$500 vs $1,000 Car Insurance Deductible: How to Do the Break-Even Math

Last checked October 1, 2026

Key takeaways

• Moving from a $500 to a $1,000 deductible adds $500 to what you pay on each collision or comprehensive claim. The question is whether the yearly premium difference covers that.
• Break-even = $500 divided by your yearly premium difference. That is how many years you need to go between claims for the higher deductible to come out ahead.
• In 2024, about 4 in 100 collision policyholders and 4 in 100 comprehensive policyholders had a claim, according to ISO data published by Triple-I.

This guide is part of our car insurance coverage explained section. It does not tell you which deductible is cheaper for you, because only your own two quotes can answer that. It gives you the math to read those quotes.

How does a car insurance deductible work?

A deductible is the part of a claim you pay yourself. The Texas Department of Insurance gives the example: on a $1,500 collision claim with a $500 deductible, "the insurance company will deduct $500 from your claim amount and pay you $1,000."

Three details matter for this decision:

• It applies per claim, not per year. The Texas Department of Insurance notes that for auto policies "the deductible will be applied to each claim." Two claims in a year means two deductibles.
• It applies to collision and comprehensive (and in Texas, to uninsured motorist claims). The NAIC notes you pay it "even if you are not at fault for the damage" when you claim on your own policy, though Triple-I explains your insurer may recover it from the other driver's insurer and reimburse you.
• There is no deductible on a claim against another driver's insurance, per the Texas Department of Insurance.

How much does a higher deductible lower your premium?

It varies by insurer and car, so get both quotes. For general guidance:

• The Texas Department of Insurance says switching from a $500 to a $1,000 deductible "can save as much as 20 percent" on premium payments.
• Triple-I says moving from $200 to $500 "could reduce your collision and comprehensive coverage cost by 15 to 30 percent," and that going to $1,000 "can save you 40 percent or more."

Those percentages are upper ranges from the regulators and Triple-I, not a figure you can count on. The dollar difference on your own two quotes is the only number that goes into the math below.

How do you calculate the break-even point?

Ask your insurer for the same policy priced two ways: $500 deductible and $1,000 deductible on collision and comprehensive. Subtract. Call that your yearly premium difference.

Break-even years = $500 divided by yearly premium difference

If you go longer than that between claims, the higher deductible comes out ahead. If you claim more often, the lower deductible does.

Worked example. Say the $1,000 quote is $120 a year cheaper than the $500 quote. That is an illustrative input, not a quote.

• Break-even years = $500 / $120 = 4.17 years
• So if you file fewer than one claim every 4.17 years, the $1,000 deductible costs you less over time.

How often do drivers actually file claims?

Triple-I publishes claim frequency data from ISO, a Verisk business. In 2024:

ISO's physical damage figures are based on coverage with a $500 deductible.

Add the two frequencies and you get 8.11 claims per 100 car-years, or roughly one claim every 12.3 years for an average car (100 divided by 8.11). That is a national average across all drivers, not your personal odds.

Now turn it into dollars. The extra $500 you would pay per claim, times the chance of a claim in a year, is the expected yearly cost of the higher deductible:

Expected extra cost per year = 0.0811 x $500 = $40.55

That is an upper bound. Claims between $500 and $1,000 cost you less than the full extra $500, and some small claims you would simply not file.

So is a $1,000 deductible worth it?

On national averages, a premium difference above about $41 a year favors the $1,000 deductible over the long run. But two things can override the average.

Can you pay $1,000 tomorrow? Triple-I's advice: "Before choosing a higher deductible, be sure you have enough money set aside to pay it if you have a claim." The Texas Department of Insurance says the same: think about "how much you can afford to pay if your property is damaged." If $1,000 would go on a credit card, the math changes.

Are you more likely to claim than average? A long commute, street parking in a high-theft area, hail country or a new teen driver all push your odds above the national figure. Then the break-even table matters more than the average.

Small claims have a hidden cost: the Texas Department of Insurance warns that "filing small claims may affect how much you have to pay for insurance later." With a $1,000 deductible, you are less likely to file a $1,200 claim at all. Our guide on whether to file a claim or pay yourself covers that call.

Can you have different deductibles for collision and comprehensive?

Yes, they are usually set separately. Triple-I notes collision "is generally sold with a separate deductible," and comprehensive usually has its own too. Some drivers keep a lower comprehensive deductible because weather and theft are out of their control, and raise collision. Price both combinations.

Does the deductible matter on an older car?

More than you might think. A higher deductible lowers the most the coverage can ever pay you: on a car worth $4,000, a $1,000 deductible caps a total-loss payout at $3,000. At some point the better question is whether to keep the coverage at all. See when to drop full coverage and run your numbers in the liability-only vs full coverage break-even calculator.

FAQ

Is it better to have a $500 or $1,000 deductible? If your yearly premium difference is larger than $500 divided by the number of years you expect between claims, the $1,000 deductible costs less over time. You also need the cash to pay it.

Do I pay the deductible if the accident was not my fault? If you claim on your own collision coverage, yes at first. Triple-I says your insurer may recover from the at-fault driver's insurer and reimburse you. A claim made directly against the other driver's insurer has no deductible.

Is the deductible per year or per claim? Per claim on auto policies, according to the Texas Department of Insurance.

Does liability insurance have a deductible? No. Deductibles apply to coverage for your own car. Liability pays others up to your limits.

Does raising my deductible lower my whole premium? It lowers only the collision and comprehensive portions. Liability and other coverages are priced separately.
