You need a brokerage account, money to invest, and a way to pick stocks or funds

Getting into stocks means opening an account with a brokerage firm, depositing money, and then buying shares or stock funds. You do not need a lot of money to start — many brokerages let you open an account with $0 and buy fractional shares (pieces of a stock) for as little as $1. The hardest part is not the mechanics; it is deciding what to buy and sticking with it when prices drop.

The process itself takes about 15 minutes. You pick a brokerage, fill out an online form with your name and Social Security number, link a bank account, and transfer money. Within a day or two, you can place your first trade. What takes longer is understanding what you are buying and why.

Key Takeaways

  • A brokerage account is where you hold stocks and funds; popular low-cost options include Fidelity, Vanguard, Charles Schwab, and Robinhood, each with different minimums and features.
  • You can start with as little as $1 by buying fractional shares, though most people benefit from investing at least $100 to $500 to make the account worth managing.
  • Index funds and target-date funds are simpler for beginners than picking individual stocks because they spread your money across many companies automatically.
  • Your first decision is whether to invest in a regular taxable account or a retirement account like an IRA, which has tax advantages but locks money away until age 59½.

Choosing a brokerage and opening an account

A brokerage is a company that lets you buy and sell stocks. The major ones used by beginners are Fidelity, Vanguard, Charles Schwab, and Robinhood. Each charges different fees and has different rules about minimum deposits and account types.

Fidelity, Vanguard, and Schwab all allow you to open an account with no minimum deposit. Robinhood also has no minimum. The difference is in what they charge per trade and what educational resources they offer. Fidelity and Schwab offer free research tools and educational articles. Vanguard is known for low-cost index funds. Robinhood appeals to people who want a straightforward mobile app and no account fees.

To open an account, go to the brokerage's website, click "Open an Account," and fill in your name, address, date of birth, and Social Security number. The brokerage will ask whether you want a regular taxable account or a retirement account (IRA). If you are unsure, start with a regular account — you can always open an IRA later. After you submit the form, the brokerage will verify your identity, usually within minutes. You can then link your bank account and transfer money.

Deciding between a regular account and a retirement account

A regular taxable account has no rules about when you can withdraw money or how much you can put in. You pay taxes on any gains when you sell. An IRA (Individual Retirement Account) lets your money grow without paying taxes on gains each year, but you cannot withdraw it before age 59½ without a penalty, and you can only put in $7,000 per year (as of 2024, though this amount changes).

For most beginners, a regular account makes sense if you might need the money within the next five years or if you are not sure how much you will invest. An IRA makes sense if you are saving specifically for retirement and want the tax break. You do not have to choose one or the other forever — you can have both.

If you do open an IRA, you will see two types: a Traditional IRA and a Roth IRA. A Traditional IRA lets you deduct your contributions from your taxes now, but you pay taxes when you withdraw in retirement. A Roth IRA takes after-tax money now, but withdrawals in retirement are tax-free. For a beginner with a lower income, a Roth often makes more sense, but this depends on your situation.

Starting with index funds or target-date funds instead of individual stocks

Once your account is open and funded, you face the question: what do you buy? The simplest answer for a beginner is an index fund or target-date fund, not individual stocks.

An index fund is a collection of stocks bundled together to track a market index — for example, the S&P 500 index fund holds shares in 500 large U.S. companies. When you buy one share of an S&P 500 index fund, you own a tiny piece of all 500 companies. This spreads your risk: if one company fails, it barely dents your investment. Index funds charge very low fees (often 0.03% to 0.20% per year) and historically return about 10% per year on average over long periods, though some years are much higher and some are much lower.

A target-date fund is even simpler. You pick the year you plan to retire, and the fund automatically adjusts its mix of stocks and bonds as you get closer. A 2055 target-date fund, for example, holds mostly stocks now and will gradually shift toward bonds as 2055 approaches. You buy one fund and do not have to think about rebalancing.

Individual stocks are riskier and require more research. If you want to try picking stocks later, start by reading the company's annual report (called a 10-K) and understanding its business. But for your first investment, an index fund or target-date fund removes the guesswork.

How much money to start with and where it comes from

You can technically start with $1, but that is not practical because you will spend more in taxes and time managing the account than you earn. Most people benefit from starting with at least $100 to $500. If you have $1,000 or more, even better — the compounding effect (earning returns on your returns) becomes more visible.

The money should come from savings you do not need for emergencies or bills in the next few years. If you do not have an emergency fund of three to six months of expenses, build that first in a high-yield savings account. Then invest the money you can afford to leave alone for at least five years.

If you do not have a lump sum, you can start with whatever you have and add more over time. Many people set up automatic transfers from their checking account to their brokerage account — $50 or $100 per month, for example. This is called dollar-cost averaging, and it removes the pressure of trying to time the market perfectly.

Understanding fees and keeping costs low

Brokerages make money in several ways, and understanding these costs matters because they eat into your returns. The main ones are trading commissions, account fees, and fund expense ratios.

Most major brokerages (Fidelity, Vanguard, Schwab, Robinhood) charge zero commission to buy or sell stocks and funds. This was not always true — 20 years ago, a single trade cost $5 to $10. Today it is free, which is a huge advantage for beginners.

Account fees are annual charges just for having an account. Most brokerages waive these if you maintain a minimum balance (often $0 or $2,500). Check the fine print when you open your account.

The biggest ongoing cost is the expense ratio of the fund you buy. This is the annual percentage the fund charges to manage your money. A good index fund charges 0.03% to 0.20% per year. An actively managed fund (where a manager picks stocks) often charges 0.5% to 1.5% or more. Over 30 years, that difference compounds dramatically. A $10,000 investment in a 0.05% fund grows to roughly $80,000, while the same money in a 1% fund grows to roughly $65,000 — a $15,000 difference from fees alone.

Making your first purchase

Once money is in your account, buying is straightforward. Log into your brokerage, search for the fund or stock you want, and click "Buy." You will see a screen asking how many shares you want and at what price. For a beginner, use a "market order," which buys at the current price when ready. (Advanced traders use "limit orders" to buy only if the price drops to a certain level, but this is not necessary to start.)

After you click "Confirm," the trade executes within seconds during market hours (9:30 a.m. to 4 p.m. Eastern Time on weekdays). You will see the shares appear in your account, and you own them. That is it. You do not have to do anything else unless you want to buy more or sell.

Many beginners feel pressure to check their account constantly and trade frequently. Resist this. The best investors buy and hold for years. Checking daily or trading weekly usually costs you money in taxes and fees and rarely improves results.

Frequently Asked Questions

Do I need a lot of money to start investing in stocks?

No. Most brokerages let you open an account with $0 and buy fractional shares for $1 or more. However, starting with at least $100 to $500 makes the account worth managing. If you have less, focus on building an emergency fund first, then invest what you can afford to leave alone for several years.

What is the difference between a stock and a fund?

A stock is a share of one company. A fund is a basket of many stocks (or bonds) bundled together. When you buy a fund, you own a tiny piece of every holding in it. Funds spread risk across many companies, while a single stock is riskier but can grow faster if that company succeeds.

Should I pick individual stocks or buy index funds?

For a beginner, index funds or target-date funds are simpler and historically outperform most people who pick individual stocks. If you want to learn about picking stocks later, start by reading company financial reports and understanding the business. But your first investment should probably be a low-cost index fund.

Can I lose all my money in the stock market?

If you buy a diversified index fund, losing everything is extremely unlikely — it would require the entire U.S. economy to collapse. Individual stocks can go to zero, which is why beginners should avoid them. Even in the worst market crashes (2008, 2020), the S&P 500 recovered within a few years. Time in the market beats timing the market.

When should I sell my stocks?

For a long-term investor, the answer is usually "not yet." Selling triggers taxes and locks in losses. Most people benefit from buying and holding for at least five to ten years. Sell only if you need the money, your life circumstances change, or your investment thesis (the reason you bought it) no longer holds.
