### What is a Simple Interest?

A = P (1+rt)

Simple interest is a method of calculating intereston a loan or investment. It is called "simple" because it is computedonly on the initial principal amount without taking into account any interestthat may have been accumulated in previous periods.

For Example, suppose you borrow Rs 2,500 from a colleague for nine months, with a simple interest rate of 6%. At the end of the borrowing period, you would repay your colleague a total of Rs 2,650 (Rs 2,500 principal + Rs 150 in interest).

### What is a Simple Interest Calculator?

A Simple Interest Calculator is a financial tool that helps individuals determine the interest earned or paid on a principal amount over a specified period.  It operates on the principle of simplicity, considering only the initial principal, the interest rate, and the time involved. Users input these variables, and the calculator provides the straightforward calculation of interest, aiding in financial planning and decision-making.

### How Does Simple Interest Calculator work?

A = P (1 + rt)

Where:

• P: Principal amount (initial borrowed or invested amount)
• r: Annual interest rate (in decimal form)
• t: Time the money is borrowed or invested for (in years)
• A: represents the Total accumulated Amount (principal + interest)

Interest = A – P

### ‍Example:

Suppose the principal amount is Rs 15,000, the interest rate is 8%, and the time period is four years.

A=15,000×(1+0.08×4)=Rs19,200

So, the total amount after four years would be Rs 19,200. To find the interest earned, subtract the principal:

Interest=A−P=19,200−15,000=Rs4,200

Therefore, the simple interest accrued over the four-year period would be Rs 4,200.
