What is a Compounding Interest Calculator?
A compounding interest calculator is a financial tool that calculates the growth of your investment over time, based on the principal amount, interest rate, time period, and compounding frequency. Unlike simple interest, which only earns interest on the original investment, compounding multiplies your money by reinvesting earned interest.
This calculator is perfect for:
