*You don’t need thousands to start. You need $100 and 20 minutes.*

Here’s the lie you’ve been told your whole life: investing is for rich people.
It’s not. It hasn’t been for years. And if you’re still keeping all your money in a checking account because you think you need $10,000 to get started, you’re leaving money on the table every single day.
This guide is going to walk you through exactly how to start investing with $100 or less. No jargon. No BS. Just the steps.
## Why $100 Is Enough
Thanks to fractional shares, you can buy a piece of any stock for as little as $1. That means:
– **$1 buys you a piece of Amazon**, Apple, Google, or NVIDIA
– **$100 spread across 10 stocks** gives you a diversified portfolio
– **$25/week** invested consistently turns into real money over time
Here’s the math that should wake you up:
| Monthly Investment | 10 Years (10% avg return) | 20 Years | 30 Years |
|—|—|—|—|
| $25/week ($100/mo) | $20,655 | $76,570 | $226,049 |
| $50/week ($200/mo) | $41,310 | $153,139 | $452,098 |
| $100/week ($400/mo) | $82,620 | $306,279 | $904,195 |
That’s not fantasy. The S&P 500 has averaged roughly 10% annual returns over the last century. **$100 per month for 30 years = over $226,000.** That’s the power of compounding, and it works for everyone, not just people with big paychecks.
## Step 1: Choose a Brokerage (5 minutes)
A brokerage is just the app where you buy stocks. Here are the best free options:
### Fidelity (Recommended)
– No minimums, no fees
– Fractional shares starting at $1
– Excellent research tools
– Has retirement accounts (Roth IRA — more on this below)
### Charles Schwab
– No minimums, no fees
– Great customer service
– Solid all-around platform
### Robinhood
– Easiest interface
– Good for beginners
– Fractional shares
– Less research tools than Fidelity
**Our pick: Fidelity.** It’s free, has everything you need, and you can open a Roth IRA there too (the single best account for building wealth — we’ll explain below).
Download the app. Sign up. It takes 5 minutes.
## Step 2: Open a Roth IRA (The Secret Weapon)
Before you start buying stocks in a regular account, open a **Roth IRA**. This is the single best wealth-building tool available to working people. Here’s why:
– **You pay taxes now, never again.** Your money grows tax-free forever.
– **Withdrawals in retirement = $0 in taxes.** That’s huge.
– **You can contribute up to $7,000/year** (2026 limit)
– **You can withdraw your contributions anytime** (not the gains, but what you put in) — so it’s not locked away like a 401k.
If you make under ~$161,000/year (single), you qualify for a Roth IRA. Open one at Fidelity or Schwab.
**This is the move most working people don’t know about.** Your future self will thank you.
## Step 3: Pick Your First Investments ($100)
Don’t overthink this. Here’s a dead-simple starter portfolio:
### The “Set It and Forget It” Approach
Put your entire $100 into **one index fund:**
– **VTI** (Vanguard Total Stock Market ETF) — owns a piece of every US company
– **VOO** (Vanguard S&P 500 ETF) — owns the 500 biggest US companies
That’s it. One fund. You now own a piece of Apple, Google, Amazon, NVIDIA, and 3,500+ other companies. You’re diversified from day one.
### The “I Want to Pick Some Stocks” Approach
If you want to be more hands-on:
| Amount | What | Why |
|—|—|—|
| $50 | VTI or VOO | Your safe foundation |
| $15 | NVIDIA (NVDA) | AI chip leader |
| $15 | Apple (AAPL) | Cash machine, ecosystem moat |
| $10 | TSMC (TSM) | Makes chips for everyone |
| $10 | Your pick | A company you believe in |
**Rule of thumb:** Keep at least 50% in index funds. Use the rest to learn by picking individual stocks.
## Step 4: Automate It (Set and Forget)
The single most important thing you can do: **set up automatic investments.**
Most brokerages let you automatically invest a set amount every week or month. Set up $25/week or $100/month and forget about it.
This is called **dollar-cost averaging** and it’s powerful because:
– You buy more shares when prices are low
– You buy fewer when prices are high
– You never have to time the market
– It removes emotion from investing
**Automate it and stop thinking about it.** Check in once a month if you want, but don’t touch it.
## Step 5: Keep Going
Here’s the real secret: **consistency beats everything.**
It doesn’t matter if the market drops 20% next month. It doesn’t matter if your coworker tells you about the next meme stock. What matters is that you keep putting money in, every single month, for years.
The people who build wealth aren’t the ones who pick the perfect stock. They’re the ones who show up every month and invest regardless.
## Common Questions
**”What about crypto?”**
Keep it under 5% of your portfolio, if at all. It’s speculation, not investing. If you want to throw $20 at Bitcoin for fun, fine. But don’t make it your strategy.
**”What about my employer’s 401k?”**
If your employer matches contributions, **always take the match.** It’s free money. Put in at least enough to get the full match, then put extra money in your Roth IRA.
**”Should I pay off debt first?”**
If you have high-interest debt (credit cards at 20%+), pay that off first. You’ll never earn 20% investing, but you’re “earning” it by not paying interest. Low-interest debt (car loan at 5%) — you can invest and pay the debt at the same time.
**”I’m scared of losing money.”**
The stock market goes down sometimes. That’s normal. Over any 20-year period in history, the stock market has always gone up. You’re not day-trading. You’re building wealth over decades. Short-term drops don’t matter.

6. Retire with way more money than you expected
That’s it. You’re now doing more than 80% of Americans. **The gap between you and a wealthy person isn’t talent or luck — it’s that they started.**
