Compound Interest Calculator
Calculate the future value of your investment with compound interest.
What is a Compound Interest Calculator?
A Compound Interest Calculator is a financial tool that helps you understand how your savings or investments can grow over time. Unlike simple interest, which is calculated only on the principal amount, compound interest is calculated on the principal amount and also on the accumulated interest from previous periods. This "interest on interest" effect can significantly boost your savings. This calculator shows you the future value of your money, making it a powerful tool for planning financial goals like retirement, a child's education, or long-term wealth creation.
How to Use the Compound Interest Calculator
To find out the potential future value of your investment, you need to provide a few key details:
- Principal Amount: Enter the initial amount of money you are investing. For example, if you're starting a Fixed Deposit (FD) with ₹1,00,000, enter that here.
- Annual Interest Rate: Input the expected annual interest rate. For instance, if your mutual fund has an expected annual return of 12%, enter '12'.
- Number of Years: Specify how long you plan to keep the money invested.
- Compounds per Year: Enter how many times the interest is compounded annually. For most savings accounts or FDs in India, this is typically quarterly (4), half-yearly (2), or annually (1). For mutual funds, it's often compounded annually.
After entering these values, the calculator will instantly show you the total future value and the total interest earned.

Frequently Asked Questions (FAQ)
Q: What is the rule of 72 in compound interest?
A: The Rule of 72 is a quick way to estimate the number of years required to double your money at a fixed annual rate of interest. Simply divide 72 by the annual interest rate. For example, an investment that has a 12% annual return will double in approximately 6 years (72 / 12 = 6).
Q: Which is better, simple interest or compound interest?
A: Compound interest is almost always better for investors because you earn returns on both your principal and the accumulated interest. This leads to exponential growth over time, whereas simple interest only grows based on the initial principal.
Q: How often is interest compounded in India?
A: It varies. For Fixed Deposits (FDs) in Indian banks, interest is usually compounded quarterly. For savings accounts, it may be daily or quarterly. For investments like mutual funds, returns are typically compounded annually.
