What Happens if You Raise Your Car Insurance Deductible
Raising your deductible lowers your premium because you're agreeing to pay more yourself before coverage kicks in on a claim.
You're trading a lower bill now for more risk later
A deductible is the amount you pay before your insurer pays anything on a claim involving damage to your own car. When you raise it, you're telling the insurer you'll absorb more of the small and medium losses yourself, so they lower what they charge you for taking on less of that risk. That's the entire mechanism. Nothing else about your policy changes.
The savings show up because insurers price for the claims they expect to pay. A higher deductible means fewer small claims get filed at all, since many people won't bother submitting a claim for an amount close to or below their deductible. That shifts cost away from the insurer and onto you, and the premium reflects that shift.
This only affects collision and comprehensive coverage, the parts of your policy that pay for damage to your own vehicle. It has no effect on liability coverage, which pays for damage you cause to others, because liability doesn't work on a deductible at all. If most of your premium is liability, raising your deductible won't move the bill as much as you'd expect.
Where this plays out differently is in how often you actually file claims and how much cash you'd have on hand to cover a higher deductible if something happened tomorrow. If your car is older and worth little, a high deductible paired with full coverage can mean you're paying for coverage that would barely pay out anyway. Check with your insurer how the premium changes at each deductible level, since the savings aren't always proportional.
What actually changes when you raise it
- Your premium drops This is the direct effect and the reason people do it. Ask your insurer for a quote at a few deductible levels so you can see the real difference, not just an estimate.
- Your risk out-of-pocket rises If you file a claim, you pay more before coverage starts. Make sure you have that amount sitting in savings before you raise the deductible, not just in theory.
- Liability is untouched Deductibles only apply to collision and comprehensive, not to coverage for damage you cause others. Don't expect a big change if liability is most of your bill.
- Small claims cost more to file A higher deductible means minor damage may cost less to pay yourself than to file a claim. Decide in advance whether you'd actually use the coverage at that level.
- It resets with each claim Each separate incident requires you to meet the deductible again. Factor that in if you expect more than one claim is possible in a given year.
A parent deciding on the car sitting in the driveway
A parent had a car left behind after their child moved out, still insured with a low deductible because a new driver had once used it. The car was older, worth modestly, and now driven only occasionally by the parent for errands. They called their insurer to ask what raising the deductible would do to the premium, and the drop was noticeable enough to matter, since the car was rarely driven and the odds of a claim felt low.
Before deciding, they checked their savings to make sure they could cover the higher amount if the car were ever damaged, and confirmed the car was worth enough that full coverage still made sense at all. They raised the deductible on that car but left the deductible on the car they drove daily alone, since that one saw more mileage and more risk. The result was a lower bill on the car doing the least work for them, without changing anything about the coverage they relied on every day.
Compare quotes at your new deductible level to see exactly what you'll save before you make the change.
What deductible amount should I actually choose?
Choose an amount you could pay in cash today without strain, since that's the real test. A deductible that saves money on paper but would force you to borrow after an accident defeats the purpose. Check your savings first, then compare premiums at a few levels your insurer offers. If one level barely changes the premium, there's little reason to take on the added risk, so always compare the actual dollar savings rather than assuming a bigger jump means bigger savings.
Should both cars on my policy have the same deductible?
Not necessarily, since each car can carry a different deductible based on its value and how much it's driven. A rarely used car with modest value can often carry a higher deductible with little downside. A car driven daily by someone commuting or running errands constantly carries more exposure, so a lower deductible may make more sense there. Ask your insurer whether they allow different deductibles per vehicle on the same policy, since most do.
Does raising my deductible affect my ability to file a claim later?
No, it only affects how much you pay before coverage starts, not whether you can file. You can still file a claim at any time regardless of your deductible amount. What changes is whether it makes financial sense to, since a claim near or below your deductible may cost you more in future premium increases than it's worth filing. Always weigh the repair cost against the deductible and the likely effect on your rate before deciding to file.
The deductible you choose should match what you could pay today, not what lowers the bill the most.
