Home Insurance Calculator

Estimate your annual homeowners insurance premium based on home value, construction, roof type, state, and deductible.

How This Calculator Works

  1. Tell us about your home: Home value, construction type, roof material, age, and square footage are the core rating factors insurers use.
  2. Add location & features: Your state, proximity to a fire station, pool/trampoline presence, and security system all shift your rate up or down.
  3. Get your annual estimate: We apply 0.5% of your home value as a base rate, then multiply by every risk factor to produce a realistic annual range.

Estimate Formula

Annual Premium   =  Home Value x 0.5% (base rate)
                  x  Year built         (Pre-1970: 1.30 / 2010+: 0.90)
                  x  Roof type          (Slate: 0.85 - Flat/Other: 1.15)
                  x  Construction       (Stone: 0.90 - Wood Frame: 1.10)
                  x  Square footage     (Under 1,000: 0.80 - Over 3,500: 1.35)
                  x  Fire station dist. (Under 1 mi: 0.90 - Over 5 mi: 1.20)
                  x  Pool/trampoline    (+8% if Yes)
                  x  Security system    (-5% if Yes)
                  x  Deductible         ($500: 1.10 - $5,000: 0.78)
                  x  State multiplier   (FL: 1.90 / LA: 1.80 / TX: 1.50 / most: 1.0)

Range = Estimate x 0.82  to  Estimate x 1.18

Key Factors That Affect Your Estimate

What Affects Home Insurance Rates?

  • Home Age & Construction: Older homes and wood-frame construction typically cost more to insure due to higher fire and repair risks.
  • Location: State regulations, proximity to fire stations, and local disaster risk zones heavily influence rates.
  • Coverage Choices: Higher dwelling coverage limits, lower deductibles, and optional add-ons increase your premiums.
  • Home Features: Monitored security systems, newer roofs, and storm shutters can qualify you for substantial discounts.

Frequently Asked Questions

What does homeowners insurance cover?

Standard policies (HO-3) cover your dwelling, personal property, liability, and additional living expenses if you can't live in your home after a covered event. Floods and earthquakes are typically NOT covered.

How much homeowners insurance do I need?

You need at least enough dwelling coverage to fully rebuild your home at current construction costs. Personal property coverage is typically 50-70% of dwelling coverage.

Is homeowners insurance required?

It's not legally required by state law, but virtually all mortgage lenders require it as a condition of your loan.

Why is home insurance so expensive in Florida?

Florida faces high hurricane risk and severe litigation rates, making it the most expensive state for homeowners insurance.

How can I lower my homeowners insurance premium?

Bundle with your auto insurance, install a security system, raise your deductible, update your roof, and shop quotes every 2-3 years.

The Inputs, Field by Field

Home value and rebuild cost. Homeowners insurance is priced on the cost to rebuild, not the market price or land value. Enter your dwelling's replacement cost, which can differ substantially from what you paid.

Location and construction. Your state, local catastrophe risk (wind, hail, wildfire), and the home's age and construction type drive the premium. Older roofs and homes in high-risk zones estimate higher.

Coverage and deductible. Higher dwelling and liability limits raise the premium; a higher deductible lowers it. The estimate reflects the trade-off between monthly cost and out-of-pocket risk at claim time.

How to Read Your Estimate

The monthly range reflects how widely home insurance is priced by region and property. The low end suits a newer, low-risk home with a higher deductible; the high end reflects older construction, catastrophe exposure, or richer coverage. Because a single large claim can dwarf years of premium, weigh the deductible against what you could comfortably pay after a loss, not just the monthly saving.

Assumptions and Limitations

This is an educational estimate, not a quote or a binder of coverage. It does not price flood or earthquake, which require separate policies, and it cannot see carrier-specific discounts, roof-age rules, or claims history. Replacement-cost estimates here are a starting point; a professional rebuild-cost estimate is more precise. Compare real quotes from licensed insurers before buying.

More Frequently Asked Questions

Does home insurance cover flooding?

No. Standard home insurance excludes flood damage, which requires a separate policy through the National Flood Insurance Program or a private flood insurer. Earthquake coverage is also typically separate.

What is replacement cost versus market value?

Replacement cost is what it takes to rebuild your home; market value includes land and location. Your dwelling coverage should track replacement cost, which is often different from your purchase price.

How can I lower my home insurance premium?

Raising your deductible, improving your roof, bundling with auto, and maintaining good credit where allowed can all reduce your premium. Shop quotes every year or two.
