinction costs people real money. A 2% hurricane deductible on a $450,000 dwelling limit is $9,000 out of pocket before the policy pays a dollar. Texas illustrates the mechanic with a 2% deductible on a $200,000 home equalling $4,000. Read your declarations page for the words "named storm," "hurricane," "wind/hail" and "percentage," and confirm which trigger applies in your state.

Raising a flat deductible from $500 to $1,000 typically trims the premium in the mid single digits to about 25% depending on carrier and state, and the higher the deductible the larger the discount. Only take the discount if you can fund the deductible on the day of the loss, and remember you pay it on every claim.

Coverage requirements, percentage-deductible rules and available endorsements vary by state and carrier. Use the numbers here as a framework, then confirm the specifics on your own declarations page with a licensed agent, and read what homeowners insurance covers before you assume a peril is included.
