Understanding Compound Interest
The Power of Time
Time is your greatest asset in compound interest. The earlier you start investing, the more time your money has to grow exponentially.
Regular Contributions
Consistent contributions amplify the compound effect. Even small amounts added regularly can lead to significant growth over time.
Compound Frequency
More frequent compounding (daily vs. annually) can increase your returns. However, the difference becomes less significant at higher frequencies.
