The 3 Fund Portfolio


The 3 Fund Portfolio is a simple investment portfolio that only contains 3 assets, which are typically equity (stocks) and fixed income (bonds) mutual funds. A three fund portfolio is considered a ‘lazy portfolio’ because it requires very little maintenance. This investment strategy is also simple to implement and is viewed favorably by the investment community which often recommends them as a solid introduction to long term investing.

If you’ve read our guide on asset allocation then you might recognize the phrase 3 Fund Portfolio.

This investment strategy may seem simple, but the underlying principles are solid. It helps you easily create a well-diversified portfolio with low fees (expense ratio).

Let’s jump into what the 3 Fund Portfolio actually is, how it works, and how you can make your own. But first, let’s make sure we are all on the same page.

What’s an investment portfolio anyway? Your portfolio is the collection of assets that you own. If you have all of your investments at Vanguard, then that’s where you’d go to see your portfolio. Yours might even be spread amongst a few different financial institutions.

This is pretty common if you have a 401K from work with one brokerage and your IRA with another one. In that case, you’d want to take a step back and look at your overall investments to see your entire investment portfolio.

Why Investors Love 3 Fund Portfolios

The beauty of the Three Fund Portfolio lies in its simplicity and efficiency. The typical 3 Fund Portfolio contains a U.S. ‘total market’ index fund, an international ‘total market’ index fund, and a bond ‘total market’ index fund.

Investors don’t need to necessarily use mutual funds to construct their portfolio either, as an ETF portfolio offers the same benefits. As a result, the asset classes included in these portfolios are skewed to stocks and bonds. This provides diversified exposure to the stock market. The bond fund adds additional asset diversification and lowers the expected volatility of your simple portfolio.

The weight of each asset will depend on the risk appetite of the investor.

As a refresher, equity index funds are simply investments that are comprised of many different stocks. So by buying a piece of an index, you are actually purchasing small chunks of many different companies. It takes the guesswork out of having to pick individual stocks or trying to beat the market. Even the average professional on Wall Street can’t consistently beat the market, so it’s foolish to think you’ll be able to.

Where Can I Invest?

If you are ready to start investing, but aren’t sure how to get started, the first step is to open an investment account. If you have a job with a retirement plan like a 401k or 403b, you might even already have one.

Another popular retirement account is the IRA. If you prefer, you can also open a standard investment account or taxable account. Common companies where you can open investment accounts include M1 Finance, Robinhood, Webull, and Fidelity.

Once you have the account open and funded, you can select your investments based on your risk tolerance.

Is The 3 Fund Portfolio The Simplest Way To Invest?

If you are looking for the absolute easiest way to invest, you might be interested in learning more about Facet Wealth. They are a fee-only digital financial advisory company. For a fixed monthly fee, they match you with one of their certified financial planners to handle your money for you.

If you want to manage your own investments but want to have an even simpler investment plan, you can invest everything in a single target date fund or target retirement fund. Target date funds automatically adjust their asset allocation to increase the number of bonds that they contain as you approach retirement age. This is simply to lower the risk.

The dirty little secret is that many target date funds are simply the 3 Fund Portfolio masked with a clever name. The nice thing about creating your own 3 Fund Portfolio is that you will have more control and better tax-efficiency than you’d get in a target date fund.

Target date funds also tend to have very conservative allocations, so many people will prefer to have more exposure to stocks (and less to bonds) in order to have a higher chance of generating higher returns over time. Just remember that the market is unpredictable and that historical performance is not an indicator of future performance.

Your Asset Allocation Determines How ‘Risky’ Your 3 Fund Portfolio Will be

Your split between domestic stocks, international stocks, and bonds will determine how risky your portfolio is. The more bonds you have, the less risk you’ll be taking.

We love the advice shared by John Bogle, founder of Vanguard, in his incredible book, with regards to this topic. For younger investors, he recommends investing 80% in stocks and 20% in bonds. He drops this down to 70% stocks for older investors (45yrs +). For those already retired, a split of 60% stocks to 40% bonds might make more sense.

Ultimately, these are only rough guidelines, and you will need to decide what works best for you. If you have a long investment horizon and are less risk-averse, having 95% of your investments in stocks might be right for you. It’s a personal decision that must be made with your investment goals in mind. Think about how you’d react if you were to lose 40% of your portfolio in a short period of time due to a market downturn like in 2008 / 2009. If you think you might panic and sell everything then perhaps having more bonds would help settle your mind (and stomach).

Asset Allocation Pro-Tip: If you decide to invest using only 1 target-date fund, don’t just choose a fund based on your retirement date. Look into the % of the fund allocated to bonds and decide if that’s the mix you feel comfortable with. If you have a target-retirement date of 2045, but like the allocation of the 2055 retirement-date fund better, then go with that.

They are usually pretty good at picking the right year, but it’s always best to double-check. After all, this is your future we are talking about.

Is A 3 Portfolio Great For Everyone?

No, but it would work well for most people. Especially if you want to keep your investments simple. It won’t work well for someone who has absolutely no desire to manage their own investments (nothing other than having someone else take care of it for them will).

It also won’t work for someone who would like to pick individual stocks. A portfolio made up of just 3 individual stocks is considered extremely risky since you’re putting all of your eggs in just three baskets.

The main advantages of the Three Fund Portfolio are its simplicity, low costs, broad diversification, ease of rebalancing, and the fact that it won’t underperform the market (since it’ll track the broader market). If these characteristics are attractive to you as you think about your investments, it’s certainly worth looking into!

You also need to have to be aware of any investment minimums for the funds. Some Vanguard Funds have an investment minimum of $3,000, which means might need $9,000 to invest in order to start with a Vanguard 3 fund portfolio. Alternatively, you can just use ETFs since those don’t have minimums and are traded directly on the exchanges.

Do you want to invest but simply don’t have enough money yet? If you aren’t sure how to save enough to get there, you’ll want to read our step-by-step guide to budgeting. It’ll be your first line of defense when it comes to saving and investing more of your money.


What Is A 3 Fund Portfolio?

A simple investment portfolio that uses only 3 assets. Most commonly, these simple portfolios include a US “total stock market” index fund, an international “total stock market” index fund, and a “total bond market” index fund.

Can I Use A 3 Fund Portfolio If My Investments Are Spread Across Different Accounts?

Yes! You have a couple of options. You can create an overall portfolio so that across all of the accounts you only own the 3 assets. Or you can duplicate your 3 Fund Portfolio in each of your investment accounts. It’s common to have your 401K or 403B and IRAs in different accounts, so you aren’t alone.

Can I Use More Than 3 Assets In My 3 Fund Portfolio?

You can use more investments, but remember that part of the benefit of this strategy is its simplicity.

Can I Include Individual Stock In My Three Fund Portfolio?

Traditional 3 fund portfolios don’t include individual stocks. Instead they include mutual fund or ETF investments which include many different stocks and bonds.

  1. I only started investing a few months ago when I turned 18! I live in Canada and the most tax-advantaged vehicle for people with low incomes is the TFSA since it uses after-tax dollars. Of course, mine is a bit sad right now since there’s only like $1500 in it (university eats up the rest of my money), but I have a four ETF allocation. One, VCN, tracks the Canadian market (it’s about 65% of my portfolio). VFV, which follows the S&P 500, is about 10-15%. I’m aiming to increase its allocation once I can save enough money to buy a share (and yes, I realize how sad that sounds). The rest is split evenly between a developed markets ETF (XEF) and a bond ETF (ZAG). It’s a very aggressive portfolio, but since I’ll only need it in a few decades I figure I had the time. That being said, any advice? I’m a bit caught between saving for the near future (in case tuition increases or something like that) and investing in my TFSA. I mean, I have a 12-month emergency fund but half of that is tied up in a GIC ladder, most of which will mature in less than a year. I don’t exactly have a job, so the lack of income is what’s pushing me to squirrel everything into savings. Do you think I’m maybe being a bit too excessive? Most of my money is coming from participating in studies since it’s more flexible and I can choose the hours.

    • Congrats on the amazing progress even though you are only 18. I know it may feel like you aren’t doing enough and it can be stressful, but believe us… you are going to be WAYYY ahead of your peers. With regards to your question, your allocation seems fair. Yes, it’s aggressive, but you have time on your side. We are less familiar with VCN but since you live in Canada, it makes sense to invest in canadian dollars. The lack of an income is due to being in college? If so, that makes sense. Continue to do what you are doing. Save as much as you can while still leaving yourself a buffer in case of an emergency. Focus on your academics so that you can get your ideal job. Remember, life is a marathon, not a sprint. Out of curiosity, where’d you learn about personal finance so young? Well done!

  2. Hi Camilo and Francisco! I’m 27 years old, a college graduate, and very new to investing. I haven’t managed my money well, however I am motivated to do things differently with ambitious hopes of being financially free. As we speak, I have a mere $393.47 in my bank account. My top priority is paying down my high-interest credit cards, but I opened a Brokerage Account and Roth IRA Brokerage Account with Vanguard last week. Just to dip my toes in, I put $10 in each account. I know how meager this sounds, but I’m determined to work with what I’ve got and improve as I go. As you mentioned, I would need at least $9,000 to invest in a three fund portfolio using Vanguard Index Funds. Realistically, I won’t have that money for a while. However, I could do the all-in-one Target Retirement Fund for $1,000. It seems I could also invest in the three fund portfolio using Vanguard ETFs for even less. I’m still learning the difference between ETFs and Mutual Funds, and I’m not sure what the difference is when buying stocks/bonds with money in the Brokerage Account versus the Roth IRA Brokerage Account. All in all, I’m wondering if you have thoughts about me investing in the Target Retirement Fund versus a three fund portfolio with ETFs? I also welcome any other thoughts or feedback.

    I learned of you from the podcast Optimal Finance Daily, and it’s changed my outlook for the better. Thank you, Finance Twins!

    • Hey Heatherlee, thanks so much for reading. There’s a lot of info in your comment, so I hope we answer all of your questions. To start, you said you have both a brokerage account and an IRA. Both are accounts used to make investments, but there’s a few differences between them. The standard brokerage account is a taxable account, which means any profits realized will be taxed as capital gains. There are also no restrictions on how much you contribute or when you decide to withdraw that money from a taxable account. The IRA, on the other hand, is specifically for saving for retirement. For that reason it offers tax savings that the normal account doesn’t offer. The caveat is that there are some restrictions around how much you can contribute to the account annually and when the money can be withdrawn penalty free. More details about IRAs can be found in this article: . What you ultimately decide to invest in within those accounts depends on a few things. If you aren’t that excited or passionate about doing the investing on your own, the target date fund is great because you kind of set it and forget it. You just have to continue to regularly invest and put more money into it. Just make sure you aren’t paying a ton of fees. Vanguard funds are great.

  3. Hello,
    Thank you for a great article and helping with investing. I’m new to invest and try to decide if I should pick Vangard etf or Blackrock ishares. Really not sure which one I should pick.?

    • compare and see which has a lower expense ratio. if they track the same index, then lower fees will mean you keep more of your money, all else equal.

  4. Great article! I like M1 Finance so would you suggest using a pie there, or better to go straight to Vanguard (assuming I am using their ETFs)? My thoughts are it would be the same but making sure I am not wrong.
    Also, what are your thoughts on VT instead of VTI+VXUS? That way it could be even simpler with 2 funds (VT + BND).

    • I think you can use a pie there. I personally have used M1 and think it kind of encourages more individual stocks just based on the ease of creating a pie. But if you have the discipline, I think it’s okay! VT has ~40% exposure to rest of world, so you just have to make sure you are comfortable with that.
