Raising a deductible lowers the premium. Whether that is a good trade depends on two things: how long it takes for the savings to cover the extra risk, and whether you could absorb the higher amount if a loss happened next week.
The break-even calculation
Simple arithmetic, and it is the whole question.
- Get the premium at both deductibles for the same coverage. Ask your insurer for a quote at each rather than estimating.
- Subtract to find the annual saving.
- Subtract the lower deductible from the higher to find the additional exposure.
- Divide the additional exposure by the annual saving. That is your break-even in years.
| Element | Example |
|---|---|
| Premium at $500 deductible | $1,850 |
| Premium at $1,500 deductible | $1,610 |
| Annual saving | $240 |
| Additional exposure | $1,000 |
| Break-even | 4.2 years without a claim |
The interpretation: if you go more than about four years between claims, the higher deductible has paid for itself. If you claim more often than that, it has not.
The break-even is only half the answer. The other half is whether you could pay the higher deductible tomorrow without borrowing. A deductible you cannot fund is not a saving — it is a claim you may not be able to make.
What the arithmetic leaves out
Claim frequency is not evenly spaced. Break-even assumes an average. Two hailstorms in one season means two deductibles in one year.
A higher deductible discourages small claims, which has a second-order effect. Claims affect your record and your future pricing, so absorbing a small loss yourself can be worth more than the deductible difference alone suggests. That is a real benefit the calculation does not capture.
Percentage deductibles do not behave like flat ones. If your wind or hurricane deductible is a percentage of the dwelling limit, it rises automatically as the limit rises. Run those numbers separately.
Where the trade tends to be better or worse
Better where you have savings that could absorb the higher amount, where the premium difference is large relative to the exposure, and where you rarely claim.
Worse where the higher deductible would require borrowing, where your area has frequent weather events, and where the premium difference is small — which happens more often than people expect at the upper end of the range.
That last point is worth testing. The saving from $500 to $1,000 is frequently larger than the saving from $2,500 to $5,000, because the insurer's exposure to small claims is where most of the cost sits.
Before you change it
- Check your mortgage. Lenders often cap the deductible on a mortgaged property.
- Check whether it applies per occurrence or per year, since property deductibles usually apply per event.
- Check every deductible, not just the main one. A separate wind or hail deductible may be the one that actually applies where you live.
What we are not saying
We are not telling you what deductible to carry. It depends on your savings, your risk exposure, and the actual numbers in your market.
What we are saying is that the break-even is a four-step calculation you can do with two quotes, that the saving from the first increase is usually larger than from later ones, and that a deductible you could not pay tomorrow is not a saving.
Where to verify this yourself
- Your insurer — written quotes at each deductible level, same coverage.
- Your declarations page — every deductible currently applying.
- Your mortgage documents — any cap the lender imposes.
