You make money with investing in two basic ways: your assets grow in value over time, and some assets pay you cash along the way. Stocks have returned roughly 9.8% per year on average since 1926, which means a single $10,000 investment would have doubled about every seven to eight years at that pace. Understanding how those profits actually work, how taxes apply, and how to get started with any budget puts you in a much stronger position than simply picking a stock and hoping for the best.
The Two Ways Investments Pay You
Every dollar you earn from investing comes through one of two channels: price appreciation or income payments. Price appreciation, commonly called a capital gain, happens when you sell an investment for more than you paid. If you buy a share of stock at $50 and sell it at $75, your $25 profit is a capital gain. You don’t actually “make” that money until you sell. A stock can double on paper, but the gain is unrealized until the sale goes through.
Income payments work differently. Many companies distribute a portion of their profits to shareholders as dividends, typically on a quarterly schedule. Bonds pay interest, usually twice a year. Real estate investment trusts (REITs) pass along rental income. With these investments, cash shows up in your account regularly whether or not the price of the asset moves. You can spend that cash or reinvest it to buy more shares, which accelerates your growth over time.
Most investors end up relying on both channels. A diversified stock portfolio might gain 7% in price appreciation and another 2% from dividends in a given year, combining for a total return near that long-run 9.8% average. Neither channel is “better.” Capital gains tend to deliver larger lump sums, while income payments provide steadier, more predictable cash flow.
How Compounding Does the Heavy Lifting
The real engine behind investment wealth is compounding, which means your returns start generating their own returns. If you invest $5,000 and earn 9% in year one, you have $5,450. In year two, that 9% applies to the full $5,450, not just your original $5,000. The difference seems small early on, but it becomes enormous over decades.
At a 9% average annual return, $500 invested every month grows to roughly $92,000 in ten years, $230,000 in fifteen, and over $460,000 in twenty. More than half the balance in that twenty-year scenario comes from investment gains rather than money you actually deposited. The earlier you start, the more compounding works in your favor, because time is the one variable you can’t buy back later.
Where to Put Your Money
Different asset classes offer different combinations of growth potential and risk. Your mix depends on how long you plan to invest and how much volatility you can handle without panicking and selling at the wrong time.
Stocks
Owning shares of companies has historically been the highest-returning mainstream asset class, averaging about 9.8% annually over nearly a century. That average includes crashes, recessions, and recoveries. In any single year, stocks can drop 20% or more, so they reward patience. Index funds and exchange-traded funds (ETFs) let you own hundreds or thousands of stocks in a single purchase, spreading your risk across entire markets rather than betting on one company.
Bonds
Bonds are essentially loans you make to governments or corporations in exchange for regular interest payments. Long-term government bonds have returned about 5.4% annually since 1926. They’re less volatile than stocks, which makes them useful for smoothing out your portfolio’s ups and downs. The trade-off is lower long-term growth.
Real Estate
You can invest in real estate by buying rental property directly or by purchasing REITs, which trade like stocks and give you exposure to commercial buildings, apartments, and other properties without being a landlord. Direct ownership offers rental income plus potential appreciation, but it requires significant upfront capital and ongoing management. REITs offer easier entry and liquidity.
Balancing Risk and Reward
Your asset allocation, the percentage split between stocks, bonds, and other investments, is the single biggest factor in both your long-term returns and how bumpy the ride feels. Financial firms typically define risk profiles on a spectrum. A conservative portfolio might hold only about 20% stocks, with the rest in bonds and cash equivalents. A moderate portfolio lands around 42% to 50% stocks. An aggressive growth portfolio pushes stock exposure to 88% or higher.
If you’re in your twenties or thirties and investing for retirement decades away, a higher stock allocation gives compounding more fuel. If you’re five years from needing the money, shifting toward bonds and cash protects you from a poorly timed market drop. The key is matching your allocation to your actual timeline, not your emotions on any given market day.
Diversification matters within each asset class too. Owning a broad index fund that tracks hundreds of companies protects you from the damage of any single company collapsing. Spreading across U.S. and international markets adds another layer of protection.
How Taxes Affect Your Profits
The government takes a cut of your investment gains, and the size of that cut depends on how long you held the asset. Short-term capital gains, from investments held one year or less, are taxed at your regular income tax rate, which can run as high as 37% at the top bracket. Long-term capital gains, from investments held longer than a year, get preferential rates.
For the 2025 tax year, the long-term capital gains rate is 0% if your taxable income falls below $48,350 for single filers or $96,700 for married couples filing jointly. Above those thresholds, the rate is 15% for most people, climbing to 20% only at very high income levels (above $533,400 for single filers). Qualified dividends, which most dividends from U.S. companies are, get taxed at these same favorable long-term rates.
This tax structure creates a practical incentive to buy and hold. Selling investments within the first year costs you significantly more in taxes than waiting. It also means investing inside tax-advantaged accounts like IRAs and 401(k)s, where gains grow tax-deferred or even tax-free, can meaningfully boost your net returns over time.
Getting Started With Any Budget
You don’t need thousands of dollars to begin. Major brokerages including Fidelity, Interactive Brokers, J.P. Morgan Self-Directed Investing, Public, and SoFi all offer $0 account minimums and commission-free trades. Most of these platforms support fractional shares, which let you buy a slice of a stock or ETF for as little as $1 or $5. If a single share of a company costs $400, you can invest $20 and own a small piece of it.
Opening an account typically takes about 15 minutes online. You’ll need your Social Security number, a government-issued ID, and a bank account to link for transfers. Once funded, you can set up automatic recurring investments, even $25 or $50 per paycheck, so you’re consistently buying regardless of whether the market is up or down. This approach, called dollar-cost averaging, means you buy more shares when prices are low and fewer when prices are high, naturally smoothing your purchase price over time.
Building a Simple Portfolio
You don’t need to pick individual stocks to make money investing. A straightforward approach that works for most people is buying two or three broad index funds: one tracking the total U.S. stock market, one covering international stocks, and one holding bonds. This gives you exposure to thousands of companies and government debt in a few clicks.
If you want even less to manage, target-date funds bundle stocks and bonds into a single fund that automatically shifts toward a more conservative mix as your target retirement year approaches. You pick the fund closest to the year you plan to retire and contribute regularly. That’s it.
The biggest factor in how much money you make isn’t which specific fund you choose or whether you time the market perfectly. It’s how much you invest, how early you start, and whether you leave the money alone long enough for compounding to work. Investors who check their accounts constantly and react to every dip tend to earn less than those who automate contributions and resist the urge to tinker.
