How Car Insurance Deductibles Work (and How to Choose One)

Your deductible is what you pay before insurance pays on a collision or comprehensive claim. Here is how it works, how it affects your premium and how to pick the right amount.

Your deductible is one of the few levers on your car insurance bill that you control completely. Set it too low and you overpay every month. Set it too high and a single claim can wreck your budget. Here is how to find the middle.

What a deductible is

A deductible is the amount you pay out of pocket on a claim before your insurance pays the rest. If you have a $500 collision deductible and a covered crash causes $3,200 of damage to your car, you pay $500 and the insurer pays $2,700.

Deductibles apply mainly to the coverages that protect your own car:

  • Collision (crashes, potholes, rollovers)
  • Comprehensive (theft, hail, flood, fire, vandalism, animal strikes)

Liability coverage, which pays for damage you cause to others, has no deductible for you to pay. In some states, other coverages such as PIP or uninsured motorist property damage can also carry a deductible.

How your deductible affects your premium

The NAIC lists $250, $500 and $1,000 as typical deductibles and notes that, generally, the higher the deductible, the lower the premium. The logic is simple: with a higher deductible, you absorb more of each small claim, so the insurer expects to pay less.

DeductibleYour premiumWhat you pay on a claimBest for
$250HighestLowestDrivers with little emergency savings
$500MiddleMiddleA common balance for many drivers
$1,000 or moreLowestHighestDrivers with a solid emergency fund

The actual premium difference varies by insurer, car and driver. Always ask for quotes at each level.

The break-even test

To see whether a higher deductible pays off, compare the extra risk you take on with the money you save each year.

  1. Get two quotes that are identical except for the deductible, for example $500 and $1,000.
  2. Find the extra risk: $1,000 minus $500 = $500 more out of pocket per claim.
  3. Find the yearly savings from the higher deductible, for example $150.
  4. Divide: $500 / $150 = about 3.3 years. If you usually go more than three years between claims, the higher deductible comes out ahead.

Example numbers for illustration only. Use your own quotes.

How to choose your deductible

  • Start with your emergency fund. Never choose a deductible larger than the amount you could pay tomorrow without borrowing.
  • Think about how you use the car. If you depend on it for work, you need to be able to pay the deductible quickly to get it repaired.
  • Consider separate amounts for collision and comprehensive. A lower comprehensive deductible can make sense where hail, theft or broken glass is common.
  • Check your lender's rules. Some loans and leases cap the deductible you are allowed to carry.
  • Revisit it every year. As your savings grow or your car ages, a higher deductible, or dropping collision entirely, may make sense. See full coverage vs. liability.

Small claims and your premium

A higher deductible also nudges you away from filing small claims, which is often a good thing: claims can raise your premium at renewal. If the damage is only slightly above your deductible, it can be cheaper over time to pay for the repair yourself. Our guide to filing a claim vs. paying out of pocket explains how to decide.

Frequently asked questions

Do I pay a deductible if the accident wasn't my fault?

If the other driver's insurer pays your claim, you usually don't pay a deductible. If you use your own collision coverage first, you may pay it, and your insurer may try to recover it from the at-fault driver's insurer later.

Is there a deductible for liability coverage?

No. Liability coverage pays the other party's losses, and there is no deductible for you to pay on those claims.

Can collision and comprehensive have different deductibles?

Yes. Many insurers let you choose them separately. Some drivers pick a lower comprehensive deductible because comprehensive claims, such as broken glass or hail, can happen even to careful drivers.

Is a $1,000 deductible a good idea?

It is a good idea if you have at least $1,000 readily available and the premium savings are meaningful. If paying $1,000 after a crash would cause financial trouble, a lower deductible is safer.
