One fact makes investing far less scary: you don't buy investments out of thin air. You open an account, put money in it, and use that account to buy what you want. Picking the right type of account is most of the decision.

The account is the container

An investing account is a basket that holds your investments. The money you add can sit as cash until you use it to buy a or a fund. Different baskets come with different rules and tax perks, so it's worth knowing the main three.

The three accounts worth knowing

  • 401(k): a retirement account offered through a job. Money often comes straight out of your paycheck before taxes, and many employers add free matching money on top.
  • Roth IRA: a retirement account you open yourself. You put in money you've already paid tax on, and qualified withdrawals later in life come out tax-free.
  • Brokerage account: a flexible account with no special tax perks and no rules about when you can take money out. Good for goals beyond retirement.

Retirement accounts let you add money only up to a yearly limit: for 2026, that's $7,500 for an or , and $24,500 for a through work. (Both rise a bit most years.) A regular has no such cap. If you want a fuller tour of the retirement options, Retirement & Tax-Advantaged Accounts, Explained maps them out.

If your job offers to match part of your 401(k), contribute at least enough to get the full match. It's part of your pay you'd otherwise leave behind, and the closest thing to free money you'll find.

How to actually open one

  1. 1Pick where it lives. For a 401(k), ask your employer. For a Roth IRA or brokerage account, choose a reputable online brokerage.
  2. 2Sign up online. You'll enter your name, address, , and bank details; it usually takes about 15 minutes.
  3. 3Link your bank and move in your first deposit, even if it's small.
  4. 4Choose an investment to buy with that cash. Many beginners start with a single broad .
Tip
Your money isn't invested just because it's in the account. Cash sitting there does nothing until you use it to buy something. Don't forget that last step.

Starting small is smart. Open the account, get one dollar invested, and you've already done the part most people put off for years. You can always add more once it feels familiar.
