Start with a brokerage account and buy individual stocks, funds, or bonds

To invest money, you open an account with a brokerage firm, deposit cash, and then buy investments through that account. The brokerage holds your money and executes your trades. You can start with as little as $1 to $100 depending on the brokerage and what you want to buy. The whole process takes about 15 minutes online.

Most people do not pick individual stocks. Instead, they buy mutual funds or exchange-traded funds (ETFs)—baskets of many stocks or bonds bundled together. This spreads your risk across dozens or hundreds of companies instead of betting on one. A fund might cost $50 to $500 per share, and you can own a fraction of a share with many brokerages.

The three main account types are taxable brokerage accounts (no contribution limits, you pay tax on gains each year), 401(k) accounts (through your employer, contributions reduce your taxable income), and IRAs (individual retirement accounts, with annual contribution limits and tax advantages). Most people start with a taxable account if they do not have a 401(k), or max out their 401(k) first if their employer matches contributions.

Key Takeaways

  • Open a brokerage account online with a firm like Fidelity, Vanguard, or Charles Schwab, deposit money, and buy funds or individual stocks through the account.
  • Most new investors buy mutual funds or ETFs rather than individual stocks, because funds spread risk across many companies and require less research.
  • A 401(k) through your employer usually comes first because employer matching is assistance programs, followed by maxing an IRA, then a taxable brokerage account.
  • Your investment mix should match your time horizon and risk tolerance—stocks for 10+ years, bonds for shorter timelines, and a mix of both for most people.
  • Costs matter: look for low expense ratios (under 0.20% for index funds) and avoid accounts with monthly fees or high trading commissions.

Choose a brokerage and open an account in 15 minutes

A brokerage is a company that lets you buy and sell investments. The major ones are Fidelity, Vanguard, Charles Schwab, E*TRADE, and Webull. All of them offer free stock and ETF trading with no account minimums. You pick one, go to their website, and fill out a form with your name, address, Social Security number, and employment information.

After you submit the form, the brokerage verifies your identity (usually instant) and opens your account. You then link a bank account and transfer money in. The transfer takes one to three business days. Once the cash lands in your brokerage account, you can buy investments immediately.

Do not worry about picking the "best" brokerage. The differences between Fidelity, Vanguard, and Schwab are small for a beginner. All three have low fees, good customer service, and thousands of funds to choose from. Pick whichever has the clearest website or the one a friend uses. You can always move your money later if you change your mind.

Decide what to buy: stocks, bonds, or a mix

Once your account is open and funded, you need to decide what to buy. The simplest choice is a target-date fund—a single fund that automatically holds a mix of stocks and bonds, and shifts toward bonds as you get closer to retirement. If you are 30 years old and retiring at 65, you would buy a "2055 target-date fund" or similar. You buy one fund, and it does the rebalancing for you.

If you want more control, you can build your own mix. A common approach for someone with a long time horizon is 80% stocks and 20% bonds. Stocks grow faster over decades but swing up and down in value year to year. Bonds are slower and steadier. The longer you can leave money untouched, the more stocks you can hold.

Within stocks, most people buy a total stock market index fund (which holds nearly every U.S. company) or split between U.S. and international stocks. Within bonds, a total bond market index fund is common. Index funds track a market index and have very low costs—often 0.03% to 0.10% per year. Avoid funds with expense ratios above 0.50% unless you have a specific reason.

Understand the difference between a 401(k), IRA, and taxable account

The account type matters because it determines how much you can contribute each year and how taxes work. A 401(k) is offered by your employer. You contribute pre-tax money (it comes out of your paycheck before taxes), and your employer may match a percentage of what you contribute—often 3% to 6% of your salary. That match is assistance programs. If your employer offers a 401(k) and matches contributions, max out the match first. For 2024, you can contribute up to $23,500 per year.

An IRA (Individual Retirement Account) is an account you open on your own. There are two main types: a traditional IRA (contributions may be tax-deductible, you pay tax when you withdraw in retirement) and a Roth IRA (contributions are after-tax, withdrawals in retirement are tax-free). For 2024, you can contribute $7,000 per year to an IRA if you are under 50. Most people use a Roth IRA if their income is below a certain threshold, because tax-free growth is powerful over decades.

A taxable brokerage account has no contribution limits and no withdrawal restrictions. You pay tax on dividends and capital gains each year. Use this after you have maxed your 401(k) match and your IRA. The order is usually: 401(k) up to the employer match, then max your IRA, then a taxable account.

Know the costs that eat into your returns

Every investment has a cost. The main one is the expense ratio—the annual percentage the fund charges to operate. A fund with a 0.05% expense ratio costs $5 per year for every $10,000 you invest. A fund with 1.00% costs $100 per year on the same $10,000. Over decades, that difference compounds. A 0.05% fund beats a 1.00% fund by tens of thousands of dollars on a $100,000 investment over 30 years.

Look for index funds with expense ratios under 0.20%. Vanguard, Fidelity, and Schwab all offer index funds in the 0.03% to 0.10% range. Avoid actively managed funds (where a manager picks stocks) unless you have a reason—they usually cost 0.50% to 1.50% and rarely beat index funds over long periods.

Other costs to watch: account maintenance fees (most brokerages charge none), trading commissions (all major brokerages offer free stock and ETF trades), and advisory fees if you use a robo-advisor or human advisor. If a brokerage charges a monthly fee, use a different one.

Set up automatic deposits to build the habit

The best investment plan is one you stick to. Set up an automatic transfer from your bank account to your brokerage account every month—$100, $500, $1,000, whatever you can afford. Then set up an automatic purchase of your chosen fund on the same day the money lands. This is called dollar-cost averaging, and it removes emotion from the process. You buy the same fund every month regardless of whether the market is up or down.

Most people underestimate how much small, regular deposits add up. $500 per month for 30 years at 7% average annual returns grows to over $900,000. The key is starting now and staying consistent, not waiting for the "perfect" time to invest or trying to time the market.

Check your account once or twice a year, not every day. Daily checking leads to panic selling when the market drops. Markets drop regularly—that is normal. If you are holding stocks for 10+ years, drops are opportunities to buy more at lower prices, not reasons to sell.

Avoid common beginner mistakes

Do not try to pick individual stocks unless you have time to research companies deeply. Most individual investors underperform index funds. Do not chase hot stocks or cryptocurrencies you read about online. Do not panic and sell when the market drops 10% or 20%—that happens every few years and is not a reason to abandon your plan.

Do not invest money you will need in the next three to five years. Stocks can drop 30% or more in a bad year. If you need the money soon, keep it in a high-yield savings account instead. Do not borrow money to invest. Do not invest in anything you do not understand. If someone is pushing you to invest in something complex or exclusive, walk away.

Do not obsess over beating the market. Your goal is to build wealth over decades by investing consistently and keeping costs low. Most professional investors do not beat the market. You do not need to either.

Frequently Asked Questions

How much money do I need to start investing?

You can start with $1 to $100 depending on the brokerage and what you buy. Most brokerages have no account minimum. You can buy fractional shares of funds and stocks, so you are not locked out by high prices. The real question is not how much you need to start, but whether you can commit to investing regularly over years.

Should I invest in individual stocks or funds?

Most people should buy funds, especially when starting out. A fund spreads your money across dozens or hundreds of companies, so one bad pick does not sink you. Individual stocks require research and carry more risk. If you want to learn about stocks, start by putting 90% in index funds and 10% in individual stocks you understand.

What is the difference between a mutual fund and an ETF?

Both are baskets of stocks or bonds. The main difference is how they trade: mutual funds trade once per day at the end of the day, while ETFs trade throughout the day like stocks. For a beginner, this difference barely matters. Both can have low costs. Pick whichever your brokerage recommends or whichever has a lower expense ratio.

Is it too late to start investing if I am 40 or 50?

No. Even 20 years of investing beats not investing at all. You may need to take more risk (hold more stocks) to catch up, or save more per month, but starting now is always better than waiting. If you are close to retirement, shift toward more bonds and less stocks to reduce the chance of a market drop wiping out your savings right before you need it.

How do I know if my investment is doing well?

Compare it to its benchmark. If you own a total U.S. stock market index fund, compare it to the S&P 500 or total market index. If you own a bond fund, compare it to a bond index. Over one year, your fund might lag or beat the index—that is normal. Over 10+ years, a low-cost index fund should track its benchmark closely. Do not compare your returns to a friend's or to a hot stock you heard about.
