Common mistakes people make while calculating FD returns

Quick Summary

Although fixed deposits are known for their predictable and assured returns, many investors, while planning their fixed deposits tend to miscalculate and make errors in their actual predicted earnings, because they ignore factors like compounding frequency, taxes, tenure of the FD, and other payout options. Before investing in an FD, it is important for you to understand how the FD returns are calculated so you can make better and informed decisions on your finances and be aware of all the expected returns, rather than having unrealistic expectations.

Introduction

Fixed deposits tend to be investors’ go to choice because of their simple, assured and reliable returns. Due to this, investors tend to rush into the process, which leads to miscalculation of the FD’s maturity value. Calculating the maturity value is not just multiplying the interest rate with the amount invested. FD returns are usually calculated using the compound interest concept, where interest is added periodically to the invested amount based on the agreed upon tenure and the compounding frequency. Once you have understood the basic calculations of FD returns, you will be able to set realistic expectations by avoiding common planning mistakes. 

1. Confusion between Simple Interest and Compound Interest

The most basic mistake that most investors make is to assume that fixed deposit returns are calculated using Simple interest. But in reality, most of the Fixed Deposits follow compound interest, where the interests that are earned are added back to your invested amount periodically, depending on the agreed upon tenure. The frequency of compounding directly affects your final returns, which makes your long-term FDs more rewarding. 

1. Ignoring compounding frequency

Different FDs have different agreed upon terms about their compounding frequencies and overall tenure. The fixed deposit interests can be compounded either quarterly, half-yearly, or annually, depending upon your agreed upon terms. Although your interest rates might remain same irrespective of the compounding period, different intervals can produce different maturity values. This is a very important factor that investors tend to overlook.

1. Ignoring Taxes on FD returns

The fixed deposit interest rates are also eligible for taxes. What most investors do is calculate their fixed deposit returns without factoring in these tax deductions for the interest rates. Because of ignoring these tax deductions, investors usually set higher expectations for the maturity value. It is always wise to calculate your fixed deposit returns while considering the tax on the interest rates. Evaluating the post-tax FD returns helps you gain a more realistic insight on your earnings.

1. Assuming higher interest rate always means higher returns

Just like the concept of “high risk, high return”, people tend to assume the same relationship of “higher interest, higher returns” for Fixed Deposits. Just by having higher interest rates, you cannot guarantee higher returns. Fixed deposit returns are a result of multiple factors like the overall tenure length, compounding method or compounding frequency, and factors like payout options are responsible for your final earnings. If your fixed deposit has a short tenure with a high interest rate, it can also generate comparatively lower returns when compared to FDs with longer tenures but lower interest rates, which result in higher earnings.

1. Not using an FD calculator

Investors with years of experience tend to trust manual calculations of returns rather than using online FD calculators. Manual calculations of FD returns can result in errors. FD calculators help in simplifying the entire calculation process by simply considering all the required data including overall tenure, interest rates, compounding frequency or compounding method and payout option. Use of an FD calculator can decrease chances of unrealistic planning.

1. Overlooking interest payout options

Almost all FDs offer either cumulative or non-cumulative payout options. When it comes to cumulative FDs, the interests are all compounded until the maturity of the deposit and the investor receives the lump sum amount altogether. On the other hand, non-cumulative FDs provide the investors with regular, periodic income payouts. Investors should consider the option they select, while calculating their FD maturity value.

Conclusion

Although fixed deposits remain to be a reliable option, it is important that you accurately calculate your FD return value since it is important for thorough financial planning and helps you be aware of your future incomes. For you to be able to accurately calculate your FD returns, you must first understand your FD compounding, taxes, interest rate and payout structure, to make sure you do not make calculation mistakes and make smarter investment decisions.
