Keep Your Paid-Off Car vs Buy New
Example: Current car value: 8000 $ · Repairs/yr on current car: 1800 $ · New car price: 35000 $ · New car APR: 7 % · New car loan term: 6 yrs · Extra insurance/yr (new): 500 $ · Fuel savings/yr (new): 400 $
| Keeping saves/year | $5,061 |
| Keep: annual cost | $2,200 |
| Replace: annual cost | $7,261 |
| Replacing wins in year | 7 |
Worked example
Keeping an $8,000 car with $1,800/year in repairs costs about $2,200 a year once modest depreciation is added. Buying a $35,000 car at 7% over 6 years runs well over $6,000 a year after the extra insurance, even netting fuel savings. Keeping the old car saves roughly $4,000 annually until repairs climb much higher.
Frequently asked questions
When does replacing finally make sense?
When annual repairs on the old car approach the all-in annual cost of a replacement, or when reliability becomes a safety or income risk. Until then, repairs are usually far cheaper than a new car payment.
Is a $2,000 repair a reason to replace?
Usually not by itself. A single repair is almost always cheaper than a year of new-car payments, insurance, and depreciation. The tool compares ongoing costs, which is the fair way to decide.
How should I value reliability?
If breakdowns threaten your job or safety, add that risk by raising the current car’s repair figure. For most drivers, though, a well-maintained older car remains the budget-friendly choice for years.
