Work & Installation — Input to Output Summary
Work: Calculates future value using compound interest formulas: FV = P × (1 + r/n)^(n × t) + PMT × [((1 + r/n)^(n × t) – 1) / (r/n)] Where P = initial investment, r = annual return rate, n = compounding periods per year, t = investment duration, PMT = recurring contributions.
Installation: Online tool—no installation required.
Input: Initial Investment, Annual Return Rate (%), Investment Duration (Years), Compounding Frequency, Optional Recurring Contributions.
