Compound Interest Calculator

Our Compound Interest Calculator is a friendly, easy-to-use tool that instantly shows how your savings can grow over time. Compound interest turns small deposits into significant sums over time, and this informs you about it. 

Earning interest on both the principal and accrued interest is known as compound interest. Each compounding cycle adds interest back into the balance. Growth accelerates compared to simple interest, where interest applies only to the initial amount. This effect makes compounding interest such a powerful force for savers and investors.
