Best Index Funds for Beginners with Low Fees in 2025

Walking into the world of investing for the first time can feel like stepping onto a trading floor in a new language. But here’s the good news: you don’t need to be a Wall Street pro to build real wealth. In fact, the smartest move for most beginners is to start with the best index funds for beginners with low fees. These funds mimic broad market performance, cost next to nothing to own, and let time do the heavy lifting.

As of 2025, the investing landscape offers more low-cost passive investing options than ever. Whether you have $50 or $5,000 to start, this guide will help you pick the right funds, avoid common mistakes, and keep more of your money working for you.

Why Index Funds Are a Beginner’s Best Friend

Index funds are essentially diversified baskets of stocks or bonds that track a specific market index—like the S&P 500. Instead of hiring expensive managers to pick individual stocks, these funds simply mirror the market. And research consistently shows that most active managers fail to beat the market over the long term.

For beginners, low-cost index funds offer three game-changing advantages:

Instant diversification: One fund can hold hundreds or thousands of securities across sectors.
Ultra-low fees: Expense ratios often sit below 0.10%—compared to 1% or more for actively managed funds. Low expense ratios maximize your returns over time.
Hands-off simplicity: No need to research companies or time the market. Just buy and hold for long-term growth.

In fact, legend Warren Buffett has repeatedly recommended low-cost index funds as the best option for most investors. He famously bet $1 million that an S&P 500 index fund would beat a basket of hedge funds over ten years—and he won handily.

What to Look for in the Best Index Funds for Beginners with Low Fees

Before we dive into specific funds, let’s set the criteria. Not all index funds are created equal. Here’s what matters most for smart investing:

Expense Ratio: The Fee That Compounds

The expense ratio is the annual fee the fund charges as a percentage of your investment. For example, a 0.03% expense ratio means you pay $3 per year for every $10,000 invested. Over 30 years, a 1% difference in fees can cost you tens of thousands of dollars. Stick to funds with expense ratios below 0.10%, especially when comparing low-cost index funds.

Minimum Investment

Some funds require $1,000 or more to start. But many brokerages now offer fractional shares and no minimums. Look for funds that let you start small.

Index Tracked

Choose funds that track broad, well-established indexes like the S&P 500, CRSP US Total Market Index, or Bloomberg US Aggregate Bond Index. Avoid niche or leveraged indexes—they add unnecessary risk and complexity. [INTERNAL_LINK: understanding index fund types]

Top 5 Best Index Funds for Beginners with Low Fees in 2025

Based on fees, performance history, and accessibility, here are the standout options for new investors. All of these offer affordable investing with top-tier diversification features.

1. Vanguard S&P 500 ETF (VOO)

Expense ratio: 0.03%
Minimum investment: Price of one share (around $450 in early 2025, but many brokers offer fractional shares)
Why it wins: Tracks the S&P 500, which has historically returned about 10% annually. VOO gives you ownership in 500 of America’s largest companies, from Apple to Johnson & Johnson. Its expense ratio is among the lowest in the industry.

Example: If you invest $200 monthly in VOO for 30 years with an 8% annual return, you’d accumulate over $280,000—even after fees.

2. Fidelity ZERO Total Market Index Fund (FZROX)

Expense ratio: 0.00%
Minimum investment: $0
Why it wins: That’s right—zero fees. Fidelity’s ZERO series is designed to make investing accessible for beginners. FZROX covers the entire U.S. stock market, including small, mid, and large caps. It’s available exclusively through Fidelity accounts.

Pro tip: While the expense ratio is $0, there are no transaction fees either. Just be aware that you can’t transfer this fund to another brokerage—so keep it inside your Fidelity account.

3. Schwab U.S. Broad Market ETF (SCHB)

Expense ratio: 0.03%
Minimum investment: $0 (with fractional shares on Schwab)
Why it wins: SCHB offers a total stock market strategy in one low-cost ETF. With over 2,500 holdings, it’s as diversified as you can get in a single fund. Schwab’s platform is beginner-friendly with educational tools for passive investing.

4. iShares Core S&P Total U.S. Stock Market ETF (ITOT)

Expense ratio: 0.03%
Minimum investment: Price of one share (typically around $100)
Why it wins: ITOT covers the entire U.S. equity market, from mega-caps to micro-caps. It’s a favorite for those who want total market exposure in a single ETF. BlackRock, the issuer, is one of the largest asset managers globally.

5. Vanguard Total Bond Market ETF (BND)

Expense ratio: 0.03%
Minimum investment: Price of one share
Why it wins: Why include bonds in a beginner’s list? Because a balanced portfolio reduces risk. BND tracks the entire U.S. investment-grade bond market, providing steady income and stability. As you age, bonds become more important for preserving capital.

Practical example: A classic “60/40” portfolio (60% stocks like VOO, 40% bonds like BND) has historically provided strong returns with less volatility than a stock-only approach.

How to Start Investing in These Funds

You don’t need a financial advisor or a fat bank account. Here’s a step-by-step plan:

Open a brokerage account—Fidelity, Vanguard, Schwab, or a robo-advisor like Betterment are all solid choices for affordable investing.

Decide on your allocation—For beginners, a simple two-fund portfolio (e.g., 80% VOO + 20% BND) works well.

Set up automatic investments—Most platforms let you automate monthly contributions. This builds consistency and removes emotion.

Ignore the noise—Don’t check your balance daily. Markets go up and down, but history shows staying invested over long periods yields positive returns.

Frequently Asked Questions

What is the best index fund for a complete beginner with low fees?

Should I choose an ETF or a mutual fund?

For beginners, ETFs (like VOO or SCHB) are often easier to buy and sell with no minimums. Mutual funds (like FZROX) might offer fractional shares too. Both work well for passive investing.

Are index funds safe for beginners?

Index funds are not risk-free, but they are among the safest ways to invest in the stock market because of diversification. Over long periods (10+ years), they historically produce positive returns for investors who stay patient.
