Compound Interest Calculator

Compound interest is calculated using the compound interest formula: A = P(1+r/n)^nt. For annual compounding, multiply the initial balance by one plus your annual interest rate raised to the power of the number of time periods (years). This gives a combined figure for principal and compound interest.
