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 = $5,000 (initial investment), r = 0.09 (annual interest rate), n = 12 (compounding periods per year — monthly), and t = 20 (years).
Substituting: A = 5,000 × (1 + 0.007500)240 = $30,046.
Compound interest formula: A = P(1+r/n)^(nt). Monthly compounding (n=12). No periodic contributions.
