With index funds, do you need a financial advisor?

In the most recent issue of Money, Walter Updegrave answers a reader's question about whether, given the prevalence of low-cost market-tracking index funds, a financial adviser is really necessary.

Good question! Updegrave explains the benefits that a financial advisor can provide: How much do you need to save? Which index funds should you buy? What about rebalancing?

He's not wrong about any of these ideas, but the reality is that, if your retirement savings are as paltry as most Americans, the benefits of paying a fee-only financial advisor (the only kind you should work with) are likely to be completely our of proportion with the benefits.

If you have $5,000 to invest and spend even $100 on a financial advisor, that's the equivalent of a 2% front-load. That can be pretty hard to overcome, and it's unlikely that a financial advisor will provide enough benefit to make it preferable to going it alone after doing your own research.

If you're a young worker just getting started on the whole idea of retirement planning, a financial advisor is probably a luxury that doesn't make any sense.

Here are some great books that you can get at the library that should make up for it: Yes, You Can Get a Financial Life!, The Only Investment Guide You'll Ever Need, and The Money Book for the Young, Fabulous, and Broke.
