# When Should I Trade in My Car?

Trade in most vehicles when yearly repair costs exceed $1,500, mileage reaches 100,000 to 150,000, or monthly payments climb above $700. These signs show costs often outweigh keeping it.

## Key Signs to Trade In
Here's what you need to know:
- **High repair bills**: Older cars need fixes that add up fast. Expect $1,565 yearly maintenance on pickups after 100,000 miles, per AAA's 2025 study.
- **Mileage milestone**: Many drivers trade at 100,000 to 150,000 miles. Depreciation slows after year five, but fuel and parts rise.
- **Loan or payment shock**: Average new car loans cost $748 monthly, used at $532. Refinance or trade if yours tops $700.
- **Total ownership costs**: AAA data shows $11,577 yearly or $965 monthly for new vehicles at 15,000 miles. Costs drop less for older ones.

## Cost Breakdown Table
Average annual costs from AAA 2025 Your Driving Costs study (15,000 miles/year):

| Vehicle Type | Depreciation | Fuel | Maintenance | Total Ownership |
|---|---|---|---|---|
| Medium Sedan (Gas) | $3,462 | $854 | $898 | $11,577 |
| Compact SUV (Gas) | $3,554 | $898 | $1,121 | $11,577 |
| Medium SUV (Gas) | $4,760 | $1,190 | $1,316 | $11,577 |
| Pickup Truck (Gas) | $6,041 | $1,565 | $1,972 | $11,577 |
