Fees

If returns are going to be 7 or 8 percent and you’re paying 1 percent for fees, that makes an enormous difference in how much money you’re going to have in retirement.

Higher costs

I think that the people who buy those index funds, on average, will get better results than the people that buy funds that have higher costs attached to them, because it’s just a matter of math.

Index fund

If I were going to put money into an index fund in relatively equal amounts over a 20 or 30-year period, I would pick a fund – and I know Vanguard has very low costs. I’m sure there are a whole bunch of others that do. I just haven’t looked at the field.
