How do you calculate 3 months simple interest?

Calculating Simple Interest for Three Months

Simple interest is a method of calculating interest that is based on the principal amount (the original amount borrowed) and the annual interest rate, and does not take into account compounding. It is calculated as follows:

Simple Interest = (Principal Amount) * (Annual Interest Rate) * (Time)

Where:

• Simple Interest is the amount of interest accrued over the given time period.
• Principal Amount is the original amount borrowed.
• Annual Interest Rate is the yearly interest rate expressed as a decimal.
• Time is the length of time over which the interest is calculated.

To calculate simple interest for three months, we need to adjust the time period in the formula. Since there are 12 months in a year, three months represent a fraction of 12, which is calculated as 3/12.

Therefore, the formula for calculating three months simple interest becomes:

Simple Interest = (Principal Amount) * (Annual Interest Rate) * (3/12)

Example:

Let’s say you borrow $1,000 at an annual interest rate of 5%. Calculate the simple interest for three months.

Using the formula:

Simple Interest = $1,000 * 0.05 * (3/12)

Simple Interest = $12.50

Therefore, the simple interest accrued over three months is $12.50.
