Compound Interest Calculator
Compound interest is a method of calculating interest where the interest earned on an investment is added back to the principal amount, so that interest is calculated on both the initial amount and the accumulated interest from previous periods. This makes compound interest more beneficial than simple interest, especially for long-term investments.
Our Compound Interest Calculator allows you to easily calculate how much interest you will earn or owe over a period of time, factoring in the effect of compounding. Whether you're investing in a savings account, fixed deposit, or loan, the calculator provides flexibility to choose the compounding frequency.
How Does Compound Interest Work?
Compound interest can be calculated on different periods—annually, monthly, weekly, or quarterly. For example, if an investment earns 5% interest per year, this might be broken down into smaller compounding periods, such as 5% per month or 5% per week. This method increases the amount of interest over time as the principal grows with each compounding period.
The formula for compound interest is:
Compound Interest (CI) = P × (1 + r/n)^(nt) - P
Where:
- P = Principal amount (the initial investment or loan amount)
- r = Annual interest rate (as a decimal)
- n = Number of times the interest is compounded per year (e.g., monthly, weekly, or quarterly)
- t = Time (in years)
The Compound Interest Calculator helps you calculate the interest earned or owed over a specified period with different compounding frequencies, such as monthly, weekly, or quarterly. You can enter the principal, rate, time, and the compounding frequency to get the exact compound interest based on your chosen period.

Benefits of Using Compound Interest
- Faster Growth of Investments: Compound interest allows your money to grow faster compared to simple interest, as interest is calculated on both the principal and the accumulated interest.
- More Returns Over Time: The longer your investment stays, the greater the impact of compounding, resulting in more significant returns.
- Reinvesting Earnings: Compound interest encourages the reinvestment of earnings, further enhancing your investment’s value.
- Ideal for Long-Term Investments: Compound interest is particularly effective for long-term investments like retirement funds, stocks, or fixed deposits.
Difference Between Simple Interest and Compound Interest
Simple interest is calculated only on the principal amount, meaning you earn or pay interest on the original investment or loan amount throughout the entire period. In contrast, compound interest is calculated on both the principal and the accumulated interest, which means the interest itself earns interest over time, resulting in higher returns or payments. Essentially, compound interest leads to faster growth of investments compared to simple interest, especially over longer periods.
