Hazard Insurance Calculator
Hazard insurance is the dwelling portion of a homeowner's policy — covering the structure itself against covered perils. This calculator estimates premium from replacement cost, deductible, fire class, roof age, and regional rate factor.

How the math works
Homeowner hazard insurance (dwelling fire) covers the structure against fire, wind, hail, theft, and most non-excluded perils. Typical national range: $1,200–$2,400/year on a $400k home, but coastal Florida and wildfire-prone California are now $4,000–$12,000.
Fire protection class (1–10) captures the quality of local fire response — hydrant density, response time, and fire department grading. Class 1–4 (urban) gets the best rates; class 8–10 (rural, limited water) gets penalty rates. Roof age and central alarms affect pricing materially.
How to Use
- Enter dwelling coverage at REPLACEMENT COST (not market value). A mostly-land $600k home may only need $350k dwelling coverage.
- Set deductible. Higher deductibles cut premium — $2,500 vs $1,000 saves ~6% typically.
- Enter fire protection class. Check PPC (Public Protection Classification) via your insurer or ISO Mitigation.
- Adjust regional factor for coastal Florida, wildfire-prone California, etc.
- Enter roof age. New roofs discount; old roofs surcharge or get wind exclusions.
Frequently Asked Questions
What's the difference between hazard and homeowners insurance?
Hazard insurance covers the dwelling structure. Homeowners insurance (HO-3, HO-5) is a package that includes dwelling, other structures, personal property, loss of use, and liability. The mortgage lender only requires hazard coverage; homeowner buys the rest for personal protection.
Why replacement cost, not market value?
Insurance covers rebuilding the structure, not buying new land. A $800k house on a $300k lot needs only $500k dwelling coverage. Carrying more is waste; carrying less triggers coinsurance penalties on partial losses.
What are common exclusions?
Flood, earthquake, ordinary wear, intentional damage, pest damage, and (in some high-risk regions) wind/hail or wildfire. Review your policy's named perils list carefully.
How does my credit score affect premium?
In most states, insurers use insurance credit scores to set premium. Higher credit = lower premium. Some states (CA, HI, MD, MA, MI, OR, UT, WA) restrict or ban this practice.
