How Compound Interest Works
One of the most important aspects of retirement savings is compound interest. This means you earn interest not only on your initial investment but also on the interest that accumulates over time.
For example:
- In early years, growth may seem slow
- Over time, the growth accelerates rapidly
- The longer you invest, the greater your returns
This is why starting early is crucial for retirement planning.
