How This Is Calculated
This page uses the compound interest formula with monthly compounding to project investment growth:
A = P(1 + r/n)nt
Where P = $$10,000 (initial investment), r = 0.06 (annual return rate), n = 12 (compounding periods per year — monthly), and t = 20 (years).
Substituting: A = 10,000 × (1 + 0.005000)240 = $33,102.
Compound interest formula: A = P(1+r/n)^(nt). Monthly compounding (n=12). No periodic contributions or withdrawals.
