Calculating Simple Interest: A Comprehensive Guide

Simple interest is a common method of calculating the interest applied to a loan or investment. It's easy to understand and compute, making it a popular choice for financial calculations. In this article, we'll walk through the process of calculating simple interest using an example problem.

Understanding Simple Interest

Simple interest is calculated using the formula:

SI (P × R × T) / 100

Where:

P is the Principal amount R is the Rate of Interest T is the Time period in years

Example Problem

Let's consider an example where we need to calculate the simple interest for Rs. 1600 at a rate of 15/2% per annum for a period of 2 years and 4 months.

Determine the Variables

The given values are:

Principal (P) Rs. 1600 Rate of Interest (R) 15/2% 7.5% Time (T) 2 years and 4 months 2 years 4/12 years 2 1/3 years 7/3 years

Calculate the Simple Interest

Plugging these values into the formula:

SI (1600 × 7.5 × 7/3) / 100

Let's break down the calculation step-by-step:

First, calculate the product of the principal and the rate of interest: 1600 × 7.5 12000 Next, multiply the result by the time period: 12000 × 7/3 12000 × 2.3333 (approx) ≈ 28000 Finally, divide by 100 to get the simple interest: 28000 / 100 280

Therefore, the simple interest on Rs. 1600 at 15/2% per annum for 2 years and 4 months is Rs. 280.

Conclusion

This step-by-step approach helps in accurately calculating simple interest, which is essential for financial planning and analysis.
