What Drives Your Home Insurance Premium
Homeowners insurance premiums are calculated from dozens of variables, but four factors explain the majority of the variation: your home's rebuild cost (not market value), your geographic risk for weather events, the age and condition of your roof, and your claims history. Understanding these levers helps you know what to shop for — and what changes you can make to your policy or property to lower your costs.
Rebuild cost is often misunderstood. Your insurer isn't paying what you paid for the home or what it's worth on the market — it's paying what it costs to completely reconstruct the structure at today's labor and material prices. After years of construction cost inflation, many homes are significantly underinsured, meaning a total loss payout wouldn't cover the full cost of rebuilding. Our estimator uses current per-square-foot construction cost benchmarks by state to calculate a defensible dwelling limit.
Roofs are one of the biggest pricing levers in your control. A roof replacement can cut your premium by 15–25% and may be required to keep standard coverage. In high-hail or high-wind states like Texas, Oklahoma, and Colorado, the type of roofing material (impact-resistant shingles earn additional discounts) matters as much as age.
How to Use This Estimator
- 1.Select your state. State is the single biggest driver of home insurance costs. Florida, Louisiana, Kansas, and Texas are the most expensive markets; Hawaii and Vermont are the most affordable.
- 2.Enter your home's estimated value. Use your current market value or the insured value on your existing policy. The estimator converts this to an estimated rebuild cost using regional construction cost multipliers.
- 3.Enter the year your home was built. Older homes often cost more to insure due to dated electrical (knob-and-tube, aluminum wiring), plumbing (galvanized pipes), and heating systems that increase loss frequency.
- 4.Enter your roof age. The year your roof was last replaced, not when the home was built. A 5-year-old roof on a 1970s home still earns the new-roof discount.
- 5.Review the estimated range. The result reflects what a standard HO-3 policy with $1,000 deductible would cost from a mid-tier carrier. Bundling with auto typically saves an additional 10–15%.
Understanding Your Results
- Estimated Annual Premium Range
- The low-to-high range reflects variation between carriers in your state for a standard HO-3 open-perils policy. Shopping 3–5 carriers at renewal is the single most effective way to find the bottom of that range for your specific home.
- Suggested Dwelling Coverage Amount
- This is the recommended Coverage A (dwelling) limit based on your home's estimated rebuild cost. Insuring below this amount means you may face a coinsurance penalty or coverage gap if you experience a total loss.
- Risk Tier
- States are grouped into low, moderate, high, and very high risk tiers based on historical catastrophe loss data from NOAA and ISO. A "very high" tier may mean you need a separate wind/hail or flood endorsement for complete protection.
Frequently Asked Questions
How much does homeowners insurance cost in 2026?+
The national average for homeowners insurance in 2026 is approximately $1,900–$2,300 per year for a $300,000 home. However, costs vary widely by state. Florida, Louisiana, and Texas homeowners pay $3,000–$6,000+ per year, while homeowners in Hawaii and Vermont often pay under $1,000.
What is dwelling coverage and how much do I need?+
Dwelling coverage (Coverage A) pays to rebuild your home if it's destroyed. You should insure for the full replacement cost — the cost to rebuild, not the market value. Our estimator uses current local construction cost data to calculate an appropriate dwelling limit.
Does a newer roof lower my home insurance rate?+
Yes, significantly. A roof under 10 years old typically earns a 10–20% discount. Roofs 20+ years old can trigger surcharges or make your home uninsurable with standard carriers. Some companies pay only actual cash value (depreciated) on older roofs.
Should I choose a $1,000 or $2,500 deductible?+
A $2,500 deductible instead of $1,000 typically saves 10–15% on your annual premium. The math favors a higher deductible if you have adequate emergency savings. In hail or hurricane states, wind/hail deductibles are often set as a percentage of dwelling value (1–5%), separate from your all-peril deductible.
Why is homeowners insurance so expensive right now?+
Rates have surged since 2021 due to record catastrophe losses, construction cost inflation of 20–40%, reinsurance cost increases, and insurers exiting high-risk states. Many homeowners saw 20–50% rate increases at renewal in 2024–2025. Shopping multiple carriers is more important than ever.
