Fixed deposits are favoured investments for a reason. The interest income is fixed and regular, and, in most cases, higher than the interest you get from savings accounts. However, the interest calculation differs based on monthly, quarterly, bi-annual, and yearly interest payouts.
For investors, a solid understanding of how to calculate the interest receivable is very useful. It allows for easy comparison of returns based on FD tenors, interest rates, and other terms. For monthly interest payouts, you can calculate returns using three methods.
These are the simple interest, compound interest, and equation methods. Each of these formulas can be used to arrive at the same monthly interest payout for the same investment value. However, interest can also be calculated on a quarterly, bi-annual, or annual basis.

‘₹2 Interest for ₹1 Lakh Per Month’ Method |
₹2 interest per month indicates an interest earning of ₹2 on ₹100 invested in an FD. Yearly interest rate: 2 x 12 = 24% |
This 2% return per month lets you calculate ₹2 interest for ₹1 Lakh, as follows: Monthly interest payout = 1,00,000 * 2/100 = ₹2,000 This makes the total interest earnings on an FD of ₹1 Lakh for a year ₹24,000. |
Simple Interest Method |
The formula to calculate simple interest is: (Principal * Rate * Time) / 100 |
Using the same figures from the example above, the yearly interest payout can be calculated using the formula: 1,00,000 * 24/100 * 1 = ₹24,000 Monthly interest earned: 24,000 / 12 = ₹2,000 |
Compound Interest Method |
The formula is as follows: [P*(1 + R)^nt] - P Here, P = Principal amount R = Rate of interest n = Number of periods t = Time period |
In this example, the interest is considered to be compounded once a year. To calculate the ₹2 interest for ₹1 Lakh in an FD, apply the formula to get: [1,00,000 X (1+24/100)^1*1] - 1,00,000 = ₹24,000 Monthly interest payout: 24,000/12 = ₹2,000 |
The calculation of compound interest is more layered, as it takes into account the number of times the interest is compounded. This amount is then added to the initial principal, generating higher interest.
The total interest per month that you can receive from an FD of ₹1 Lakh yielding ₹2 interest per month is ₹2,000, regardless of the calculation method you employ. Using this simple calculation method, you can arrive at the exact value of FD interest you are due to receive each month.
