Finance vs. Cash at $150K Income
Finance vs. cash analysis for high earners at $150K income
| Vehicle Price | Finance Option (7%, 60mo) | Cash Option | Opportunity Cost of Cash vs Finance (7% invest) |
|---|---|---|---|
| $40,000 | $792/month | Pay cash | Cash invested: $65,000 in 10yr; finance is better if invested |
| $60,000 | $1,188/month | Pay cash | Cash invested: $118,000 in 10yr; finance saves more if you invest difference |
| $80,000 | $1,584/month | Pay cash | Cash invested: $157,000 in 10yr; only buy cash if it’s under 5% |
If your auto loan rate is 6% and your investments earn 7%+, financing the car and investing the cash earns slightly more than paying cash. At 8%+ loan rate, paying cash wins. The math is closer than most people expect — the key is actually investing the freed cash, not spending it.
