Investing in stocks starts with opening a brokerage account, funding it, and buying shares of companies or funds you believe will grow over time. Most major brokerages now charge $0 commissions and have no account minimums, so you can get started with almost any amount of money. The process itself takes less than an hour, but making smart choices along the way will shape your returns for decades.
Pick the Right Account Type
Before you buy a single share, you need to decide where to hold your investments. The two main options are a taxable brokerage account and a retirement account like a Roth IRA. Each treats your money differently when it comes to taxes and access.
A taxable brokerage account lets you buy and sell investments freely with no restrictions on when you can withdraw. The tradeoff is that you owe taxes on dividends, interest, and any profits you make when you sell. There are no contribution limits and no age requirements, which makes this the most flexible option.
A Roth IRA is a retirement account funded with money you’ve already paid taxes on. The big advantage: your investments grow tax-free, and qualified withdrawals in retirement are also tax-free. There are no required minimum distributions, giving you control over when and how much you take out. The downside is that contributions are capped each year and there are income limits that can phase you out of eligibility. If you’re investing for retirement and qualify, a Roth IRA is one of the most tax-efficient places to start.
A Traditional IRA works in the opposite direction. Contributions may be tax-deductible now, reducing your current tax bill, but you’ll pay income tax on withdrawals in retirement. This can make sense if you expect to be in a lower tax bracket later in life.
Many investors open both a retirement account and a taxable brokerage account. The retirement account shelters long-term growth from taxes, while the brokerage account gives you access to money for goals that come before age 59½.
Choose a Brokerage
The major online brokerages have largely eliminated the cost barriers that once kept small investors out. Fidelity, Charles Schwab, Interactive Brokers, Robinhood, and tastytrade all charge $0 for stock trades and require no minimum deposit to open an account. All of them also offer fractional shares, meaning you can buy a slice of an expensive stock for as little as $1 or $5 instead of paying full price for one share.
When choosing a platform, look beyond commissions. Consider the quality of the mobile app and website, the range of educational resources, customer support availability, and whether the platform offers the account types you want (Roth IRA, taxable, etc.). If you plan to buy mutual funds, check whether the broker offers a large selection with no transaction fees. Some brokerages, like E*TRADE, only offer fractional shares through a robo-advisor portfolio or dividend reinvestment, so if buying partial shares matters to you, confirm that feature before signing up.
Decide What to Invest In
This is where most beginners stall. The stock market offers thousands of individual companies and funds, and the sheer number of choices can feel paralyzing. A useful framework is to start broad and get more specific as your knowledge grows.
Index Funds and ETFs
For most beginners, index funds are the simplest and most effective starting point. An index fund tracks a market benchmark, like the S&P 500 (which holds the 500 largest U.S. companies), and gives you exposure to hundreds or thousands of securities in a single purchase. That instant diversification means your portfolio isn’t tied to the fate of any one company.
Index funds come in two forms: mutual funds and exchange-traded funds (ETFs). Both follow the same passive strategy of mirroring an index, but they differ in how you buy them. ETFs trade on the stock exchange throughout the day, just like individual stocks, with prices that fluctuate in real time. Index mutual funds are priced once at the end of each trading day, and you buy shares directly from the fund company. ETFs generally have lower expense ratios (the annual fee expressed as a percentage of your investment) and are more tax-efficient. Mutual fund versions may be available commission-free through certain brokers and offer the simplicity of predictable end-of-day pricing.
A single S&P 500 index fund with an expense ratio under 0.10% is a common first investment. You’ll pay less than $1 per year in fees for every $1,000 invested, and you’ll own a piece of the broad U.S. economy.
Individual Stocks
Buying shares of a single company gives you direct ownership in that business. If the company grows and earns more profit, the stock price generally rises, and many companies also pay dividends (cash payments to shareholders). The risk is concentration: if that one company stumbles, your investment can drop significantly. Most financial professionals suggest limiting individual stocks to a portion of your portfolio rather than making them the entire thing, especially while you’re learning.
Understand Order Types
When you’re ready to buy, your brokerage will ask what type of order you want to place. The two you’ll use most often are market orders and limit orders.
A market order tells your broker to buy or sell immediately at the best available price. It guarantees your trade will go through but not the exact price you’ll pay. For large, heavily traded stocks, the price you see on screen and the price you get are usually very close. For smaller or more volatile stocks, the gap can be wider.
A limit order lets you set the maximum price you’re willing to pay (when buying) or the minimum you’re willing to accept (when selling). If the stock never hits your price, the trade doesn’t execute. For example, if a stock is trading at $12 but you only want to pay $10, a buy limit order will sit and wait until the price drops to $10 or lower. This gives you more control, especially when prices are moving quickly.
A stop order (sometimes called a stop-loss) triggers a sale when a stock falls to a certain price. If you bought a stock at $50 and set a stop order at $45, your shares would automatically be sold if the price dropped to $45, limiting your loss. Once triggered, the stop order becomes a market order, so the final sale price could be slightly above or below $45.
For most routine purchases of well-known stocks or ETFs during market hours, a market order works fine. Use limit orders when you want to control your entry price or when trading less liquid investments.
Build a Strategy You Can Stick With
Investing successfully has less to do with picking the perfect stock and more to do with consistency. One of the most effective approaches for beginners is dollar-cost averaging: investing a fixed amount on a regular schedule, whether that’s $50 every week or $500 every month. When prices are high, your fixed amount buys fewer shares. When prices are low, it buys more. Over time, this smooths out the ups and downs and removes the pressure of trying to time the market.
Most brokerages let you set up automatic recurring investments, so the money moves from your bank account into your chosen fund without you having to remember. This turns investing from an occasional decision into a habit.
Diversification also matters. Owning a mix of U.S. stocks, international stocks, and bonds reduces the chance that a single bad year in one area wipes out your progress. A simple three-fund approach (a U.S. stock index fund, an international stock index fund, and a bond index fund) covers most of the global market and can be adjusted as your goals and timeline change.
Know How Taxes Work
In a taxable brokerage account, you’ll owe taxes on two things: dividends you receive and profits you make when you sell. How much you owe depends on how long you held the investment.
If you sell a stock or fund you’ve held for more than one year, the profit is taxed at the long-term capital gains rate, which is lower than ordinary income tax rates for most people. For 2026, single filers pay 0% on long-term gains if their taxable income is under $49,450, 15% on gains above that threshold up to $545,500, and 20% above $545,500. Married couples filing jointly hit the 15% rate at $98,900 and the 20% rate at $613,700.
If you sell an investment you’ve held for one year or less, the profit counts as a short-term capital gain and is taxed at your regular income tax rate, which is typically higher. This is one reason buy-and-hold investing tends to be more tax-efficient than frequent trading.
Inside a Roth IRA, none of this matters day to day. Your investments grow without triggering any tax, and qualified withdrawals are tax-free. Inside a Traditional IRA, gains aren’t taxed until you withdraw, at which point you pay ordinary income tax. Choosing the right account type can save you thousands of dollars over a long investing career.
How Much Money You Need to Start
With $0 account minimums and fractional shares widely available, you can start investing with as little as $1. The more important question is how much you can invest consistently. Even small amounts compound over time. Investing $100 per month into an S&P 500 index fund averaging a 10% annual return (the long-term historical average, before inflation) would grow to roughly $76,000 in 20 years, with only $24,000 of that being money you actually contributed. The rest is investment growth.
Start with whatever amount doesn’t strain your budget, and increase it as your income grows. The biggest advantage a beginner has is time.
