How I Started Investing in the US Stock Market as a Beginner in 2025

I used to think investing was something you needed a suit, six figures, or a Wall Street mentor for. I genuinely believed it wasn’t for people like me — just a regular 20-something trying to make ends meet.

I was wrong.

In this post, I’ll walk you through exactly how I — a total beginner — started investing in the US stock market in 2025. No finance degree, no crypto hype, no overnight gains. Just honest lessons, realistic steps, and a story that might sound a lot like yours.

Why I Put Off Investing for So Long

Let’s be real: investing sounds intimidating when you’re broke or just figuring out adulting. Rent, bills, groceries… then someone says “diversify your portfolio” and you’re like, bro, I’m trying to diversify my ramen flavors.

I was stuck in that mindset for years. I’d read headlines like “S&P Hits All-Time High” and think, “Cool for them. Not my world.”

Also? Fear. I was scared of losing money. I thought investing meant gambling — one wrong move and poof, your savings vanish. So, I did nothing.

The Day I Finally Decided to Learn

It wasn’t a motivational speech or TikTok guru that flipped the switch. It was seeing my older cousin — who makes less than I do — share a screenshot of his investment gains.

“Wait, you’re investing? How? You’re broke like me.”

He laughed and said, “I started with $100 a few months ago. I just learned the basics and stuck to a plan.”

That night, I stayed up reading — everything from Start Building Wealth with $100 to YouTube explainer videos. I promised myself: This month, I will start — even if it’s small.

Stock Market Basics I Had to Understand First

What is a stock?

A stock is just a tiny piece of ownership in a company. If you buy one share of Apple, you own a piece of Apple. If the company does well, your stock might go up in value. If it tanks? You feel it.

What are ETFs and mutual funds?

ETFs (Exchange-Traded Funds) are like bundles of many different stocks. Instead of picking one company, you invest in a basket — which makes it less risky. Mutual funds are similar but usually require a fund manager and sometimes higher fees. I stuck with ETFs.

What does risk really mean?

Risk = chance of losing money. But also: chance of gaining money. High-risk means higher reward or loss. Low-risk is slow and steady. Once I understood that I could manage risk with time and diversification, I stopped freaking out.

How I Picked My First Brokerage (No Robinhood Hype)

Everyone online screams “Robinhood!” but I wanted something safer and more traditional.

After comparing a few (and reading horror stories), I picked Fidelity. No fees for basic trades, beginner-friendly dashboard, and solid reputation.

Other good ones: Charles Schwab, Webull, and SoFi.

Signing up took 15 minutes. I linked my bank, deposited $100, and just stared at the balance. It was real now.

Setting My First Goal: $500 in 30 Days

To build momentum, I gave myself a goal: invest $500 in the next month.

Here’s how I did it:

• Cut Uber completely and biked to work = saved $100
• Switched from takeout to meal prep = saved $150
• Sold two old headphones on eBay = made $90
• Reduced subscriptions = saved $40
• Used tips from Living Frugal: 21 Tiny Habits That Save Thousands

By day 28, I had my $500 — and a weird sense of power I’d never felt with money before.

How I Chose My First Stocks (and Didn’t Panic)

I didn’t touch meme stocks. I didn’t go near crypto. I started with two things:

1. VTI ETF — a total market ETF that invests in the entire US stock market
2. AAPL stock — just one share of Apple, because I understood and believed in the brand

Instead of throwing in the full $500, I did dollar-cost averaging — which just means I invested small chunks ($100/week). It helped me stay calm and avoid buying everything at a “bad” time.

Mistakes I Made — And What I’d Do Differently

Mistakes:

• I checked my portfolio too much. Like 10 times a day. Every red number gave me a mini heart attack.
• I invested emotionally. When a YouTuber hyped a stock, I bought it without research. It dropped.
• I didn’t automate. Manual investing meant I often forgot or spent the money.

What I’d do differently:

• Set recurring transfers into my brokerage
• Stick with boring, steady ETFs
• Remember: I’m investing, not trading

Investing Terms I Wish Someone Explained to Me Sooner

• Dollar-cost averaging: investing small, regular amounts over time — reduces risk of bad timing.
• Index funds: funds that track an entire market index like the S&P 500 — super beginner-friendly.
• Market vs limit order: market buys at current price; limit only buys/sells if your target price hits.

What Helped Me Stay Calm During Market Dips

One day, my Apple stock dropped 4% and I freaked out. I almost sold.

But then I remembered: this is normal. Dips happen. I reread some beginner blogs, like Save $5,000 in the USA by 2025, which reminded me to zoom out — not panic.

Also helpful:

• Followed long-term investors on YouTube, not traders
• Turned off portfolio notifications
• Focused on my why — freedom, security, and building a future

The Results After 3 Months of Investing

Was I rich? Nope. But I had:

• $1,140 invested (grew from that original $500)
• +6.3% gain on my total portfolio
• A completely different mindset about money

The biggest win? I felt like an investor — not a bystander.

What I’d Tell Any Beginner in 2025

Start now. Not later. Not when you “know more.”

Use Start Building Wealth with $100 as a first step.

Keep it simple. Be consistent. Think long term.

And don’t be afraid. If someone like me — who once thought “dividend” was a soda brand — can do this, so can you.
