Exploring the benefits of the FD Interest calculator
Fixed Deposits (FDs) have long been a reliable investment avenue for individuals seeking a secure and steady return rate on their savings. It is the type of investment, wherein you deposit a sum of money for a specific tenure and earn interest at a predetermined rate. The returns you earn are impacted by the amount invested, the applicable interest rate and your chosen tenure. While this is the basic gist of how FDs work, if you wish to navigate how FD interest is calculated, this article is going to help you.
How FD Interest Is Calculated
Banks employ a simple interest calculation method to determine how FD interest is calculated. The formula used for calculating interest is:
A= P(1+r/n)^n*t
Wherein:
‘A’ is the fixed deposit maturity amount
‘P’ is the amount you invest in the FD
‘r’ is the applicable FD interest rate
‘n’ is the number of times interest on an FD is calculated. ‘N’ can equal to ‘1’ for yearly calculations, ‘2’ for half-yearly calculation, ‘4’ for quarterly calculation and ‘12’ for monthly calculation.
‘t’ stands for the tenure of the fixed deposit
Does Fixed Deposit Give Compound Interest?
Banks typically follow a monthly and quarterly compounding frequency for interest calculation on Fixed Deposits. This means that the interest earned during each month or quarter is added to the principal investment amount, and the following interest calculations are based on this amount. Here’s an example to help understand this concept:
Let’s assume that you have invested ₹1,00,000 in a Fixed Deposit with an annual interest rate of 6%, compounded quarterly. After the first quarter, the interest earned (₹1,500) is added to the principal amount, making it ₹1,01,500. The interest for the second quarter is then calculated based on this revised principal, which is higher.
As is evident, this yields to higher returns. Compounding contributes significantly to the growth of your investment over time, compared to simple interest, making Fixed Deposits an attractive option if you are looking for a predictable and stable investment avenue. By choosing a bank offering FDs with monthly and quarterly compounding benefits, you can strike a balance that enhances your investment through compound interest, while ensuring liquidity.
How to Calculate Interest on Fixed Deposit Manually
Most financial institutions offering Fixed Deposit products typically provide FD interest rate calculators that automatically calculate the estimated sums you can get on your investment. You can click here to access the HDFC Bank FD Interest Calculator. However, if you wish to calculate the FD interest rate manually, here are the steps to follow:
Gather Information:
a. Principal amount (P)
b. Annual interest rate (R)
c. Tenure in years (T)Divide the annual interest rate by 4 to get the quarterly rate. Quarterly Rate (QR)=R/4
Calculate Quarterly Interest: Quarterly Interest (QI)=100P×QR×T
After each quarter, add the quarterly interest to the principal: Updated Principal = Previous Principal + QI
Continue the process for each quarter until the maturity period is complete.Sum up the quarterly interest amounts to find the total interest earned.
In case of premature withdrawal, you must adjust the interest calculation based on the number of days the deposit was held.
With these steps, you can manually calculate the interest earnings on your FDs for quarterly payouts. However, when it comes to compound interest, manual calculations can often be error-filled, since the principal amount changes each quarter. So, it is best to use FD interest calculators.
