What is Compound Interest?

Compound interest is the interest calculated not only on the original principal amount but also on the interest accumulated during previous periods. This means your money can grow faster over time because you earn interest on both your initial investment and previously earned interest.

For example, if you invest money at a fixed annual interest rate and the interest is compounded monthly, the interest is added to your balance every month. Future interest is then calculated on this increased balance.

Compound Interest Formula

The standard compound interest formula is:

A = P × (1 + r/n)^nt

Where:

• A = Final amount
• P = Principal amount
• r = Annual interest rate in decimal form
• n = Number of times interest is compounded per year
• t = Time period in years

The compound interest can then be calculated using:

Compound Interest = A − P

How to Use This Compound Interest Calculator?

Using this online compound interest calculator is very easy. Follow these simple steps:

1. Enter your principal amount.
2. Enter the annual interest rate in percentage.
3. Enter the time period for your investment or loan.
4. Select the desired compounding frequency.
5. Click the Calculate button.
6. The calculator will instantly display the final amount and compound interest.

Monthly Compound Interest Calculation

With monthly compounding, the interest is calculated and added to the balance every month. Since there are 12 compounding periods in one year, the annual interest rate is divided by 12 and the total number of periods is calculated based on the number of months.

Monthly compounding can produce a higher final amount than yearly compounding because interest is added to the balance more frequently.

Quarterly Compound Interest Calculation

In quarterly compounding, interest is calculated four times per year. The annual interest rate is divided by 4, and the interest is added to the balance after every three months.

Quarterly compounding is commonly used for certain savings accounts, investments, and financial products.

Yearly Compound Interest Calculation

With yearly compounding, interest is calculated and added to the principal amount once every year. This is one of the simplest forms of compound interest calculation.

Example of Compound Interest Calculation

Suppose you invest ₹10,000 at an annual interest rate of 10% for 2 years, compounded yearly.

Using the compound interest formula:

A = 10,000 × (1 + 10/100)²

The final amount will be ₹12,100, and the compound interest earned will be ₹2,100.

Compound Interest vs Simple Interest

The main difference between compound interest and simple interest is how interest is calculated. With simple interest, interest is calculated only on the original principal amount. With compound interest, interest is calculated on the principal amount plus previously accumulated interest.
