Yeah, $1,000,000 in 40 years is like 250,000-350,000 today.
I would have started my IRA when I was 16, but I was taking several AP classes already, and working the last few hours of free time I had per week to save up for a car.
But if you can do it, start.
I'm going to graduate in December as a computer engineer, and my plan is to invest roughly $25,000 per year until I'm about 35 (13 years). As much as possible would go into 401K to get price matching, so the actual investment may be as low as $15k from my pocket. By the time I reach 35, the investment whould reach about 0.6-1.0 million. At that point, I won't invest anymore into IRAs, 401k, and mutual funds. I'll put it into a house and entertainment. By the time I'm 65, It'll be about 6-10 million dollars, or about 1-3 million today. That's how you become a real millionaire in today's value.
I'm not going to buy a house until I'm married. A house, contrarty to popular belief, is a terrible investment to live in. An efficiency apartment may cost $400/month, but you don't have insurance, $250/month utilities, loads of furniture, property taxes, house repairs, loan interest, etc. A roof repair could cost you $4,000 for instance. That's 1 year at an apartment...
