Use replacement cost to rebuild, not market value
Location is the biggest rate driver
Texas has above-average home insurance rates due to storm, hurricane, or litigation risk. Actual quotes may vary significantly by ZIP code and insurer.
Standard Coverage Breakdown
Liability (Coverage E) is typically $100,000–$300,000 and Medical Payments (Coverage F) is typically $1,000–$5,000. These have minimal premium impact.

For Educational Purposes Only — Not an Insurance Quote
This calculator uses nationally-averaged rate factors to help you approximate home insurance cost and understand how variables like location, construction, and credit affect your premium. Results are estimates only and are not specific to any insurer, policy, or ZIP code.
Actual premiums vary significantly by insurer, ZIP code, coverage options, and underwriting guidelines. Wind/hail deductibles in storm-prone states may be separate from your all-peril deductible. Flood and earthquake coverage require separate policies. Credit-based insurance scores are prohibited as a rating factor in California, Maryland, Massachusetts, and Hawaii.

How to Use This Home Insurance Calculator
Property Inputs
- Home Value / Dwelling Coverage ($) — Enter the estimated replacement cost to rebuild your home from the ground up, not the market value or purchase price. For a rough estimate, multiply your home's square footage by the local cost-per-square-foot to rebuild (typically $100–$200+ depending on region and quality). Your insurer may use a replacement cost estimator tool during underwriting.
- State — Your state is the single largest geographic rating factor. States prone to hurricanes, tornadoes, hail, wildfires, or litigation (like Florida, Oklahoma, Texas, and Louisiana) have significantly higher average rates than states with mild weather and low catastrophe risk.
- Home Age — Newer homes typically cost less to insure because they meet modern building codes and have updated electrical, plumbing, and structural systems. Older homes may have outdated wiring (e.g., knob-and-tube, aluminum wiring) or galvanized plumbing that increases claim risk.
- Roof Age — The roof is one of the most frequent sources of homeowners claims. Insurers heavily weight roof age in their pricing. A newer roof (0–5 years) earns a significant discount; a roof over 20 years old may result in a surcharge or even difficulty obtaining coverage from some carriers.
- Construction Type — Masonry homes (brick, stone, concrete block) are more resistant to fire and wind than wood-frame homes, earning a lower rate. Mixed construction falls in between.
Policy & Personal Inputs
- Deductible — Your all-peril deductible is what you pay out-of-pocket before your insurance covers a claim. Choosing a higher deductible lowers your premium but increases your financial exposure after a loss. Only choose a deductible you could pay comfortably.
- Coverage Type — Replacement Cost Value (RCV) pays to rebuild or replace damaged items with new materials at current prices, with no depreciation deducted. Actual Cash Value (ACV) deducts depreciation, which can significantly reduce your payout on older components like roofs and appliances. RCV is strongly recommended for most homeowners.
- Credit Score Tier — Most states allow insurers to use a credit-based insurance score as a rating factor. Homeowners with excellent credit can pay 20–40% less than those with poor credit for otherwise identical coverage. (CA, MD, MA, and HI prohibit credit-based pricing.)
- Claims History — Prior claims — even small ones — are reported to the CLUE (Comprehensive Loss Underwriting Exchange) database and can raise your premium for 5–7 years. Insurers view frequent claimants as higher risk.
- Security & Safety Features — Toggle any applicable safety features to apply their estimated discount. Insurers verify these at policy binding, so only select features that are actually installed and active.
Home Insurance Premium Formula
Estimated Annual Premium
Annual Premium = Dwelling × Base Rate × State × Age × Construction × Roof × Deductible × Coverage × Credit × Claims × (1 − Security Discounts)- Dwelling = your entered home/replacement value
- Base Rate = $5.60 per $1,000 of dwelling (2024 national average)
- State Multiplier — e.g., FL: ×2.10, TX: ×1.75, OK: ×1.95, NV: ×0.60, ID: ×0.65
- Home Age Factor — 0–10 yrs: ×0.85 → 50+ yrs: ×1.16
- Construction Factor — Masonry: ×0.85, Mixed: ×0.92, Frame: ×1.00
- Roof Age Factor — 0–5 yrs: ×0.88 → 20+ yrs: ×1.22
- Deductible Factor — $500: ×1.10, $1,000: ×1.00, $2,000: ×0.90, $5,000: ×0.78
- Coverage Type Factor — Replacement Cost: ×1.00, ACV: ×0.87
- Credit Factor — Excellent: ×0.83, Good: ×1.00, Fair: ×1.28, Poor: ×1.55
- Claims Factor — 0 claims: ×0.94, 1 claim: ×1.18, 2+ claims: ×1.38
- Security Discount — Alarm: −6%, Smart Detectors: −3%, Deadbolt: −2%, Sprinklers: −8%, Gated: −3% (max −20%)
Standard Coverage Components
Coverage A (Dwelling) = Your entered home value
Coverage B (Other Structures) = 10% of Coverage A
Coverage C (Personal Property) = 50% of Coverage A
Coverage D (Loss of Use) = 20% of Coverage A
Coverage E (Liability) = $100,000–$300,000 (not included in premium estimate)
Coverage F (Medical Payments) = $1,000–$5,000 (not included in premium estimate)These are the standard HO-3 coverage ratios. Your actual policy may differ — some carriers offer extended replacement cost riders (125–150% of Coverage A), inflation guard, and scheduled personal property endorsements.
Frequently Asked Questions
Insurers use dozens of rating factors to determine your premium. The most influential are: the dwelling coverage amount (replacement cost to rebuild your home), your state and ZIP code (storm, wildfire, and litigation risk), the age and construction type of your home, roof age and material, your credit-based insurance score, your claims history, and your chosen deductible. This calculator applies nationally-averaged rate factors for each input so you can approximate home insurance cost and understand how each variable moves the needle.
Dwelling coverage (Coverage A) pays to rebuild your home from the ground up if it is destroyed by a covered peril — not the market value or what you paid for it. To determine the right amount, estimate your home's replacement cost: a licensed appraiser or your insurer's cost-estimator tool can provide this. A rough rule of thumb is $100–$200 per square foot depending on your region and construction quality, but this varies widely. Always insure to 100% of replacement cost to avoid a co-insurance penalty.
The most common policy is the HO-3 (Special Form). It covers your dwelling against all perils except those explicitly excluded (open perils), while personal property is covered for named perils only. Standard covered perils include fire, lightning, windstorm, hail, theft, vandalism, and water damage from burst pipes. Standard exclusions include flood, earthquake, normal wear and tear, and sewer backup. Flood and earthquake require separate policies. You can add endorsements for sewer backup, scheduled jewelry, home business equipment, and more.
Your deductible is the amount you pay out-of-pocket before insurance covers a claim. Higher deductibles significantly reduce your annual premium — going from a $500 to a $2,000 deductible can save 10–20% per year. However, you should only choose a deductible you could comfortably pay in an emergency. Note that wind/hail deductibles in coastal and storm-prone states are often separate from your all-peril deductible and are typically expressed as a percentage of your dwelling coverage (e.g., 1–5%).
In most states, insurers use a credit-based insurance score (distinct from your FICO score) as a rating factor. Studies show a statistical correlation between credit behavior and claims frequency. Homeowners with excellent credit can pay 20–40% less than those with poor credit for identical coverage. A few states — California, Maryland, Massachusetts, and Hawaii — prohibit using credit scores in home insurance pricing.
Replacement cost value (RCV) pays to repair or replace damaged property with new materials of similar kind and quality, without any deduction for depreciation. Actual cash value (ACV) pays the depreciated value — meaning a 15-year-old roof worth $5,000 today might only pay out $1,500 after depreciation. RCV policies cost more (typically 10–15% higher premium) but provide much stronger protection. Most experts recommend RCV for both dwelling and personal property coverage.
Insurers commonly offer discounts for: central station burglar and fire alarm systems (5–15% discount), deadbolt locks (2–5%), automatic fire sprinkler systems (up to 15%), smart smoke and CO detectors (3–5%), gated community (3–5%), and new home or newly renovated home discounts. Bundling your home and auto insurance with the same carrier typically provides the largest discount — often 10–25%. Ask your insurer for a full list of available discounts.
Home insurance rates reflect the risk and cost of claims in your area. Florida has the highest average premiums in the country due to hurricane exposure, litigation abuse, and reinsurance costs. Oklahoma and Kansas are expensive due to tornado and hail frequency. Texas combines hurricane coast risk, hail, and tort environment. Louisiana faces hurricane and flood risk. States with mild weather, low storm frequency, and favorable legal environments (e.g., Idaho, Nevada, Utah) tend to have the lowest premiums.
No. Standard homeowners policies specifically exclude flood damage (including storm surge) and earthquake damage. If you live in a flood zone, your mortgage lender will require a separate National Flood Insurance Program (NFIP) policy or a private flood policy. Earthquake insurance is available as a separate policy or endorsement — particularly important in California, the Pacific Northwest, and areas near active fault lines. Review your policy's exclusions carefully and purchase supplemental coverage if needed.
