📈 The Power of $100 Monthly Investing
Let's look at what happens when you invest $100 every month in SPY (the S&P 500 ETF) over different time periods, assuming a 10% annual return:
Time Period | Total Invested | Final Value | Profit |
---|---|---|---|
5 Years | $6,000 | $7,700 | +$1,700 |
10 Years | $12,000 | $20,500 | +$8,500 |
20 Years | $24,000 | $76,000 | +$52,000 |
30 Years | $36,000 | $226,000 | +$190,000 |
🤯 Mind-blowing fact: Over 30 years, you invest just $36,000 of your own money, but end up with $226,000. That's the power of compound growth!
🎯 Dollar-Cost Averaging with $100 Monthly
When you invest $100 every month, you're using a strategy called dollar-cost averaging (DCA). Here's why it's so powerful:
How Dollar-Cost Averaging Works:
- • Market is high: Your $100 buys fewer shares
- • Market is low: Your $100 buys more shares
- • Over time: You average out the price and reduce volatility
- • Result: Steady growth without trying to time the market
