Estimate the future value of an investment using contributions, growth rate, and time.
The calculator uses compound interest plus monthly contributions:
Future Value = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) − 1) / (r/n)]
Where:
• P = initial investment
• PMT = monthly contribution
• r = annual return rate (decimal)
• n = 12 (monthly compounding)
• t = years invested
Initial Investment = 3,000 Monthly Contribution = 150 Return Rate = 6% Years = 15 Possible Output: Future Value = 55,842.77
