Home Insurance Calculator
Use this free home insurance calculator to estimate what it costs to insure your home each year. Enter your home value, location risk, deductible, coverage level, and construction type, and it works out an estimated annual premium and monthly cost — with editable default rates you can adjust to match quotes in your area.
What it would cost to rebuild the home, not the market price of the land.

How it works
A home insurance premium is a price for risk. The insurer starts with the value of your home and a base rate, then adjusts that number up or down for the things that make a claim more or less likely, or more or less expensive. A home in a storm zone costs more to insure than the same home in a calm area. A brick home costs less than a wood-frame home, because it burns less easily. Broader coverage costs more, because the insurer pays more when something goes wrong. And a higher deductible costs less, because you cover the first part of every claim yourself.
Home value is the rebuild value — what it would cost to rebuild the home from scratch — not the market price, which includes the land. Land does not burn down, so it is not insured. Location risk reflects weather, crime, and claim history in your area: low risk means few weather or crime claims, moderate is average, and high covers coasts, wildfire zones, and storm-prone areas. Deductible is what you pay out of pocket on each claim before the insurer pays anything. Coverage level is how the insurer values a loss: actual cash value pays the depreciated value, replacement cost pays today's rebuilding price, extended replacement cost pays up to about 125% of the insured value if rebuilding costs more than expected, and guaranteed replacement cost pays the full rebuilding cost no matter how high it runs.
The base rate field starts at 0.35% of the home value per year as an editable planning default from November 2026 — a $350,000 home at that rate has a base premium of $1,225 a year. Rates vary widely by state and insurer, so treat the default as a starting point: if a real quote you have is higher or lower, change the rate to match it and the calculator will adjust everything else around it. Construction type matters because fire and storm damage differ by material: wood frame is the most expensive to insure, brick veneer sits in the middle, masonry and brick are cheaper, and steel or concrete are the cheapest. This estimate does not include flood or earthquake coverage, which are separate policies, and it does not reflect your claims history, credit score, or the age of your roof — all of which a real quote will weigh.
Worked example
Suppose you insure a $350,000 wood-frame home in a moderate-risk area, with a $1,000 deductible and replacement cost coverage, at the default base rate of 0.35%. Here is how the premium works out, step by step.
Step 1: Find the base premium. $350,000 × 0.35% = $350,000 × 0.0035 = $1,225.00 per year.
Step 2: Apply the location risk factor. Moderate risk is 1.00, so the premium stays at $1,225.00.
Step 3: Apply the coverage factor. Replacement cost is 1.15, so $1,225.00 × 1.15 = $1,408.75.
Step 4: Apply the construction factor. Wood frame is 1.10, so $1,408.75 × 1.10 = $1,549.62.
Step 5: Apply the deductible factor. A $1,000 deductible is 1.00, so the annual premium is $1,549.62, which is $129.14 a month.
Enter the same numbers — $350,000 home value, moderate risk, $1,000 deductible, replacement cost, wood frame, 0.35% base rate — and the calculator shows exactly the same result: $1,549.62 per year, or $129.14 per month. Raise the deductible to $2,500 and the same home drops to about $1,394.66 a year — try it in the deductible selector.
FAQ
What does home insurance cover?
A standard policy covers the structure of your home, your personal belongings, liability if someone is hurt on your property, and extra living costs if you have to move out during repairs. Floods and earthquakes are usually not covered and need separate policies.
What is the difference between replacement cost and actual cash value?
Replacement cost pays what it costs to rebuild or replace the item at today's prices, with no deduction for age. Actual cash value pays the replacement cost minus depreciation, so an old roof or ten-year-old sofa is worth much less. Replacement cost coverage costs more but pays far more after a loss.
How does my deductible change my premium?
A higher deductible means you pay more out of pocket on each claim, so the insurer charges you a lower premium. Raising the deductible from $1,000 to $2,500 typically cuts the premium by about 10%, but you should only do it if you can comfortably pay the higher amount after a loss.
Why is home insurance more expensive in some areas?
Premiums are higher where claims are more common or more costly — near the coast, in wildfire or tornado zones, or in areas with high rebuilding costs. Insurers also look at local crime rates, the distance to the nearest fire station, and past weather claims in your area.
How accurate is this home insurance estimate?
It is a planning estimate based on typical rates and the factors you enter. A real quote also weighs your claims history, your credit score, the age and condition of the roof and systems, and the insurer's own pricing. Use this number to budget and compare options, then get real quotes before buying.
