Simple Interest Calculator: How to Calculate Interest on ?7300 for 3 Years at 12%

When dealing with borrowed money, it is crucial to understand how the interest is calculated. In this article, we will explore how to calculate simple interest on ?7300 for three years at a 12% interest rate, using both a straightforward method and the formula for simple interest.

Understanding Simple Interest

Simple interest is a type of interest that is calculated based on the original principal amount. Unlike compound interest, simple interest does not factor in any added interest from previous periods. This makes it a simpler and more straightforward calculation.

Simple Interest Formula

The formula for calculating simple interest is:

I P × N × R / 100

Where:

I is the simple interest P is the principal amount (the initial sum of money) N is the number of years or period of the loan or investment R is the rate of interest per annum (annual interest rate)

Let's break down the calculation step by step using our example.

Calculation Example

Step 1: Identify the Values

Given the following details:

P (Principal Amount) ?7300 N (Number of Years) 3 years R (Rate of Interest per Annum) 12%

Step 2: Apply the Formula

The formula is:

I 7300 × 12 × 3 / 100

Breaking it down further:

First, multiply the principal amount (P) with the rate of interest (R): 7300 × 12 87600 Next, multiply the result by the number of years (N): 87600 × 3 262800 Finally, divide by 100: 262800 / 100 2628

Therefore, the simple interest charged is ?2628.

Alternative Method: Simple Approach

Another way to calculate simple interest is to use the straightforward method, which involves finding the interest for one year and then multiplying it by the number of years.

Interest for one year 12% of 7300 ?876 For three years, the total interest 876 × 3 ?2628

This method is more intuitive and easier to remember, making it a great way to quickly check your work with the formula.

Why Use Simple Interest?

Short-term loans for consumers and businesses Investments in certain financial instruments Government bonds that pay simple interest

Advantages of simple interest include:

Predicable and easy to calculate No need to account for compounded interest Provides a clear understanding of the total cost or benefit
