How compound interest works
Compound interest is interest calculated on both the initial principal and the accumulated interest from previous periods. This creates a "snowball effect" where your money grows exponentially over time.
The formula: A = P(1 + r/n)^(nt)
- A = Final amount
- P = Principal (initial investment)
- r = Annual interest rate
- n = Compounding frequency per year
- t = Time in years
