Insurance deductibles explained: What they are and how they work

Insurance deductibles affect what you pay for insurance and how your coverage works. This guide explains what an insurance deductible is, how it impacts home and auto premiums, and why it matters for business insurance. It also helps you choose the deductible that best fits your needs.

An insurance deductible is the amount that’s deducted from the payout your insurance company makes in the event of a covered claim. 

Deductibles exist to even out the risk between you and the insurer. They help discourage small claims and keep insurance premiums affordable.

Say you choose a $500 deductible when you take out your car insurance policy. If you had a covered claim and the repairs cost $3,000, you’d be responsible for the first $500 and your insurance company would pay the remaining $2,500. Let’s take a closer look at deductibles for different types of insurance.

Deductibles apply in different ways depending on the type of car insurance coverage. Liability coverage, for example, usually doesn’t have a deductible because it’s primarily designed to protect other people. 

But you generally will have a deductible when it comes to optional coverages. You can often choose different deductible amounts for different types of coverage. For example, you could choose a $500 collision insurance deductible and a $250 deductible for comprehensive (which includes things like theft, vandalism and glass damage). These deductibles apply on a per-claim basis, which means you have to pay the deductible each time you submit a claim.

Some insurers offer disappearing deductibles—also known as vanishing deductibles—to encourage safe driving. This type of  deductible shrinks down to nothing over time if you maintain a clean driving record. 

For greater peace of mind, you might want a $0 deductible. This means your insurance could cover the full cost from the start, though premiums for this type of coverage are usually higher.

Insurance deductibles are an important cost-control tool for insurance providers. 

If there were no deductibles in car insurance, for example, insurers would have to pay out for every minor scratch and fender bender, and that would drive premiums up for everyone. Requiring insureds to pay for a portion first helps discourage claims for minor damage and keep insurance costs manageable for everyone.

Home claims don’t tend to happen as often as auto claims, but when they do happen, they can be really expensive. That’s why deductibles matter: they help insurers manage risk and keep premiums reasonable for their customers.

Generally speaking, home insurance deductibles aren’t that complicated. Most insurance policies have a single, flat, per-claim deductible. However, different deductibles may apply if you add optional coverage for things like sewer backup or flood. For example, you might have a $1,000 deductible for your basic homeowner’s policy and a separate $500 deductible for sewer backup coverage.

For some risks, like earthquakes, things can be a little different. Instead of a flat amount, you sometimes see percentage-based deductibles. In earthquake-prone areas like British Columbia, for example, you can expect earthquake deductibles of between 5% and 20% of the total insured value of the property, with 10% to 15% being most common.

It’s a good idea to see if your policy has separate deductibles for specific perils, like wind and hail. They’re more common in areas that tend to get a lot of hail, so you may want to check your policy if you live in a hail-prone area. You may also want to check whether optional endorsements like sewer backup or flood are available and cost-effective.

Personal home and auto insurance deductibles are pretty straightforward. They’re usually a fixed amount. But when it comes to business insurance deductibles, the stakes are higher for every type of company, from retail to construction. Commercial insurance deductibles can range from $500 to $100,000. These higher deductibles reflect the scale of potential losses and the financial capacity of businesses to absorb some of the risk.

Business insurance deductibles vary based on the type of coverage and how your policy is structured. The type of coverage affects how and when you pay out of pocket. Understanding these differences helps you manage risk and control costs effectively.

Per-claim deductible

A per-claim, or per-event, deductible applies to each individual claim. So if you have a $1,000 deductible and you submit eight different claims, you’ll have to pay $8,000 (8 claims X $1,000 deductible). This type of deductible is common in liability and property coverage.

Annual aggregate deductible

This type of deductible adds up over the term of your policy. Once you’ve paid the aggregate amount, the insurer will cover any subsequent losses, which helps limit your total out-of-pocket costs. With an annual aggregate deductible of $10,000, if you made three claims of $5,000, $8,000, and $12,000 over the course of a year, you would have to pay the first claim in full and $5,000 of the second to reach your deductible. Your insurer would cover the remaining $3,000 of the second claim and all of the third claim, plus any other claims for the rest of the policy term.

Percentage-based deductible

Percentage-based deductibles are calculated as a percentage of the insured value (rather than a fixed dollar amount). They help balance costs between the business and the insurer, especially when it comes to high-value assets. They’re common in contractor’s equipment insurance and catastrophe coverage. 

If your equipment is insured for $2 million and you have a 5% deductible, your deductible would be $100,000. So if a covered loss occurred, you’d be responsible for paying $100,000 before your insurer would step in.

Deductibles are a risk-management tool for your business. They’re an incentive to incorporate loss prevention strategies, and retaining some of the risk can help you lower your premiums. To determine the right deductible for your business, it’s a good idea to work closely with an insurer.  

Though some deductibles are mandatory, choosing the right deductible amount is generally a personal decision. You’ll want to strike a balance between affordability and protection. There are a number of factors worth considering when making your decision.

Your deductible impacts both your premiums and the amount you’d have to pay out of pocket for a claim. Possible considerations include your budget, your risk tolerance and your claims history.

Your budget and financial capacity

Ask yourself: if something were to happen tomorrow, would it be hard for you to cover the deductible? If so, it might make sense to choose a lower deductible. If you’ve got a solid emergency fund, though, a higher deductible could help you save on premiums.

Your risk tolerance

If it would be hard for you to pay a large amount out of pocket, a lower deductible might be the safer choice. If you’re OK with a little more financial risk, however, a higher deductible might be worth it to you. 

Your claims history

If you’ve rarely had to file a claim, a higher deductible might make sense. But depending on your claims history and the likelihood of future claims, choosing a lower deductible could be the more practical option.  

Higher deductibles usually mean lower premiums, while smaller deductibles mean higher premiums. But a high deductible doesn’t necessarily equal big savings. Sometimes the premium reduction is minor compared to the extra out-of-pocket costs you’d have to shoulder if you had to file a claim. 

So before you choose your deductible, it’s a good idea to run the numbers and consider your risk tolerance. Ask yourself: if you had to make a claim, could you afford to pay the extra money out of pocket? Often, the savings aren’t worth the financial strain, so make sure to look at the whole picture before deciding.

A wide range of deductible amounts are available in Canada, depending on factors like the type of coverage, the risk level, your policy options and your province’s regulations. 

For personal insurance, auto insurance deductibles can vary dramatically: from $250 to $25,000. Homeowner’s insurance deductibles, which are more complex, also run the gamut from $300 to $20,000.

A good rule of thumb is to think about your deductible and your premium together, even though you always have to pay your premium (and hope to never have to pay a deductible)! 

If your claims history is pretty clean and you have a low risk profile (clean driving record, new roof), you might feel comfortable with a higher deductible. If, on the other hand, you’ve had to submit claims in the past or live in an area with a high risk of severe weather (e.g., hailstorms, wildfires, flooding), it may be more practical to choose a lower deductible.

Remember: increasing your deductible isn’t the only way to help lower your premium. Bundling your home and auto policies with one insurance provider can often unlock discounts. Maintaining a clean driving record can also help with car insurance. And when it comes to home insurance, adding security features like a monitored home security system may reduce your risk and lead to better pricing.

Here’s a quick rundown of the main things to keep in mind to help you pick a deductible that’s right for you: 

• Balance matters: Choosing the right deductible can help you manage premiums and protect your finances.
• Review regularly: Check your insurance needs annually and after major life changes.
• Plan ahead: Make sure your deductible fits your budget and risk tolerance.
• Get expert advice: Talk to an insurer if you’re unsure about the best option.
