The largest private sector bank in India, HDFC Bank is best known for offering a wide range of financial services, including high-yielding fixed deposit schemes. To facilitate secured investment in FD schemes, you can also use an FD calculator and figure out the interest income in advance. This will help you to plan your finances better.

Let’s discuss how to use the HDFC FD calculator to know the interest income and maturity amount of your fixed deposit.

Here is a stepwise process that you need to follow if you want to use the HDFC FD calculator for future financial planning.

Step 1: Enter the Investment Amount

Enter the initial investment amount you want to deposit in your HDFC FD account. You can also use the slide bar to input your desired amount.

Step 2: Enter Tenure of Investment

After selecting a type of HDFC FD scheme, enter the tenure in terms of months or days for your investment. You can also use the slide bar to input the tenure details. The minimum tenure for short-term deposits starts from 7 days, whereas the minimum tenure for other types of deposits is 6 months.

Step 3: Enter the rate of interest

Use the slide bar or simply enter the rate of interest offered by HDFC Bank.  

Once you have entered all your details, the HDFC Bank FD calculator will automatically calculate and show the total investment amount, interest income and total returns on the right-hand side. It is that easy and simple!

An FD calculator helps to determine an FD investment's interest income and maturity amount. It calculates the two while considering the principal amount, tenure of investment, and interest rate.

You can calculate the maturity value of your FD in two ways - the simple interest method and the compound interest method. Let's find out more about these two formulas. 

1. Simple Interest

Under the simple interest method, the amount of interest is only calculated based on the sum of money deposited and the applicable interest rate without using any compounding power. This method has a straightforward formula, where the principal amount is simply multiplied by the rate of interest and tenure.

Simple Interest = (P * R * T)/100

Here, 

• P (₹) = Principal Amount or initial sum of money invested,

• R (%) = Rate of Interest payable by a bank

• T (years/months/days)  = Tenure of an FD scheme.

Let’s see an example to understand how the HDFC fixed deposit calculator uses this method to calculate all returns.

Suppose you have invested ₹50,000 in an HDFC FD scheme for 8 years, with an applicable interest rate of 7%.

Using this simple interest method, we can find out the interest you will earn and the maturity value of your investment after 8 years.

Here, Principal Amount (sum of money to be invested) = ₹50,000, Rate of Interest (payable by a bank) = 7% and Tenure (the time period of an FD investment) = 8 years.

So, by putting the values in the formula, 

Simple Interest = ₹(50,000 * 7 * 8) /100 = ₹28,000.

Maturity Amount = Principal Amount + Simple Interest = ₹(50,000 + 28,000) = ₹78,000.

Hence, you will receive a maturity amount of ₹78,000 after 8 years of investment in this FD scheme.

2. Compound Interest

Under this method, the amount of interest is calculated on the basis of the principal amount as well as the interest accumulated throughout the tenure. In simpler words, the interest is calculated on a compounded basis, and you earn interest over interest. 

Let’s understand this further by checking out the formula to find out the maturity amount. 

A = P (1+r/n) ^ (n * t)

Here, 

• P = Principal Amount.

• A = Maturity Amount,

• r = Rate of Interest,

• n = Number of times interest is compounded in a year

• t = Number of years

Now, let’s assume you want to invest in another HDFC FD scheme by depositing a sum of ₹1,00,000 for 5 years. This scheme has an applicable interest rate of 7%, paid semi-annually.

So, your Principal Amount (P) = ₹1,00,000, Number of years (t) = 5, Number of Compounds in a year (n) = 2 and Rate of Interest (r) =7%.

By putting in the values in the formula mentioned above, your Maturity Amount (A) = ₹{1,00,000 (1+0.07/2) ^ (2 * 5)} = ₹1,41,059.

Therefore, if you invest in this HDFC FD scheme, you will receive a maturity amount of ₹1,41,059 after 7 years.

Now, you can find the amount of interest by subtracting your deposit money amount from your maturity value.

Compound Interest Earned = Maturity Value - Principal Amount = ₹(1,41,059 - 1,00,000) = ₹41,059.

This means that this FD scheme will provide you with an interest of ₹41,059 over 7 years.
