The Magic of Compound Interest
This calculator demonstrates the power of compound interest, which Albert Einstein reportedly called the "eighth wonder of the world." It's the process where you earn interest not only on your initial principal but also on the accumulated interest from previous periods.
Key Principles:
- Start Early: The longer your money is invested, the more time it has to grow. Even small amounts can grow significantly over several decades.
- Contribute Regularly: Making consistent contributions, no matter how small, dramatically increases your end balance. It's the key to building wealth over time.
- Interest Rate Matters: A higher rate of return can make a substantial difference in the long run. The S&P 500 has historically returned an average of around 10% per year, though past performance is not indicative of future results.
- Compound Frequency: More frequent compounding (daily vs. annually) results in slightly higher returns, though the difference is usually modest.
