Why do so many Indians love FD deposits? A study by Kuvera threw up some rather interesting insights. Almost 44% of 1.6 million respondents talked of how they went for FDs whenever they wished to save money for specific purposes safely within three years. 23% also chose these investment options to park their emergency funds in order to combat inflation, while one out of ten invested to gain safety from volatility in the market. 12% also preferred these investments since they were not just familiar, but also simpler than many other options. All that is fine, but how are the interest rates calculated on FDs? Let us find out more in this article.

Importance of Interest Rates

One of the reasons that accounts for the huge popularity of fixed deposits is the interest rate provided for them. The higher the interest rate, the more you earn on your investment. Hence, you must know how interest rates are computed on fixed deposits. It will help you have a better understanding while finding an investment alternative.

Understanding Interest Rates on Fixed Deposits

Interest rate is the amount of money a bank or any financial institution pays you for depositing your money with them. It is generally calculated as a percent of the amount deposited. Fixed deposits offer interest based on the amount deposited, the period of investment and the rate of interest offered by the bank. The rate of interest can be calculated in two ways - simple interest and compound interest. Various factors that impact the interest rates in fixed deposits include inflation, economic conditions, RBI policies, and competition. Depending on all these factors, your interest rate can vary from 4.5% to 9.00%, as offered by Unity Small Finance Bank. Moreover, most banks offer special rates of FD interest for senior citizens, such as an additional interest rate of 0.5%.

Different Types of Fixed Deposit Interest Rates

1. Simple Interest

Simple interest is calculated on the principal amount deposited for the entire period of investment. It is a straightforward method of calculating interest and is usually offered on shorter-term fixed deposits.


2. Compound Interest

Compound interest is calculated on the principal amount deposited as well as the interest earned during the previous period. It is a more complex method of calculating interest, but offers higher returns than simple interest. Compound interest is usually offered on longer-term fixed deposits.

How to Calculate Interest on Fixed Deposits

Using the Simple Interest Formula

The simple interest formula is as follows: Interest = (Principal x Rate x Time)/100. You can use this formula to calculate the interest earned on a fixed deposit using simple interest. Here's an example of such. For simple Interest calculation with a principal amount of 1,00,000, let's assume an interest rate of 5% per annum for a period of 2 years. Simple Interest = (Principal * Rate * Time)/100 = (1,00,000 * 5 * 2)/100 = 10,000 Therefore, the Simple Interest for a principal amount of 1,00,000 at an interest rate of 5% per annum for a period of 2 years is 10,000.

Using the Compound Interest Formula

The compound interest formula is: A = P x (1 + r/n)^(nt). A is the total amount earned, P is the principal amount, r is the interest rate, n is the number of times interest is compounded per year, and t is the number of years. For an example of compound Interest calculation with a principal amount of 1,00,000, let's assume an interest rate of 10% per annum, compounded annually for a period of 3 years. In this case, n = 1 (as the interest is compounded annually) Compound Interest = 1,00,000(1 + 0.1/1)^(1*3) - 1,00,000 = 1,00,000(1.1)^3 - 1,00,000 = 1,33,100 - 1,00,000 = 33,100 Therefore, the Compound Interest for a principal amount of 1,00,000 at an interest rate of 10% per annum, compounded annually for a period of 3 years is 33,100.

Using an online calculator

There are several online calculators available that can help you calculate the interest earned on an FD Deposit. All you need to do is enter the principal amount, the interest rate, and the period of investment.
