‘₹1.5 Interest for ₹1 Lakh’ Method

With ₹1.5 interest on ₹100, the annual interest rate would be 1.5 X 12 = 18%

If you invest ₹1 Lakh at a 1.5% interest rate per month, your annual interest rate would be 18%.


Monthly interest to be received = 1,00,000 X 1.5/100 = ₹1,500

Simple Interest Method

The formula for simple interest is: I = p × r × t

 

Here,

  • I = interest amount

  • P = principal amount

  • R = Annual rate of interest 

  • T = Tenor (in years)

If you invest ₹1 Lakh for a year, the interest earned at the end of the tenor would be,

1,00,000 X 18/100 X 1 = ₹18,000


Monthly interest earned: 18,000/12 = ₹1,500

Compound Interest Method

The formula for compound interest is,

I = [P (1 + r/n)^n X t] – P

 

Here,

  • I = Interest value

  • P = Principal amount

  • r = Interest rate

  • n = Number of compounding periods

  • t = Tenor

On investing ₹1 Lakh for one year, compounded annually, the interest is calculated as,

 [1,00,000 X (1+18/100/1)^1*1] – 1,00,000 = ₹18,000


Monthly interest earned: 18,000/12 = ₹1,500

₹1.5 Interest for a ₹1 Lakh FD Per Month

The interest you can earn with ₹1.5 interest for a ₹1 Lakh FD investment depends on the tenor and the type of FD you choose. For instance, the interest earnings would be higher in a compounding FD than that of an FD with simple interest. 

 

This is because the current interest gets added, or compounded, to the principal amount for the purpose of calculating your next interest. As such, you earn interest even on the accumulated interest. 

 

You can calculate the monthly interest or the total interest using the simple or compound interest formula with the appropriate values. However, manual calculations can be risky as there is a chance of error. Moreover, it can be tedious and time-consuming.


A better alternative to manual calculations is the FD calculator available on Bajaj Markets. This is an online tool that allows you to calculate FD interest amounts quickly and without any hassle.
