The car decision.
One of the biggest wealth levers of your 20s.
The average new car payment in 2026 is over $730/month. That single decision, new vs used, lease vs buy, $500/month vs $200/month, can mean a $500,000+ difference in lifetime wealth.
Check the written offer
Get the itemized out-the-door price in writing before discussing a monthly payment. Separate the car price, taxes, mandatory fees, optional add-ons, down payment and any trade-in loan balance. Compare offers using the amount financed, APR, term, finance charge and total of payments, not payment size alone. Longer terms can lower the payment while increasing total borrowing cost.
Use the CFPB auto-loan comparison to check disclosures against the buyer’s order and contract. Ask which add-ons are optional and whether their cost is financed. A calculator cannot verify the seller’s charges or the condition of the car.[1]
Check before acting. Rates, prices, fees and product terms change often. Confirm the current figures with the provider or the linked source before you act.
This page covers what to buy and how much to spend. For negotiating price, trade-in and financing at the dealership, see How to Buy a Car; to run your own numbers, use the Auto Loan & Lease vs Buy Calculator.
Get the itemized out-the-door price in writing before discussing monthly payments. Then apply the 20/4/10 rule: at least 20% down, a loan of 4 years or less, and total car costs under 10% of gross monthly income. A 2 to 3 year old used car skips the steepest depreciation.

The true cost of car ownership
The sticker price is not the cost. The real cost includes depreciation (the biggest expense by far), insurance ($1,500–3,000/year for young drivers), maintenance and repairs, fuel, registration, and the opportunity costopportunity costWhat you silently give up when you pick one option over another. Spending $100 today on dinner means giving up whatever that $100 could have grown into if you had invested it instead.Full definition of the down payment. A $35,000 car costs roughly $55,000–65,000 over 5 years of ownership when you add everything up.
New vs used: the depreciation curve
A new car loses roughly 20% of its value in the first year, and another 15% of what is left in year two. By year five, most cars are worth 40–50% of their original price. Buying a 2–3 year old certified pre-owned vehicle lets someone else absorb the steepest depreciation.
Lease vs buy: the honest math
Leasing feels cheaper because the monthly payment is lower. But you never build equity, you pay mileage penalties, and you are locked into a new lease every 3 years, permanently. The person who buys a reliable used car and drives it for 8–10 years pays dramatically less per year of transportation than someone who leases a new car every 36 months. Leasing is almost never optimal for wealth building.
The 20/4/10 rule
20% down payment minimum. 4-year maximum loan term. 10% of gross monthly income as the ceiling for total car costs (payment + insurance + fuel). If you cannot meet all three, the car is too expensive.
The opportunity cost
At age 22, investing $300/month instead of spending it on a car payment, compounding at 10% for 40 years: $1,897,000. That is almost $2 million, the difference between a $500/month car payment and a $200/month one, invested over a career.
Bitcoin angle: $15,000 into a new car at 22 vs $15,000 into Bitcoin at the same age. If Bitcoin compounds at even 15% annually for 20 years, that $15K becomes $245,000. The car is worth $2,000.
