Home Insurance Calculator

How home insurance premiums are calculated

• Base rate: frame construction costs more to insure than masonry because wood burns. A typical base rate for frame homes is around 0.35% of home value per year; masonry runs about 0.25%.
• Home age: newer homes (built within 10 years) attract the lowest rates because systems like plumbing, wiring and roofing are under warranty. Older homes (30+ years) cost more due to higher replacement costs and risk of outdated systems.
• Location risk: high-risk zones (coastal hurricane areas, wildfire interface, tornado corridor) carry a 40–80% surcharge over low-risk suburban addresses.
• Deductible: raising your deductible from $500 to $2,500 typically saves 10–25% on your annual premium. The trade-off is a higher out-of-pocket cost when you file a claim.
• Coverage amount: the premium scales roughly linearly with the dwelling replacement cost. This calculator uses home value as a proxy; your actual replacement cost may differ.

Worked example

A $400,000 frame home, 15 years old, in a medium-risk suburban area, with a $1,000 deductible. Base rate: 0.35% × $400,000 = $1,400. Age factor (mid): +10% = $140. Location factor (medium): +30% = $420. Deductible factor ($1,000): −10% = −$140. Estimated annual premium: $1,820. Monthly: $152. Cost per $1,000 of coverage: $4.55.

Home insurance premium benchmarks by state

Home insurance costs vary dramatically by state due to local weather risks. The national average was approximately $1,700–$2,000 per year in 2025–2026 for a $350,000 home. Here are typical ranges by risk tier:

Ranges are estimates based on industry data through 2025–2026. Actual premiums depend on your specific property, insurer and coverage limits.

Frequently asked questions

What does homeowners insurance actually cover?

A standard HO-3 policy covers the dwelling (structure), other structures (garages, fences), personal property, loss of use (temporary housing if you cannot live in your home), personal liability, and medical payments to others. It does not cover floods or earthquakes — those require separate policies.

What deductible should I choose?

A $1,000–$2,500 deductible is the sweet spot for most homeowners: it meaningfully reduces the annual premium while leaving the deductible at a manageable out-of-pocket amount. If you have strong emergency savings, a $5,000 deductible can save 20–30% per year. Do not choose a deductible you cannot afford to pay on short notice.

Why does my actual quote differ from this estimate?

Insurance rates depend on dozens of factors this calculator does not model: claims history, credit score (in most states), specific ZIP code, roof age and type, proximity to a fire station, presence of a security system, your coverage limits, and the insurer's proprietary pricing model. Use this estimate as a sanity check on quotes, not as a replacement for them.

How often should I shop for home insurance?

Shop at renewal every 2–3 years or after any major life change (home renovation, added pool, home-based business). Loyalty discounts rarely exceed 5–10%, while switching can save 15–30%. Always compare at least three quotes and check the insurer's financial strength rating (A.M. Best A or better is preferred).

What is replacement cost vs. actual cash value coverage?

Replacement cost coverage pays to rebuild or replace your home and belongings at today's prices, without deducting for depreciation. Actual cash value (ACV) coverage deducts depreciation — a 15-year-old roof with 30% remaining life is paid at 30% of replacement cost, leaving you to fund the rest. Replacement cost policies cost 10–20% more but provide significantly better protection.
