About this calculator
Compound interest is calculated as Principal × (1 + rate÷12)^months for the initial amount, plus the future value of any monthly contributions added along the way.
Because interest is calculated on interest already earned, growth accelerates over time — the longer the time horizon, the bigger the gap between compound and simple interest.
