Why Invest
A savings account feels safe, but inflation erodes its purchasing power every year. Investing puts your money to work so it grows faster than inflation over time. The most powerful factor in investing isn't picking the right stock — it's time.
A 25-year-old investing $200/month at a 7% average annual return will have roughly $525,000 by 65. Someone starting at 35 with the same contribution reaches only about $243,000. Starting early matters more than starting big.
Pick the Right Account First
The account you use determines your tax treatment — choose before picking investments.
Employer 401(k)
If your employer matches contributions, contribute at least enough to capture the full match. That's an instant 50–100% return — nothing else compares.
Roth IRA
After capturing any 401(k) match, most people under 50 benefit from maxing a Roth IRA ($7,000/year in 2025). Contributions are after-tax, but all growth and withdrawals in retirement are completely tax-free.
Taxable Brokerage
Once tax-advantaged accounts are maxed, a regular brokerage account lets you invest with no contribution limits or withdrawal restrictions.
Order of operations: 401(k) match → Roth IRA → Max 401(k) → Taxable brokerage. Follow this and you'll never leave free money on the table.
What to Invest In
Index Funds
An index fund tracks a market index — like the S&P 500 — and holds a slice of every company in it. Instant diversification at very low cost. Research consistently shows index funds outperform the majority of actively managed funds over 10+ year periods.
ETFs
Exchange-traded funds work like index funds but trade on exchanges like stocks. Low-cost, tax-efficient, and flexible. For most new investors, a simple three-fund portfolio (US stocks, international stocks, bonds) inside low-cost ETFs is all you need.
What to Avoid as a Beginner
- Individual stocks — too much single-company risk
- Actively managed funds with high expense ratios
- Cryptocurrency as a core investment strategy
Getting Started in 3 Steps
- Open an account. Fidelity, Vanguard, and Schwab all offer commission-free accounts with no minimums.
- Choose one fund. A total market index fund (like FSKAX or VTI) is a solid starting point.
- Automate contributions. Even $50/month builds the habit. Set it and forget it.
Time in the market beats timing the market. Don't wait for the "right moment" — the best time to start is today.
Golden Rules
- Never invest money you need within the next 3–5 years
- Don't check your portfolio daily — it encourages emotional decisions
- Keep expenses low — a 1% difference in fees costs tens of thousands over decades
- Stay the course during downturns — missing the recovery is permanent
