Simple Interest: A Non-Compounding Approach to Calculating Interest

Simple interest is a strghtforward method used in calculating the interest accrued on a principal amount without the compounding effect. In contrast to compounding, where interest earned during one period is added to the principal sum for subsequent periods, simple interest focuses only on the original principal.

Formula for Simple Interest

The formula for calculating simple interest is:

I = P times R times T

where I represents the interest amount, P stands for the principal the initial amount of money, R is the annual interest rate in decimal form, and T denotes the time period in years.

Example #1: Mr. Albertson’s Certificate of Deposit

Let's consider with Mr. Albertson who plans to invest $10,000 at a 5 annual simple interest rate for three months.

I = $10,000 times 0.05 times frac312

Here, P = $10,000, R = 5 = 0.05 converted from percentage to decimal form, and T = frac312 year since three months is a quarter of a year.

I = $125

Example #2: Sara’s Loan

Now let's calculate the total interest expense on a five-year loan with principal $7,000 at 3 annual simple interest rate.

I = $7,000 times 0.03 times 5

Here P = $7,000, R = 3 = 0.03 and T = 5 years.

I = $1,050

Real-life Applications of Simple Interest

Simple interest finds application in various real-world financial scenarios:

• Bonds: Bond investors receive regular coupon payments that are based on the simple interest calculation method. These payments do not accrue additional interest.

• Mortgages: Most mortgages are structured under a simple interest basis, meaning they calculate interest due only on the principal amount borrowed without compounding effects.
