Homeowners Insurance Calculator

The age factor applies in discrete bands rather than scaling smoothly with each additional year -- homes 11-20 years old all get the same 1.05x factor, so moving from 15 to 16 years stays within the same band and produces no change. The premium only shifts when you cross a band boundary, such as passing from 20 years into the 21-40 year band, or from 40 years into the 41+ year band.

In most US states, yes -- insurers commonly use a credit-based insurance score as a rating factor, on the theory that it correlates statistically with claims likelihood, and this calculator models a meaningful swing from a 15% discount above 750 to a 45% surcharge below 580. However, California, Massachusetts, and Hawaii ban the practice entirely, and a few other states restrict it, so if you live in one of those states this factor may not apply to your actual policy at all.

No -- they're estimated as fixed percentages of your Dwelling Replacement Cost (50% for contents, 10% for other structures like a detached garage or shed, and 20% for loss of use), which is a common industry default rather than a figure calculated from your actual belongings or outbuildings. If you have unusually valuable contents or extensive outbuildings, you may need higher limits than these percentages suggest, and a real policy lets you adjust each independently.

A deductible is the amount you personally pay out of pocket before insurance coverage kicks in on a claim, so a higher deductible shifts more of the small-claim risk onto you and away from the insurer. Insurers reward that reduced risk with a lower premium -- this calculator applies discounts ranging from 8% at a $1,000 deductible up to 25% at $2,500 or more, reflecting how much smaller, low-dollar claims the insurer expects to pay out.
