If you're carrying collision and comprehensive on a 10-year-old Civic worth $5,000, you might be spending more on insurance than the car would pay out after a total loss. The math eventually flips, and most drivers don't notice.
Here's how to decide when to drop it.
The simple rule of thumb
Add up your annual collision + comprehensive premium. Multiply by 10. If that number is greater than your car's current value, you're probably overpaying.
Example: $700/year in collision + comprehensive on a car worth $4,000. Over 6 years claim-free, you've spent $4,200 — more than the car. And if you DO total it, you'd only collect $4,000 minus your deductible.
The questions to actually answer
1. What is the car worth?
Check Kelley Blue Book private-party value. This is roughly what the insurer would pay in a total loss. Note that older cars in good condition often command 20 to 30 percent more than KBB shows for actual sale prices, but insurers use the more conservative figure.
2. What's your deductible?
If your deductible is $1,000 and your car is worth $4,000, the most you'd ever collect on a total loss is $3,000. That's the practical ceiling on the value of the coverage.
3. What's the actual claim probability?
National averages: roughly 1 in 18 drivers files a comprehensive claim each year, 1 in 22 a collision claim. Multiply by your years of ownership. If your car has been claim-free for 8 years, you've already saved more than the coverage was worth in a typical case.
4. Could you self-replace the car?
If your car is totaled tomorrow, can you write a check for a similar replacement? If yes, you're effectively self-insuring already — the only question is whether the insurer's risk pool gives you a better deal.
When to drop collision but keep comprehensive
Comprehensive (theft, hail, animals, glass, weather) is usually cheaper than collision and protects against things you can't control. For many older cars, dropping collision while keeping comprehensive is the right midpoint.
When to drop both
- Car is worth less than $3,000 to $4,000
- Combined collision + comprehensive premium exceeds 10 percent of car's value annually
- You have enough liquidity to replace the car out of pocket
- The car is a secondary vehicle (you have another car to use)
What you should NOT drop
Liability
Required by California law. Your liability covers damage to OTHER vehicles and people, which is where the catastrophic financial risk lives. Never drop it; always carry more than state minimums.
Uninsured/underinsured motorist
Cheap relative to its value. Especially important in California where uninsured driver rates are high. Keep it at limits matching your liability.
Medical payments / personal injury protection
Pays your medical bills regardless of fault. Cheap, useful, easy to keep.
What to do with the money you save
If you drop collision and comprehensive and save $700 a year, set up a 'car emergency fund' for $1,500 to $2,000 in a savings account. Now you're genuinely self-insured: if something happens to the car, you can repair or replace it without insurance, and you've kept the $700 a year.
Without that emergency fund, you're not really self-insured — you're uninsured.
The annual review worth doing
Every year at renewal, do this 5-minute check:
- Pull your car's current KBB value
- Note your current collision + comprehensive premium
- Calculate premium ÷ value as a percentage
- Above 10 percent: time to consider dropping coverage
