Car Affordability — $100K Salary
How much car can you afford on a $100,000 salary?
Conservative vs. aggressive ceiling
| Rule | Total car budget | Payment ceiling | Max vehicle |
|---|---|---|---|
| 10% rule — conservative | $583/mo | $408/mo | $20,000 |
| 15% rule — standard ceiling | $875/mo | $700/mo | $35,000 |
Vehicle price assumes a 60-month loan at 7.5% APR. Insurance estimated at $175/month. Your actual insurance may vary by state, age, and driving history.
What that payment costs long-term
$700/month invested in the S&P 500 at 10.5% historical average returns grows to $147,570 over 10 years. That is the real price of every car decision — not the payment, not the sticker. The opportunity cost.

Three vehicles at this budget
Safe pick, stretch, and what counts as luxury at $100,000 salary.
Well under your ceiling. The surplus is the point — put it somewhere it compounds.
Inside the ceiling with home charging. Insurance is high — factor that in first.
Technically affordable. Out-of-warranty service costs will change the math.
What if your APR is bad?
Your $700/month ceiling finances different vehicles depending on your rate.
Based on 60-month loan at $700/month payment. A 4-point rate difference costs you $3,156 in buying power.
At $100,000, you earn in the top 20% of US households. Your car payment ceiling is roughly $780/month total. The irony of higher income and car payments: as income rises, the tendency is to fill the payment ceiling rather than stay well below it. The financially optimal move at this income is to drive a car that costs 8-10% of take-home, not 15%, and put the difference somewhere it compounds.
