What is Simple Interest?
Simple interest is a method used to determine the amount of interest accrued on a principal sum over a specified period at a fixed rate. In simple interest, the principal remains constant, making it a straightforward approach for interest calculation.
Simple interest offers a straightforward method for understanding the cost of borrowing. It calculates the interest rate based on the initial principal amount, which remains constant as long as payments are made punctually. There's no compounding interest or consideration of interest accruing on a growing balance.
This implies that, for loan terms exceeding one year, you'll consistently incur lower interest charges with a simple interest loan compared to a compound interest loan. Many debt agreements necessitate a more intricate interest calculation than simple interest.
How do I Calculate a Simple Interest Rate?
To calculate the simple interest rate, you need to subtract the principal amount from the final amount, divide the result by the principal amount, and then multiply by 100. Let's illustrate this process with an example:
Suppose Sumit borrows ₹1,00,000 from a bank for a period of 1 year at an annual interest rate of 10%. Here's how sumit's loan account would appear at the end of the year:
Principal amount (P): ₹1,00,000
Annual interest rate (R): 10%
Time period (T): 1 year
Calculation of simple interest: (P x R x T)/100 = (1,00,000 * 10 * 1)/100 = ₹10,000
Therefore, Sumit has to repay the principal amount plus interest at the end of year 1, which equals ₹1,00,000 + ₹ 10,000 = ₹1,10,000.
Moreover, to determine the interest rate, the calculation proceeds as follows:
Interest rate % = [(₹1,10,000 – ₹1,00,000)/₹1,00,000] * 100 = 10%
How can I Compute Monthly Simple Interest?
The calculation of simple interest is straightforward using the formula provided below:
Simple interest = (Principal x Rate x Time)/100
How does Simple Interest Calculator Works? To illustrate this clearly, let's apply the formula to the following example:
Suppose you invest ₹5,00,000 in a fixed deposit account for 5 years, with an FD rate of 10%. Using the SI formula, the interest earned on your deposit would be calculated as follows:
SI = 5,00,000 x 10 x 5 ÷ 100 = ₹2,50,000
Total Amount at the end of 5 years = ₹5,00,000 + ₹2,50,000 = ₹7,50,000.
Consequently, you would receive an additional interest of ₹2.50 Lakh at the end of the 5-year maturity period.
Furthermore, the maturity amount of the Fixed Deposit would be ₹7.50 Lakh.
Which is Preferable, Simple or Compound Interest?
Simple interest, in contrast to compound interest, offers easier computation and comprehension. In scenarios involving temporary loans or those with non-compounding interest, the focus remains solely on the interest accumulated on the outstanding principal balance. For instance, mortgages and most car loans adhere to simple interest accrual without compounding.
On the other hand, when it pertains to investments, compound interest proves advantageous as it facilitates accelerated growth of funds compared to accounts with a simple interest structure. Compound interest becomes significant when computing the annual percentage yield, representing either the annual rate of return or the annual borrowing cost.
