Or to find it manually, you can use the formula listed below: $simple\;{\mathop{\rm interset}} = si = \frac{{(P\;*\;R\;*\;T)}}{{100}}$ Where, P = the principal or the actual amount R = Rate of interest T = Period of loan (calculated in years) ### Example 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 = ?

Solution

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:

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