Maturity Value (A) = P × (1 + r/n)nt + PMT × [ ( (1 + r/n)nt − 1 ) ÷ (r/n) ]
Where P = Initial Principal, PMT = Periodic Investment, r = Annual Return Rate (CAGR), n = Compounding Periods/Yr, t = Years.

Key Parameters & Analytical Variables

Financial Variable Definition & Computational Role
Initial / Periodic Investment Base capital deposited upfront or added systematically each month/year.
Expected Return (CAGR %) Annual compound growth rate based on asset class historical benchmarks.
Investment Tenure (Years) Total accumulation duration allowing exponential compounding to compound.
Ending Maturity Corpus Total cumulative wealth accumulated (Total Capital Invested + Compound Wealth Gain).
