How to Invest When You're Broke: Starting With $5, $10, or $20

You don't need thousands to start investing. Here's how to build wealth even on a tight budget.

The biggest investing myth is that you need a lot of money to start. You've probably heard it framed a dozen different ways: "I'll start investing when I have more saved up," or "I only have $20 — what's the point?" The point is everything.

Investing is not about how much you start with. It's about starting. The most powerful force in investing is time, and every day you wait costs you more than the amount you didn't invest.

Here's the truth: you can begin building wealth with $5, $10, or $20. Here's how.

Micro-Investing Apps

Micro-investing apps were built specifically for people who can't invest large sums. These platforms let you invest spare change, set up recurring investments as small as $5, and build a real portfolio without a traditional brokerage minimum.

Acorns is one of the most popular. It rounds up your everyday purchases to the nearest dollar and automatically invests the difference. Buy a $3.75 coffee, and $0.25 goes into your investment account. Over time, those pennies add up — and they're invested in diversified ETF portfolios. Acorns costs $3/month for individual accounts.

Stash lets you invest in fractional shares of individual stocks and ETFs starting with $1. It also has a banking feature that automatically invests a percentage of your purchases. Monthly fees start at $3.

Robinhood offers commission-free investing with no account minimum. You can buy fractional shares of stocks like Amazon or Apple for as little as $1. It doesn't have automatic round-up features, but the zero-minimum and zero-commission structure makes it accessible.

The downside of micro-investing apps is the fee structure. A $3/month fee on a $100 balance is a 36% annual fee — devastating to returns. As your balance grows (aim to get above $1,000), consider migrating to a full brokerage account for better economics.

Index Funds With No Minimums

A common misconception is that index funds require thousands of dollars to open. That used to be true. It's not anymore.

Fidelity ZERO funds have no minimum investment and no expense ratio. Fidelity's Zero Total Market Index Fund (FZROX) and Zero International Index Fund (FZILX) let you invest literally $1. You get instant diversification across thousands of stocks with zero ongoing cost.

Schwab also has no account minimum and offers index funds with very low expense ratios (as low as 0.03%). You can open a Schwab brokerage account and start buying index funds with $1.

Vanguard historically required $1,000–$3,000 minimums for its admiral shares, but now offers ETF versions of its index funds with no minimum — you buy them on the exchange like a stock, for the price of one share (often $100–$500+).

If you can open a brokerage account with $25 and invest in an index fund, you've done more for your financial future than most people ever will.

Your Employer's 401(k) — Even 1% Matters

If your employer offers a 401(k), even contributing 1% of your paycheck is investing. At $40,000 annual income, 1% is just $33/month. That money comes out before taxes, which means your take-home pay drops by less than $33.

More importantly: if your employer offers any matching contribution, you need to capture it. An employer that matches 50% on up to 6% of your salary is giving you a 50% instant return on your investment. That is the best guaranteed return available anywhere.

Even 1–2% in your employer's 401(k) plan is a form of investing. And it happens automatically, which means you can't spend it.

The Roth IRA Strategy for Low Earners

Here's something that surprises many people: the Roth IRA is actually more valuable the lower your income. Here's why.

A Roth IRA is funded with after-tax money. If you're earning $30,000 a year, you're in a low tax bracket — meaning the taxes you're paying now are at a low rate. Money that goes into a Roth IRA grows completely tax-free, and withdrawals in retirement are also tax-free.

You can contribute up to $7,000 per year to a Roth IRA in 2024 (or $8,000 if you're 50+). But you can also contribute just $50/month — there's no minimum contribution requirement once the account is open.

Open a Roth IRA at Fidelity, Schwab, or Vanguard with $0 and contribute whatever you can. Even $50/month at 22 years old, invested in a total stock market index fund, could grow to over $200,000 by retirement at historical average returns.

What to Do Before You Invest

Investing when you're broke requires one crucial preparation step: clear the most expensive debt first.

If you're carrying credit card debt at 20–25% APR, paying that off earns you a guaranteed 20–25% return — better than almost any investment. The exception: always capture your employer's 401(k) match first (that's a guaranteed 50–100% return). Then pay off high-interest debt. Then invest beyond the match.

Also build a $500 buffer in your checking account before investing aggressively. This small cushion prevents you from needing to liquidate your investments to cover a car repair or unexpected bill.

The order of operations:

Contribute enough to your 401(k) to get the full employer match
Pay off high-interest debt (above 10–12% APR)
Build a $500–$1,000 starter emergency fund
Invest via Roth IRA or continue increasing 401(k) contributions

You don't need to be rich to start investing. You need to start investing to eventually become rich.
