What is a Compound Interest Calculator?
A compound interest calculator is an online tool that calculates interest earned on investments in a compounded manner and provides the final value of the investment. An online compound interest calculator simplifies the complex calculations of determining the final value of investments compounded periodically.
This tool simplifies the calculation process by instantly determining the compound interest based on user-provided inputs such as the principal amount, interest rate, compounding frequency, and the time the money is invested for. It provides valuable insights into the total amount an investment will grow to over time, helping in financial planning and decision-making. Compound annual growth rate calculators are widely used to plan for savings, investments, and loans to understand the impact of compounding on financial outcomes.
How Does a Compound Interest Calculator Work?
A compound interest calculator computes the final value of the investment by collecting principal, interest rate, compounding frequency and duration. The compound interest calculator works on the compound interest formula to quickly compute the interest earned and total investment value at the end of the investment period.
To get an estimate of the value of your investments in the future, invested at a compounding rate, all you need to do is:
Enter your investment amount
Enter your expected rate of return
Enter the investment period (in years)
Based on the above-entered details, the calculator will display your total investments at the end of your investment tenure – giving you detailed insights on how much you invested, how much the interest earned and the total investment that you get at maturity, by using the following formula:-
Maturity Amount = P x (1+r)t
Where
P - is the principal amount of investment
r - is the rate of interest applied
T - is the tenure for which you wish to invest
How to Calculate Compound Interest?
How to calculate compound interest? - is one of the most searched queries on the internet when it comes to investment returns. To help you get an idea of how compound interest is calculated, here is a simple example
To know how compound interest is calculated, we must understand what compound interest is. In simple terms, compound interest is an interest that you earn over the interest that you get on your principal investment.
There are two types of interests.
First is the simple interest.
In this case, the interest is generated only on the principal amount
For example, let’s assume you invest 10,000 in a savings account at an annual rate of interest of 5% for 5 years. In this case, the simple interest will be calculated using the following formula
Simple Interest = (Principal Amount × Rate of Interest × Time) / 100
Let’s input our data for the above-required values
Simple Interest = (10,000 x 5 x 5) / 100
Simple interest = (2,50,000)/100
Simple Interest = 2,500
In this example, on an investment of Rs 10,000, you earn a simple interest of Rs 2,500
Consider the same scenario, but in this case, the rate of interest (i.e 5%) is compounded annually, which means, every year for 5 years, you will generate interest over the interest you have earned for the previous year
To calculate the compound interest, we need to use the formula
A = Principal Amount × [(1 + (Rate of Interest / 100))^Time - 1]
Here,
A is the final interest amount that you will receive
P is the principal amount of your investment
R is the rate of interest
n is the number of times the interest is compounded in a year
t is the Tenure of your investment
So, by substituting the values, we get
P = 10,000
r = 5% or 0.05
n = 1 (because in our case the interest is compounded only once a year)
t = 5 years
Let’s replace these values in the above formula, we get
A = Principal Amount × [(1 + (Rate of Interest / 100))^Time - 1]
A = 10,000 [(1 + (5/100))5- 1]
A = 10,000 [(1 + (0.05)) 5- 1]
A = 10,000 [(1 + (0.05)) 5- 1]
A = 10,000 [1.2763 - 1]
A = 10,000 x 0.2763
A = 2,763
Investing through simple interest will give you a return of Rs 2,500, but investing through compound interest will give you 2,763, which is 10% more on the same investment at the same rate for the same period.
This is why you should make your investments in compounding schemes, to earn more and beat the inflation.

How will a compound interest calculator help me plan my finances?
Compound interest is the secret to creating wealth over time. This is because while simple interest earns you returns on your investment alone, compound interest helps you gain added returns on your existing returns. In other words, it is interest on interest, which helps your corpus grow exponentially rather than just linearly.
To understand how much you can earn from an investment that offers compound interest, you need to use a compound interest calculator. This nifty online tool helps you plan your finances in a more informed and efficient manner, since you can get a clear idea of exactly how much your deposit will grow over the investment tenure.
Conversely, you can also use this online financial tool to compare different investment options that offer the benefit of compounding, and figure out which investment avenue can help you achieve your financial goals in a timely manner.
What is the difference between simple interest and compound interest?
Simple interest is the interest that you earn on the principal amount alone. It is computed using the following formula.
Simple interest = (P x R x T) ÷ 100
Here, the following parameters are denoted by the letters:
• P is the principal amount deposited
• R is the rate of interest
• T is the overall tenure of the deposit
On the other hand, compound interest is the interest earned on the principal amount as well as the returns earned up to that period. So, you earn interest on your interest, leading to exponential growth of your capital. Compound interest is calculated using the formula shown below.
Compound interest = P (1 + r/n)nt - P
Here, the following parameters are denoted by the letters:
• P is the principal amount deposited
• r is the rate of interest
• n is the frequency or the number times the interest is compounded annually
• t is the overall tenure of the deposit
When is my interest compounded?
The interest earned on an investment can be compounded on a monthly, quarterly, semi-annual or annual basis. The frequency of compounding varies from one investment to another. So, make sure you check the frequency of compounding before choosing an investment option.
Can I include regular withdrawals?
A regular compound interest calculator does not typically have any input fields for regular withdrawals. However, you can make use of a SWP (Systematic Withdrawal Plan) calculator to compute the returns from your investment in case you want to make regular withdrawals.
What is the effective annual interest rate?
The effective annual interest rate is the rate of the returns actually earned on your investment when you take compounding into consideration.
What is Compound Interest?
Compound interest is interest calculated on the initial principal and also on the accumulated interest of previous periods. In simpler terms, it means earning interest on interest, where the interest is added to the principal amount and future interest calculations are based on the updated total. This compounding effect can lead to significant growth of an investment over time.
What Is Daily, Monthly & Early Compounding?
Sure, here's a simplified explanation:
1. Daily Compounding: This means interest is calculated and added to your account daily. Each day, your interest is based on the updated account balance, including any previously earned interest.
2. Monthly Compounding: In this case, interest is calculated and added to your account monthly. The interest for each month is calculated based on the account balance at the end of the previous month, including any accumulated interest.
3. Early Compounding: This refers to the process where interest is added to the principal amount at the beginning of each compounding period (like daily or monthly). It allows the interest to earn more interest sooner, leading to faster growth of your investment or savings.
What Are Compound Interest Investments?
Compound interest investments refer to financial products or accounts where your earnings accumulate over time through the compounding effect. This means that not only do you earn interest on your initial investment (or principal), but you also earn interest on the interest you've already earned. Over time, this compounding can significantly increase the total value of your investment, making it a powerful tool for long-term savings and wealth building.
