When choosing a fixed deposit to invest in, one of the most important factors you must consider is the interest rate offered by the issuer. The interest rate is predetermined, and you can use it to calculate how much returns you would earn at the end of the tenor. 


There are two main formulas that allow you to calculate the total interest receivable: simple interest and compound interest. Moreover, you can also use the ‘₹2 interest for ₹20,000 per month’ method to determine the interest receivable at the end of the investment horizon. 

Formula with an Illustration

Just like the ‘₹1 interest’ method, you can use the ‘₹2 interest for ₹20,000’ method to find out your FD returns. In other words, if you earn ₹2 interest for ₹20,000 principal amount per month, you can use this method to find the total interest receivable:


Here is the table showcasing different formulas and illustrations to find your FD returns if the initial investment that you make is ₹20,000:     

Calculation Method



‘₹2 Interest for ₹20,000 Per Month’ Method

With ₹2 interest on ₹100, the annual interest rate would be 2 X 12 = 24%

On investing ₹20,000 for monthly payouts at a 2% interest rate, your annual interest rate would be 24%.

Monthly interest receivable = 20,000 X 2/100 = ₹400

Simple Interest Method

I = p × r × t



  • I = Interest 

  • p = Principal amount 

  • r = Interest rate

  • t = Investment period 

Assume you invest the same amount for a tenor of two years. The interest earned in two years would be

10,000 X 24/100 X 2 = ₹4,800


Monthly interest = 4,800/12 = ₹400  

Compound Interest Method

I = [P (1 + r/n)^n X t] – P



  • I = Value of interest 

  • r = Interest rate (in decimal format)

  • n = Number of times the interest gets compounded

  • t = Tenor

If you invest ₹20,000 for the same length of tenor, compounding annually, the interest amount would be [20,000 X (1+24/100/1)^1*1] - 20,000 = ₹4,800


Monthly interest = 4,800/12 = ₹400  

₹2 Interest for ₹20,000 Per Month

So, if you invest ₹20,000 as an initial investment in an FD providing ₹2 interest for two years, you can earn a monthly interest of ₹400. Alternatively, if you choose a compounding FD, your interest may be higher if it is compounded more than once yearly.


However, if you calculate FD interest manually, you may find the process complex and cumbersome. In addition to this, even a small manual error can cause huge variations in the end result. 

Hence, it is advisable to use Bajaj Markets’s FD calculator to determine the amount of interest receivable. This online tool is not just quick but also easy to use. All you have to do is enter the principal amount, interest rate, and the tenor to determine your FD returns.
