When you invest your funds in a fixed deposit, the earnings you gain from it are your interest income. Depending on the amount you invest, the chosen tenor and the FD interest rate, your earnings vary.
The cardinal rule is that the longer you stay invested, the higher your earnings. So, comparing FD rates from different issuers is essential as that helps you generate higher potential returns.
For instance, if you want to earn ₹5 interest for a ₹1 Lakh FD, you may do so by choosing the right issuer. All you need to do is calculate your interest earnings using simple interest or compound interest formula.
Read on to know more about how you can calculate ₹5 interest per month on a deposit of ₹1 Lakh.
Consider a hypothetical example to know how these formulae work. Here, the ₹5 interest for a ₹1 Lakh FD is calculated via non-cumulative mode. In a non-cumulative FD, you can earn returns on a monthly, quarterly, half-yearly or yearly basis.
Hence, your earnings are not reinvested, unlike in a cumulative FD, where the power of compounding comes into play. See the table below to understand the calculations using different methods.

‘₹5 interest for ₹1 Lakh per month’ Method |
Assuming you plan to earn ₹5 interest per ₹100, the annual interest rate can be roughly translated to 5 X 12 = 60%. |
For a ₹1 Lakh FD, earning monthly interest payouts at ₹5 interest, your approximate interest rate will be 60%. Monthly interest: 1,00,000 x 5/100 = ₹5,000 |
Simple Interest Method |
The formula is as follows: If you are considering one month, then T = 1/12 |
Assume you have invested ₹1 Lakh for a period of 1 year. The interest you earn in a year will be as follows: SI = 1,00,000 X 60/100 X 1 = ₹60,000 Monthly interest: 60,000/12 = ₹5,000 |
Compound Interest Method |
Compound Interest = [P (1 + r/n)nt] – P Here, P = Principal amount r = Interest rate n = Number of times the interest gets compounded t = Tenor |
Assume you have invested ₹1 Lakh for a year, with the interest being compounded once annually. Interest amount: [1,00,000 X (1+60/100*1)^1*1] - 1,00,000 = ₹60,000 Monthly interest: ₹60,000/12 = ₹5,000 |

The total monthly interest you can earn on a ₹1 Lakh FD will be approximately ₹5,000. This is just an approximate amount and may vary if the FD interest is compounded more than once yearly. When this happens, your monthly payout and total interest calculated may vary.
Hence, consider these factors when calculating ₹5 interest for a ₹1 Lakh FD. You can choose any suitable method to compute your interest earnings.
That said, calculating manually can be prone to errors and is a time-consuming process. As these methods are complex, comparing various FD rates can also become quite cumbersome.
To avoid this, you can use an FD interest rate calculator to help you zero in on the best plan. Access the calculator on Bajaj Markets and estimate the total interest earned within seconds.
