High-Yield Savings vs Investing
For short-term goals, savings accounts are safer. For long-term goals, investing significantly outperforms:
| $500/Month For | HYSA (4.5%) | Index Fund (7%) | Index Fund (10%) |
|---|---|---|---|
| 5 years | $33,400 | $35,700 | $38,700 |
| 10 years | $75,400 | $86,500 | $102,400 |
| 20 years | $192,400 | $260,500 | $378,000 |
| 30 years | $367,600 | $584,000 | $1,130,000 |
For goals under 3-5 years, stick with savings accounts. For longer timeframes, investing makes more sense despite short-term volatility.

The Power of Starting Early
Two savers, both investing $500/month at 7%:
| Saver | Starts At | Stops At | Total Contributed | Value at 65 |
|---|---|---|---|---|
| Early Emma | Age 25 | Age 65 | $240,000 | $1,320,000 |
| Late Larry | Age 35 | Age 65 | $180,000 | $584,000 |
Emma contributes only $60,000 more — but ends up with $736,000 more. That’s the power of compound interest over an extra decade.
