The Power of Monthly Compounding

Monthly compound interest accelerates your wealth building by reinvesting your earnings twelve times per year. This frequent reinvestment can significantly boost your returns compared to annual compounding.

Monthly compound interest formula:

\(A = P(1 + \frac{r}{12})^{12t}\)

where:

  • A = Final amount
  • P = Principal investment
  • r = Annual interest rate (decimal)
  • t = Time in years
  • 12 represents monthly compounding frequency
