The Real Costof Debt
Average new car loan: $40,657 at 7.1% interest

Before you drive it off the lot,
see what you're really paying.

A car payment isn't just a car payment. It's interest on a depreciating asset, delayed wealth-building, and years of your income locked into something that's losing value every day.

Depreciation Reality Check

You're paying $37,664 for a vehicle that will be worth approximately $14.2K when you finish paying for it — a loss of $23.5K between depreciation and interest.

Cars lose ~15% of value per year. After 5 years, most are worth about half of what you paid.

Opportunity Cost

If your $561/mo payment went into an index fund instead (at 7%/yr), you'd have approximately $1.79M by age 65.

Car Value vs. What You Could Have Built

Your car depreciates while your monthly payment, invested instead, would compound. Same money, very different outcomes.

Investment assumes 7% annual return. Car depreciation assumes ~15%/year. This is illustrative, not financial advice.

Cars have never been this expensive to finance

New car prices surged 44% since 2015. But monthly payments jumped even faster — because interest rates nearly doubled. Even as prices eased from their 2022 peak, payments have barely budged.

Growth since 2015 (indexed, 2015 = 100)

Higher = grown more relative to 2015 baseline

Why payments outpaced prices: The Fed raised interest rates from ~3.8% (2021) to ~6.4% (2024). A car that got cheaper from its 2022 peak still costs more to finance each month.

What car dealers don't tell you

The auto finance industry profits from your lack of information. Here's what to know.

🪤

Monthly payment is a trap

Dealers negotiate monthly payment, not total price. Stretching from 48 to 72 months feels affordable but adds thousands in interest and locks you in while the car loses value.

📉

You're upside-down immediately

A new car loses 15-20% of its value the moment you drive it off the lot. If you financed most of it, you owe more than it's worth for the first year or two.

📐

The 20/4/10 rule

A widely-used guideline: 20% down, loan term no longer than 4 years, and total car costs (payment + insurance) no more than 10% of gross monthly income.

Used cars have better math

A 3-year-old vehicle with 30,000 miles has already absorbed most of its depreciation. You get nearly the same reliability at 50-60% of the new price.

🏦

Get pre-approved before you shop

If you need to finance, get pre-approved at your bank or credit union before stepping into a dealership. This gives you negotiating power and often a better rate.

📈

The opportunity cost is enormous

A $700/month car payment invested for 30 years at 7% turns into $850,000. You might buy a dozen cheap used cars in that time and still come out millions ahead.
