How to Start Investing: A Step-by-Step Guide for Beginners

Step 1: set a goal and a time horizon

Money you need within a few years does not belong in stocks, which can fall 30% or more in a bad year. Investing suits goals that are five or more years away: retirement, a home deposit in a decade, a child's education. Write the goal and the date. They decide how much risk makes sense.

Step 2: build a safety net first

• An emergency fund of three to six months of essential expenses in a savings account, so a bad month does not force you to sell investments at a loss. See how to save money.
• High-interest debt (such as credit cards) usually costs more than a stock portfolio is likely to earn. Paying it off is a guaranteed return.

Step 3: choose the account

• Employer plan (401(k)): contributions often come before tax, and many employers add a match, which is extra money.
• IRA or Roth IRA: accounts with tax advantages for retirement, with annual limits set by the IRS.
• Taxable brokerage account: no contribution limit and no restriction on withdrawals, but gains and dividends are taxed each year.

Limits and rules change every year. Check the IRS or ask a tax professional.

Step 4: pick a regulated broker

Use a broker registered in the US and check it in FINRA BrokerCheck. Customer assets are protected by SIPC up to $500,000 (including $250,000 for cash) if the broker fails, according to SIPC; this does not protect against market losses. Compare fees, available investments, fractional shares and tools. Avoid anyone who promises returns, pressures you to deposit quickly, or contacts you first on social media.

Step 5: decide what to buy

• Broad index funds or ETFs give diversification in one step. See ETFs vs stocks.
• Individual stocks require research. Learn to judge whether a stock is cheap and to read earnings.
• Many people mix both with a core and a smaller satellite.

Step 6: start with an amount you can keep up

The best amount is the one you can invest every month for years. You do not need a lot: see how much money you need to start. Investing a fixed sum on a regular date (dollar-cost averaging) removes the need to guess the right day. Use the compound interest calculator to see what regular contributions can do over time, with illustrative rates.

Step 7: practise and review

Check your portfolio once or twice a year, not every day. Keep a note of why you bought each company. If you want to practise first, ATLAS lets you build and test a portfolio before using real money (see the portfolio builder).

Common mistakes to avoid

• Investing money you will need soon.
• Chasing what rose last month.
• Putting everything in one stock.
• Selling in a panic after a fall.
• Paying high fees without noticing them.
• Following tips from strangers online. Check the SEC's investor alerts before trusting an offer.
