## What Is the Formula to Calculate Simple Interest?

Simple interest calculation follows the formula discussed below,

A = P (1+rt)

The variables used in this formula are as follows,

P = Principal Amount

t = Number of years

r = Rate of interest

A = Total accrued amount (both interest and principal)

The formula to calculate interest is as follows,

Interest = A – P

As individuals know the simple interest formula, let’s see the way it works/show results in a calculator.

Online simple interest calculator eases the calculation process. Here, individuals have to enter details in the respective fields or adjust sliders to set the principal amount.  Individuals have to enter data in three areas, namely principal, interest rate, time.

Let’s understand this calculation more clearly with the help of an example given below!

Suppose Mr. Rajan has invested an amount of ₹ 10,000 for 6 years at an interest rate of 10%.

The interest and amount he will accrue after 2 years will be,

 Input Value Principal ₹ 10,000 Interest Rate 10% Tenure 6 years

Once individuals enter details in the required fields, this simple interest calculator will display the following result.

 Output Values Total Amount A = 10,000 (1+0.1*6) ₹ 16,000 Interest Amount A – P = 16000 – 10000 ₹ 6,000
