Full Coverage or Liability Only: Keep It or Drop It

The decision is two line items, not the whole policy

Liability isn't on the table. Your state makes you carry it, it pays for the car you hit and the person you hurt, and it stays.

The decision is two line items: comprehensive and collision.

Together they run about $828 to $1,476 a year on top of the liability you'd carry anyway. That spread comes out of the 2026 national rate studies. They put average full coverage anywhere from $1,632 to $2,926, depending on whose data you read — MoneyGeek at the bottom, Experian at the top, with LendingTree at $2,124, NerdWallet at $2,315 and Insurance.com at $2,575 in between. Liability alone averages $621 to $1,576 at state-minimum limits, and $816 to $1,176 on a more typical policy — LendingTree at the low end, Insurify at the high end.

So the question is narrow. Is the car worth enough that comp and collision could ever pay back what they cost?

An old Insurance Information Institute rule answers it: when the car is worth less than ten times the price of the coverage, carrying it may no longer be cost-effective. Flipped around, that's the 10% line. ValuePenguin draws it earlier, at four to six times the annual cost — usually a car 8–12 years old and worth $5,000–$10,000.

Three numbers, twenty minutes, kitchen table

Before you call anyone, sit down for twenty minutes with three figures and nothing else.

• The car's actual cash value. Not the dealer's asking price — what an adjuster pays on a total loss, which sits closer to auction money. Check two guides, take the lower one.
• Your deductible, because it comes off every payout. A total loss on a $5,000 car with a $500 deductible pays the value minus the deductible, not the full five grand.
• The comprehensive and collision lines on your declarations page. Two numbers, added together. Not your whole premium — that's where people talk themselves into keeping coverage that costs a fraction of what they assumed.

When keeping it is the right call

Sometimes the math doesn't get a vote.

Financed or leased? The lender requires comprehensive and collision, and no calculation changes that. The decision waits until the last payment clears.

Past that, keep the coverage when a sudden $5,000–$10,000 hole would land on a credit card instead of a savings account. Keep it when the car is the only way you get to work. Keep it when there's a teenager on the policy and the odds of a claim went up the day they got their license.

Age is a proxy for value, not the thing itself. Insure.com found full coverage on a typical 10-year-old car still averages $1,935 a year against $991 for liability only, and ValuePenguin reads the same 10-year-old car at $1,758 on a vehicle worth about $5,067. That premium is most of a car payment, on a car that has been shedding value the whole decade. Premiums do fall as a car ages — just far more slowly than the car does.

Try a bigger deductible first

Nobody at your insurer will call to say the coverage stopped making sense three years ago. That call doesn't exist. The renewal shows up, you glance at the total, you pay it.

Dropping coverage is the big lever. There's a smaller one first, and most people never pull it.

Raise your deductible from $500 to $1,000. Published savings run 9% to 25% of the premium: CarInsurance.com measures about 9%, roughly $188 a year; NerdWallet 12.8% across more than 400 million rates; ValuePenguin as much as 25%. The deductible only touches comp and collision, so those are the lines the money comes off. You keep the protection against a total loss. You absorb the first $1,000 yourself.

Break-even at CarInsurance.com's reading is about 2.7 years without a claim. For a car in the awkward middle — too valuable to go uncovered, not valuable enough for a low deductible — that's usually the move.

You can drop one and keep the other

Comprehensive and collision get sold as a pair. They aren't one thing.

Comprehensive averages about $421 a year. Collision, the pricier half, about $473. Comprehensive covers what careful driving can't prevent: theft, hail, a flooded underpass, a deer at dusk. Collision covers crash damage to your own car — the risk that shrinks most if you drive few miles on familiar roads.

United Policyholders, a consumer group with no policies to sell, says drop collision first. That's the order I'd follow.

If another insured driver hits you, their liability still pays for your car. What disappears with collision is the wreck that's your fault, the single-car accident, and the driver with nothing to collect from.

Two timing traps

First, your accident history. One at-fault accident raises premiums 34% to 49% on average, depending on whose rate book you read — WalletHub measures 34%, Bankrate 43%, NerdWallet 48%, ValuePenguin 49%. It rides along for three to five years, with LendingTree reading the short end of that at about three. Dropping comp and collision after a crash still saves money, but it won't put you back at your old number until that surcharge ages off.

Second, the calendar. You almost never have to wait for renewal. Insurers generally let you drop optional coverages mid-term and refund the unused premium. Ask how yours handles it.

Move the old premium into its own account

This is where it usually falls apart.

Someone runs the math, drops comp and collision, clears somewhere in that $828 to $1,476 range, and the money dissolves into groceries and a better phone plan. Eighteen months later, hail comes through and there's nothing behind the decision.

You didn't save that money. You took a job away from the insurance company and handed it to yourself.

So move the old premium into a separate account the day the coverage comes off. That account is your comprehensive and collision now, and it's the only version of this decision that holds up.
