If you have ever purchased car insurance, you have had to make a decision about your deductible.
For many drivers, it is just a number they pick to lower their monthly premium, without fully understanding how it impacts them if they actually need to use their insurance.
Understanding how car insurance deductibles work is one of the most important parts of managing your financial risk. It determines how much you pay out of pocket after an accident, and it plays a major role in how much your insurance costs every month.
What Is a Car Insurance Deductible?
A deductible is the amount of money you agree to pay out of pocket before your insurance company steps in to cover the rest of a claim.
Unlike health insurance, where you might have an annual deductible that you meet over time, car insurance deductibles generally apply per incident.
For example, if you accidentally back your car into a pole and cause $3,000 in damage, and your deductible is $1,000, you pay the first $1,000. Your insurance company then writes a check for the remaining $2,000 to the repair shop.
If you have another accident a month later, you will generally have to pay the deductible again for the new claim.
Different Deductibles for Different Coverages
You do not just have one single deductible for your entire policy. You usually select a different deductible for different types of coverage, most commonly for Comprehensive and Collision insurance.
- Collision Deductibles: Apply when your vehicle collides with another object or vehicle and you are considered at fault.
- Comprehensive Deductibles: Apply for damage outside of your control, such as theft, vandalism, hail damage, or a windshield shattered by falling tree branches.
Depending on your situation, many drivers choose to carry a higher deductible for Collision (e.g., $1,000) because they are willing to take on more risk for an at-fault accident, but they might select a lower deductible for Comprehensive (e.g., $500) since events like theft or animal strikes are completely out of their control.
How Deductibles Affect Your Premium
There is a direct relationship between your deductible and your insurance premium (the amount you pay every month or year).
If you choose a higher deductible, you are taking on more financial responsibility in the event of an accident. Because the insurance company takes on less risk, they generally charge you a lower premium.
If you choose a lower deductible, your insurance company has to pay out more money if you file a claim. To offset that risk, they charge you a higher premium.

When Does a Deductible Not Apply?
In many situations, you will not have to pay a deductible at all.
The most common scenario is a not-at-fault collision. In many provinces with Direct Compensation Property Damage (DCPD) systems, if another driver rear-ends you and is 100% at fault, your insurance company typically covers your repairs without requiring you to pay your deductible.
However, if the accident is a hit-and-run and the other driver cannot be identified, you will typically be forced to use your Collision coverage, which means your deductible will unfortunately still apply.
The Part Most People Miss
The biggest misunderstanding drivers have about deductibles is how they apply during a total loss.
Many people assume that if their car is completely destroyed or stolen, the insurance company simply writes them a check for the full value. In reality, the deductible is still subtracted from the final settlement.
If your vehicle's Actual Cash Value (ACV) is determined to be $15,000, and you have a $1,000 deductible, your final payout will be $14,000. If you are also carrying a loan and the payout is less than your balance, this is exactly where GAP insurance becomes critical.
The second thing people often miss is evaluating their deductible against the actual value of an older vehicle. As cars naturally depreciate, carrying a high deductible may no longer make financial sense.
If you drive an older car worth only $3,500 and carry a $1,000 deductible, any claim you file will significantly reduce the value of the settlement. Even moderate hail damage could trigger a total loss, and after the deductible is removed, the payout might be too small to comfortably replace the vehicle.
This is why establishing an educational benchmark of your vehicle's market value is so important—it helps you understand exactly how much financial risk you are carrying, and whether your deductibles still align with the realistic value of your car.
Frequently Asked Questions
Some insurers offer policies or specific coverages (like glass/windshield coverage) with a $0 deductible, meaning you pay nothing out of pocket for a claim. However, coverage can vary, and these policies often come with significantly higher monthly premiums.
You can change your deductible at any time by contacting your insurer, but the change will only apply to future accidents. You cannot lower your deductible to save money on a claim that has already happened.
