The three ways you actually make money from stocks

You make money in the stock market in two ways: dividends (cash payments companies send to shareholders) and capital gains (profit when you sell a stock for more than you paid). A third source is reinvested dividends, where you use dividend payments to buy more shares instead of taking the cash.

Most people focus on capital gains — buying a stock at $50 and selling it at $75. But this requires timing the market correctly, which is difficult even for professionals. Dividends arrive whether the stock price rises or falls, which is why many savers use them as a steady income source. The trade-off is that dividend-paying stocks often grow more slowly than growth stocks that reinvest profits back into the business.

Your actual return depends on three things you control: how much you invest, how long you hold, and what fees you pay. Your return also depends on one thing you cannot control: what the market does. A stock that pays 3% in dividends but falls 20% in price still leaves you down 17% overall.

Key Takeaways

  • You earn money through dividends (regular cash payments) or capital gains (selling for more than you paid), and most people need both to build wealth.
  • Index funds and ETFs spread your money across hundreds of stocks, reducing the risk of picking individual companies that fail.
  • Brokerage accounts have no contribution limits but offer no tax breaks, while 401(k)s and IRAs limit how much you can add each year but let earnings grow tax-deferred.
  • Costs matter: a fund charging 0.03% annually costs far less over 30 years than one charging 1%, even if both earn the same returns.
  • Time in the market beats timing the market — starting with $100 per month at age 25 builds more wealth than waiting to invest a lump sum at 35.

Individual stocks versus funds: which route fits your situation

Picking individual stocks means researching companies, reading financial statements, and monitoring news. If you enjoy this and have time, you might beat the market. Most people do not. Studies show that 80% to 90% of professional fund managers fail to beat a simple index fund over 15 years. Individual investors, who lack the research tools and time that professionals have, underperform even more.

An index fund or exchange-traded fund (ETF) buys hundreds or thousands of stocks at once. The S&P 500 index fund, for example, owns a piece of 500 large U.S. companies. You own all of them with one purchase. If one company fails, it is a small dent. If you pick one stock and it fails, you lose that money. Index funds cost less to own (often 0.03% to 0.10% per year) because no one is actively choosing which stocks to buy.

Start with index funds or ETFs if you are new to investing, have less than $10,000, or do not want to spend hours researching. Move to individual stocks only if you have money left over after maxing out retirement accounts, you understand the company's business, and you can afford to lose that money without changing your life.

Where to hold your stocks: taxable accounts versus retirement accounts

A brokerage account (also called a taxable account) has no rules. You can add as much as you want, withdraw whenever you want, and buy or sell anything. The catch: you pay income tax on dividends and capital gains every year, even if you do not sell. If you earn $500 in dividends, you owe tax on that $500 immediately.

A 401(k) is offered through your employer. You contribute money before taxes are taken out, which lowers your taxable income that year. Your money grows without being taxed each year. When you withdraw in retirement, you pay income tax then. For 2024, you can add up to $23,500 per year (or $30,500 if you are 50 or older). If your employer matches contributions, that is assistance programs — contribute enough to get the full match before opening any other account.

A traditional IRA works like a 401(k): you get a tax deduction when you contribute, and you pay tax when you withdraw. A Roth IRA is the opposite — you contribute after-tax money, but withdrawals in retirement are tax-free. For 2024, you can add $7,000 per year to an IRA (or $8,000 if you are 50 or older), but income limits apply to Roth contributions. Max out a 401(k) match first, then a Roth IRA if you may have access to, then a traditional IRA or brokerage account.

How costs and fees eat into your returns

A fund charging 1% per year sounds small. Over 30 years, it is not. Imagine you invest $10,000 in two index funds that both earn 8% annually. One charges 0.05% per year, the other 1%. After 30 years, the low-cost fund grows to roughly $100,600. The high-cost fund grows to roughly $73,500. The difference is $27,100 — money that went to fees instead of your pocket.

Check the expense ratio before buying any fund. It is listed in the fund's prospectus and on the brokerage website. For index funds, look for expense ratios under 0.20%. For actively managed funds (where a manager picks stocks), anything under 0.75% is reasonable. Avoid funds charging over 1% unless you have a specific reason.

Also watch for trading commissions (fees to buy or sell) and account minimums (the smallest amount you must deposit to open an account). Most major brokerages (Fidelity, Vanguard, Charles Schwab, E-Trade) charge zero commissions and have no minimums. Avoid brokerages that charge per trade.

Starting small and building over time

You do not need $10,000 to start. Many brokerages let you open an account with $1 or $100. Set up automatic monthly contributions — even $50 per month adds up. This approach, called dollar-cost averaging, means you buy more shares when prices are low and fewer when prices are high. You avoid the mistake of investing a lump sum right before a market crash.

A 25-year-old who invests $100 per month for 40 years at 8% annual returns ends up with roughly $301,000. A 35-year-old who waits 10 years, then invests $200 per month for 30 years at the same 8% return ends up with roughly $233,000. Starting 10 years earlier, even with half the monthly amount, builds $68,000 more. Time compounds your money faster than the size of each contribution.

Automate your contributions so you do not have to think about it. Set the amount to something you will not miss — even if it is $25 per month. Increase it whenever you get a raise. Most brokerages let you set this up in minutes.

What to do when the market drops

Markets fall roughly every 3 to 5 years. A 10% drop is normal. A 20% drop happens every 5 to 10 years. When this happens, your account balance shrinks. This is the moment most people panic and sell, locking in losses. This is also the moment you should keep investing — you are buying stocks at lower prices.

If you are investing for retirement and will not touch the money for 20 years, a market drop is good news. You are buying shares at a discount. If you need the money in 2 years, you should not have it in stocks at all — keep it in a high-yield savings account or short-term CDs instead.

The rule is simple: invest only money you will not need for at least 5 years, preferably 10 or more. If you cannot follow this rule, stocks are not the right place for that money.

Frequently Asked Questions

Do I need to pick individual stocks to make real money?

No. Index funds have made millionaires out of ordinary people who never picked a single stock. Warren Buffett, one of the world's best investors, recommends that most people buy index funds instead of individual stocks. You make real money through consistent investing over decades, not through picking winners.

What is the difference between a stock and a mutual fund?

A stock is ownership in one company. A mutual fund or ETF is a basket of stocks (or bonds, or both) bundled together. When you buy a mutual fund, you own a tiny piece of every stock in that basket. Funds reduce risk because one bad company does not sink your whole investment.

Can I lose more money than I invested?

No, not with stocks or funds. The worst that can happen is your investment goes to zero. You cannot owe money to the brokerage. (This is different from buying on margin or using options, which are advanced strategies you should avoid until you have years of experience.)

How much should I have in stocks versus bonds or savings?

A common rule is: subtract your age from 110, and that is the percentage to keep in stocks. A 30-year-old would hold 80% stocks and 20% bonds or savings. A 60-year-old would hold 50% stocks and 50% bonds or savings. Adjust based on how much risk you can stomach — if a 20% market drop would make you sell in panic, hold more bonds and savings.

Is now a good time to start investing?

The best time to plant a tree was 20 years ago. The second best time is today. Market timing does not work. People who invested right before the 2008 crash and held on made their money back by 2013. People who waited for the "perfect" time missed the recovery. Start now with money you can leave alone for years.
