Comprehensive insurance pays to repair or replace your car when something other than a collision damages it, such as theft, hail, fire, a falling tree, or hitting an animal. Collision insurance pays to repair or replace your car when it is damaged in a crash with another vehicle or object, including a crash where you are at fault. Together they are the physical damage coverages on a personal auto policy, the parts that protect your own car rather than paying for damage you cause to others. Most drivers buy them as a pair, usually because a lender requires it, but they are separate coverages with separate deductibles, and knowing how they divide a claim is what keeps a repair bill from surprising you.
This guide does not repeat the side-by-side comparison of the two coverages. That comparison lives here, and it covers what each coverage pays for in detail. Instead, this guide answers the question people actually ask at renewal time: what does it mean to carry both, how do they work together when one incident touches both, what does the pair cost, and when can you drop one or both without taking a foolish risk.
What do comprehensive and collision insurance cover, in one sentence each?
Comprehensive insurance covers damage to your car from events that are not collisions, including theft, vandalism, fire, weather, falling objects, and animal strikes, minus your comprehensive deductible. Collision insurance covers damage to your car from hitting, or being hit by, another vehicle or an object such as a fence, pole, or guardrail, minus your collision deductible, including crashes that are your fault. Neither coverage pays for injuries, damage to other people’s property, or routine maintenance.
The line between them is the cause of the damage, not the size of the bill. A deer strike is comprehensive, because the animal is not a vehicle or a fixed object you collided with in the usual sense, and insurers classify animal strikes as comprehensive claims. Swerving to miss the deer and hitting a fence is collision, because the fence is an object you struck. Hail damage to the roof is comprehensive. A parking lot scrape is collision. Flood and fire damage are comprehensive. A hit-and-run where the other driver cannot be identified is usually handled as a collision claim, and in some states it can fall under uninsured motorist property damage instead, which is a separate coverage with its own deductible rules.
Both coverages pay up to the actual cash value of the car, which is its market value just before the loss, minus depreciation. The Insurance Information Institute reports that the average collision claim in 2024 was $5,489 and the average comprehensive claim was $2,306, based on ISO data. Those averages explain why collision coverage costs more than comprehensive coverage: collision claims are both more frequent, 4.16 percent of collision policyholders had a claim in 2024 against 3.95 percent for comprehensive, and more expensive when they happen. If your car is worth $4,000, a $5,489 average collision claim is a reminder that most collision claims on older cars end with the car totaled, not repaired.
How do comprehensive and collision work together on one incident?
When a single incident causes both kinds of damage, the insurer splits the loss by cause and applies each coverage, and each deductible, to its own part of the damage. You can owe two deductibles on one event, one for the comprehensive portion and one for the collision portion, although some insurers and some state rules handle combined losses differently. Ask your insurer how it handles a combined loss before you assume one deductible covers the whole event.
Take the deer example and follow it through. A deer runs into the road at night. You brake, clip the deer, swerve, and hit a fence. The front-end damage from the deer is a comprehensive loss, because an animal strike is a comprehensive peril. The side damage from the fence is a collision loss, because you struck a fixed object. The adjuster writes two estimates, one for each cause. If your comprehensive deductible is $500 and your collision deductible is $500, you could owe $1,000 across the two parts, and the insurer pays the rest up to the car’s actual cash value. If the total damage is less than the two deductibles combined, you may be better off not filing at all, which is a conversation to have with your agent before the claim is recorded.
Not every messy incident splits this way. A tree that falls on your parked car is one comprehensive loss, even if the car then rolls into a wall, because the falling tree is the single cause. A storm that floods the car and then the car is struck by debris in the same storm is usually one comprehensive loss as well. The split happens when two different causes, one comprehensive and one collision, each damage the car in the same event. The adjuster’s job is to assign each dent to a cause, and your job is to describe the sequence of events accurately and in order, because the order decides which coverage applies to which damage.
There is one more combined-loss trap: the rental car. Neither comprehensive nor collision coverage pays for a rental car while yours is repaired unless you also carry rental reimbursement coverage. A car in the shop for three weeks after a collision claim can cost more in rental fees than the deductible, and people discover the gap only when the shop calls to say the car is ready in two weeks. Check your declarations page for rental reimbursement before you need it. Gap insurance is a separate question too: if you owe more on the loan than the car’s actual cash value, comprehensive and collision pay only the value, and gap coverage pays the difference.
What does carrying both cost?
Full coverage insurance, which usually means liability plus comprehensive and collision, cost an average of $2,098 a year in AAA’s 2026 Your Driving Costs study, for a driver under 65 with more than six years of experience, no accidents, and a suburban or urban home. That figure, reported by the Insurance Information Institute, is an average for all vehicles, not a quote for your car. Your price depends on the car’s value, your driving record, where you live, and the deductibles you choose. The physical damage pair is the expensive part of the policy: the Institute reports that 80 percent of insured drivers buy comprehensive coverage and 77 percent buy collision coverage, and that collision and comprehensive premiums together grew 14.3 percent in 2024.
Collision coverage costs more than comprehensive coverage for the same car and deductible, because collision claims are larger and more frequent. Raising your deductibles is the most direct way to cut the pair’s cost. Moving a collision deductible from $250 to $1,000 typically saves a meaningful percentage of the collision premium, and the same move on comprehensive saves less in dollars because comprehensive is cheaper to begin with. Choosing deductibles for the two coverages is covered in detail on this site, including when a high deductible makes sense and when it does not.

State and vehicle choice move the price more than any discount. A car that costs more to repair, a ZIP code with more hail or theft, and a driver with a recent at-fault accident all raise the physical damage premium. Shopping the pair as a package, with the same deductibles, across three or four insurers is the only reliable way to know your price. Online averages are a starting point, and quotes are the answer.
When are you required to carry comprehensive and collision?
No state requires comprehensive or collision coverage by law. What requires them is usually a loan or lease agreement. If you finance or lease a car, the lender or leasing company almost always requires both coverages, with a maximum deductible, until the loan is paid off or the lease ends. The lender is protecting its collateral, and it can force-place insurance at a high price if you drop the coverages, which is worse than buying them yourself. Check the agreement for the maximum deductible allowed, because a $1,000 deductible that saves premium may violate a lender’s $500 maximum.
Once you own the car outright, the decision is yours. That is when the math matters. The question is not whether the coverages are good in general. It is whether the premium you pay each year is worth the most the insurer would ever pay you, which is the car’s actual cash value minus your deductible. A car worth $3,000 with a $500 deductible has a maximum collision payout of $2,500. If collision coverage costs $600 a year, you are paying $600 to protect at most $2,500, and you would break even only if you totaled the car more often than once every four years. Most drivers in that position drop collision first, keep comprehensive longer, or raise both deductibles. When dropping full coverage saves money works through that math with more examples.
When does keeping only one of the two make sense?
Keeping comprehensive and dropping collision makes sense when the car’s value is low, the car is rarely driven in traffic, and the risks you worry about are theft, weather, and vandalism rather than crashes. A car parked on the street in a hail-prone area, or a second car that mostly sits in a garage, can justify comprehensive alone, because comprehensive is the cheaper coverage and it covers the risks that find a parked car. Keeping collision and dropping comprehensive makes sense less often, because collision is the expensive half, but it can fit a driver in a low-theft, mild-weather area who drives daily in heavy traffic and worries most about a crash.
Work through a concrete case with stated numbers. A 2012 sedan is worth $4,500. Collision coverage costs $520 a year with a $500 deductible, so the maximum payout is $4,000 and the premium is 13 percent of the car’s value every year. Comprehensive coverage costs $180 a year with a $250 deductible, so the maximum payout is $4,250. Dropping collision saves $520 a year and leaves the driver self-insuring a $4,000 risk. Dropping comprehensive saves $180 and leaves the driver exposed to hail, theft, and a deer strike. Many drivers in this position drop collision, keep comprehensive, and put the $520 toward the next car’s savings. The numbers are illustrative, using a stated car value and stated premiums, and your own quotes decide the real answer.
Age of the car is not the only factor. A car with a loan, a car you cannot afford to replace, and a car you depend on for work all argue for keeping both coverages longer than the value math alone suggests. A car you could replace from savings, a second car, and a car driven a few thousand miles a year all argue for dropping sooner. The decision is about your ability to absorb the loss, not just the car’s age. If totaling the car would leave you without transport and without the cash to replace it, keep the coverages and raise the deductibles instead of dropping them.
How should you set the deductibles for the pair?
Set each deductible at an amount you can pay without borrowing, and do not set them equal out of habit. Many drivers carry a lower comprehensive deductible, such as $250 or even $100, because comprehensive claims are often glass and weather damage in the low hundreds, and a $500 comprehensive deductible would mean paying most small claims yourself. The same drivers carry a higher collision deductible, such as $1,000, because collision claims are larger and the premium saving is bigger. That split reflects how the two coverages are actually used, and it is the structure the deductible guide on this site recommends for most drivers.
Before you raise a deductible, check two things. First, confirm the lender’s maximum deductible if the car is financed. Second, confirm you have the deductible amount available in savings for each coverage separately, because a combined loss can require both. A $1,000 collision deductible and a $500 comprehensive deductible mean $1,500 of cash on hand for the worst single event. If that amount would strain you, lower the deductibles and accept the higher premium. Insurance that you cannot afford to use is not insurance.
Key takeaways
Comprehensive covers non-collision damage to your car, collision covers crash damage, and together they protect your own vehicle up to its actual cash value. A single event can trigger both, and you can owe both deductibles. No state requires either coverage, but lenders almost always do. Once you own the car, compare the annual premium with the maximum payout, the car’s value minus the deductible, and drop or raise deductibles when the premium no longer buys enough protection. Keep the deductible amounts in savings, and check rental reimbursement and gap coverage separately, because neither comes with the pair.
Frequently asked questions
Do I need both comprehensive and collision insurance?
You need both if you have a loan or lease that requires them. If you own the car outright, you need them only if you cannot afford to repair or replace the car yourself. Most drivers carry both, but dropping one or both is a legitimate choice when the car’s value is low and the premium is high relative to that value.
What happens if one accident causes comprehensive and collision damage?
The insurer splits the loss by cause, applies comprehensive coverage to the non-collision damage and collision coverage to the crash damage, and can apply both deductibles. Describe the sequence of events accurately, because the order decides which coverage applies to each part of the damage.
Does comprehensive insurance cover hitting a deer?
Yes. Animal strikes are comprehensive claims. If you swerve to miss the animal and hit a fence or pole, the fence damage is usually a collision claim, so one event can produce both kinds of claim. Tell the adjuster exactly what happened, in order.
How much does comprehensive and collision insurance cost?
AAA’s 2026 study put average full-coverage insurance, which includes liability plus comprehensive and collision, at $2,098 a year for a clean-record driver. Collision costs more than comprehensive for the same car. Your price depends on the car’s value, your record, your location, and your deductibles, so get quotes with identical deductibles to compare.
Can I drop collision but keep comprehensive?
Yes, if you own the car outright and no lender requires both. Many drivers drop collision on older, low-value cars and keep comprehensive for theft, hail, and vandalism. Check your loan agreement first, and make sure you can afford to replace the car if it is totaled in a crash you cause.
