Introduction to Investing

Investing is how your money grows while you sleep. Instead of just saving, you put your money to work -- buying assets that increase in value over time. It's the difference between a piggy bank and a money machine.

You don't need to be rich or a Wall Street expert. You just need to understand the basics and start early. Let's demystify investing.

Historically, the S&P 500 has returned about 10% annually over the long term. A $200/month investment starting at age 25 can grow to over $1 million by retirement.

The Power of Compound Growth

Compound growth means you earn returns on your returns. Year 1, your $1,000 earns $100. Year 2, you earn on $1,100. The longer you stay invested, the more dramatic the snowball effect.

This is why time in the market matters more than timing the market.

Risk vs Reward

Every investment carries risk. The general rule: higher potential returns = higher risk. The key is finding the right balance for your age, goals, and comfort level.

Investment Accounts

Where you invest matters almost as much as what you invest in. The right account type can save you thousands in taxes.

💼
401(k)
Employer-sponsored, often matched
🎯
Roth IRA
After-tax, grows tax-free
💰
Traditional IRA
Pre-tax, taxed on withdrawal
📊
Brokerage Account
No limits, no tax advantages

Priority order: 1) 401(k) up to employer match (free money!), 2) Max out Roth IRA ($7,000/yr), 3) Max out 401(k) ($23,500/yr), 4) Taxable brokerage for the rest.

The employer match is free money. If your employer matches 100% up to 3% of salary, and you earn $60k, that's $1,800/year free. Not contributing? You're declining a 100% return on investment.
