Investing: Beginner's Guide for Gen Z

By FiscallyAI Editorial (AI-assisted) • Updated 2026-02-19 • Educational content

Build long-term wealth through investing. Start early, stay consistent, and let compound growth do the heavy lifting.

Why Investing Matters

Saving alone won't make you wealthy. Inflation erodes cash over time. Investing allows your money to grow faster than inflation, building real wealth over decades.

For Gen Z, your biggest advantage is time. Starting at 22 vs 32 can mean hundreds of thousands of dollars difference by retirement, even with the same contributions.

How Compound Interest Works

Compound interest is interest earned on interest. When your investments grow, those gains generate their own gains. Over time, this creates exponential growth.

Example: $300/month at 7% Annual Return

Starting Age	Until Age 65	Total Contributions	Final Balance
22	43 years	$154,800	$1,100,000+
27	38 years	$136,800	$770,000+
32	33 years	$118,800	$540,000+
37	28 years	$100,800	$370,000+

Starting 5 years earlier: +$330,000. Starting 10 years earlier: +$560,000.

Investment Account Types

Retirement Accounts (Tax-Advantaged)

Account	2026 Limit	Best For
401(k)	$23,500	Get employer match first; tax-deferred growth
Roth IRA	$7,000	Tax-free growth & withdrawals; ideal for young investors
Traditional IRA	$7,000	Tax deduction now; pay taxes in retirement

Taxable Brokerage Accounts

After maxing retirement accounts, use a regular brokerage. You'll pay taxes on gains, but you can withdraw anytime without penalty.

What to Invest In

Index Funds (Recommended for Most People)

Index funds track a market index (like the S&P 500) and provide instant diversification. They're low-cost, passive, and historically beat most actively managed funds.

S&P 500 Index Fund — Tracks 500 largest US companies
Total Stock Market Fund — Tracks entire US market
Total International Fund — Diversifies beyond US
Target-Date Funds — Automatically adjusts as you age

What to AVOID as a Beginner

Individual stocks — Risky, requires research, underperforms indexes long-term
Crypto — Extremely volatile; if you must, limit to 1-5% of portfolio
Day trading — Most people lose money
High-fee funds — Expense ratios over 0.5% are too high

Dollar-Cost Averaging

Dollar-cost averaging (DCA) means investing a fixed amount regularly, regardless of market conditions. This removes the stress of trying to time the market.

Why DCA Works

Buy more shares when prices are low
Buy fewer shares when prices are high
Average cost per share evens out over time
Removes emotional decision-making

Common Investing Mistakes

Waiting to "have enough" — Start with $50. Waiting costs you years of growth.
Trying to time the market — Time IN the market beats timing THE market.
Selling in panic — Every market drop looks like an opportunity in hindsight.
Checking too often — Daily fluctuations are noise. Check monthly or quarterly.
High fees — A 1% fee can cost you $100K+ over a lifetime.
