Very nice illustration in Personal Finance Success Comes More From Smart Budgeting Than Smart Investing:
Now, Kevin’s a smart investing cookie and is able to crank out a 16% return each year. I just take my money, dump it in a Vanguard 500, and move on with life, which means over the long haul I earn a 12% return. Who earns more in the long run?
After five years of this same investing, Kevin has $34,385.68 in his investment account, while I have $63,528.47 in mine, a difference of $29,142.79 in the frugal guy’s favor. Even at the twenty five year mark, if the investments have continued for that long, Kevin has $1,246,070.12 in his account, while I have $1,333,338.70 in mine, a difference of $87,268.58.
I would use lower returns (to better match what I think is reasonable to use in projections about the future) but by using higher returns it actually makes a stronger point (the compounding at 16% is extraordinary – I was actually surprised that at the 25 year mark that the results were the way they were). The lesson is powerful. Your personal finance situation is a factor of several things, but very close to the most important is just actually saving money, as the post illustrates.
