Parametric insurance for homeowners: how it works and its limits
Parametric policies pay a fixed sum when a measured trigger, like earthquake shaking at your address, is hit, whatever your damage. What exists and its limits.
A parametric policy pays a fixed amount when a measured event, such as earthquake shaking at a set intensity near your address, crosses a trigger written into the contract. It does not look at your damage. That makes payment fast and makes it a poor substitute for the policy that rebuilds your house, so in the U.S. it is a small add-on, sold in a few places, used mainly to cover a big deductible or the first weeks of living costs. If you are weighing one, the questions that matter are where the trigger is measured, how much it pays, and who stands behind the promise.
How a parametric policy works
The NAIC's overview of parametric disaster insurance breaks every parametric contract into three pieces:
- A trigger. A measurable parameter, such as earthquake magnitude, wind speed or flood extent, defined in the contract.
- A payout. A fixed sum stated in the contract.
- A verifier. A third party, usually a government agency, that confirms the trigger was met. Policies often name a backup source.
Your homeowners policy works differently. It is an indemnity contract: an adjuster inspects the damage, applies the deductible and limits, and pays the loss. The two approaches line up like this.
| Homeowners (indemnity) | Parametric | |
|---|---|---|
| What sets the payment | Your actual covered damage, less the deductible | A preset amount once the trigger is met |
| Who investigates | Adjuster, contractor estimates, proof of loss | An outside data source; no loss inspection |
| Speed | Weeks to months | The National Conference of State Legislatures says claims typically resolve in about 30 days; sellers advertise days |
| Pays the cost to rebuild | Yes, up to limits | No; the amount is usually small |
| Can pay when you have no damage | No | Yes |
| Can pay nothing when you do have damage | Only if excluded or under the deductible | Yes, if the trigger is not met |
| Counts toward lender-required coverage | Yes, if it meets the loan's requirements | Generally no |
That last row is a practical point. Fannie Mae and Freddie Mac require the dwelling to be insured on a replacement-cost basis, and flood requirements for federally regulated loans are written around policies that pay for building damage. A fixed-sum payout does not satisfy either, so a parametric policy is something you buy on top of required coverage, never in its place.
What is available to U.S. homeowners
The market is thin, and it changes. As of October 2026, here is what this guide could verify.
Earthquake: Jumpstart. Jumpstart began selling parametric earthquake policies to California homeowners, renters and small businesses in 2019, adding Oregon and Washington in late 2020, and Neptune Flood bought the company in October 2021 (Insurance Journal; see Neptune Flood). The National Conference of State Legislatures, in a January 2025 article, described Jumpstart as paying up to $10,000 to homeowners and $20,000 to small businesses, with monthly premiums as low as $8. Jumpstart's own materials describe payment based on U.S. Geological Survey shaking data, and its payout-eligibility explanation says a California address qualifies when the USGS ShakeMap codes it as severe shaking, a peak ground velocity of 30 centimeters per second or more, using data available 24 hours after the quake. The company's website now redirects to Neptune Flood's, so confirm that the product is currently on sale in your state and read the current terms before assuming any of this applies. Jumpstart's founder said at the time of the sale that the product is not a substitute for coverage from the California Earthquake Authority and that customers could hold both; see The California Earthquake Authority explained and earthquake insurance explained for the conventional policy.
Flood: community pilots, not individual policies. In March 2023 New York City announced a one-year pilot of a policy insured by Swiss Re Corporate Solutions. If satellite imagery from ICEYE showed that flooding covered more than a set share of an insured neighborhood, Swiss Re would pay the Center for NYC Neighborhoods, which would distribute grants of up to $15,000 to qualifying households, with up to $1.1 million available (Insurance Journal). Households applied for grants; they did not buy a policy. The structure shows a model in which a city or nonprofit holds the parametric cover and passes the money on, which can reach more people than selling to individuals.
Hurricane: concept more than product. A hurricane parametric policy would typically pay when a storm of a stated category or wind speed passes within a set distance of your address, and is usually pitched as a way to fund a hurricane deductible. This guide did not find a current, widely available product of this kind aimed at individual homeowners. If an agent offers one, treat the questions below as a minimum.
Puerto Rico has a rule. The NAIC notes that Puerto Rico's Rule No. 103 (2020) sets specific requirements for personal lines parametric products; few jurisdictions have anything similar, so these products otherwise fall under general insurance law. Some state officials, NCSL reports, worry they may fall outside existing insurance statutes, and a Maryland bill that would have created a framework and a pilot (SB 95 of the 2026 session) shows no action beyond a Senate committee hearing on the legislature's bill page, last updated June 30, 2026.
Basis risk: the whole trade-off
The gap between what a parametric policy pays and what you lose is called basis risk. The NAIC calls it the main downside: losses "could differ by any margin" from the coverage amount, and losses can occur without the trigger being met.
Say a policy pays $10,000 if peak ground velocity at your address reaches 30 cm/s. Hypothetically:
| Your house | Damage | Parametric payment |
|---|---|---|
| Heavy shaking at 31 cm/s, cracked foundation | $90,000 | $10,000 |
| Shaking at 28 cm/s, chimney falls and plumbing breaks | $35,000 | $0 |
| Shaking at 32 cm/s, nothing broken | $0 | $10,000 |
All three behave as the contract says. The second owner is the one who is unhappy, and the third is the one who is pleasantly surprised. A tighter trigger lowers the odds of a miss but raises the price.
Where it earns its keep: the deductible gap
Percentage deductibles make a payout that ignores your damage genuinely useful. California Earthquake Authority policies carry deductibles of 5%, 10%, 15%, 20% or 25% of the dwelling limit (CEA). Say your dwelling limit is $500,000 and you chose 15%: that is $75,000 you absorb before the policy pays, and if the quake does $60,000 of damage, you collect nothing. A $10,000 parametric payment arrives in days regardless and pays for the hotel, the deposit on a contractor, the temporary storage unit. A 2% hurricane deductible on a $400,000 dwelling is $8,000, the same logic on a smaller scale; see earthquake deductibles: why they're so high and the hurricane and percentage deductible calculator.
It also reaches people who have no earthquake coverage. California's statewide earthquake take-up was 15.24% of homeowners policies in 2025, according to the CEA's annual report to the Legislature, so most California homeowners carry no earthquake coverage at all. A small parametric policy is better than nothing, but it is not a replacement for what FEMA disaster assistance vs insurance: what each pays describes as a very limited federal safety net.
The honest case on each side
Supporters point to speed, simplicity and cost. A policy that pays within days without an adjuster, priced from a ZIP Code and not a building inspection, can put cash in hand when displaced households need it most, and it can be offered where traditional earthquake or flood cover is unavailable or priced out of reach. The NAIC adds that fixed payouts and independent verification reduce fraud and that the insured still has an incentive to limit losses.
Skeptics point to the small amounts, the basis risk and the regulatory gaps. Payouts of $10,000 or $15,000 do not replace a $400,000 house. Many of these products are written in the surplus lines market, where state guaranty funds usually do not apply (surplus lines home insurance when standard carriers say no), and where an insurtech's model may be young (insurtech home insurers: what they changed). The NAIC notes that policies usually name a backup data source in case the main agency cannot issue a reading, which is a detail worth checking. Treat the premium as the price of a small, fast lump sum, not as discounted insurance.
Questions to ask before you buy
- Who is the insurer, and how is it licensed? Admitted or surplus lines, and whether a guaranty fund would apply.
- What exactly is the trigger? The measure, the source, whether it is measured at your address or at a distant station, and when the reading is taken.
- How much is paid, how often? One payment per event or per policy term, and what happens with aftershocks or repeat storms.
- Do you need to prove anything? Some policies pay on the trigger alone and others ask you to confirm expenses. Get the answer in writing.
- How does it interact with your other policies? Ask your homeowners or earthquake insurer whether a parametric payment reduces your claim. It should not for an indemnity insurer, but confirm.
- What happens at renewal? Price changes after an event, cancellation terms and whether the product is still offered in your state.
- Taxes. Ask a tax adviser how the payment is treated.
Key takeaways
- A parametric policy pays a preset amount when a measured trigger is hit; it does not pay for your actual damage, and it does not satisfy lender insurance requirements.
- The U.S. market for individual homeowners is small. The clearest example is Jumpstart's earthquake product, now owned by Neptune Flood, which has offered fixed payments of up to $10,000 to homeowners; confirm current availability.
- Basis risk is the main limit: you can have a loss and no payout, or a payout and no loss.
- Its best use is covering a percentage deductible or early living costs, as a supplement to standard homeowners, earthquake or flood insurance.
- Ask who the insurer is, what exactly triggers payment and how it coordinates with your other policies before you buy.
