What is FD?

FD full for in Fixed Deposit, also known as Term Deposit. FD can be booked in any nationalized or private banks or in post office in India. The main goal of booking FD should be to use the invested amount in some future buying.

For example, you have enough amount to buy a new smartphone with a budget of Rs. 10,000, but you can wait for the next 1 year to check if you get a good deal within your budget with upcoming new smartphones. So you can book an FD for 1 year, post which, you can use the fund to buy a new smartphone of your choice. And this is how, you should link your FD investment to your goals.

How FD Calculator works?

FD Calculator helps you to know how much interest you can earn if you book a FD with specific amount, with interest rate and tenure provided to the calculator. This will help you plan your investments for goals accordingly.

There are 2 types of FD:

  • Cumulative Fixed Deposits: A type of FD that helps you accumulate interest amounts that you gain every quarter. This interest amount helps you earn more interest over long run which is known as Compounding. Compounding in FD usually happens on quarterly basis, which means, your interest calculated every month will be added to your balance every quarter. This increase in balance will help you earn more interest in upcoming quarters and that is why cumulative Fixed Deposits must be preferred.
  • Non Cumulative Fixed Deposits: In this type of FD you get regular payouts may be quarterly or half yearly. This payouts are usually the interest amounts you gain over a quarter of half year. Instead of adding this interest to your balance amount, it is paid out to you which you can treat as a bonuses on regular intervals.

Cumulative Fixed Deposits earn higher interest amounts compared to non cumulative fixed deposits.

The above calculator helps you calculate interest of cumulative fixed deposits.

How to Calculate FD Interest?

Let us take an example of how to calculate Fixed Deposit interest.

For example, if you deposit Rs. 5000 in cumulative Fixed Deposit with 4.5% annual interest rate for 1 year, below are the steps to calculate FD interest:

  1. Calculate monthly interest rate from annual interest rate – 4.5 / 12 = 0.375%. This is the monthly interest rate in our example
  2. Now use monthly interest rate to calculate monthly interest you’ll get using formula – monthly interest rate * amount / 100 = 0.375% * Rs. 5000 / 100 = Rs. 18.75
  3. Since we are considering quarterly compounding, we have to calculate 3 months interest by multiplying one month interest with 3 = Rs. 18.75 * 3 = Rs. 56.25 (3 months interest on Rs. 5000)
  4. Now this interest is added to you balance amount of Rs. 5000, which now becomes Rs. 5056.25
  5. Repeat steps 2-4 using updated balance amounts.

Below is the screenshot showing total interest earned in our example:

As seen above, we get total interest of approx. Rs. 229 and a total maturity amount of approx. Rs. 5229 based on above example.

Watch above video to know how quarterly compounding is done in FD and how total interest is calculated.

After FD maturity, you have 3 options:

  • Take Maturity (total) amount in your Savings account
  • Renew FD (Principal amount only)
  • Renew FD (Principal + Interest amounts)

So it depends on you after FD maturity whether you want to renew the amounts for some more time.

How much you will get on Rs. 1 Lakh FD?

Based on the calculator, for FD of amount = Rs. 1 Lakh, interest rate = 4.5% and tenure = 1 Year, you’ll get total interest = Rs. 4577 and maturity amount = Rs. 1,04,577
