Saving Early Really is KEY!

Alright, shoot me, I don't have an exact source for this.  It's from the Washington Post; that's all I can give you.

But I thought this information was so staggering that I just had to post it:

a 25 year old who invests $2,000 each year for 40 years... total investment: $80,000... yield at age 65 assumed a 10% return: $973,704
a 35-year old invests $2000 each year for 30 years.... total investment: $60,000... yield at age 65 assuming a 10% return: $361,887

25 year old invests $2,000 each year for 8 years and nothing more for 32 years.... total investment: $16,000... yield at age 65 assuming a 10% return: $531,200
35 year old invests $2,000 each year for 30 years... total investment: $60,000... yield at age 65 assuming a 10% return: $361,887

$973,704?  Holy hell!  Why haven't I started a Roth IRA yet? 
Maybe I'd feel better about it if I had an extra $2,000 just lying around!
