Decoding FD Interest: Simple vs Compound Returns

Fixed Deposits (FDs) are one of the most popular investment options in India, offering guaranteed returns with low risk. When you invest in an FD, you earn interest based on the deposit amount, tenure, and interest rate. But did you know that the way interest is calculated can significantly impact your returns? Let’s dive into the world of simple vs compound interest to understand how FD interest is calculated and how you can maximise your FD earnings.

Understanding Simple Interest

Simple interest on FD is calculated only on the principal amount you invest. It does not consider any interest earned over time. The formula for simple interest is:

Simple Interest = (P × R × T) / 100

Where:

• P is the principal amount
• R is the interest rate per annum
• T is the tenure of the deposit in years

For example, if you invest ₹1,00,000 in an FD at 6% simple interest for 3 years, the interest earned would be:

(1,00,000 × 6 × 3) / 100 = ₹18,000

At maturity, you will receive your principal of ₹1,00,000 plus the simple interest of ₹18,000, totalling ₹1,18,000.

Exploring Compound Interest

Compound interest on FD, on the other hand, is calculated on both the principal and the interest earned over time. This method allows your money to grow exponentially, as interest is added back to the principal at regular intervals, such as monthly, quarterly, or annually.

The formula for compound interest is:

A = P (1 + r/n)^(n×t)

Where:

• A is the maturity amount
• P is the principal amount
• r is the annual interest rate
• n is the number of times interest is compounded per year
• t is the time the money is invested in years

Let’s say you invest the same ₹1,00,000 at 7% interest, compounded annually for 3 years. Using the Airtel Finance fixed deposit interest calculator, you can easily determine the maturity amount:

A = 1,00,000 (1 + 0.07/1)^(1×3) ≈ ₹1,22,504

With compound interest, you earn an additional ₹4,504 compared to simple interest.

Comparing Simple and Compound Interest

To illustrate the difference, let’s compare the returns on a ₹5,00,000 FD at 7% interest for 5 years:

• Simple Interest: ₹1,75,000
• Compound Interest (Annual): ₹2,01,371

By choosing compound interest, you can earn an extra ₹26,371 on your investment.

Maximising Your FD Returns

To get the most out of your fixed deposit, consider the following tips:

1. Opt for compound interest: As seen above, compound interest can significantly boost your earnings over time.
2. Choose a longer tenure: The power of compounding works best over longer periods. If you don’t need the funds immediately, consider investing for 3-5 years or more.
3. Reinvest the interest: If you don’t require regular payouts, reinvesting the interest can further enhance your returns through compounding.
4. Ladder your FDs: Instead of investing a lump sum in a single FD, spread your investment across multiple FDs with different maturities. This strategy, known as laddering, provides both liquidity and higher average returns.
5. Compare interest rates: Airtel Finance offers competitive FD interest rates for various tenures. Make sure to compare rates across banks and choose the best option for your needs.
