How can I buy a low fee mutual fund?

What fund is good to buy?
and how can I buy it?

I like Vanguard.com for mutual funds, other people like Fidelity, TIAA-CREF, and DFA. Buy no-load, low cost funds. If you are like most people you will invest part of your money aggressively in stock funds, and part conservatively in money market funds and bond funds. Vanguard.com has an on-line questionnaire which will give you an idea how aggressive you want to be.

If your company offers a 401K plan at work, try to invest the most you can. The money grows tax free, and some companies will match your contribution. Investing in a mutual fund IRA is also a good idea.

I like index funds. Because of their broad diversification, you are less likely to have a dramatic drop in value. They also have the lowest expenses. For stock funds, I would suggest putting ~70-80% of your money in the Vanguard Total Stock Market Index Fund. and ~20-30% in a foreign stock index fund. However, there are many different opinions out there on what the best mutual funds are. Read the links below and form your own opinion

If you have high-interest debt, like credit cards, it is best to pay this off first before trying most of the investment ideas above. You should also have 3-6 months of salary saved up as an emergency fund in a bank or money market fund before trying more risky investments.

Believing advice you get on Yahoo answers can be risky, so read these websites for further information. If you find it too confusing, contact a professional financial advisor. They will charge you significant commissions, however.

Call the plan sponsor (i.e. Fidelity, Vanguard, T.Rowe Price) and ask for an application. Fill it out and mail them a check.

I'd recommend the Vanguard SP500 index fund for a beginner. It's performance will almost match the market, and it has one of the lowest fees of all the mutual funds.
