Estimate the future value of your mutual fund investment.
The future value is calculated using the formula for compound interest with monthly contributions:
FV = P * (1 + r/n)^(nt) + PMT * [((1 + r/n)^(nt) - 1) / (r/n)]
Where P = initial investment, PMT = monthly contribution, r = annual return rate, n = 12 (monthly compounding), t = years.
