When I first began investing in mutual funds, I felt overwhelmed by all the options. I’d heard of equity funds, bond funds, index funds, and balanced funds, but I didn’t really know how they worked—or how to choose between them. Then I came across a Chegg study guide during a late-night research session, and it broke mutual funds down into five core types. That framework gave me clarity. In this article, I’ll explain those five types in depth using that Chegg-inspired breakdown as a foundation. I’ll share examples, do some math, and offer perspectives rooted in my experience investing in U.S. markets.

Chegg outlines five major types of mutual funds:
- Equity Funds
- Fixed-Income (Bond) Funds
- Money Market Funds
- Balanced Funds
- Index Funds
Each serves a different purpose in a portfolio. I’ll unpack each of them, using illustrations, performance metrics, and U.S.-specific economic context. Let’s begin with the one that gets the most attention: equity funds.
1. Equity Mutual Funds
Equity mutual funds invest primarily in stocks. Their goal is capital appreciation. Within this category, there are several subtypes: growth funds, value funds, sector funds, and market-cap specific funds (like small-cap or large-cap funds).
Growth vs. Value: A Clear Example
Let’s say I invest $10,000 in a growth mutual fund that targets tech companies. The fund holds stocks like Nvidia, Amazon, and Tesla. Assume an average annual return of 12% over 5 years.
Using the compound interest formula:
A = P(1 + r)^tWhere:
- A = final amount
- P = 10,000 (initial investment)
- r = 0.12 (rate of return)
- t = 5 years
So,
A = 10,000(1 + 0.12)^5 = 10,000(1.7623) = 17,623By contrast, a value mutual fund focusing on undervalued blue-chip stocks like Johnson & Johnson or Coca-Cola might earn a steadier 7%.
A = 10,000(1 + 0.07)^5 = 10,000(1.4026) = 14,026U.S. Investor Relevance
In the U.S., many equity mutual funds focus on domestic stocks or sectors like healthcare, financials, or technology. For instance, during the COVID-19 pandemic, I saw healthcare funds outperform broad market indexes.
Equity Fund Comparison Table
| Fund Type | Typical Holdings | Risk Level | Return Potential | Common Use Case |
|---|---|---|---|---|
| Growth Fund | Tech, startups | High | High | Long-term wealth building |
| Value Fund | Blue chips, undervalued | Medium | Medium | Conservative equity exposure |
| Sector Fund | Health, energy, etc. | Varies | Varies | Thematic investing |
| Market-cap Fund | Small/large-cap stocks | Varies | Varies | Size-based strategy diversification |
2. Fixed-Income (Bond) Mutual Funds
Fixed-income mutual funds invest in debt securities. That includes government bonds, corporate bonds, and municipal bonds. The goal is income, not growth.
How Fixed-Income Funds Work
Let’s say I buy into a corporate bond fund that yields 5% annually. If I invest $20,000, I earn:
Interest = Principal \times Rate = 20,000 \times 0.05 = 1,000That’s $1,000 in income each year, typically distributed monthly or quarterly.
Risk and Rate Dynamics
In the U.S., bond prices move inversely to interest rates. When the Fed raises rates, bond fund prices often fall. In 2022, bond funds suffered because of aggressive rate hikes.
| Bond Type | Yield (2024 Est.) | Risk Level | Federal Taxable? |
|---|---|---|---|
| U.S. Treasuries | 4.2% | Low | Yes |
| Municipal Bonds | 3.0% | Low | No |
| Corporate Bonds | 5.5% | Medium | Yes |
| High-Yield Bonds | 7.8% | High | Yes |
I personally use municipal bond funds to shield part of my portfolio from federal income taxes.
Suitability
These funds make sense for retirees, income-seekers, or those looking to balance equity volatility.
3. Money Market Mutual Funds
Money market funds invest in short-term, low-risk securities like Treasury bills and commercial paper. These aren’t for making money—they’re for preserving it.
Example: Emergency Fund Allocation
Suppose I need to park $30,000 for 12 months. A money market mutual fund yields 4.5%.
A = 30,000(1 + 0.045) = 31,350That $1,350 in earnings comes with minimal risk and full liquidity.
Safety and Regulation
U.S. money market funds must comply with SEC Rule 2a-7, which governs maturity limits and credit quality. After the 2008 crisis, regulations became stricter, making today’s funds safer.
Use Cases
- Emergency savings
- Temporary cash parking between investments
- Liquidity reserve in retirement
Money Market Fund Snapshot
| Feature | Description |
|---|---|
| Average Yield | 4%–5% (2024) |
| Risk Level | Very Low |
| FDIC Insurance | No (but historically stable) |
| Minimum Investment | Often $1,000 |
| Typical Expense | 0.10%–0.25% annually |
4. Balanced Mutual Funds
Balanced funds, also called hybrid funds, mix stocks and bonds. These aim to deliver moderate growth with some income and stability.
How the Allocation Works
A typical 60/40 fund might allocate 60% to equities and 40% to bonds. Assume:
- Equity earns 8%
- Bonds yield 4%
So:
Return = (0.60 \times 0.08) + (0.40 \times 0.04) = 0.048 + 0.016 = 0.064 = 6.4%This return reflects the fund’s mixed risk-reward profile.
Example: Vanguard Balanced Index Fund (VBIAX)
I own shares in VBIAX, which tracks the performance of both the CRSP US Total Market Index (stocks) and the Bloomberg U.S. Aggregate Float Adjusted Index (bonds). Its historical annual return over the past decade is around 7%.
When Balanced Funds Help
They work for people who want to “set it and forget it.” These are popular in 401(k)s, IRAs, and target-date funds.
| Allocation Strategy | Equity % | Bond % | Use Case |
|---|---|---|---|
| Conservative | 40% | 60% | Retirees, low risk tolerance |
| Moderate | 60% | 40% | General long-term investors |
| Aggressive | 80% | 20% | Growth-focused investors with long horizons |
5. Index Mutual Funds
Index funds passively track a market index like the S&P 500. They offer low costs and broad diversification.
Real-World Return Calculation
Assume I invest $15,000 in an S&P 500 index fund. If the index grows at 10% per year:
A = 15,000(1 + 0.10)^10 = 15,000(2.5937) = 38,905.50That’s over $23,000 in gains. No active manager tried to beat the market—just steady exposure.
Cost Comparison
| Fund Type | Expense Ratio | Average Annual Return | Manager Involvement |
|---|---|---|---|
| Active Equity | 0.75% | 7%–10% | High |
| Index Fund | 0.04% | 9%–11% | None |
I prefer index funds in my taxable account because they produce fewer capital gains distributions. That’s part of their tax efficiency.
Benefits for U.S. Investors
With index funds, I don’t have to guess which manager will win. I bet on the economy itself. That approach is especially useful in retirement accounts where simplicity matters.
Summary Table: 5 Types of Mutual Funds (Chegg-Style)
| Fund Type | Goal | Risk | Return Potential | Example Use Case |
|---|---|---|---|---|
| Equity | Growth | High | High | Long-term investing, capital appreciation |
| Fixed-Income | Income | Low–Med | Low–Med | Retirement income, portfolio stabilization |
| Money Market | Capital Preservation | Very Low | Very Low | Emergency funds, short-term liquidity |
| Balanced | Growth + Income | Medium | Medium | Simplified retirement investing |
| Index | Market Matching | Medium | Medium–High | Low-cost, tax-efficient diversification |
Final Thoughts
When I invest, I always ask: What’s my goal? Do I want income, growth, or safety? That question helps me decide between these five fund types. Each one aligns with a different purpose, and Chegg’s framework has helped me explain this even to beginners. Whether I’m planning for retirement, saving for a house, or building long-term wealth, I build my mutual fund portfolio using these categories as a blueprint.
