Understanding the Basics of Interest Calculation

When it comes to loans, understanding how interest is calculated is crucial. In this article, we will delve into the world of interest calculation and provide a step-by-step guide on how to find the interest paid at the end of one year on a loan of Rs. 600 at 8% per annum.

What is Interest?

Interest is the amount charged by a lender for borrowing money. It is usually expressed as a percentage of the principal amount borrowed. In the case of a loan, interest is calculated on the outstanding balance of the loan.

Key Components of Interest Calculation

To calculate interest, we need to know the following key components:

Principal Amount (P): The initial amount borrowed, which in this case is Rs. 600.
Rate of Interest (R): The percentage at which interest is charged, which is 8% per annum in this case.
Time Period (T): The duration for which the loan is taken, which is 1 year in this case.

Calculating Simple Interest

Simple interest is calculated using the formula:

SI = (P × R × T) / 100

Where:

SI is the simple interest
P is the principal amount
R is the rate of interest
T is the time period

Plugging in the Values

Now that we have the formula, let's plug in the values:

P = Rs. 600
R = 8%
T = 1 year

SI = (600 × 8 × 1) / 100 SI = 48

Therefore, the simple interest paid at the end of one year on a loan of Rs. 600 at 8% per annum is Rs. 48.

Calculating Compound Interest

Compound interest is calculated using the formula:

CI = P × (1 + R/100)^T - P

Where:

CI is the compound interest
P is the principal amount
R is the rate of interest
T is the time period

Plugging in the Values

Now that we have the formula, let's plug in the values:

P = Rs. 600
R = 8%
T = 1 year

CI = 600 × (1 + 8/100)^1 - 600 CI = 600 × (1.08) - 600 CI = 648 - 600 CI = 48

Therefore, the compound interest paid at the end of one year on a loan of Rs. 600 at 8% per annum is also Rs. 48.

Conclusion

In conclusion, calculating interest on a loan is a straightforward process that involves understanding the key components of interest calculation, including the principal amount, rate of interest, and time period. By using the simple interest formula or the compound interest formula, we can easily calculate the interest paid at the end of one year on a loan of Rs. 600 at 8% per annum.
