California Home Insurance Calculator
A budgeting estimate for a full California homeowners policy — the kind that covers fire, water, theft, liability and loss of use. Everything runs in your browser; nothing is sent anywhere, and there's no form to fill in.
This estimates a standard homeowners policy, not FAIR Plan fire-only coverage. If you've been non-renewed and are pricing the FAIR Plan, use the FAIR Plan premium calculator instead — it models a different product.
It is a modeled range, not a quote. It scales published California average premiums by your rebuild cost and a self-assessed wildfire risk tier. It cannot see your parcel, so it cannot price it. The full methodology is below the tool.
Estimate your annual range
Enter your rebuild cost — not market value, not purchase price. Everything else adjusts from there.
- Base band. Lower-risk California homes are modeled at $380–$560 per $100,000 of dwelling coverage per year. That band is anchored to published statewide averages, which cluster between roughly $1,400 and $1,900 a year at $300,000–$350,000 of dwelling coverage depending on the source's assumptions.
- Wildfire multiplier. Moderate exposure applies 1.6×–2.4×; high exposure applies 3.0×–5.0×. The high band reflects reporting that ZIP codes near high fire-risk zones can pay three to five times more than low-risk inland communities.
- Deductible and mitigation adjustments are modeled, not sourced. Deductible credits of 8%, 15% and 22% at $2,500, $5,000 and $10,000, and a 10% mitigation credit, are conventional rule-of-thumb magnitudes used here for illustration. Actual credits are set by each insurer's filed rates and vary considerably. California's Safer from Wildfires regulation requires admitted insurers to reflect specified mitigation in rating, but it does not fix the amount.
- Large-home taper. Above $1,000,000 of coverage the per-$100k rate is tapered, because premium does not scale linearly with dwelling limit at the top of the market.
- What it excludes. Any separate wildfire deductible, surplus-lines taxes and fees, earthquake or flood coverage, scheduled personal property, and any insurer-specific supplemental fee.
What to put in each field
Dwelling coverage — the number people get wrong
Enter the cost to rebuild the structure at today's labour and materials prices. This is routinely very different from market value: a home selling for $1.8M in a desirable area might rebuild for $900K, while a remote custom build can rebuild for more than it would ever sell for. Land value is not insured, because land does not burn.
If you don't know it, a contractor's square-foot estimate for your construction type is the usual starting point. Getting this wrong in the low direction is the most common reason homeowners come up short after a total loss; wrong in the high direction means paying for coverage you cannot use.
Wildfire exposure — be honest
Check your parcel against CAL FIRE's Fire Hazard Severity Zone maps rather than guessing. Proximity to open space, slope, and whether you sit in a wildland-urban interface area all matter. Choosing a tier below your actual exposure produces a comfortable number and a useless one.
Deductible
The figure that applies to an ordinary claim. The critical thing this tool cannot model: many California policies in high-risk areas now carry a separate, higher wildfire deductible, sometimes as a percentage of the dwelling limit. A 2% wildfire deductible on a $900,000 limit is $18,000 — a very different number from the $1,000 on the declarations page. Always ask.
Mitigation
Tick this only if the work is documented — dated photographs, receipts, inspection reports. Underwriters cannot credit work they have no record of, which is why documentation is worth more than the work alone.
What this tool cannot do
Stated plainly, because an estimate presented with false confidence is worse than no estimate.
- It is not a quote. It is not a binder, not an offer of coverage, and no insurer is bound by it. Only a licensed carrier or broker can give you a bindable price.
- It does not use insurer rate data. No carrier's filed rates are used. It scales published market averages, which is a different and much blunter thing.
- It cannot see your parcel — not your exact hazard zone, protection class, roof material, vent type, claims history or distance to a hydrant. Those are precisely the variables that decide your real premium.
- It cannot tell you whether anyone will write you. In much of California availability, not price, is the binding constraint. A low estimate means nothing if no admitted carrier will quote your address.
- Deductible and mitigation credits are illustrative. They are modeled magnitudes, not sourced figures. Real credits come from each insurer's filed rates.
- It models a standard homeowners policy only. Not FAIR Plan coverage, not surplus lines, not DIC.
From estimate to actual coverage
Calculator questions
How accurate is this California home insurance calculator?
It produces a modeled budgeting range, not a prediction of your premium. It scales published statewide averages by rebuild cost and a self-assessed wildfire tier, so it is most reliable for lower-risk properties near the statewide norm and least reliable at the extremes, where individual property characteristics dominate. Treat it as a starting range to sanity-check quotes against.
Is this a home insurance quote?
No. It is an estimate produced entirely in your browser from published averages. It is not a quote, a binder or an offer of coverage, no insurer has seen your details, and nothing you enter is transmitted anywhere. Only a licensed carrier or broker can give you a bindable price.
Should I enter my home’s market value in the calculator?
No — enter the estimated cost to rebuild the structure. Market value includes land, location and demand, none of which are insured. The two figures can differ by hundreds of thousands of dollars in either direction.
Why is the estimated range so wide?
Because California premiums genuinely are. Wildfire exposure, protection class, roof construction and claims history can move the same dwelling limit by a factor of ten. A narrow range would be a more confident-looking estimate and a less honest one.
Does this calculator include the California FAIR Plan?
No. This models a standard homeowners policy covering fire, water, theft, liability and loss of use. The FAIR Plan is fire-only and priced differently, and most FAIR Plan policyholders also need a separate DIC policy. Use the FAIR Plan calculator for that.
Is my data stored or sent anywhere?
No. The calculation runs entirely in your browser in JavaScript. There is no form, no submission, no storage and no transmission of anything you select.
