When looking to grow your investment through a fixed deposit, one of the most important factors that you must consider is the interest rate. The interest rate offered by the FD issuer is generally predetermined and remains constant during the entire tenor.
You can optimise your earnings by comparing the interest receivable on different fixed deposit schemes. There are two formulae that allow you to determine the interest amount for an FD investment: equation, simple interest, and compound interest.
Moreover, you can use the ‘₹3 interest for ₹30,000 per month’ concept to estimate the total interest amount on a fixed deposit.

The ₹3 interest for ₹30,000 per month invested in an FD works in the same way as the ‘₹1 interest’ method. The following table presents different formulae, along with illustrations, on how to calculate your FD interest:

‘₹3 interest for ₹30,000 per month’ Method |
If you receive ₹3 interest per ₹100, the yearly interest rate would be 3 X 12 = 36% |
If you have invested ₹30,000 for monthly payouts at a 3% interest rate, the annual interest rate of the FD would be 36%. Monthly interest = 30,000 X 3/100 = ₹900 |
Simple Interest Method |
I = P X R X T

If you invest ₹30,000 in the FD for a year, the interest earned at the end of the maturity period would be 30,000 X 36/100 X 1 = ₹10,800
Interest amount as monthly payout = 10,800/12 = ₹900 |
Compound Interest Method |
I = [P (1 + r/n)^n X t] – P
Here,
|
Investing ₹30,000 for a year in an FD, compounded annually, the interest amount would be [30,000 X (1+36/100/1)^1*2] - 30,000 = ₹10,800
Monthly interest = 10,800/12 = ₹900 |
The ₹3 interest for ₹30,000 per month you can earn when invested in an FD depends on the formula used for calculation. The interest remains the same under both the methods in the above illustration.
However, the compound interest would be higher than simple interest if you park the funds in the FD for more than a year or if it compounds more than once annually. In conclusion, while you can use these formulae to estimate the interest receivable, you may find the entire process to be complicated.
Moreover, a manual error in calculation can also result in inaccuracies. Hence, it is advisable to use the Bajaj Markets FD interest rate calculator to find how much you can earn in the form of an interest component. It is an online tool that lets you estimate your FD returns quickly and without any hassle.

The formula to determine simple interest for ₹3 interest for ₹30,000 per month in FD is P X R X T.
The initial investment amount, the interest rate offered by the issuer, and the length of the tenor influence your FD earnings.
To calculate compound interest for ₹3 interest for ₹30,000 per month on FD, you must use this formula: I = [P (1 + r/n)^n X t] – P.
The simple interest receivable for such an FD would be ₹32,400.
