Comprehensive vs. Collision: What Coverage Do You Need?

Shopping for car insurance means sorting through a variety of technical terms. Two of the most confusing terms you will encounter are comprehensive and collision coverage. Decoding this jargon helps you ensure your vehicle has the exact protection it needs without paying for unnecessary extras.

The Basics of Physical Damage Coverage

Most states require drivers to carry liability insurance. Liability coverage pays the other driver for their medical bills and car repairs if you cause an accident. However, liability insurance pays absolutely nothing toward fixing your own vehicle.

To protect the car you drive, you need physical damage coverage. This category of insurance splits into two distinct parts: comprehensive and collision. While people often buy them together, they cover entirely different sets of risks.

What is Collision Insurance?

Collision insurance is exactly what it sounds like. It pays to repair or replace your vehicle if you collide with another object or vehicle. This coverage applies regardless of who is at fault for the accident.

If someone else hits you, their liability insurance should technically pay for your repairs. But if you cause the accident, or if the other driver is uninsured, your collision coverage steps in to save the day.

Examples of collision claims include:

• Rear-ending another car at a stoplight.
• Sliding on black ice and hitting a street sign or telephone pole.
• Backing into your neighbor’s fence.
• Flipping your car on a sharp turn.
• Hitting a large pothole that damages your suspension.

According to data from the National Association of Insurance Commissioners (NAIC), the average cost of collision coverage in the United States is roughly $387 per year. Your exact price will vary heavily based on your driving record, your age, and the type of car you drive. A brand-new Tesla will cost much more to insure for collision than a ten-year-old Honda Civic because the repair costs are vastly different.

What is Comprehensive Insurance?

Comprehensive insurance covers damage to your car caused by events outside of your control. Because it handles non-driving accidents, insurance agents sometimes refer to this as “other than collision” coverage.

Examples of comprehensive claims include:

• A heavy tree branch falls on your hood during a windstorm.
• Your car is stolen from a grocery store parking lot.
• Vandals scratch your paint or slash your tires.
• A hailstorm shatters your windshield and dents your roof.
• You strike a deer or a bear crossing the highway (hitting an animal is almost always considered a comprehensive claim, not a collision claim).
• Floodwaters damage your engine.

Comprehensive coverage is generally cheaper than collision because catastrophic claims like floods or fires are less frequent than daily traffic accidents. The NAIC reports the average cost of comprehensive coverage is about $174 per year.

The Role of Deductibles

Both comprehensive and collision policies require you to select a deductible. A deductible is the specific amount of money you agree to pay out of pocket before your insurance company starts paying the repair bill.

Common deductibles are $250, $500, or $1,000. If you choose a $500 deductible and a hailstorm causes $2,000 in damage, you must pay the body shop the first $500. Your insurance company will then write a check for the remaining $1,500.

Choosing a higher deductible lowers your monthly insurance premium. Choosing a lower deductible increases your monthly premium. You should pick a deductible amount that you can comfortably afford to pull from your checking account at a moment’s notice.

Do You Actually Need Both?

If you currently finance or lease your car, you probably do not have a choice in this matter. Auto lenders like Chase Auto, Ford Credit, or your local credit union technically own the car until you pay off the loan. They require you to carry both comprehensive and collision coverage to protect their financial investment.

If you own your car outright, these coverages are strictly optional. This means you must do some math to decide if keeping them is worth the annual cost.

The 10 Percent Rule

Financial experts often recommend the 10 percent rule to help drivers decide when to drop physical damage coverage. First, look up the current value of your vehicle using Kelley Blue Book or Edmunds. Next, add up your total annual premium for comprehensive and collision coverage. If your yearly insurance cost is more than 10 percent of your car’s total value, it is likely time to drop the coverage.

For example, imagine you drive a 2008 Ford Focus with an actual cash value of $2,500. Your insurance company charges you $400 a year for comprehensive and collision, and you have a $500 deductible.

If you total the car in a wreck, the absolute maximum the insurance company will give you is $2,000 (the $2,500 value minus your $500 deductible). Paying $400 a year to protect a maximum payout of $2,000 does not make strong financial sense over the long term. You would be better off canceling the coverage and putting that $400 into a high-yield savings account to fund your next vehicle.

Frequently Asked Questions

What does “full coverage” car insurance mean?

There is no specific insurance product legally named full coverage. It is simply an industry nickname used by agents and buyers. When someone says they have full coverage, it generally means their policy includes state-mandated liability insurance alongside both comprehensive and collision coverage.

Can I buy comprehensive without buying collision?

Many major insurance companies like Geico, Progressive, and State Farm allow you to buy comprehensive coverage without buying collision coverage. This is a popular choice for people storing a classic car in a garage during the winter. They drop the collision coverage because the car is not being driven, but they keep the comprehensive coverage to protect against a garage fire or theft.

Does comprehensive insurance cover mechanical breakdowns?

No. Comprehensive insurance only covers external, sudden events like weather damage or theft. Normal wear and tear, blown engines, or bad transmissions are not covered by any auto insurance policy. You would need a separate mechanical breakdown policy or a dealer extended warranty to cover those specific issues.
