Where to open an investment account and what type to choose
You invest money by opening an account at a brokerage firm, then buying investments through that account. The brokerage holds your money and executes your trades. The most common brokerages for individual investors are Fidelity, Vanguard, Charles Schwab, E-Trade, and Robinhood, though many others exist. Each charges different fees and offers different tools, so the one you pick matters to your costs over time.
Before you pick a brokerage, decide what type of account you want. A taxable brokerage account has no contribution limits and no withdrawal restrictions—you can put in as much as you want and take money out whenever you need it. You pay taxes on gains and dividends each year. A retirement account like a 401(k) or IRA has contribution limits (the IRS sets these annually and they change year to year) but offers tax advantages: either you don't pay taxes on the money going in, or you don't pay taxes on the growth, depending on the account type. Retirement accounts penalize you for withdrawing before age 59½, with rare exceptions.
If your employer offers a 401(k) and matches contributions, start there—the match is assistance programs. If not, or if you want to invest beyond the 401(k) limit, open an IRA at a brokerage. If you have money left after maxing retirement accounts and want to invest more, use a taxable account.
Key Takeaways
- You invest by opening an account at a brokerage like Fidelity or Vanguard, then buying stocks, bonds, or funds through that account.
- Retirement accounts (401(k), IRA) have contribution limits and tax advantages but penalize early withdrawal; taxable accounts have no limits but you pay taxes on gains each year.
- If your employer matches 401(k) contributions, contribute enough to get the full match before opening other accounts.
- Most beginner investors start with low-cost index funds or target-date funds rather than picking individual stocks.
- You need an initial deposit to open an account, which ranges from zero to several thousand dollars depending on the brokerage and account type.
What you actually buy: stocks, bonds, and funds
Once your account is open, you choose what to buy. A stock is a small piece of ownership in a company. A bond is a loan you make to a company or government; they pay you interest. A fund is a collection of many stocks or bonds bundled together, so one purchase gives you pieces of dozens or hundreds of companies.
Most people starting out buy funds rather than individual stocks, because funds spread your money across many investments and reduce the damage if one company fails. An index fund tracks a specific group of companies—the S&P 500 index fund, for example, holds pieces of 500 large U.S. companies in the same proportions as the index itself. A target-date fund automatically shifts from stocks to bonds as you get closer to retirement, so you don't have to rebalance manually.
Funds charge fees called expense ratios, stated as a percentage of your money per year. A 0.03% expense ratio on a $10,000 investment costs you $3 per year. A 1% ratio costs $100 per year. Over decades, the difference compounds—low-cost index funds (typically 0.03% to 0.20%) beat high-cost funds (1% or more) for most investors, even before accounting for taxes.
How much money you need to start
The minimum deposit to open an account varies. Many brokerages like Fidelity and Charles Schwab have no account minimum—you can open with $1. Some require $500, $1,000, or more. Some index funds have minimums of $1,000 or $3,000, though many now have no minimum. Check the specific brokerage and fund before you open.
You do not need a large sum to begin. Starting with $500 or $1,000 and adding money regularly over time builds wealth faster than waiting for a large lump sum. Many investors set up automatic transfers—$100 or $200 per paycheck—into their investment account. This is called dollar-cost averaging, and it removes the guesswork of timing the market.
The actual steps to make your first purchase
Open an account on the brokerage website or app. You will need your Social Security number, address, employment information, and bank account details. The process takes 10 to 20 minutes. The brokerage will verify your identity and may ask for a photo of your ID.
Link your bank account and transfer money into the brokerage account. This usually takes one to three business days to clear. Once the money is in your brokerage account, you are ready to buy.
Search for the fund or stock you want to buy by its ticker symbol (a short code like "VOO" for Vanguard's S&P 500 index fund). Enter the dollar amount or number of shares you want to purchase. Review the order and confirm. The purchase executes immediately during market hours (9:30 a.m. to 4 p.m. Eastern time on weekdays when the market is open). You now own that investment.
Why fees and costs matter more than you think
Every dollar you pay in fees is a dollar that does not grow. A fund charging 1% per year instead of 0.10% costs you roughly $9,000 more on a $100,000 investment over 30 years, assuming 7% annual returns. That gap widens with larger amounts and longer time horizons.
Beyond expense ratios, watch for trading commissions (fees per trade), account maintenance fees, and advisory fees. Most major brokerages have eliminated per-trade commissions for stocks and funds, but some still charge them. Always check the fee schedule before you open an account.
Tax-loss harvesting and account placement (putting tax-inefficient investments in retirement accounts and tax-efficient ones in taxable accounts) also reduce what you owe. These are advanced moves, but they matter once you have money across multiple accounts.
How to decide between doing it yourself and paying someone
You can manage your own investments by picking funds and rebalancing once or twice a year. This costs almost nothing beyond the fund's expense ratio. Many people do this successfully with a simple plan: pick a target-date fund matching your retirement year, set up automatic monthly deposits, and check it once a year.
You can also pay a robo-advisor like Betterment or Wealthfront to manage your account automatically. They charge 0.25% to 0.50% per year and handle rebalancing for you. This costs more than doing it yourself but less than hiring a human advisor.
A human financial advisor typically charges 0.50% to 1.50% per year or a flat fee. They provide personalized advice and may help with tax strategy, insurance, and estate planning. This makes sense if your situation is complex (multiple income sources, inheritance, business ownership) or if you strongly prefer not to make investment decisions yourself.
What happens after you buy: monitoring and rebalancing
After you purchase, your investment grows or shrinks based on market performance. You do not need to check it daily—in fact, frequent checking often leads to panic selling during downturns. Most investors check quarterly or annually.
Rebalancing means adjusting your holdings back to your target mix. If you wanted 70% stocks and 30% bonds, but stocks rose to 75% of your portfolio, you would sell some stocks and buy bonds to return to 70/30. This forces you to sell high and buy low, which improves long-term returns. Rebalance once or twice a year, or when your allocation drifts more than 5% from your target.
If you are using a target-date fund or robo-advisor, rebalancing happens automatically. If you are picking individual funds, you do it manually or set up automatic rebalancing through your brokerage.
Common mistakes to avoid when you start investing
Trying to time the market—selling before a crash or buying before a rally—almost never works. Even professional investors fail at this. Instead, invest regularly regardless of market conditions and stay invested through downturns.
Chasing performance by buying funds that did well last year often backfires. Last year's winner is frequently this year's loser. Stick to a simple, diversified plan and ignore the noise.
Paying high fees without realizing it. Read the expense ratio and fee schedule before you buy. A 1% fee sounds small until you realize it costs you tens of thousands over decades.
Investing money you will need within five years. The stock market can drop 20%, 30%, or more in a single year. If you need the money soon, keep it in a savings account or short-term bonds instead.
Frequently Asked Questions
Do I need a lot of money to start investing?
No. Many brokerages have no minimum deposit, and you can start with $100 or $500. Regular small deposits over time build wealth faster than waiting for a large sum. The key is starting early so your money has time to grow.
What is the difference between a 401(k) and an IRA?
A 401(k) is offered by your employer and often includes a matching contribution. An IRA is opened on your own at a brokerage. 401(k)s have higher contribution limits but fewer investment choices. IRAs have lower limits but more flexibility. If your employer offers a match, prioritize the 401(k) first.
Should I pick individual stocks or funds?
Most people do better with funds, especially when starting out. Funds spread your money across many companies, reducing risk. Individual stocks require more research and time. If you enjoy research and have money to spare, picking a few stocks is fine—just keep most of your money in diversified funds.
How often should I check my investments?
Checking quarterly or annually is enough. Checking daily or weekly often leads to emotional decisions during market swings. Set a calendar reminder to review once a year, rebalance if needed, and then step back.
What if the market crashes after I invest?
Market crashes are normal and temporary. If you sell during a crash, you lock in losses. If you hold and keep investing, you buy more shares at lower prices, which accelerates recovery. History shows that investors who stayed invested through crashes came out ahead.
