## Simple Interest Definition in Python

Simple interest is calculated on the loan principal or the initial deposit in a savings account. Because simple interest does not compound, a creditor will only pay interest on the principal amount, and a borrower will never have to pay additional interest on the previously accrued interest.

## Rate of Interest Definition in Python

An interest rate indicates how much it costs to borrow money or how much it pays to save money. If you’re a borrower, the interest rate is the fee you pay for borrowing money, expressed as a percentage of the loan’s total amount. An interest rate is a percentage that represents the rate of growth of a sum of money over time.

print('Principal Amount is', p)
print('Time Period', t)
print('Rate of Interest',r)
si = (p * t * r)/100
print('Simple Interest', si)
return si
si_in(8, 6, 8)
``````

Output:

Principal Amount is 8

Time Period 6

Rate of Interest 8

Simple Interest 3.84
