A deductible is the portion of a covered loss you absorb before the insurer pays anything. Most people know that. What surprises them is that a policy can contain several different deductibles, that some are calculated as a percentage rather than a flat amount, and that which one applies depends on what caused the damage.
The fixed dollar deductible
The straightforward version. Your policy says $1,000, the covered damage is assessed at $8,000, and the insurer pays $7,000.
Two details that matter. First, the deductible applies per occurrence in most property policies, not per year — two separate covered losses in the same year each carry their own deductible. Second, it is applied to the covered amount after the insurer has determined what is covered, not to your repair bill.
The percentage deductible
This is the one that produces the unpleasant surprises, and it is now common in much of the country.
A percentage deductible is calculated against your dwelling coverage limit — the Coverage A figure on your declarations page — not against the size of the loss.
Worked example. Dwelling coverage of $400,000 with a 2% hurricane deductible means the deductible is $8,000, regardless of whether the damage is $10,000 or $200,000. On a $10,000 loss, the insurer pays $2,000. Many homeowners assume the 2% applies to the loss, which would have been $200.
Percentage deductibles typically apply to specific named perils rather than to everything, and they commonly range from 1% to 5% — higher in some coastal areas. Your ordinary all-other-perils deductible remains a flat dollar amount.
The three that most often appear separately
Hurricane deductible
Triggered by a named storm, and the trigger definition is stated in the policy. It commonly attaches when the National Hurricane Center names a storm and remains in effect through a defined period after the watch or warning ends. Because the trigger is tied to an official designation, the same wind damage can carry different deductibles depending on whether the storm was named.
Windstorm or wind/hail deductible
Applies to wind damage generally rather than only to named storms, common in areas exposed to severe thunderstorms and hail. Often a percentage.
Earthquake deductible
Earthquake coverage is normally a separate policy or endorsement, and its deductible is almost always a percentage — frequently in the range of 10% to 25% of the dwelling limit, which is substantially higher than most people expect.
Split and calendar-year deductibles
Some policies use a split deductible: one figure for most perils and a different one for a specified peril. Health insurance and some commercial policies may use a calendar-year deductible, where amounts accumulate across the year rather than resetting per event.
Health plans add further layers: separate deductibles for medical and prescription coverage, individual versus family thresholds, and an out-of-pocket maximum that is a different figure from the deductible.
Where to find yours
The declarations page lists every deductible that applies. Look for a section headed "Deductibles" and read every line, because a policy with three is not unusual.
What to note down:
- The all-other-perils deductible, usually a flat amount.
- Any percentage deductible, and which peril triggers it.
- Your Coverage A dwelling limit, since percentage deductibles are calculated from it.
- The actual dollar figure each percentage produces. Do the multiplication now and write it down.
How the deductible interacts with the settlement
Order of operations matters, and it is not always intuitive. Broadly, the insurer determines what is covered, applies any depreciation if the settlement is on an actual cash value basis, and then subtracts the deductible.
On a replacement cost policy, this is why an initial payment can look low: it is the actual cash value less the deductible, with the recoverable depreciation held back until repairs are completed and documented. That withheld amount is generally payable on proof of completion — but you have to know it exists and claim it, and there is usually a time limit.
Two situations where the deductible changes the decision
These are observations about arithmetic, not recommendations.
Small losses. When the estimated damage is close to the deductible, the net recovery may be small relative to the effect a claim can have on future premiums and on your CLUE report, which insurers consult when pricing. The calculation is yours to make with your own numbers.
Multiple losses in one year. Because property deductibles usually apply per occurrence, two storms in a season mean two deductibles. In a percentage-deductible household that can be a significant figure.
Mortgages and minimum deductibles
If your home is mortgaged, the lender may impose limits on how high a deductible you can carry, sometimes expressed as a maximum percentage of the loan or of the dwelling value. Lenders may also require specific coverage in designated flood zones. Before changing a deductible on a mortgaged property, the loan documents are the place to check.
What we are not saying
We are not telling you what deductible to carry. That depends on your savings, your risk exposure, the premium difference in your market, and your own tolerance — and we have no way of knowing any of those.
What we are saying is that a percentage deductible is calculated from your dwelling limit rather than from your loss, that many policies contain more than one deductible, and that the time to find out which applies to you is before a storm is named.
Where to verify this yourself
- Your declarations page — every deductible, the trigger for each, and your Coverage A limit.
- Your policy — the definition of the hurricane or windstorm trigger and how the deductible is applied.
- Your state Department of Insurance — state rules on percentage deductibles, which several states regulate.
- Your mortgage documents — any deductible limits imposed by the lender.
Percentage deductibles, drawn to scale
The reason percentage deductibles surprise people is that the figure is invisible until you calculate it. Here is what common percentages produce across typical dwelling limits.
| Dwelling limit | 1% | 2% | 5% | 10% |
|---|---|---|---|---|
| $250,000 | $2,500 | $5,000 | $12,500 | $25,000 |
| $400,000 | $4,000 | $8,000 | $20,000 | $40,000 |
| $650,000 | $6,500 | $13,000 | $32,500 | $65,000 |
| $900,000 | $9,000 | $18,000 | $45,000 | $90,000 |
The 10% column is not hypothetical. Earthquake coverage commonly uses percentages in that range, and a household with earthquake coverage and no idea what the deductible produces is effectively uninsured for anything short of a very large loss.
Do this now, once: find your Coverage A dwelling limit, find every percentage deductible on your declarations page, multiply, and write the dollar figures in the margin. It takes ninety seconds and it is the single most useful thing most homeowners can do with their policy documents.
What a hurricane deductible is actually triggered by
The trigger is defined in the policy and it is not simply "a big storm". Common formulations tie it to an official designation — typically the naming of a storm by the National Hurricane Center, with the deductible applying from a defined point before landfall until a defined point after the watch or warning ends.
Two consequences follow.
Identical wind damage can carry different deductibles depending on whether the storm was named. A severe unnamed thunderstorm may fall under your ordinary all-other-perils deductible or a windstorm deductible, while a named storm triggers the hurricane figure.
The window has edges. Damage occurring after the trigger period ends is generally outside the hurricane deductible even if it relates to the same weather system. This is why the date and time of damage matters, and why timestamped photographs are worth taking.
How the deductible interacts with everything else
A worked settlement, start to finish
A named storm damages a roof. Replacement cost of the roof is $28,000. The dwelling limit is $400,000 with a 2% hurricane deductible. The policy settles the roof on a replacement cost basis. The roof is eight years old with a twenty-year expected life.
| Step | Amount | Running total |
|---|---|---|
| Covered replacement cost | $28,000 | $28,000 |
| Depreciation withheld (40%) | − $11,200 | $16,800 |
| Hurricane deductible (2% of $400,000) | − $8,000 | $8,800 first payment |
| Recoverable depreciation, on proof of completion | + $11,200 | $20,000 total |
The first cheque is $8,800 against a $28,000 job, which is where most of the alarm happens. The $11,200 is recoverable — but only on proof the work was done, and only within the policy's deadline. The $8,000 is genuinely yours to fund.
Per occurrence, and what counts as one
Property deductibles generally apply per occurrence rather than per year, so two separate covered losses carry two deductibles.
What counts as a single occurrence is occasionally disputed. Two hailstorms three days apart are usually two occurrences. Damage discovered progressively from a single event is usually one. Where the answer materially affects the settlement, the definition in your policy governs, and it is worth reading rather than assuming.
Health insurance deductibles work differently
Enough people confuse the two that it is worth setting out separately.
Property and auto
- Per occurrence, in most policies
- Does not accumulate across the year
- Subtracted from the settlement
- May be a percentage of the dwelling limit
- Multiple deductibles can exist for different perils
Health
- Per calendar or plan year
- Accumulates until met, then resets
- Paid by you to providers
- Separate individual and family thresholds
- Sits alongside copays, coinsurance and an out-of-pocket maximum
On a health plan, the deductible is not the number that describes your worst year. The out-of-pocket maximum is.
Questions worth asking your insurer
Get the answers in writing
- Exactly which deductibles apply to my policy, and to which perils?
- For any percentage deductible, what dollar figure does it currently produce?
- What triggers the hurricane or windstorm deductible, and for what period?
- Do deductibles apply per occurrence or per year?
- If one event triggers two coverages, do two deductibles apply?
- What premium difference would a different deductible produce?
- Does my lender cap how high I may set it?
What we are not saying
We are not telling you what deductible to carry. What we are saying is that a percentage deductible is calculated from your dwelling limit rather than from your loss, that it comes off after depreciation rather than before, and that the ninety seconds it takes to convert every percentage on your declarations page into dollars is time better spent now than after a storm is named.
When two deductibles apply to one event
A single storm can damage the roof and a parked vehicle. Those are two policies, and each applies its own deductible — there is no combined figure.
Some insurers offer a single-deductible provision where the same event damages both a home and a vehicle insured with them, waiving or reducing the second. It is not standard, it is not automatic, and it is worth asking about when a loss touches both.
Within a single property policy, one event can also implicate two coverages: the dwelling and a detached structure, for instance. Most policies apply one deductible per occurrence rather than one per coverage, but the wording governs. Where the amounts are significant enough to matter, ask the adjuster in writing how many deductibles are being applied and on what basis.
Where a lender is involved, confirm any deductible change with them before making it. Loan agreements frequently cap how high a deductible may be set on a mortgaged property, and exceeding that cap can put you in technical breach of the loan.
