Car insurance deductibles are one of the few parts of an auto policy you can adjust yourself, and the choice you make shows up in two places: the premium you pay every month and the amount you pay out of pocket when your car is damaged. Pick a deductible that is too low and you may be paying extra for protection you rarely use. Pick one that is too high and a single fender bender could strain your budget.
This guide explains what a deductible is, which coverages use one, why changing it moves your premium, and a simple way to test whether a higher deductible actually saves you money. The examples are hypothetical, but the method works with the real quotes you get from insurers.
What a Car Insurance Deductible Is
A deductible is the share of a covered claim that you are responsible for paying before the insurer pays the rest. If your car needs $3,000 of covered repairs and your deductible is $500, you cover the first $500 and the insurer covers the remaining $2,500, subject to the terms and limits of your policy.
Consumer guides from the National Association of Insurance Commissioners (NAIC) list $250, $500 and $1,000 as common deductible amounts. Many insurers offer other options, so ask what levels are available when you request a quote.
Which coverages usually carry a deductible
- Collision coverage: Pays for physical damage to your vehicle when it hits another car or an object, such as a tree. If the car is totaled, it pays up to the vehicle’s actual cash value. Collision usually has a deductible.
- Comprehensive coverage: Sometimes called “other than collision,” it pays for damage from events like theft, fire, vandalism, hail, flood, falling objects or animal strikes. It also usually has a deductible.
Together, collision and comprehensive are often called physical damage coverages. Liability coverage, which pays for injuries and property damage you cause to others, works differently, and the state consumer guides used for this article do not describe a deductible for it.
Why a Higher Deductible Lowers Your Premium
When you agree to carry a larger share of each loss, the insurer expects to pay less on your claims, so the price of the coverage drops. The NAIC notes that you may reduce your auto insurance costs by raising the deductibles on collision and comprehensive coverage. A state buyer’s guide reprinting NAIC material makes the same point from the other direction: rates are higher for policies with lower deductibles.
How much you save depends on your insurer, your vehicle, where you live and your driving record, which is why the only reliable number is the one in your own quote. Ask each insurer to price the same policy at two or three deductible levels so you can see the actual difference.
Low vs. High Deductible at a Glance
| Factor | Lower deductible (for example, $250) | Higher deductible (for example, $1,000) |
|---|---|---|
| Premium | Higher | Lower |
| Out-of-pocket cost per claim | Smaller | Larger |
| Best suited to | Drivers with limited savings who want predictable costs after an accident | Drivers with an emergency fund who could absorb the deductible easily |
| Small claims | More small repairs are worth filing | Many minor repairs fall below the deductible and are paid by you |
| Main risk | Paying for protection you may not use | A large bill at a bad time if you have a claim |
How to Calculate Your Break-Even Point
A quick break-even test tells you how long it would take for premium savings to cover the extra out-of-pocket cost of a higher deductible.
- Get two quotes for identical coverage that differ only in the deductible.
- Subtract the higher-deductible premium from the lower-deductible premium to find your annual savings.
- Subtract the lower deductible from the higher deductible to find the extra amount you would pay per claim.
- Divide the extra per-claim cost by the annual savings. The result is the number of claim-free years needed to come out ahead.
A hypothetical example
The figures below are hypothetical and are not real quotes.
- Policy with a $500 deductible on collision and comprehensive: $1,500 per year.
- Same policy with a $1,000 deductible: $1,350 per year.
- Annual savings: $150. Extra cost per claim: $500.
- Break-even: $500 divided by $150 is about 3.3 years.
If this driver goes roughly three and a half years without a physical damage claim, the higher deductible pays for itself. If they expect to file a claim sooner, or would struggle to come up with $1,000 on short notice, the lower deductible may be the safer choice. Run the same math with your own quotes; the savings can be larger or smaller than this example.
When Raising Your Deductible Can Make Sense
- You have cash set aside. NAIC guidance stresses checking that you could comfortably pay the deductible after an accident before you raise it.
- You rarely file small claims. If you would pay for minor dings yourself anyway, a low deductible may be buying little real value.
- The premium difference is meaningful. If the break-even period is short, the trade-off is more attractive.
- Your budget needs a lower monthly bill. A higher deductible is one lever among several; our guide to comparing car insurance plans covers others.
When a lower deductible may be wiser
- You do not have an emergency fund that could cover a higher deductible.
- Your premium savings from raising it are small, making the break-even period long.
- You park in an area where theft, vandalism or weather damage is common and you expect to use comprehensive coverage.
Deductibles on Older or Financed Cars
For an older vehicle, the question may go beyond the deductible. The NAIC suggests considering lowering or eliminating physical damage coverage on older vehicles, because the premium you pay can approach what the insurer would pay out after subtracting your deductible. Before dropping coverage, weigh the car’s value and the cost to repair or replace it against what you would save.
If you still owe money on the car, check your loan or lease agreement first. Lenders may require collision and comprehensive coverage until the loan is paid off, so you might not be able to drop it, and you should confirm whether the lender limits how high your deductible can be. Once the loan is paid, contact your insurer to remove the lienholder from your policy.
A hypothetical older-car check
Suppose a paid-off car is worth about $3,500 and you carry a $1,000 collision deductible. The most collision would pay on a total loss is roughly $2,500 before any other adjustments. If collision coverage costs $500 a year, you are paying a sizable share of the maximum benefit every year. These numbers are hypothetical; check your car’s value and your actual premium before deciding.
How Deductibles Work When You File a Claim
According to state consumer guidance, you pay your deductible whenever you file a claim for damage to your own vehicle under collision or comprehensive, even if the accident was not your fault. In practice, the insurer usually reduces its payment by the deductible amount, so you pay that portion to the repair shop.
When another driver caused the accident, your insurer may later pursue that driver’s insurer. Our explainer on subrogation in insurance walks through how that recovery process works. For the step-by-step claim process itself, see our guide on how to file an insurance claim.
Tips before you change your deductible
- Compare quotes with identical coverage and deductibles across insurers so the prices are truly comparable.
- Ask whether collision and comprehensive can have different deductibles.
- Set aside the deductible amount in savings once you raise it.
- Review your choice when your car’s value, loan status or finances change.
Frequently Asked Questions
Does liability insurance have a deductible?
The consumer guides reviewed for this article describe deductibles for collision and comprehensive, not for liability coverage. Liability pays others for damage or injuries you cause. Check your own policy’s declarations page for details.
Do I pay the deductible if the accident was not my fault?
If you file the claim under your own collision coverage, state consumer guidance says you generally pay the deductible even when you are not at fault. Your insurer may then seek recovery from the at-fault party.
What deductible amounts are common?
The NAIC lists $250, $500 and $1,000 as common amounts. Available options vary by insurer.
Can I change my deductible mid-policy?
Many insurers allow changes, but rules differ. Contact your insurer or agent to ask how a change would affect your premium and when it takes effect.
Bottom Line
A higher deductible on collision and comprehensive generally lowers your premium, while a lower deductible costs more but reduces what you pay after an accident. Choose the highest amount you could comfortably pay on short notice, run a break-even check with real quotes, and revisit the decision as your car ages or your loan is paid off. Your state insurance department can answer questions about coverage rules where you live.
