Growth Projection Analysis
Compound Interest Formula
A = P(1 + r/n)nt + PMT × [(1 + r/n)nt – 1] / (r/n)
Future value (A) is calculated based on principal (P), monthly contributions (PMT), annual return (r), compounding periods (n), and time in years (t). Compound interest accelerates growth over long periods.
