Compound Interest Calculator
Calculate your compound interest.
Enter your details to calculate
Compound interest is a method of calculating interest on your investments that helps to increase the amount of your investment, even when there is only a small amount to start with. Simple interest will only give you interest based on the original amount (principal), while compound interest gives you interest on both the principal and the total amount of interest that has been accumulated up to that point.
Because of this compounding effect, your investment will grow at a much faster pace, and therefore, you will make a much larger profit if you invest for a long period of time. To help you to figure out how much you can expect to make on your investment, a compound interest calculator can be used to apply the compound interest formula to show you what your investment is expected to be worth in the future.
What is Compound Interest?
Compound interest is a financial concept where interest is calculated not only on the original principal but also on the accumulated interest from previous periods.
Compound interest is commonly used in savings accounts, investments, and loans. The total interest depends on how often it is compounded (annually, quarterly, monthly, etc.).
What is a compound interest calculator?
The compound interest calculator calculates how much compound growth you'll get from your savings account or investment over various time intervals, based on the specific interest rates associated with each of those time intervals.
How does a compound interest calculator work?
In order to calculate the compound interest, the compound interest calculator utilises three elements (the principal amount, the interest rate, and the length of time the money is invested) and the compound interest equation.
How is Compound Interest Calculated?
To calculate compound interest, you need these components:
- Principal (P): Initial amount invested or borrowed
- Interest rate (r): Annual rate of interest
- Time (t): Duration (in years)
- Compounding frequency (n): Number of times interest is applied per year
Formula:
A = P (1 + r/n) ^ nt
Where, CI = A - P
Where:
- A = Final amount
- P = Principal
- r = Interest rate
- n = Compounding frequency
- t = Time period
Example of Compound Interest
If you invest ₹1,00,000 at 6% annually:
- After 1 year → ₹1,06,000
- In the next year → interest is calculated on ₹1,06,000
This shows how returns increase faster due to compounding.
Advantages and Disadvantages
Advantages:
- Faster growth of money due to compounding
- Generates passive income
- Helps achieve long-term financial goals
- Ideal for long-term investments
Disadvantages:
- Can significantly increase debt
- Losses can also compound in investments
- Needs time to be effective
- Inflation may reduce real returns
Compound Interest in Loans
When applied to loans:
- Interest is calculated on the loan amount and accumulated interest.
- Includes concepts like:
- Total payment
- Accrued interest
- APR (Annual Percentage Rate)
- Amortisation schedule
This means borrowers may end up paying more over time.
Compound Interest in Investments
For investments:
- Interest is reinvested to grow wealth
- Leads to long-term wealth accumulation
- Growth becomes exponential over time
Using an Online Compound Interest Calculator has numerous advantages
First of all, calculating the Compound Interest Rate can be a long and complicated task when done manually. Secondly, you can make a mistake while performing the manual calculation, which will lead to incorrect results in the end.
In contrast, an online CI calculator is simply easy to use, very accurate, provides a lot of information quickly, and is very reliable.

Frequently Asked Questions
How to use the Compound Interest calculator?
The Compound Interest calculator uses three metrics, the principal amount, interest rate and the time period of money invested, and a mathematical formula, to calculate the Compound Interest.
To use the Compound Interest calculator, you must know these aforementioned three metrics and fill in the correct information in their respective places. The calculator will automatically put in the formula and calculate the Compound Interest for you.
How do you calculate Compound Interest without formula?
Calculating Compound Interest without the formula is a tedious process, as it would have to be calculated as many times as it is compounded for every year & then totaled.
For example, let's say Ankit has Rs. 10,000 in his saving account & he earns 5% interest on it compounded annually, he would simply have to calculate the interest earned every year.
Year 1: 5% of 10,000 = Rs. 500
Year 2: 5% of 10,500 = Rs. 525
Year 3: 5% of 11,025 = Rs. 551.25
And so on. So CI earned in 3 years is Rs. 1,576.25
What are the three steps of calculating Compound Interest?
Using the Compound Interest calculator, you can find the Compound Interest in three steps:
Identify the three metrics used for calculation; the principal amount, interest rate and the time period of money invested.
Insert the values of the metrics in their respective places in the calculator.

Using the Compound Interest calculation formula, you can calculate the Compound Interest with the following steps:
A = P (1 + r/n) ^ nt
CI = A – P
Solve the equation within the brackets.
The number within the bracket is then solved with the exponential number (nt).
This number is multiplied with the principal amount to receive the total amount accrued. The CI is the difference between total amount & principal amount.
How do you calculate Compound Interest monthly?
Compound Interest can be calculated monthly using the same Compound Interest formula:
A = P (1 + r/n) ^ nt – P
CI = A – P
Where:
CI = Compound Interest
A = Total amount accrued
P = Principal Amount/Present Amount
R/r = Rate of Interest
N/n = Number of times interest compounds in a year
T/t = Number of years
However, while calculating monthly, the variable N/n will be 12 for the number of months, hereby making it number of times interest compounds in a year.
For example, you invested Rs. 5,000 in a fixed deposit that compounds interest monthly with a 10% rate of return. The amount invested remains in the fixed deposit for 1 year. Therefore, the values of the variables will be:
P = 5,000
R/r = 0.1
N/n = 12
T/t = 1
Now, putting the values in the formula:
A = 5000 (1 + 0.1/12) ^ 12×1
A = 5523.565
CI = 5523.565 – 5000
CI = 523.565

What are some examples of Compound Interest?
Compound Interest can be calculated using the Compound Interest formula:
CI = P (1 + r/n) ^ nt – P
Where:
CI = Compound Interest
P = Principal Amount/Present Amount
R/r = Rate of Interest
N/n = Number of times interest compounds in a year
T/t = Number of years
For example, you invested Rs. 5,000 in a fixed deposit that compounds interest quarterly with a 10% per annum rate of return. The amount invested remains in the fixed deposit for 5 years. Therefore, the values of the variables will be:
P = 5,000
R/r = 0.1
N/n = 4
T/t = 5
Now, putting the values in the formula:
CI = 5000 (1 + 0.1/4) ^ 4×5 – 5000
CI = 3,193.08
So, in 5 years, you will have a total of Rs. 8,193.08.
Here is another example for calculating Compound Interest. Imagine you have put Rs. 10,000 in your savings account for 10 years, earning 5% interest per year. Our compounding in this case is yearly. Therefore, the values of the variables will be:
P = 10,000
R/r = 0.05
N/n = 1
T/t = 10
Now, putting the values in the formula:
CI = 10000 (1 + 0.05/1) ^ 1×10 – 10000
CI = 6,288.946
So, in 10 years, you will have a total of Rs. 16,288.946.

What is the formula of Compound Interest annually?
Compound Interest can be calculated annually using the same Compound Interest formula:
A = P (1 + r/n) ^ nt – P
CI = A – P
Where:
CI = Compound Interest
A = Total amount accrued
P = Principal Amount/Present Amount
R/r = Rate of Interest
N/n = Number of times interest compounds in a year
T/t = Number of years
However, while calculating annually, the variable N/n will be 1, hereby making it number of times interest compounds in a year.
For example, you invested Rs. 5,000 in a fixed deposit that compounds interest monthly with a 10% rate of return. The amount invested remains in the fixed deposit for 1 year. Therefore, the values of the variables will be:
P = 5,000
R/r = 0.1
N/n = 1
T/t = 1
Now, putting the values in the formula:
A = 5000 (1 + 0.1/1) ^ 1×1
A = 5500
CI = 5500 – 5000
CI = 500
