How to Start Investing: The Quick-Start Order

  1. Build a $1,000 starter emergency fund so unexpected expenses don't force you to sell investments early.
  2. Contribute enough to your 401(k) to capture the full employer match (this is an immediate, guaranteed return on your money).
  3. Open a Roth IRA at a major brokerage (Fidelity, Schwab, or Vanguard) and contribute up to the annual limit.
  4. Invest in low-cost index funds — a total US market fund is a solid starting point for most beginners.
  5. Automate contributions so you invest consistently without relying on willpower.

Why Starting Early Is the Biggest Advantage You Have

Starting early matters more than almost any other factor in long-term investing. Compound growth means your investment returns generate their own returns over time. The longer that process runs, the bigger the gap between someone who started at 22 and someone who started at 32. A few years of head start in your 20s can be worth more than decades of contributions started later.

Investing $50 a month imperfectly beats waiting until you feel "ready" and never starting. The math strongly favors getting in sooner, even with small amounts.

Step 1: Build a Small Emergency Fund First

Before you invest anything beyond your employer's 401(k) match, make sure you have at least one month of essential expenses saved as a cash buffer. Investing without an emergency fund means you risk having to sell investments at a bad time when an unexpected expense hits. Even a small cushion changes the math significantly.

Once you have that buffer in place, start building toward a full emergency fund over time while also investing. These two goals can run in parallel. For help sizing your emergency fund, see the General Principles guide.

Priority order for most young adults: 1) Capture the full employer 401(k) match. 2) Build a starter emergency fund. 3) Fund a Roth IRA up to the annual limit. 4) Max out 401(k). 5) Taxable brokerage account.

Step 2: Capture Your Employer's Full 401(k) Match

If your employer offers a 401(k) match, contribute at least enough to capture it before doing anything else. A match is the closest thing to a guaranteed, immediate return that exists in investing. Not contributing enough to receive the full match is turning down part of your compensation.

The most common match formula is something like "100% of the first 3% of salary" or "50% of the first 6%." The specifics are in your HR benefits portal. Find your match formula, confirm what percentage you need to contribute to get it all, and make sure your contribution is set to at least that amount.

Step 3: Open a Roth IRA

For most young adults who are earlier in their careers and in a lower tax bracket, a Roth IRA is one of the best accounts available. You contribute after-tax money, and all growth and qualified withdrawals in retirement are completely tax-free. Given that your income — and therefore your tax rate — is likely to be higher in the future, locking in today's lower rate is a significant advantage.

You can open a Roth IRA at any major brokerage. The process takes about 15 minutes. You can contribute up to the annual IRS limit each year, and there are income limits for direct contributions — check the current IRS guidelines to confirm you are eligible. Once the account is open, you decide what to invest in. Which brings us to the next step.

Step 4: Invest in Low-Cost Index Funds

Index funds are the default choice for most evidence-based investors — including many financial professionals. An index fund tracks a broad market index, like the S&P 500 or the total US stock market, and holds every company in proportion to its size. Because there is no active management involved, the fees are extremely low — often less than 0.05% per year.

Study after study has found that most actively managed funds, where a professional tries to pick winning stocks, underperform their benchmark index after fees over long periods. S&P Global's SPIVA reports track this annually and the numbers are consistent: index funds beat the majority of active managers over 10- and 15-year windows. That is why they are the standard starting point for beginner investors.

A simple starting portfolio might look like: a US total market index fund, an international stock index fund, and a bond index fund. The mix depends on your time horizon and risk tolerance. The Simple Portfolio Builder in our investing guide generates a concrete recommendation based on your situation.

On market volatility: Markets drop. Sometimes significantly. A well-diversified index fund portfolio held for 20+ years has historically recovered from every downturn. The investors who get hurt most are those who panic and sell during the drop. Staying invested through bad stretches is how most of the long-term gains get captured.
