How to Start Investing in Your 20s: What I Wish I Knew at 22

A practical guide to investing in your 20s based on my real mistakes and wins. What to buy, how much to save, and what to skip.

By Galchaebi

I started investing at 26. That means I wasted four years of compound growth — years I can never get back. Between ages 22 and 26, I earned roughly $180,000 in total income and invested exactly $0 of it. If I had invested even 10% during those years, I’d have an extra $25,000-30,000 in my portfolio today.

I don’t write this to guilt-trip anyone. I write it because the reasons I didn’t invest at 22 are the same reasons most people in their 20s don’t invest: I thought I didn’t make enough money, I thought investing was complicated, and I thought I’d “start later when I had more.”

Later came. I did have more. But I also had four fewer years of compound interest — and that’s a gap that never fully closes.


Why Your 20s Are the Most Powerful Investing Decade

Compound interest is the most cited concept in personal finance, and also the most underappreciated. Here’s a concrete example that changed how I think about time and money:

The Power of Starting Early: Two Investors

Investor A (starts at 22)Investor B (starts at 32)
Monthly investment$300$300
Annual return8%8%
Investing periodAge 22-62 (40 years)Age 32-62 (30 years)
Total contributed$144,000$108,000
Portfolio at age 62$1,045,000$447,000

Investor A contributes only $36,000 more than Investor B — but ends up with $598,000 more at retirement. That extra money isn’t from contributions. It’s from compound growth having 10 additional years to work.

The math is unambiguous: time in the market matters more than the amount you invest. A 22-year-old investing $200/month will likely outperform a 35-year-old investing $500/month by retirement. That’s the advantage you have in your 20s — and it evaporates every year you wait.


The 5 Mistakes I Made (So You Don’t Have To)

Mistake 1: Waiting Until I “Had Enough”

At 22, I thought investing required thousands of dollars. I imagined people in suits buying stocks in blocks of 100 shares. In reality, you can start investing with $1 through fractional shares at any major brokerage. The $100/month I spent on things I can’t even remember would have been worth over $10,000 today.

Mistake 2: Keeping All My Money in a Checking Account

For four years, my savings sat in a checking account earning 0.01% interest. Even a basic high-yield savings account would have been better. But what I really should have done was invest that money in an index fund. Cash feels “safe,” but inflation silently erodes its purchasing power by 2-3% every year.

Mistake 3: Not Understanding Tax-Advantaged Accounts

I didn’t open a Roth IRA until I was 27. I didn’t know what a 401(k) match was until 28. These are the most powerful wealth-building tools available to young investors, and I ignored them for years because nobody explained them in plain English.

Mistake 4: Trying to Pick Individual Stocks First

My first investment was an individual stock pick based on a Reddit recommendation. It dropped 40%. This nearly scared me away from investing entirely. If my first investment had been a boring index fund, my early experience would have been much smoother — and I probably would have started investing more aggressively sooner.

Mistake 5: Thinking I Needed to “Learn More” Before Starting

I spent months reading investing books, watching YouTube videos, and following finance influencers. All of that learning was valuable — but it also became a form of procrastination. I was learning about investing instead of actually investing. The truth is, you learn more from your first $500 in the market than from 500 hours of content consumption.


The Simple Investing Plan for Your 20s

If I could go back to age 22, here’s the exact plan I’d follow:

Step 1: Get the Free Money (401k Match)

If your employer offers a 401(k) match, contribute enough to get the full match. This is the closest thing to free money that exists. A typical match is 50% up to 6% of your salary — meaning if you earn $50,000 and contribute $3,000 (6%), your employer adds $1,500 for free. That’s an instant 50% return before the market even moves.

Step 2: Open a Roth IRA

A Roth IRA is the most powerful investment account for people in their 20s. Here’s why:

  • You contribute after-tax dollars, so all future growth is tax-free
  • You can withdraw contributions (not gains) at any time without penalty
  • In your 20s, you’re likely in a lower tax bracket than you will be later — paying taxes now at a low rate beats paying taxes later at a higher rate
  • 2026 contribution limit: $7,000/year ($583/month)

Fund your Roth IRA with a total market index fund like VTI. That’s it. One fund, one account, automatic contributions on payday.

Step 3: Invest What’s Left in a Taxable Brokerage

If you’ve maxed your employer match and your Roth IRA and still have money to invest, open a taxable brokerage account. Same strategy — buy VTI or VOO. The tax treatment is less favorable than a Roth, but it’s infinitely better than leaving money in a checking account.

Step 4: Increase Contributions With Every Raise

This is the one habit that separates people who build wealth in their 20s from those who don’t. Every time you get a raise, increase your investment contributions by at least half the raise amount. If you get a $200/month raise, invest an extra $100/month. Your lifestyle improves slightly, and your investment trajectory improves dramatically.


What to Actually Buy: The One-Fund Portfolio

In your 20s, you don’t need a complex portfolio. You need two things: broad diversification and low costs. One fund gives you both.

The Case for VTI (Vanguard Total Stock Market ETF)

FeatureDetail
Number of holdings4,000+ stocks
Expense ratio0.03% ($3 per $10,000 invested)
DiversificationEvery sector of the U.S. economy
Historical return~10% average annual return
Minimum investment$1 (fractional shares)

VTI owns essentially every publicly traded company in the United States. When you buy VTI, you’re buying Apple, Microsoft, and Amazon — but also thousands of smaller companies that might become the next big winners. You don’t need to pick which companies will succeed because you own all of them.

Alternatives

  • VOO (S&P 500 ETF): If you prefer to own just the 500 largest companies instead of the total market. Performance is nearly identical to VTI over long periods.
  • VT (Total World Stock): If you want international diversification included. Owns stocks from every developed and emerging market worldwide.

What You Don’t Need in Your 20s

  • Bonds (you have 40 years until retirement — you can handle volatility)
  • Sector-specific ETFs (you’re not trying to time sectors)
  • Individual stocks (unless you’ve maxed your index fund contributions first)
  • Crypto (treat it as speculation, not investment, and never more than 5% of your portfolio)

How to Handle Market Crashes in Your 20s

You will experience market crashes. The S&P 500 has dropped 20%+ roughly once every 5-7 years throughout its history. In your 20s, you will likely live through at least two significant downturns.

Here’s the counterintuitive truth: market crashes in your 20s are the best thing that can happen to you. Every dollar you invest during a crash buys more shares at lower prices. Those shares will have decades to recover and compound.

My Experience With the 2022 Bear Market

When the market dropped 25% in 2022, I was terrified. My portfolio went from $18,000 to $13,500. I seriously considered selling everything and waiting for the bottom.

I didn’t sell. Instead, I kept my automatic investments running. The shares I bought during the 2022 lows are now my best-performing purchases, up over 60% from their crash-day prices.

If I had sold at the bottom and waited to “feel safe” before reinvesting, I would have missed the recovery and locked in my losses permanently. This happens to millions of investors every crash cycle.

The rule is simple: in your 20s, buy consistently and never sell during a downturn. You have decades for recovery. Time is your greatest asset.


Investing on a Low Income: It’s Still Worth It

“But I only make $35,000 a year. Is it even worth investing?”

Yes. Here’s why.

$50/Month Is Not Nothing

$50/month invested in VTI from age 22 to 62 at 8% average returns grows to approximately $174,000. That’s $174,000 from contributions totaling $24,000. The other $150,000 is pure compound growth.

You might not feel like $50/month matters. But your future self, sitting on $174,000, would strongly disagree.

Focus on Income Growth, Not Just Saving

In your 20s, your biggest financial lever is your earning potential. A $10,000 raise that you invest half of ($5,000/year) has a bigger impact on your wealth trajectory than any clever investment strategy. Invest in your career — skills, certifications, networking, job-hopping for raises — and let increasing income fund increasing investments.


Frequently Asked Questions

How Much Should a 25-Year-Old Have Invested?

There’s no single “right” number, but a common benchmark is having the equivalent of one year’s salary saved and invested by age 30. If you earn $50,000, aim for $50,000 in total investments by 30. If you’re behind, don’t panic — the most important thing is starting now and investing consistently.

What Is the Best Investment for a 22-Year-Old?

A total stock market index fund (VTI or VOO) in a Roth IRA is the optimal first investment for most 22-year-olds. It provides broad diversification, extremely low costs, and the tax-free growth of a Roth IRA maximizes the benefit of your long time horizon.

Is 25 Too Late to Start Investing?

Absolutely not. While starting at 22 is ideal, starting at 25 still gives you 37-40 years of compound growth before retirement. The difference between starting at 22 and 25 is meaningful but manageable — far less significant than the difference between starting at 25 and not starting at all.

Should I Invest or Save for a House in My 20s?

Both, if possible. Fund your Roth IRA first (the growth is tax-free and you can withdraw contributions for a home purchase). Then save for a house down payment in a high-yield savings account. If you can only choose one, invest — renting is not “throwing money away,” and the compound growth from early investing is hard to replicate later.


Bottom Line

Your 20s are the most valuable investing years you’ll ever have — not because you have the most money, but because you have the most time. Every dollar invested at 22 has 40 years to compound. Every dollar you wait to invest has less. The strategy is simple: get your employer match, max your Roth IRA, buy a total market index fund, and increase your contributions with every raise. You don’t need to be an expert. You just need to start.

I wasted four years before I figured this out. You don’t have to.
