Why Should You Start Investing?

Investing is one of the most powerful tools for building wealth over time. While saving money is important, keeping all your money in a savings account means it loses value due to inflation. Investing allows your money to grow faster than inflation.

The Power of Compound Interest

When you invest, you earn returns not just on your initial investment, but on your returns as well. This is called compound interest, and it's why starting early matters so much.

Example: If you invest $500/month starting at age 25 with an 8% average return, you'll have about $1.4 million by age 65. Start at 35, and you'll have only about $590,000.

Step 1: Set Your Investment Goals

Before you invest, know what you're investing for:

  • Retirement: Long-term, can handle more risk
  • Home down payment: Medium-term, moderate risk
  • Emergency fund: Short-term, keep in savings

Step 2: Choose a Brokerage Account

Popular options for beginners include:

  • Fidelity: No minimums, excellent research tools
  • Vanguard: Pioneer of low-cost index funds
  • Schwab: Great customer service, no minimums

Step 3: Understand Your Options

As a beginner, focus on these investment types:

Index Funds

Low-cost funds that track market indexes like the S&P 500. Warren Buffett recommends these for most people.

ETFs (Exchange-Traded Funds)

Similar to index funds but trade like stocks. Great for diversification.

Target-Date Funds

Automatically adjust your asset allocation as you age. Set it and forget it.

Step 4: Start Small and Be Consistent

You don't need thousands to start. Many brokerages have no minimums. The key is consistency—invest regularly regardless of market conditions (called dollar-cost averaging).

Common Beginner Mistakes to Avoid

  1. Trying to time the market - Even professionals can't do this consistently
  2. Checking your portfolio daily - Long-term investing means ignoring short-term noise
  3. Not diversifying - Don't put all your eggs in one basket
  4. Letting emotions drive decisions - Stick to your plan

Next Steps

  1. Open a brokerage account this week
  2. Set up automatic contributions
  3. Start with a simple index fund or target-date fund
  4. Keep learning and stay the course
