You do not need thousands of dollars to start investing. Many people delay investing for years because they think they need a large sum to get started. That belief costs them years of compound growth. Here is how to begin investing today, regardless of how little you have.
Why Starting Small Still Works
The most powerful force in investing is time, not the amount you start with. A $50 monthly investment started at age 25 will grow far more than a $500 monthly investment started at age 40, assuming the same rate of return. Starting early and staying consistent is more important than the amount of your initial investment.
Compound growth means your returns earn returns. The longer money is invested, the faster it grows. Even small amounts benefit from this effect.
Step 1: Build a Small Emergency Fund First
Before investing, put aside $500 to $1,000 in a high-yield savings account. This is your emergency fund starter. Without it, any unexpected expense will force you to sell your investments at the wrong time to cover costs.
You do not need a full 3 to 6 month emergency fund before you start investing. A starter buffer of $500 to $1,000 is enough to begin. Build both at the same time once you have that initial cushion in place.
Step 2: Contribute to Your 401(k) Up to the Match
If your employer offers a 401(k) with a matching contribution, this is the highest priority. An employer match is a 50 to 100 percent guaranteed return on your investment instantly. No investment in the world offers a better return than free money from your employer.
Contribute at least enough to capture the full match. For example, if your employer matches 100 percent of contributions up to 3 percent of your salary, contribute at least 3 percent. Anything less leaves free money on the table.
Step 3: Open a Roth IRA
After capturing your full employer match, open a Roth IRA. You can contribute up to $7,000 per year in 2026 ($8,000 if you are 50 or older). There is no minimum contribution. You can start with $25 or $50.
A Roth IRA is funded with after-tax dollars. Your money grows tax-free, and withdrawals in retirement are tax-free. For most people who are just starting to invest and are in a lower tax bracket, a Roth IRA is the best place to put money after the employer match.
Open a Roth IRA at Fidelity, Vanguard, or Charles Schwab. All three have no account minimums and offer fractional share investing so you can start with any dollar amount.
Step 4: Choose Simple Investments
Do not overcomplicate your investment choices when you are starting small. One or two index funds is all you need. Good starting points:
- A total U.S. stock market index fund: Tracks the entire U.S. stock market, including large, mid, and small companies. Examples: Fidelity ZERO Total Market Index Fund (FZROX), Vanguard Total Stock Market ETF (VTI).
- An S&P 500 index fund: Tracks the 500 largest U.S. companies. Examples: Fidelity 500 Index Fund (FXAIX), Vanguard S&P 500 ETF (VOO).
- A target-date fund: A single fund that automatically adjusts its stock and bond mix as you get closer to retirement. If your target retirement is 2055, you would buy a 2055 target-date fund. This is the simplest choice of all.
How to Invest With $100 or Less
Fractional Shares
Most major brokerages now let you buy fractional shares. This means you can invest $10 or $25 in a stock or ETF regardless of the share price. You do not need to buy a full share. Fidelity, Schwab, and Robinhood all offer fractional shares.
Robo-Advisors
A robo-advisor is an automated investment service. You answer questions about your goals and risk tolerance, and the service builds and manages a diversified portfolio for you. Betterment and Wealthfront are two of the most popular options. Both have low minimums and charge about 0.25 percent annually. This is a good option if you want everything handled for you.
Round-Up Apps
Apps like Acorns round up your purchases to the nearest dollar and invest the spare change. If you spend $3.60 on coffee, Acorns rounds it up to $4 and invests the $0.40. This is a passive way to invest small amounts consistently. The amounts are small, but the habit is valuable, especially for people who struggle to save.
What Not to Do With a Small Amount
- Do not buy individual stocks: Picking individual stocks requires research, time, and a tolerance for concentrated risk. With a small amount, one bad pick wipes out a significant portion of your portfolio. Stick to index funds.
- Do not buy cryptocurrency: Crypto is extremely volatile. It is not an appropriate starting investment for someone with limited funds and no investing experience.
- Do not wait until you have more money: This is the most common and most costly mistake. Start with whatever you have. The habit of investing is worth more than waiting for the “right” amount.
- Do not pay high fees: Avoid any investment fund with an annual expense ratio above 0.5 percent. High fees destroy returns, especially on small accounts.
How to Increase Your Investment Over Time
The goal is to automate your investing so it happens without thought. Set up an automatic monthly transfer from your checking account to your Roth IRA. Increase the amount every time you get a raise. Direct at least half of any bonus or tax refund into your investment account.
Building an investing habit is more important than the amount. Once investing becomes automatic, increasing it becomes easy.
