Methodology
Compound interest formula: A = P(1 + r/n)^(nt) + PMT × [(1 + r/n)^(nt) − 1] / (r/n). Where P = principal, r = annual rate, n = compounding periods/year, t = years, PMT = periodic contribution. Returns are hypothetical and do not account for taxes, fees or inflation. For educational purposes only.
