How much car can I afford on a $100K salary?
On a $100K salary ($100,000 a year), keeping every car cost (payment, insurance, fuel and upkeep) to 15% of gross income, or $1,250 a month, you can afford a new car of about $45,000 with 10% down on a 60-month loan at about 7%. Holding to 10% of income, the 20/4/10 rule, it is about $25,000.
The answer
Monthly cost
What a $45,000 car costs each month
| Cost | Per month |
|---|---|
| Loan payment | $876 |
| Insurance | $140 |
| Fuel | $150 |
| Maintenance and repairs | $66 |
| Registration | $8 |
| Real monthly cost | $1,240 |
Lenders only look at the $876 payment, but insurance, fuel and upkeep add $364 a month. The car also loses about $368 a month in value over five years. Out the door with tax and fees it is about $48,750; you put $4,500 down and borrow $44,250.

New or used
How far the budget goes new or used
Used cars cost more to borrow for and to repair, but lose less value. The price limit is for a typical car of that age; whether real models fit depends on what they cost and how cheaply they run.
| Car | Price limit, typical car | Models that fit | Typical rate | All-in per month |
|---|---|---|---|---|
| New | $45,000 | 183 of 361 | 7% | $1,240 |
| 3 years old | $38,000 | 317 of 392 | 9.5% | $1,242 |
| 5 years old | $36,000 | 317 of 363 | 9.5% | $1,247 |
Loan length
How the loan length changes it
Longer loans lower the payment and raise the price you can reach, at the cost of more interest and more time owing more than the car is worth.
| Loan | Price you can afford | Payment | Total interest |
|---|---|---|---|
| 36 months | $29,500 | $901 | $3,254 |
| 48 months | $38,000 | $897 | $5,597 |
| 60 months (assumed) | $45,000 | $876 | $8,322 |
| 72 months | $52,000 | $870 | $11,613 |
