Let’s talk returns

If you are investing in Fixed Deposits, you must remember that the returns will not be exponential. A Fixed Deposit gives you lower returns than, for instance, investments in ELSS Mutual Funds. On the bright side though, Fixed Deposits (FDs) are one of the safest investment options around even though the taxes can be a bit on the higher side.

What is the present interest rate on Fixed Deposits?

At present, the interest rate offered on bank Fixed Deposits is between 5% – 7.5% for regular depositors and an additional 0.5% for senior citizens. Note that company deposits might provide higher returns than bank deposits.

Some banks may offer special interest rates on Fixed Deposits. These are usually for unusual tenures such as 555, 1001 days etc. It always helps to look around for the best rates offered.

Wondering how the interest on your FD is calculated? Let’s begin with a little lesson on simple and compound interest.

Simple Interest Simplified

Simple interest is calculated on the initial Fixed Deposit amount only. How is simple interest calculated?

Let’s give you an example.

FD amount: Rs. 1,00,000
FD tenure: 3 years
Interest rate: 10% p.a.

The math is very simple

Year 1: Rs. 1,00,000 x 10% = Rs. 10,000
Year 2: Same thing…Rs. 1,00,000 x 10% = Rs. 10,000
Year 3: Yes, again! Rs. 1,00,000 x 10% = Rs. 10,000

Total interest earned in 3 years: Rs. 30,000

Ta da! Maturity amount: Rs. 1,00,000 + Rs. 30,000 = Rs. 1,30,000

Decoding Compound Interest

Compound interest is much like interest on interest. Interest is calculated on the principal and the interest earned on the principal.

Getting down to the numbers

Year 1: Rs. 1,00,000 x 10% = Rs. 10,000 (Principal + Interest = Rs.1,10,000)
Year 2: Rs. 1,10,000 x 10% = Rs. 11,000 (Principal + Interest = Rs.1,11,000)
Year 3: Rs. 1,11,000 x 10% = Rs. 11,100.

Total interest earned in 3 years: Rs. 32,100.

Maturity value on payout after 3 years: Rs. 1,32,100, which is higher than what you would have got if it was simple interest.

You must understand that this concept is explained in a simple manner here, but is much more complicated when you include how often the interest is going to compound (that is, how often is interest on interest going to be calculated). Compounding of interest can happen annually, semi-annually, quarterly or monthly. Banks usually calculate interest on a quarterly basis.
