Overview
Compound interest is the foundation of long-term wealth creation. Unlike simple interest that only grows on your principal, compound interest grows on both your principal and the accumulated interest — creating exponential growth over time. Our Compound Interest Calculator lets you model exactly how any investment will grow given a starting amount, annual interest rate, compounding frequency, and time period. Whether you are planning for retirement, a child's education, or comparing different investment options, this tool gives you precise projections.
