To lower home insurance costs, keep the dwelling limit at rebuild cost, raise the deductible when the saving beats the expected cost, read any hurricane percentage deductible in dollars, and claim mitigation discounts. On 2019-2023 claim rates, going from $1,000 to $2,500 costs at most $82.95 a year.
To lower home insurance costs, cut the price per dollar of cover, never the cover itself. Keep the dwelling limit at what it would cost to rebuild, then raise the all-perils deductible where the yearly saving beats what the bigger deductible is expected to cost, claim every mitigation and bundling discount in writing, and re-quote before renewal.
There is a second deductible many owners never read. In hurricane and hail country the wind deductible is often a percentage of the dwelling limit, and on an ordinary house it can run to five figures. The math on both is below, using real claim rates rather than rules of thumb.
| Lever | What to do | What the data says |
|---|---|---|
| All-perils deductible | Price $1,000, $2,500 and $5,000 | $1,000 to $2,500 costs at most $82.95 a year in expected claims |
| Wind or hurricane deductible | Read it in dollars, not percent | 2% of a $400,000 limit is $8,000 |
| Mitigation discounts | Document the roof, openings and defensible space | Florida rate filings must include them; California FAIR Plan offers 12 |
| Small claims | Pay small losses yourself | About one property claim per 18.1 insured home-years |
| Re-quote | Same limits, three or more insurers, 45 days before renewal | Spending rose 31.2% in 2025 alone (BLS) |
Before you start: six papers and one estimate
Pull the declarations page, which lists Coverage A (the house), B (other structures), C (belongings), D (living costs while you are out of the house), liability, and every deductible. Then the renewal notice with the new premium, so you have the number to beat.
Next, a rebuild-cost estimate for the house itself, not its sale price; your insurer’s own figure on the declarations page is a starting point. Make a list of the home’s upgrades: roof age and type, storm shutters or impact glass, newer wiring and plumbing, alarms and water-leak sensors. Count the cash you could pay toward a deductible this week, and if you have a mortgage, find the escrow statement, because the lender pays the premium from it and often sets the largest deductible it will accept.
The steps: from renewal notice to a cheaper policy
1. Start 45 days before the policy renews.
Some insurers ask for an inspection or roof photos before they will quote, which takes time.
2. Check that Coverage A equals your rebuild-cost estimate.
If it is lower, raise it before you shop; a cheap quote on too little cover fails at the worst moment.
3. Write down each deductible in dollars, including any wind or hurricane percentage.
Multiply the percentage by Coverage A, so that 2% of $400,000 reads as $8,000.
4. Price the all-perils deductible at $1,000, $2,500 and $5,000.
Compare each yearly saving with the expected cost in the worked example below.
5. Send the insurer proof of every mitigation feature you have.
A wind-mitigation inspection form, roof permit dates, shutter receipts or a defensible-space record.
6. Get quotes from at least three insurers on the same limits.
Ask each for bundling, claims-free, new-roof, alarm and paid-in-full discounts by name, in writing.
7. Tell your mortgage servicer before switching, and keep the old policy until the new one starts.
The servicer pays from escrow, so it needs the new declarations page to avoid paying both.
A worked example: three deductibles and a hurricane clause
The all-perils deductible. ISO’s homeowners figures, published by the Insurance Information Institute, average 5.53 property damage claims per 100 insured homes a year over 2019-2023 (HO-2, HO-3 and HO-5 policies, excluding Alaska and Texas). A higher deductible adds at most the difference to a claim, so its expected yearly cost is the claim rate times that difference:
| Deductible change | Extra you pay on a claim, at most | Expected extra a year |
|---|---|---|
| $1,000 to $2,500 | $1,500 | $82.95 |
| $1,000 to $5,000 | $4,000 | $221.20 |
| $2,500 to $5,000 | $2,500 | $138.25 |
If a quote cuts the premium by more than $82.95 when you move from $1,000 to $2,500, the higher deductible wins on average; at 5.53 claims per 100 homes, the average home files a property claim about once every 18.1 years. Those are upper bounds, because a loss between the two deductibles costs you less than the full difference.
The hurricane clause. Florida law (s. 627.701) makes insurers offer hurricane deductibles of $500, 2%, 5% and 10% of the dwelling limit, and lets them skip the $500 option on homes insured for $250,000 or more. On a $400,000 dwelling limit those choices are:
- 2%: $8,000
- 5%: $20,000
- 10%: $40,000
ISO’s average wind and hail claim payment over 2019-2023 was $14,747, counted as the insurer’s loss after the deductible. An $8,000 deductible is 54.2% of that figure, so on a storm repair of that size the owner would carry roughly half the bill instead of a small slice. Pick the percentage with the cash in your emergency fund in view, not only the premium.
Discounts the law writes in: wind and wildfire mitigation
Two states have put mitigation discounts into statute or regulation, which makes them worth asking for by name.
Florida. Under s. 627.0629, a residential rate filing must include actuarially reasonable discounts, credits or deductible reductions for features shown to cut windstorm losses, including roof strength, roof covering, roof-to-wall connections and opening protection. The same section requires the premium notice to show the hurricane premium separately from everything else, so you can see what share of your bill the wind risk drives.
California. The Department of Insurance’s Safer from Wildfires rules give a discount for each listed mitigation action. The California FAIR Plan, the state’s insurer of last resort, offers up to 12 wildfire hardening discounts on policies effective on or after November 15, 2025: clearing the 5 feet around the house, a Class A fire-rated roof, enclosed eaves, ember-resistant vents, and community programs such as Firewise USA sites. Taking all 12 can cut the wildfire portion of a dwelling policy by up to 16.4%.
The original data: what homeowners pay, and where the market went
Spending since 2016. In the Consumer Expenditure Survey, homeowner households reported spending $681 on homeowners insurance in 2016 and $1,473 in 2025, a rise of 116.3%. Most of it came late: the 2025 figure was 31.2% above 2024. Their average pre-tax income rose 42.3% over the same nine years, so the bill went from 0.74% of income to 1.12%.
Year by year from 2016 the figure ran $681, $697, $729, $758, $806, $837, $919, $972, $1,123 and $1,473. Owners with a mortgage reported $1,498 and owners without one $1,441 in 2025. The survey figure is an average over every homeowner household, and it runs below the NAIC’s per-policy average premium of $1,569 for 2022, the latest year the NAIC has published; the trend is the point.
Where the risk is. The Treasury’s Federal Insurance Office studied ZIP Code data from insurers for 2018-2022. It found premiums per policy rose 8.7% faster than inflation, that homeowners in the fifth of ZIP Codes with the highest expected climate-related losses paid $2,321 on average, 82% more than the lowest-risk fifth, and that their nonrenewal rates ran about 80% higher.
The insurer of last resort. When private insurers pull back, homeowners land in a state plan. On each September 30 we read the policy count at Florida’s Citizens Property Insurance and the California FAIR Plan. Citizens grew from 708,919 policies in 2021 to 1,407,805 in 2023, then fell to 254,836 in 2026, down 81.9%. The FAIR Plan rose from 273,346 policies in 2022 to 686,376 in 2026, up 151.1%, by its five-year county report; its summary page puts the September 2026 count at 698,307, and the county report itself notes that totals vary by report.
For a homeowner the two lines say different things. The FAIR Plan calls itself a temporary safety net, and its own discount flyer says brokers may be able to offer more comprehensive coverage than it does, so a California owner placed there should keep asking private insurers at each renewal. A Florida owner offered a move from Citizens to a private insurer is being offered a different contract, and its deductibles and exclusions deserve the same read as its price.

How to tell it worked: four checks before you sign
Coverage A did not fall. The new dwelling limit is at or above your rebuild-cost estimate, and the policy pays replacement cost, not actual cash value, on the house.
Every deductible is written in dollars, the wind or hurricane one included, and each is no larger than the cash you hold.
The saving clears the expected cost. For a deductible move, the yearly premium cut beats the expected extra in the table above, for example $82.95 for $1,000 to $2,500.
The discounts are on the declarations page, line by line, and the next renewal date sits in your calendar 45 days ahead so the review repeats every 12 months.
When it fails: where a lower premium costs more
Cutting Coverage A. Lowering the dwelling limit lowers the premium and leaves you short after a total loss, when rebuilding costs are highest.
Assuming flood is covered. FEMA’s FloodSmart notes that most homeowners insurance does not cover flood damage, and that 99% of US counties have had a flood event in the past 20 years. Dropping a flood policy to save money removes the one cover the home policy does not replace.
Claiming small losses. A string of small claims can cost a claims-free discount or a renewal. At about one claim per 18 years for the average home, a $1,200 repair on a $1,000 deductible would pay only $200 and still go on your record.
Switching on price alone. A cheaper quote can carry a higher wind deductible, an actual-cash-value roof clause or a water-damage cap. Compare the declarations pages line by line, not the premiums.
Questions homeowners ask about the bill
Why is my home insurance going up so much?
Claim costs and catastrophe losses have risen. ISO’s average property damage claim was $16,857 over 2019-2023, and the Treasury found premiums rising faster than inflation in 2018-2022, most in the highest-risk ZIP Codes. Your own price also moves with your roof age, claims and the insurer’s filing.
Is a $2,500 deductible worth it on home insurance?
On 2019-2023 claim rates it is when moving from $1,000 to $2,500 saves more than about $82.95 a year and you can pay $2,500 from savings without borrowing.
Does paying off the mortgage lower home insurance?
Not by itself: the premium is priced on the house, not the loan. What changes is that the lender’s requirements go away, so the deductible is yours to choose. Keep the cover; the house is still the asset at risk. The mortgage payment calculator shows how much of a monthly payment is principal and interest, and the escrow on top of it is taxes and insurance.
What is a wind mitigation inspection?
It is a report by a licensed inspector on the roof, its attachment and the opening protection, which a Florida insurer uses to apply the discounts s. 627.0629 requires.

A bigger deductible is a saving only with the cash behind it, which is what an emergency fund holds. Insurance sits inside the escrow part of a mortgage payment, which the mortgage payment calculator helps you split out. If a lower rate is also on the table, refinancing a mortgage shows the break-even math, and inflation explains why rebuild costs, and so Coverage A, climb every year.
