To calculate the future value of your capital when compounding monthly, we can use the formula for compound interest:

$A = P \left(1 + \frac{r}{n}\right)^{nt}$

Where:

• $A$ is the amount of money accumulated after $n$ years, including interest.
• $P$ is the principal amount (initial capital), which is 50 lakhs (5,000,000).
• $r$ is the annual interest rate (in decimal form). Since you're earning 10% monthly, the annual interest rate would be $10\% \times 12 = 120\%$, so $r = 1.20$.
• $n$ is the number of times that interest is compounded per year. Here, $n = 12$ (monthly compounding).
• $t$ is the time the money is invested for, in years, which is 8 years.

Let's calculate the future value.After 8 years, with a monthly compounded interest rate of 10%, your capital would grow to approximately ₹470,61,71,826 (about 470.6 crores).
