How to Get Started Investing in Index Funds

Trent Hamm

For some of you, this topic will seem almost shockingly trivial, but I have received this question three times now and that, to me, means that a lot of readers are curious about the topic. From the most recent email:

Could you please explain how to begin investing in index funds? I’ve read some of your articles about the benefit of index funds and I’m interested in investing, but I really don’t understand how to get started.

It’s actually not hard at all to get started investing in index funds. First, I’ll discuss how I do it, then I’ll discuss the most common alternative.

How I Do It

As I’ve discussed before, I invest exclusively in Vanguard’s index funds. I’ve read multiple books by John Bogle (or where Bogle was a contributor) and I’ve found that his philosophy – and Vanguard’s philosophy – match quite well what I believe. If you want to get a good grasp of Bogle’s philosophy, try reading either of his books – I’ve reviewed The Little Book of Common Sense Investing here before, but it boils down to seeking ways to invest in a huge variety of stocks as cheaply as you can, and the way to do that is by index funds which are made up of all stocks in a specific class.

So, how did I get started? Basically, I just went to Vanguard and opened an account. They ask for information on your checking account when you create the new Vanguard account. From there, you can manage everything electronically.

For almost every Vanguard fund, the initial cost of getting into that fund directly is $3,000, so I found myself saving my nickels and dimes until I could afford that initial buy-in. The tools that Vanguard provides allow you to make automatic investments in about any way you could imagine – rolling your dividends back into the fund, automatically investing each week or month from your checking account, and so on.

Obviously, you can buy into as many funds as you wish from this one account, each with their own automatic investment plans set up however you like.

Why go this route? The fees for investing directly are quite low – 0.1 to 0.2% of the investment in the fund, which is no problem compared to the returns you can get. Fees on ETFs of Vanguard funds (see below about this) are only slightly lower than that, but that doesn’t include the fees of buying the ETFs or the fees every time you buy more ETFs – this is always a losing proposition if you’re going to invest regularly and your brokerage charges any fees at all. If you want to set up a regular investment plan, doing it directly through your brokerage is the way to go.

Another Route

Another route that many people take is to use a brokerage, like E*TRADE or Schwab or Ameritrade or Scottrade or Zecco. The process for investing this way is very similar – you can sign up online, provide checking account information, and start buying.

With almost all brokerages, however, each time you buy or sell you’re charged some sort of transaction fee. Currently, the only established brokerage that does not charge fees is Zecco, but there are rumblings that they may introduce fees soon. This means that not only do you have to pay the brokerage’s fees, you also have to pay the fees for the company that sets up the mutual fund. So, let’s say you buy a Vanguard fund through Ameritrade – you pay Ameritrade’s transaction fees every time you buy or sell, plus Vanguard’s management fees.

In this situation, one approach is to buy an ETF (exchange-traded fund). ETFs are like stocks that represent a specific set of additional stocks, much like a mutual fund. You can buy and sell them just like any other stock, but their value is pegged to the value of the included stocks. The fees charged for these are usually lower than the same exact index fund would be – for example, the Vanguard 500 (VFINX) index fund has a 0.18% expense ratio (that’s how much Vanguard charges to manage it), while the SPDR 500 (SPY), which tracks the same exact stocks as an ETF, has only a 0.11% ratio.

If you have a fee-free broker (like Zecco is at the moment), it’s more cost-effective to buy the ETFs, but if your brokerage charges any fees at all and you plan on buying more of these regularly, it doesn’t take much at all for those transaction fees to eat any extra gains you might make and more. Here’s the numbers on this very example.

Which Is Right For Me?

If your broker has free trades or you’re planning on buying in only once or extremely rarely, then selling all at once, go through a brokerage and buy ETFs of the indexes that you want. There are a lot of good, reputable brokerages out there who can provide this service for you.

On the other hand, if you’re planning on investing regularly by putting in a small amount each week or month, go directly through the people that run the index fund – in this case, Vanguard. They charge no transaction fees at all on most funds, allowing you to buy in as much as you like as often as you like without worrying about the costs of it.

Generally, I feel more comfortable going directly through Vanguard when buying their index funds for my situations, but that may not be the same for you.

    Thank you very much for writing this post. You are right, more than just the people who wrote to you need this information. Some of us are just getting started.

    I’m planning to go through Vanguard, but I still need that initial $3000 investment. Until then I suppose it’ll go into things like CDs and such to wait. Thanks for posting about this, I had wondered if there was a way around the $3000 but I guess not.

  3. For what it’s worth, here is what I am doing to invest tiny amounts of money and avoid fees. I opened a Schwab One Banking/Brokerage account (free, no minimums) and that allows me to invest in the Schwab One Source funds for no fees (no extra fees, the mutual funds still have their regular fees) and you only need $100 to invest at a time. There is no transaction fee on that $100, which is critical for the small investor (far superior to something like ShareBuilder). The list of funds available for free is somewhat limited, but there are index funds to choose from.

    I’m not trying to sell Schwab to anyone, I’m just sharing what I believe to be a good option for someone who wants to invest small amounts of money.

    Mrs. Micah: Vanguard offers the “Vanguard STAR Fund (VGSTX)” which requires $1000 rather than the usual $3000 to invest. A nice way to get started with them if you don’t have the usual minimum.

  5. LC says:

    I would add that you may also be able to invest in index funds though your company’s 401k.

  6. I always tell newbie investors to start with Fidelity or Vanguard since they have comparatively low fees, and to invest in an S&P 500 Index like VFINX or FSMKX.

    The hard part for them is usually getting enough for the minimum.

  7. JReed says:

    If you automatically invest monthly through TD Ameritrade, there is no fee.

  8. lorax says:

    Besides the ETF transaction fee, there’s also the often overlooked ask-bid spread. This means you can transparently lose .33% on ETF purchases and sales, compared with the same index fund. Of course, this is a one-time hit.

    Many companies that charge no fee for stock/ETF purchases also have very low cash accounts, or require a minimum in a low-interest savings account. You need to make sure you’re really getting a free lunch, not paying for it at the parking meter!

    I’m all about this post. Index funds rule. But I’m a Buffett disciple so I have one stock: a B share of Berkshire Hathaway.

    So while I want to switch my Roth IRA to Vanguard (the best place to be, I admit) from Scottrade, I have to have way more money than I have now ($100,000 I think) to not incur certain annual fees.

    So for now, if I want to have my BRK.B share in there with my other index funds, I’ll be at Scottrade until I break through the six-digit plane.

    T. Rowe Price will let you into their S & P 500 index fund(PREIX) for $50 a month when its in a retirement account. They wave the minimum if you sign up with their Automatic Asset Builder program. I opened up one last month.

    how do you like the service with vanguard? has investing with them been easy?

  12. Chad says:

    A coworker told me that I need to invest in a mutual fund – not an index fund. “You’ll get the dividends with mutual funds but index funds ‘index’ the dividends.” He means you don’t get dividends if you are in an index fund (that has stocks that are paying dividends). Is that true? He says that index funds only make money off the increase in price of the index fund.

    Thanks for posting the article.

    FYI – scottrade waives the $7 trade fees when you buy funs with an IRA account. cachunk.

    From a Canadian…I’ve been researching this topic and I can’t seem to find a Vanguard equivalent here. So, I’ve turned to ETF’s as the next best option [low cost index funds]. Can anyone point me to some good Canadian information on investing in ETF’s or other advice for getting around the high cost Canadian mutual funds.

    Thank you for posting this article. You have provided several good ways to begin understanding and investing in index funds. I have found http://www.marketriders.com to be an excellent approach to these types of investments and is easy to understand for those who have not previously dealt with index funds.
