Simple Interest Calculator

If you want to determine or compute the interest paid on the actual loan amount, you can use our simple interest calculator.

In finance, simple interest is defined as a method used to compute the rate of return (in terms of profit) on the amount of the actual amount of the loan. In most financial sectors like banking, finance, and automobiles, simple interest is used while giving a loan to the consumer. In other words, simple interest is defined as an interest paid or calculated on the actual price of a loan or the deposited amount of money to banks.


Formula of Simple Interest Calculator

To instantly find out the perimeter of a triangle, you can jump to our calculator. Or to find it manually, you can use the formula listed below:

\[simple\;{\mathop{\rm interset}} = si = \frac{{(P\;*\;R\;*\;T)}}{{100}}\]


P = the principal or the actual amount

R = Rate of interest

T = Period of loan (calculated in years)


For a more precise understanding of the concept, let us solve an example below:

Suppose Dan takes a bank loan of $10,000 for a year, whereas the annual interest rate on the loan is10%, then find out the amount of interest Dan has to pay at the year's end.

Given data

The principal or the actual amount = P = $10,000
Rate of interest = R = 10%
Period of loan = T = 1 year

To Find

Simple interest = ?


To find out the perimeter of a triangle, we will use the formula listed below:

\[simple\;{\mathop{\rm interset}} = si = \frac{{(P\;*\;R\;*\;T)}}{{100}}\]

Putting values in the formula:

\[simple\;{\mathop{\rm interset}} = si = \frac{{(10000\;*\;10\;*\;1)}}{{100}}=$1000\]
