Choosing the right mutual funds to invest in can feel overwhelming when you’re opening your first Vanguard account. With dozens of options available, it’s easy to assume you need a long list of funds to build a successful portfolio. In reality, a handful of low-cost, diversified funds can provide everything most beginners need.
Vanguard has built its reputation on simple, affordable index investing. Founded by John C. Bogle, the company pioneered the index mutual fund and continues to offer some of the lowest-cost investment options available. While many of its Admiral Shares require a $3,000 minimum investment, they remain among the most popular choices for long-term investors.
This guide covers the best Vanguard mutual funds to invest in, what each fund is designed to do, and how to decide which one fits your investing goals.
Why Vanguard Is Popular Among Long-Term Investors
Vanguard operates differently from many other investment companies. Rather than being owned by outside shareholders, the company is owned by its funds, which are owned by investors. This unique structure helps keep expenses low, allowing investors to keep more of their returns over time.
One important thing to know is that most Admiral Shares require a minimum initial investment of $3,000. If that’s more than you’re ready to invest, Vanguard also offers ETF versions of many of these funds that can often be purchased with much smaller amounts.
Best Mutual Funds to Invest In for Building a Strong Portfolio
The following Vanguard funds have become favorites among long-term investors because they provide broad market exposure while keeping costs extremely low.
Vanguard 500 Index Fund (VFIAX)
VFIAX tracks the S&P 500, giving investors exposure to 500 of the largest publicly traded companies in the United States.
This fund traces its roots back to the original index mutual fund introduced by Vanguard in 1976. It has become one of the most widely held investment funds in the world.
Key features include:
- Tracks 500 large U.S. companies
- Expense ratio of just 0.04%
- $3,000 minimum investment
- Excellent choice for long-term growth
For many investors, VFIAX serves as the core of their portfolio.
Vanguard Total Stock Market Index Fund (VTSAX)
When discussing the best mutual funds to invest in, VTSAX is almost always part of the conversation.
Instead of focusing only on large companies, VTSAX owns nearly the entire U.S. stock market, including large-cap, mid-cap, and small-cap stocks.
Major holdings include companies like Apple, Microsoft, and Amazon, while also providing exposure to thousands of smaller businesses.
Benefits include:
- Broad diversification across the U.S. market
- Approximately 0.04% expense ratio
- $3,000 minimum investment
- Suitable as a single-fund portfolio for many investors
Many experienced index investors consider VTSAX the one fund they would own if they could only choose a single investment.
Vanguard High Dividend Yield Index Fund (VHYAX)
Investors looking for regular income may prefer VHYAX.
Rather than emphasizing fast-growing companies, this fund focuses on established businesses that consistently pay above-average dividends.
Highlights include:
- Hundreds of dividend-paying U.S. companies
- Expense ratio of approximately 0.08%
- Designed for investors seeking income alongside growth
- $3,000 minimum investment
Dividend-focused investing often becomes more attractive as investors move closer to retirement or want additional cash flow from their portfolios.
Vanguard Total International Stock Index Fund (VTIAX)
Many beginners invest only in U.S. companies, but international diversification can help reduce country-specific risk.
VTIAX provides exposure to more than 8,000 companies outside the United States, including businesses in both developed and emerging markets.
The fund includes well-known international companies such as:
- Taiwan Semiconductor
- Samsung
- Nestlé
- Toyota
- ASML
With an expense ratio of around 0.09%, VTIAX offers global diversification at a relatively low cost.
Although international markets have trailed U.S. stocks in recent years, many investors include VTIAX to avoid relying entirely on one country’s economy.
Vanguard Total Bond Market Index Fund (VBTLX)
Stocks generally produce higher long-term returns, but they also experience significant volatility.
VBTLX provides stability by investing in thousands of investment-grade U.S. government and corporate bonds.
Its main characteristics include:
- Broad U.S. bond market exposure
- Expense ratio of approximately 0.04%
- $3,000 minimum investment
- Lower volatility than stock funds
Younger investors may choose to hold little or no bonds, while those approaching retirement often increase their bond allocation to reduce overall portfolio risk.
Vanguard Target Retirement Funds
For investors who prefer simplicity, Vanguard’s Target Retirement Funds combine multiple investments into one fund.
Each target-date fund includes:
- U.S. stocks
- International stocks
- Bonds
The fund automatically adjusts its asset allocation over time, gradually becoming more conservative as the selected retirement year approaches.
Advantages include:
- Automatic portfolio rebalancing
- Diversification in one investment
- Expense ratio around 0.08%
- Minimum investment of $1,000
These funds are popular among investors who want a “set it and forget it” approach without managing multiple holdings.
How to Choose the Right Mutual Funds to Invest In
Choosing between these mutual funds to invest in depends on your goals rather than trying to find a single “best” option.
Here are some common approaches:
- Choose VTSAX if you want exposure to the entire U.S. stock market.
- Choose VFIAX if you prefer investing specifically in the S&P 500.
- Add VTIAX if you want international diversification.
- Add VBTLX as you get closer to retirement or want a more stable portfolio.
- Consider VHYAX if dividend income is an important goal.
- Select a Target Retirement Fund if you want one professionally managed investment.
Many beginners make the mistake of buying several funds that own many of the same companies. While it may appear diversified, holding overlapping funds often provides little additional benefit.
Instead, focus on selecting funds that each serve a different purpose within your portfolio.
Final Thoughts
The best mutual funds to invest in are not necessarily the ones with the highest recent returns. More often, they are low-cost, diversified funds that you can confidently hold through market ups and downs.
Whether you choose VFIAX, VTSAX, or a Vanguard Target Retirement Fund, consistency is usually more important than constantly chasing the latest investment trend. Building wealth typically comes from investing regularly, keeping costs low, and staying invested for decades rather than trying to predict the market’s next move.
