The main places people invest are brokerage accounts, retirement accounts, and robo-advisors
Where you invest depends on what you are saving for and how much control you want over your choices. A brokerage account is a regular investment account you open with a bank or investment firm — you can buy and sell stocks, bonds, and funds whenever you want, and withdraw money anytime without penalty. A retirement account like a 401(k) or IRA has tax advantages but locks your money away until age 59½; you choose this route if you are saving for retirement specifically. A robo-advisor is a service that builds and manages a portfolio for you automatically based on your age and risk tolerance — you hand over the decisions and pay a small fee.
Each route has different costs, different rules about when you can take money out, and different tax treatment. The right choice depends on whether you are saving for retirement, a house down payment, or something else; how much money you have to start; and whether you want to pick individual stocks or let someone else manage it.
Key Takeaways
- Brokerage accounts have no contribution limits and no withdrawal penalties, but you pay taxes on gains every year.
- Retirement accounts like 401(k)s and IRAs reduce your taxable income now, but you cannot withdraw before 59½ without a 10 percent penalty plus taxes.
- Robo-advisors charge 0.25 to 0.50 percent per year and handle buying and selling for you, making them simpler than picking stocks yourself.
- If your employer offers a 401(k) match, contributing enough to get the full match is usually the first step before opening other accounts.
- The platform you choose — Fidelity, Vanguard, Charles Schwab, Betterment, or others — matters less than the account type and the fees you pay.
Brokerage accounts: no restrictions, but you pay taxes yearly
A brokerage account is the most flexible option. You open one with a bank or investment firm, deposit money, and buy whatever you want — individual stocks, exchange-traded funds (ETFs), mutual funds, bonds. You can sell anytime and withdraw the cash to your bank account in a few business days. There is no limit on how much you can deposit or how much you can withdraw.
The trade-off is taxes. Every time you sell a stock or fund at a profit, you owe capital gains tax. If you hold it less than a year, you pay short-term capital gains tax at your regular income tax rate. If you hold it a year or longer, you pay the lower long-term rate. You also owe tax on any dividends the fund or stock pays, even if you do not sell. This means a brokerage account works best for money you do not need for at least a few years, so you can hold investments long enough to may have access to for the lower long-term rate.
Most major banks and investment firms offer brokerage accounts with no account fees. You pay commissions only when you buy or sell, and many firms now charge zero commission on stocks and ETFs. The main cost is the expense ratio of the funds you buy — typically 0.03 to 0.20 percent per year for index funds, higher for actively managed funds.
Retirement accounts: tax breaks now, but money is locked until 59½
A 401(k) is a retirement account your employer offers. You contribute money from your paycheck before taxes are taken out, which lowers your taxable income for the year. Your employer may match part of what you contribute — for example, matching 50 cents for every dollar you put in, up to 3 percent of your salary. That match is assistance programs. You choose how to invest the money from a menu of funds the plan offers, and you pay no taxes on gains until you withdraw in retirement.
The catch is that you cannot touch the money until age 59½ without paying a 10 percent penalty plus income tax on the withdrawal. There are narrow exceptions — hardship withdrawals for medical bills or eviction, loans against your balance — but they are difficult to use. If you leave your job, you can roll the 401(k) into an IRA to keep it invested, or leave it with your former employer's plan if the balance is large enough.
An IRA (Individual Retirement Account) is a retirement account you open on your own, not through an employer. A traditional IRA works like a 401(k): you deduct contributions from your taxes, and you pay taxes on withdrawals in retirement. A Roth IRA is different — you contribute after-tax money, so you get no deduction now, but withdrawals in retirement are tax-free. Roth IRAs also let you withdraw contributions (not earnings) anytime without penalty, making them slightly more flexible. For 2024, you can contribute up to $7,000 per year to an IRA if you are under 50, or $8,000 if you are 50 or older. Income limits apply to Roth IRAs; traditional IRAs have no income limit, but the deduction phases out if you have a 401(k) at work.
If your employer does not offer a 401(k), or if you are self-employed, you can open a SEP IRA or Solo 401(k), which allow higher contribution limits. A SEP IRA lets you contribute up to 25 percent of your net self-employment income, up to $69,000 per year in 2024. These accounts work the same way as traditional IRAs — contributions are tax-deductible, and withdrawals in retirement are taxed as income.
Robo-advisors: automated investing with lower fees
A robo-advisor is a service that builds and manages a portfolio for you. You answer questions about your age, income, risk tolerance, and time horizon. The algorithm then creates a mix of index funds — usually a combination of stock and bond funds — and rebalances it automatically as markets move. Examples include Betterment, Wealthfront, and Vanguard Personal Advisor Services.
The main advantage is simplicity. You do not have to decide which individual stocks or funds to buy; the robo-advisor does it for you. The main cost is the annual fee, typically 0.25 to 0.50 percent of your account balance. Some robo-advisors charge nothing if your balance is below a certain amount, or charge a flat monthly fee instead. You can open a robo-advisor brokerage account or a robo-advisor IRA, depending on your goal.
Robo-advisors work well if you have $500 to $5,000 to start and want a hands-off approach. If you have less than $500, many charge no fee or a flat fee that makes more sense. If you have more than $100,000 and want personalized advice, a human financial advisor or a robo-advisor with a human option may be worth the higher cost.
How to choose between account types
Start by asking what you are saving for. If it is retirement and you have access to a 401(k) at work, contribute enough to get the full employer match — that is an immediate return on your money. If you do not have a 401(k), open a Roth IRA if your income qualifies, or a traditional IRA if it does not. Max out the IRA contribution ($7,000 or $8,000 per year) before opening a brokerage account.
If you are saving for something other than retirement — a house down payment, a car, a vacation in five years — use a brokerage account. You will pay taxes on gains, but you can access the money whenever you need it without penalty. If you are saving for retirement and have already maxed out your 401(k) and IRA, open a brokerage account and invest the rest there; it will be taxed annually, but it is better than leaving money in a savings account earning nothing.
If you do not want to pick individual investments, use a robo-advisor. If you want full control and are willing to research funds and stocks yourself, use a brokerage account. If you want a mix — mostly automated, but the option to buy individual stocks — open a brokerage account and use it like a robo-advisor by buying a few low-cost index funds and leaving them alone.

The platform you choose matters less than the account type and the fees. All of these firms are regulated by the SEC and FINRA, so your money is protected. Fidelity, Vanguard, and Charles Schwab all offer the same low-cost index funds. The differences are in user interface, customer service, and whether they offer robo-advisor services. Open an account with whichever platform feels easiest to you, and you can transfer money to another platform later if you change your mind.
When comparing platforms, look at three things: the expense ratios of the funds they offer, whether they charge account maintenance fees, and what customer support looks like. Most platforms now offer phone, email, and chat support. If you plan to invest small amounts regularly, check whether the platform charges fees for automatic transfers or recurring investments — most do not, but some older platforms still do.
Frequently Asked Questions
Can I have both a 401(k) and an IRA at the same time?
Yes. You can contribute to both in the same year. However, if you have a 401(k) at work, the deduction for a traditional IRA phases out at higher incomes. A Roth IRA has no income limit if you do not have a 401(k), but has income limits if you do. Check the IRS limits for your income level before opening a traditional IRA.
What is the difference between an ETF and a mutual fund?
Both are baskets of stocks or bonds. A mutual fund is priced once per day after the market closes; an ETF trades throughout the day like a stock. ETFs usually have lower expense ratios and are more tax-efficient. For most beginners, the difference does not matter — pick whichever has the lower fee.
Do I need a lot of money to start investing?
No. Most brokerages let you open an account with $0 and buy fractional shares, so you can invest $50 or $100 at a time. Robo-advisors often have no minimum either, though some charge a monthly fee if your balance is small. Start with whatever you can afford and add to it over time.
What happens to my investments if the brokerage goes out of business?
Your investments are protected. Brokerages are required to hold your securities in your name, separate from the firm's own assets. If the firm fails, your stocks and funds transfer to another brokerage. Cash in your account is insured up to $250,000 by the SIPC (Securities Investor Protection Corporation).
Should I invest in individual stocks or index funds?
Most people do better with index funds. Individual stocks require research and time; most active traders underperform the market after fees and taxes. Index funds track the whole market or a sector, charge low fees, and require no ongoing decisions. Start with index funds and move to individual stocks only if you enjoy research and have money you can afford to lose.
