Home Insurance Cost Formula

This calculator starts from a national base rate per $1,000 of dwelling coverage, adjusts it by your state's average premium relative to the national average, then applies multipliers for your chosen deductible, coverage level, and recent claims history to estimate your annual premium.

Base Rate per $1,000 = National Average Annual Premium (for $400K coverage) ÷ 400
State Multiplier = State Average Premium ÷ National Average Premium
Deductible Multiplier: higher deductibles reduce premium (e.g., $500 = 1.00, $1,000 = 0.90, $2,500 = 0.78, $5,000 = 0.68)
Coverage Level Multiplier: Basic = 0.85, Standard = 1.00, Premium = 1.25
Claims Multiplier = min(1.6, 1 + Claims in Last 5 Years × 0.12)
Annual Premium = (Dwelling Coverage ÷ 1000) × Base Rate × State Multiplier × Deductible Multiplier × Coverage Multiplier × Claims Multiplier
Monthly Premium = Annual Premium ÷ 12

State averages reflect significant differences in weather risk (hurricanes, hail, wildfire, tornadoes), construction costs, and litigation environments — states like Oklahoma, Nebraska, and Kansas (tornado/hail risk) and Florida and Louisiana (hurricane risk) tend to have much higher average premiums than states like Vermont, Hawaii, and Oregon. Choosing a higher deductible lowers your premium but increases out-of-pocket costs when filing a claim, and multiple recent claims typically increase premiums at renewal.

How to Use the Home Insurance Cost Estimator

1

Select your state

Choose the state where the home is located, since regional weather risk and construction costs significantly affect average premiums.

2

Enter your dwelling coverage amount

This is the amount of coverage for rebuilding the structure of your home (Coverage A), typically based on replacement cost, not market value.

3

Choose your deductible

Select from common deductible amounts ($500, $1,000, $2,500, $5,000) — higher deductibles generally lower your premium.

4

Choose your coverage level

Select Basic, Standard, or Premium to reflect the breadth of coverage and limits for personal property, liability, and additional living expenses.

5

Enter claims in the last 5 years

Add the number of homeowners insurance claims filed in the past 5 years, which can increase your premium.

6

Click Calculate

View your estimated annual and monthly homeowners insurance premium.
