About Compound Interest

Compound Interest: Interest calculated on the initial principal and accumulated interest from previous periods.

Compounding Frequency: How often interest is calculated and added to your balance. More frequent compounding (monthly vs. annually) results in higher returns.

Formula: FV = P(1 + r/n)^(nt) + PMT × [((1 + r/n)^(nt) - 1) / (r/n)], where P is principal, r is annual rate, n is compounding frequency, t is time in years, and PMT is periodic contribution.
