Compound Interest Calculator
Introduction
A compound interest calculator helps you estimate how your money grows over time when interest is added to both the principal and accumulated interest. It is widely used for investment planning, savings growth, and long-term financial goals. Unlike simple interest, compounding allows your money to grow faster, making it an essential concept for anyone looking to build wealth over time.
How Compound Interest Works
Compound interest is calculated using a standard formula based on the principal, interest rate, time period, and compounding frequency. The formula is:
A = P (1 + R/N) ^ (N × T)
Where P is the principal amount, R is the annual interest rate, N is the number of times interest is compounded per year, and T is the time in years. The result shows the total amount accumulated after compounding, including interest earned on interest.
