Raising a deductible lowers the premium and raises what you pay when something happens. This works out the break-even: how many years without a claim it takes for the savings to cover the additional exposure.
You need two written quotes from your insurer for the same coverage at two different deductibles. Estimating the premiums makes the result meaningless, because the saving is the whole calculation.
What the result means
The break-even is how long you would need to go without a claim before the premium savings cover the extra $ you would pay on that claim. Beyond that point the higher deductible has been worth it; before it, it has not.
Two things the number does not capture. Claims are not evenly spaced — two storms in one season means two deductibles in one year. And a higher deductible discourages small claims, which has its own value because claims affect your record and your future pricing.
Before changing anything
- Could you pay the higher deductible tomorrow? If not, the saving is not a saving.
- Does your lender cap it? Many do on mortgaged property.
- Is there a separate wind or hail deductible? If it is a percentage of your dwelling limit, run that one separately — it is often the one that actually applies.
How to choose a deductible, properly
The calculator above answers the arithmetic. The arithmetic is only part of the decision, and the rest of this page is the part that actually determines whether a higher deductible is right for your household.
Start by finding what you actually have
More people get this wrong than expect to, because most policies carry more than one deductible and only some of them are stated as a dollar figure.
On your declarations page, find every one
- The all-other-perils deductible — the flat figure that applies to most property claims
- Any wind or hail deductible, which is frequently a percentage
- Any hurricane or named storm deductible, also frequently a percentage
- Any earthquake deductible, where you carry that coverage — commonly a high percentage
- Collision and comprehensive deductibles on each vehicle, which need not match each other
- Any endorsement with its own deductible, such as water backup or service line
Convert every percentage into dollars before you do anything else. A 2% hurricane deductible on a $400,000 dwelling limit is $8,000. On a $650,000 limit it is $13,000. The percentage stays the same while the dollar figure rises every year with your inflation guard, and almost nobody recalculates it.
The order of operations, which changes the answer
A deductible is not subtracted from your repair bill. It is subtracted at the end of a sequence, and understanding that sequence explains why settlements arrive smaller than people expect.
- The insurer determines what is covered. Exclusions are applied here, not later.
- The covered loss is valued, usually at replacement cost.
- Depreciation is applied where the settlement basis is actual cash value, or withheld as recoverable depreciation on a replacement cost policy.
- The deductible is subtracted from what remains.
Worked through: a $28,000 roof, eight years into a twenty-year life, on a policy with a 2% hurricane deductible and a $400,000 dwelling limit. Replacement cost $28,000, less 40% depreciation withheld leaves $16,800, less the $8,000 deductible leaves a first payment of $8,800. The $11,200 comes back on proof the work was done. The $8,000 is yours permanently.
The three questions the calculator cannot answer
-
First
Could you pay it tomorrow?
Not over six months, and not on a card carried at interest. Tomorrow, alongside whatever else the loss costs you. If the honest answer is no, the break-even period is irrelevant — you would be choosing to be underinsured at the moment coverage matters most.
-
Second
Where will the saving actually go?
The arithmetic assumes the annual saving is available when a claim arrives. For most households it simply blends into ordinary spending. The version that works is moving the difference into a separate account each year and leaving it there.
-
Third
What is your realistic exposure?
Nobody knows their own future, but circumstances differ. A household in a hail-prone area with an ageing roof is not in the same position as one that has not claimed in twenty years.
The pattern to look for in the numbers
When you get quotes at several levels, a pattern usually emerges: the first increase offers the best ratio, and each subsequent step buys proportionally less.
| Deductible | Annual premium | Saving | Extra exposure | Break-even |
|---|---|---|---|---|
| $500 | $1,840 | — | — | — |
| $1,000 | $1,690 | $150 | $500 | 3.3 years |
| $2,500 | $1,480 | $360 | $2,000 | 5.6 years |
| $5,000 | $1,310 | $530 | $4,500 | 8.5 years |
Those figures are constructed to show the shape rather than to predict yours. What matters is that the table is buildable with one phone call, and that the largest jump is frequently not the best value.
Where the calculation works differently
| Situation | What changes |
|---|---|
| Health insurance | The deductible accumulates across a plan year rather than applying per event, and sits alongside an out-of-pocket maximum. That maximum, not the deductible, describes a bad year |
| Percentage deductibles | Rise automatically as the dwelling limit rises. Recalculate every renewal |
| Comprehensive versus collision | Separate deductibles that need not match. Comprehensive losses — theft, hail, glass — are less controllable |
| Financed property or vehicles | The lender may cap how high the deductible can be set. Exceeding it can breach the loan |
| One event, two policies | A storm damaging a house and a car triggers two deductibles unless a single-deductible provision applies |
The second benefit people miss
A higher deductible means small losses fall below it and never become claims. That is not only a cost.
Claims affect future pricing, and on property policies they can affect eligibility as well. A household that absorbs a small loss rather than claiming it keeps a cleaner record, and a claims-free history is itself worth money.
This is not a reason to choose a deductible you cannot fund. It is a reason to notice the trade has a second dimension the premium comparison does not show.
Where a lower deductible is the right answer
This page is framed around raising one, because that is the direction people are usually pushed. The reverse is legitimate.
Reasons households lower a deductible
- Savings were depleted and the current figure is no longer fundable
- Circumstances changed — an ageing roof, a move to a hail-prone area
- The premium difference turned out to be small, making the extra exposure poor value
- Peace of mind, which is a legitimate thing to buy
That last point deserves stating plainly. Insurance exists to convert an unpredictable large loss into a predictable small cost. Someone who sleeps better with a lower deductible is buying exactly what insurance is for, and the arithmetic does not have to win the argument.
The checklist
Before changing anything
- Get quotes at two or three levels, in writing
- Run each through the calculator above
- Convert any percentage deductible into a dollar figure at this year's limit
- Confirm you could fund the higher figure immediately
- Check whether a lender caps it
- Decide where the annual saving will actually be held
- Confirm the change appears on the revised declarations page
What we are not saying
We are not telling you what deductible to carry, and we do not sell insurance or receive anything from any insurer. The calculator does arithmetic with numbers you supply; it does not know your circumstances.
What we are saying is that the calculation is impossible without your insurer's actual figures, that the ability to fund the higher amount tomorrow overrides everything else, that percentage deductibles rise silently every year, and that the saving only counts if you genuinely set it aside.
How the premium difference is actually set
It helps to understand why raising a deductible saves anything at all, because it explains why the saving is smaller than people expect at the higher levels.
Most claims are small. Raising a deductible from $500 to $1,000 removes the insurer's exposure to a large number of modest claims, which is genuinely valuable to them — hence a meaningful discount. Raising it from $2,500 to $5,000 removes exposure to relatively few additional claims, because losses in that range are much less frequent.
The consequence is the pattern in the table above: each step buys less than the one before. It also explains why the ratio differs so much between insurers — each has its own claims data and its own view of how frequent losses in each band are.
Percentage deductibles deserve their own calculation
The calculator handles flat figures. Percentage deductibles require one extra step, and it is the step people skip.
| 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.
Take ninety seconds now: find your dwelling limit, find every percentage on your declarations page, multiply, and write the dollar figures in the margin. It is the single most useful thing most homeowners can do with their policy documents.
What to do if the higher figure is not affordable
The honest answer is that a deductible you cannot fund should not be chosen, however good the arithmetic looks. But there are other levers.
Alternatives worth pricing first
- Ask what discounts you qualify for and are not receiving — frequently the larger saving
- Ask what paying annually rather than monthly would save
- Ask whether mitigation measures attract a credit: an alarm, a water shutoff device, an updated roof
- Shop the market on matched coverage, which can move the premium more than a deductible change
- Consider a modest increase rather than a large one, since the first step usually has the best ratio
Raising the deductible is one lever among several, and it is the only one that costs you something later. It is worth pulling the others first.
Common misunderstandings
“The deductible comes off my repair bill” It comes off the covered amount after depreciation, which is frequently much less than the repair bill. That gap is where most of the surprise in a settlement comes from.
“My deductible is $1,000” Possibly for some perils. Wind, hail, hurricane and earthquake frequently carry separate and much larger deductibles on the same policy.
“It resets each year like health insurance” Property and auto deductibles generally apply per occurrence, not per year. Two separate covered losses mean two deductibles.
“A higher deductible always saves money” Over enough claim-free years, yes. Before the break-even point, no — and the break-even period varies enormously between insurers.
The second entry is the one that catches most homeowners. Run the calculator on each deductible your policy actually carries, not just the flat one on the front page.
One call, once a year
Ask your insurer for the premium at each available deductible level at renewal, and run the results through the calculator above. Rating structures change, so a step that was poor value two years ago can be reasonable now.
It is the same call that surfaces unclaimed discounts, so the two questions belong together and cost one conversation rather than two.
Ask for the figures in writing, and keep them with the previous year's so you can see whether the structure moved.
Two sets of figures side by side answer most questions about what changed and why.
