# Simple Interest Calculator in India: Learn How to Use

September 11, 2024

Personal finance is crucial to our life. We need to manage our finances to maintain a decent financial status. Managing personal finance often includes borrowing money. Borrowing money is to meet certain financial needs at that time. But we need to return the borrowed money after a specific time frame. For instance, you can borrow money from banks to pursue higher studies abroad. After completing the course, you can repay the money within the notified time. But there is a third important component called “Interest” we need to consider.

While borrowing capital, the lender will include a monetary charge called interest. Interest is more like compensation for lending money. The money lenders perceive the interest as income. Interest as income has become a business on its own. Both government and private sectors have such financial corporations. Different corporations offer different interest rates. Thus, we need to calculate the interest capital as per the interest percentage. Using the calculated interest, we can select a suitable loan type.

Consider bank A has a 3% per ₹1000 interest rate and bank B has a 5% per ₹10000 interest rate. Hence it is difficult to determine which bank offers low interest. You can do a manual calculation to find out the interest. But humans often make mistakes. We can’t afford mistakes while dealing with money. That’s why we need a simple interest calculator in India to know accurate interest rates. Wondering how to calculate interest using an interest rate calculator? Here is a step-by-step guide to an interest percentage calculator.

## Simple Interest Calculation Formula

People know two interest types: simple and compound. Simple interest involves the money lent. But compound interest involves the money lent and the paid interest on the loan. The banks often use compound interest in rare cases. But simple interest is the more common type of interest applied.
To calculate the simple interest, we use the simple interest formula below:
A = P (1+rt)
To know the total interest amount repaid, subtract the principal from accrued money:
Interest Capital = A – P

### Terms Used to Calculate Simple Interest

In this section, we take a closer look at the terms used in the simple interest formula. Each term will be elaborate to ensure accurate calculation.
Principal (P): It refers to the capital amount lent by the financial corporation. The corporation can be a bank or an individual.
Rate of Interest (r): The percentage of interest expected in return by the lender (in numbers).
Time (t): The notified time intimated by the lender to repay the principal and interest capital (in years).
Accrued Money (A): The borrower’s total money to repay. It comprises both principal and interest capital.

### Example for Calculating Simple Interest

Let’s look at a simple example to calculate simple interest. Consider the principal amount is ₹ 10000.. Let the interest rate be 15%, and the repayment time is 12 years. To calculate the simple interest:
A = P (1+rt)
Here, P = 10000, r = 0.15, and t = 12. So, the simple interest will be
A = 10000 (1+0.15 *12)
A = 10000 (1+ 1.8)
A = 28000.
To calculate the interest capital that needs to be repaid,
Interest= A – P
Interest= 28000 – 10000
Interest= 18000

Step 5: The monthly interest calculator will display the accrued amount and interest.

### Input Parameters Required

While using a simple interest calculator in India, you must enter all the input parameters required by the calculator. Entering an incorrect input parameter will tamper with the results. Here’s detailed information on input parameters to avoid mistakes.

Principal amount: is a crucial input parameter in calculating simple interest. The calculator evaluates the simple interest based on the principle. For example, if you borrow ₹10,000 from the bank, enter P=10000 in the formula box.

Rate of Interest: you need to enter the proper percentage interest rate. Normal numbers are different from percentages. If you loan money at the interest rate of 10%, enter r=10 % in the formula box.
Repayment time: This is the input parameter where people often make mistakes. If you loan the money for 2 years, enter t=2 in the formula box. Select the correct unit (years, months, and days).
Final sample result: As per sample input, you borrow ₹10,000 from the bank at a rate of 10 % for two years. Enter all the parameters in the formula box. The calculator will display the accrued money as ₹12,000 and interest as ₹2,000.
