About the Compound Interest & Retirement Calculator
Compound interest means you earn returns on both your original money and on the returns already earned. Enter a starting balance, a monthly contribution and an expected annual return to see how savings can grow over decades. The inflation setting shows the future balance in today's purchasing power, which gives a more realistic picture for retirement planning.
