Home Insurance Cost Estimator by State (2026)

How It Works

Homeowners insurance is priced on rebuild cost — what it would take to reconstruct your home from scratch — not on what your home would sell for. That is why the two numbers that matter most are where you live and how much dwelling coverage you buy. This estimator starts from the published 2026 average premium for your state at five dwelling-coverage levels ($200,000, $300,000, $400,000, $600,000 and $1,000,000), then interpolates to your exact coverage amount and adjusts for your deductible. The underlying figures come from Insurance.com's 2026 rate analysis of Quadrant Information Services data, covering $300,000 of liability coverage and a $1,000 deductible unless stated otherwise.

The national average in that analysis is $2,872 a year — about $239 a month — for $300,000 of dwelling coverage. But the national figure hides an enormous spread: Florida averages $8,471 a year for the same coverage, while Hawaii averages just $738. The five most expensive states are Florida ($8,471), Nebraska ($5,513), Colorado ($5,511), Oklahoma ($5,378) and Kansas ($5,289); the cheapest are Hawaii ($738), Vermont ($1,017), Maine ($1,299), New Hampshire ($1,324) and Pennsylvania ($1,434). Severe weather, rebuild costs, litigation and state regulation all push rates apart, which is why a state average is a far better starting point than a national one.

Worked Example

A home in Texas with $300,000 of dwelling coverage and a $1,000 deductible sits exactly on a published data point: the Texas average for that profile is $4,582 a year, or $381.83 a month. The estimator shows a range of $3,666 to $5,498 a year (the central estimate plus or minus 20%), because individual quotes vary widely around any state average. Texas runs 59.5% above the $2,872 national average, mostly because of hail, wind and storm risk.

A second example shows how the interpolation works. Take a home in Ohio with $250,000 of dwelling coverage and a $2,500 deductible. Ohio's published averages are $1,687 at $200,000 of coverage and $2,109 at $300,000, so $250,000 sits exactly halfway: $1,687 + ($2,109 − $1,687) ÷ 2 = $1,898 at a $1,000 deductible. The $2,500 deductible factor is 0.9120 (derived from Insurance.com's published national averages across coverage levels), giving $1,898 × 0.9120 = $1,731 a year, or $144.25 a month, with a range of $1,385 to $2,077.

Assumptions

• Premiums are interpolated linearly between the five published coverage anchors for your state ($200,000, $300,000, $400,000, $600,000, $1,000,000). Below $200,000 and above $1,000,000 the nearest segment's slope is extended.
• All state figures assume $300,000 of liability coverage and a $1,000 deductible, matching the published table. The national $1,000,000 anchor ($7,703) is derived from Insurance.com's published $7,025 at a $2,500 deductible, adjusted by the published deductible ratio.
• Deductible factors are derived from Insurance.com's published national averages: $500 = 1.0909 (from the published $512 saving when moving from a $500 to a $2,500 deductible at $300,000 of coverage), $1,000 = 1.0000, $2,500 = 0.9120 (the average ratio across the four published coverage levels), $5,000 = 0.8423.
• The range shown is the central estimate ±20% — our planning band, not a published statistic. Treat it as the spread your quotes are likely to fall within, not a promise.
• Home age and construction do not change the estimate. They only affect the guidance note, because no single published multiplier table covers them: newly built homes average about 36% less than older homes nationally (Insurance.com, 2026), and brick or masonry homes typically cost 5–15% less to insure than wood-frame homes.
• Hurricane deductibles, flood cover, earthquake cover, roof age, claims history, credit-based insurance score and discounts are not included — all of them move real quotes.

The table below shows the published national averages by dwelling coverage and deductible, so you can see both levers at once:

Two patterns stand out. First, doubling dwelling coverage from $300,000 to $600,000 raises the average premium from $2,872 to $4,960 — a 73% rise, not a doubling — because part of every premium covers liability and fixed costs that do not scale with the house. Second, raising the deductible from $1,000 to $2,500 saves $223 to $383 a year depending on coverage, roughly 9% of the premium.

How to Use This Calculator

Pick your state first — location is the single biggest driver of the result. Then enter your dwelling coverage: the cost to rebuild your home, which your insurer's replacement-cost estimate will tell you (it is usually higher than the market value in cheap areas and lower in expensive ones). Choose your deductible, then your home's age and construction type for the guidance note. The headline result is an annual premium range with the central estimate and monthly figure underneath, plus your state's $300,000 average and how it compares with the national $2,872.

Use the CSV download to see the same estimate across all five coverage levels for your state at your chosen deductible — handy if you are deciding how much coverage to buy. If your home's rebuild cost is near a round number, try the coverage levels on either side: the premium curve flattens as coverage rises, so the jump from $300,000 to $400,000 costs less than the jump from $200,000 to $300,000.

Tips and Practical Advice

Compare quotes from at least three insurers — the same home can be quoted hundreds of dollars apart, and the cheapest company in one state is rarely the cheapest in the next. Raising your deductible is the most reliable way to cut the premium: moving from $1,000 to $2,500 saves about $251 a year on a $300,000 policy nationally, but only do it if you can comfortably pay the higher amount after a loss.

Check the discounts you may already qualify for: bundling home and auto cover, a monitored alarm, a new roof, and a claims-free history all commonly reduce premiums. And review your dwelling coverage every year or two — rebuild costs have risen sharply, and a limit set three years ago may no longer cover a full rebuild. Under-insuring to save $100 a year can cost tens of thousands after a major claim, because many policies only pay in full if your coverage is at least 80% of the rebuild cost.

Finally, remember what a standard policy does not cover. Flood damage needs separate flood insurance in almost every state, earthquake cover is a separate add-on in quake zones, and in Hawaii hurricane damage needs a separate policy — one reason Hawaii's standard-policy average looks so low. If you live in a high-risk area, price those add-ons before you judge any estimate complete.
