Compound Interest Calculator – Calculate Your Savings and Investments
A Compound Interest Calculator is a powerful online tool that helps you understand how your money can grow over time. Whether you are saving for retirement, planning investments, or just curious about how interest accumulates, this calculator allows you to compute the total amount your money will reach based on principal, interest rate, time, and compounding frequency.
What Is a Compound Interest Calculator?
A Compound Interest Calculator determines the future value of an investment or savings account by applying the interest not only to your initial principal but also to the accumulated interest from previous periods. This “interest on interest” effect can significantly increase your returns over time, making compound interest one of the most powerful tools in personal finance.
How the Compound Interest Calculator Works
The calculator uses the standard compound interest formula:
A = P × (1 + r/n)^(n × t)
Where:
- A = the future value of the investment, including interest
- P = principal amount (initial investment)
- r = annual interest rate (in decimal form)
- n = number of times interest is compounded per year
- t = time in years
By entering your principal, interest rate, number of years, and compounding frequency, the calculator instantly shows how your investment grows over time. Some calculators also allow you to include regular contributions for even more accurate projections.
