How to Start Investing in Your 20s
Last updated: March 2026
Your twenties are the most powerful decade for building wealth because of the time advantage. Learn how to start investing even with a small budget, entry-level income, and student loans.
Step 1: Get Your Financial Foundation in Place
Before investing, cover three basic financial priorities. First, build a starter emergency fund of at least one thousand dollars in a high-yield savings account. This prevents you from selling investments to cover unexpected expenses. Second, pay off any high-interest debt above seven to eight percent, especially credit card balances. No investment consistently earns more than credit card interest rates. Third, if your employer offers a 401k match, contribute enough to get the full match. After these three items are addressed, you are ready to start investing additional money. You do not need to have all debt paid off or a fully funded emergency fund to begin. Getting started early matters more than getting started perfectly.
Step 2: Start with Whatever Amount You Can
You do not need a large sum to begin investing. With fractional shares, you can buy ETFs with as little as one dollar. If you can invest fifty dollars per month, start there. If you can do two hundred, even better. The specific amount matters far less than the habit of investing consistently. A twenty-three-year-old investing just one hundred dollars per month in a total stock market ETF earning ten percent annually will have over six hundred thousand dollars by age sixty-five. Starting that same investment at thirty-three instead of twenty-three reduces the total to roughly two hundred thirty thousand. The ten extra years of compounding are worth more than tripling your monthly amount later.
Step 3: Open a Roth IRA as Your First Account
For most people in their twenties, a Roth IRA is the best first investment account after securing any employer 401k match. You are likely in a lower tax bracket now than you will be later in your career, making after-tax contributions less painful. All growth is tax-free forever. You can withdraw your contributions, but not earnings, at any time without penalty, which provides a psychological safety net. Open a Roth IRA at Fidelity, Schwab, or Vanguard in about ten minutes. Fund it with a monthly automatic transfer from your bank. Even if you cannot max out the annual limit, any amount you contribute starts compounding tax-free.
Step 4: Buy a Single Broad Market ETF
Keep your investment strategy extremely simple in your twenties. Buy a single total US stock market ETF like VTI or a total world stock market ETF like VT. You do not need bonds at this stage because you have decades before retirement. You do not need multiple funds because one broad ETF holds thousands of stocks. Set up an automatic monthly purchase and enable dividend reinvestment. This is the entire strategy. One fund, automatic contributions, dividends reinvested. As your knowledge and portfolio grow over the years, you can add complexity. But right now, starting and being consistent matters infinitely more than having the perfect allocation.
Step 5: Invest Alongside Student Loan Repayment
Many people in their twenties wonder whether to invest or pay off student loans first. If your student loan interest rate is below five percent, which is common for federal loans, you are generally better off making minimum loan payments while investing the difference because stock market returns historically exceed that rate. If your rate is above seven percent, focus on aggressively paying down the debt first. For rates between five and seven percent, it is a judgment call. A balanced approach, splitting extra money between investing and extra debt payments, works well emotionally and financially. Do not delay investing entirely until your student loans are paid off because the lost compounding time is extremely costly.
Step 6: Increase Your Investments as Your Income Grows
Your twenties are a period of rapid income growth as you advance in your career. Each time you receive a raise, promotion, or bonus, increase your automatic investment amount before adjusting your lifestyle. If you get a two hundred dollar per month raise, direct at least half of it to your investments. This prevents lifestyle inflation from consuming all your income gains. By your late twenties, aim to invest fifteen to twenty percent of your gross income. The earlier you establish this habit, the easier it becomes. People who increase their savings rate each year build dramatically more wealth than those who start high but never increase.
Pro Tips
- ✓Starting to invest at twenty-two versus thirty-two can double your retirement wealth because of compound growth over that extra decade.
- ✓A Roth IRA should be your first investment account after capturing any employer 401k match because tax-free growth in your twenties is incredibly valuable.
- ✓One broad market ETF is all you need to start. Do not let the pursuit of the perfect portfolio prevent you from investing now.
- ✓Automate your investments so they happen every month without you needing to make a decision or take action.
- ✓Increase your investment amount with every raise. Direct at least fifty percent of each income increase toward saving and investing.
Common Mistakes to Avoid
- ✗Waiting until you feel financially ready to start investing, which often means waiting years and losing the most valuable compounding time.
- ✗Trying to build a complex multi-fund portfolio from day one instead of starting simply with one broad market ETF.
- ✗Paying off low-interest student loans aggressively while skipping investing entirely, missing years of compound growth.
- ✗Not taking advantage of an employer 401k match, which is free money you can never get back if you miss it.
