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.
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 cost 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 the moment you drive it off the lot, and another 15% 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 table
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.
