Compound Interest Calculator
Calculate compound interest and total amount easily.
What is Compound Interest?
Compound interest is interest calculated on the original principal as well as the interest accumulated during previous periods. Because the accumulated interest can become part of the amount on which future interest is calculated, the value can grow over time.
What is a Compound Interest Calculator?
A Compound Interest Calculator is an online financial tool that helps calculate the future value of an investment or amount when interest is compounded at regular intervals.
You can enter the principal amount, annual interest rate, compounding frequency and time period to estimate the total amount and compound interest.
Compound Interest Formula
The standard compound interest formula is:
Where:
- A = Final amount
- P = Principal amount
- R = Annual interest rate in decimal form
- n = Number of compounding periods per year
- t = Time in years
Compound Interest Formula in Percentage Form
When the annual interest rate is entered as a percentage, the formula can be written as:
Compound interest can then be calculated as:
How to Use the Compound Interest Calculator

Compound Interest Example
Suppose you invest ₹1,00,000 at an annual interest rate of 8% for 5 years and the interest is compounded annually.
A ≈ ₹1,46,933.28
Therefore, the approximate compound interest is:
≈ ₹46,933.28
What is Compounding Frequency?
Compounding frequency determines how often interest is added to the principal during a year.
- Annually: Interest is compounded once per year.
- Half-Yearly: Interest is compounded twice per year.
- Quarterly: Interest is compounded four times per year.
- Monthly: Interest is compounded twelve times per year.
- Daily: Interest is compounded 365 times per year.
Compound Interest vs Simple Interest
Simple interest is calculated using the original principal amount throughout the calculation. Compound interest can calculate interest on the principal plus previously accumulated interest.
As a result, when other assumptions are the same, increasing the compounding frequency can affect the final amount.
Factors That Affect Compound Interest
- Principal: The initial amount invested or borrowed.
- Interest Rate: The annual rate applied to the amount.
- Time: The length of the investment or loan period.
- Compounding Frequency: How frequently interest is added to the amount.
Why Use a Compound Interest Calculator?
- Calculate compound interest quickly.
- Estimate the future value of an amount.
- Compare different interest rates.
- Compare different compounding frequencies.
- Understand how time affects compound growth.
Important Note
The results provided by this calculator are estimates based on the values entered by the user and the standard compound interest formula. Actual returns, interest and financial outcomes may vary depending on the terms and conditions of the applicable financial product.
Frequently Asked Questions
What is compound interest?
Compound interest is interest calculated on the principal amount and accumulated interest from previous periods.
What is the compound interest formula?
The standard formula is A = P × (1 + R/n)nt, where A is the final amount, P is principal, R is the annual rate in decimal form, n is the number of compounding periods per year and t is time in years.
What is compounding frequency?
Compounding frequency is the number of times interest is added to the amount during one year.
Does compounding frequency affect the final amount?
Yes. When other assumptions remain the same, changing how frequently interest is compounded can affect the calculated final amount.
