Is your car worth fixing?
Enter the repair quote and what the car is worth. We apply published rules of thumb to your numbers and show every step, with no hidden market prices.
Result
Enter the repair estimate and the car’s value, then tap Check my numbers.
This calculator only uses the numbers you enter. It doesn’t look up prices or value your car. The rules of thumb are guidance from the sources linked in the result, not a guarantee, and they aren’t legal, insurance or financial advice. If your insurer is handling the claim, it decides whether the car is a total loss.
How the calculator works
We don’t look up or guess what your car is worth. You enter the value, so the result is only as good as that number. Here’s exactly what the calculator does with it:
- Cost-to-value ratio: the repair estimate divided by the car’s value once repaired. If you enter a range, the high value gives the lower ratio and the low value gives the higher ratio.
- The 50% rule: at 50% or more, the result recommends you seriously consider replacing the car (AAA SoCal, “To Repair or Replace” (Feb. 12, 2009); AAA Club Alliance gives the same advice: AAA Club Alliance, “Should You Repair or Replace?”).
- Over 100%: the repair costs more than the car will be worth, so selling or junking it usually makes more sense. For comparison, Texas treats a damaged vehicle as salvage when repairs exceed its actual cash value (Texas Transportation Code §501.091(15)).
- Value left after repair: the value minus the repair cost. If you enter a cash offer for the car as it is, the calculator compares the two.
- Monthly comparison: if you enter how long you’d keep the car, the repair cost is divided by those months, the test Consumer Reports, “Consider Fixing the Car You Already Own” (updated Jan. 29, 2026) suggests, and compared with a replacement car payment if you enter one.
- Age: the car’s age compared with the average age of US light vehicles, 12.8 years in 2025 (S&P Global Mobility, average US vehicle age 2025 (May 21, 2025)). This is context, not a verdict.
- Condition and mileage: rough or damaged cars get a reminder that AAA advises making a major repair only if the car is otherwise in good condition. Cars over 100,000 miles get a note that mileage alone isn’t a reason to junk.
Rules of thumb, explained
The 50% rule
AAA’s long-standing advice: “When the cost of a needed repair approaches 50 percent of the vehicle’s value, it is time to seriously consider replacing it” (AAA SoCal, “To Repair or Replace” (Feb. 12, 2009)). AAA also points out that repairing the car you own is usually cheaper in the long run, so the 50% line is a point to stop and think, not an automatic reason to junk.
Divide the repair by the months you’ll keep it
Consumer Reports suggests comparing a repair with a car payment: divide the repair cost by the number of months you expect to keep the car. CR adds that paying a $3,000 repair bill is probably a better financial move than committing to a $500 monthly car payment over the next several years, before counting sales tax, registration fees and likely higher insurance on a newer car. If your car is chronically in need of repairs, though, it may be time to replace it (Consumer Reports, “Consider Fixing the Car You Already Own” (updated Jan. 29, 2026)).
Reliability matters more than one number
AAA says the decision to make a major repair “should always be based on knowing the vehicle is otherwise in good condition and likely will not require additional major repairs anytime soon.” A history of problems can mean more costly repairs ahead. If you still owe more on the loan than the car is worth, replacing it can mean rolling that negative equity into the next loan.
How states define a total loss
If insurance is involved, the insurer decides whether the car is a total loss. State laws set different lines. Here are two examples from official statutes:
| State | Rule | Source |
|---|---|---|
| Texas | A “salvage motor vehicle” is one whose repair cost (parts and labor, excluding repainting and sales tax) exceeds its actual cash value immediately before the damage. | Texas Transportation Code §501.091(15) |
| Florida | An uninsured damaged vehicle is a total loss when the repair cost is 80% or more of the cost of replacing it with a vehicle of like kind. A vehicle 10 or more model years old valued under $1,000 can be a “derelict motor vehicle”. | Florida Statutes §319.30 |
Other states use different percentages or a formula. Check with your insurer or your state’s motor vehicle agency.
If you decide to junk it
- Get more than one offer. Enter the best one in the calculator’s optional field to see whether it beats repairing.
- Have the paperwork ready. Most buyers want the title. If you don’t have it, read how to sell a junk car without a title.
- Clear out the car. Remove personal items and the license plates, and follow your state’s rules for canceling the registration and insurance.
- Arrange the pickup. If the car doesn’t run, it needs towing. We can pass your request to local providers.
Frequently asked questions
What is the 50% rule for car repairs?
It’s a rule of thumb: when a repair costs about half of what the car is worth, seriously consider replacing the car instead. AAA has given this advice for years. It’s a starting point, not a hard cutoff. A reliable car that needs one big repair can still be worth fixing at 55%, and a car with a history of problems may not be worth fixing at 40%.
Which value should I use, trade-in or private party?
Use what the car would be worth once the repair is done, because that’s what you’d have after paying for it. Valuation sites like Kelley Blue Book and Edmunds show a trade-in value (usually the lowest) and a private-party value (usually higher). If you’re not sure, enter both as a range and the calculator will show the result for each.
How do I value a car that doesn’t run or is damaged?
Edmunds doesn’t publish values for damaged cars. It suggests taking the value in average condition and subtracting what it would cost to restore the car to that condition. For this calculator, enter the value in average (or the expected post-repair) condition as the value and the restoration cost as the repair estimate.
Is my car a total loss if repairs cost more than it’s worth?
If an insurance company is paying, the insurer decides, using its policy and your state’s rules. State definitions vary. Texas calls a damaged vehicle salvage when repair costs exceed its actual cash value, and Florida treats an uninsured damaged vehicle as a total loss when repairs reach 80% of the cost of replacing it. This calculator doesn’t make that call. It only shows how your numbers compare.
Can I junk a car without the title?
Sometimes, depending on your state and the car’s age. Texas, for example, lets a licensed recycler buy a vehicle without a title if it’s at least 13 years old and hasn’t been registered for 7 years. Our guide on selling a junk car without a title explains your options.
Does high mileage mean I should junk the car?
Not on its own. AAA notes that, with proper maintenance, modern cars can be safely driven far beyond 100,000 miles. The car’s repair history and overall condition matter more than the number on the odometer.
