Interest calculator

Interest refers to the amount charged by a lender to a borrower for any form of debt given, generally expressed as a percentage of the principal. It is also known as the cost of borrowing money and can be classified into two:-

Simple Interest

It is calculated on the principal amount of the loan.

A = P (1 + rt)   or Simple interest = P*r*t


  • A = Final amount (P + I)
  • P = Initial Principal Amount
  • r = Annual Interest Rate
  • t = Time Period in years
  • n= Number of time periods

Compound Interest

It is calculated not just on the basis of the principal amount but also on the accumulated interest of previous periods. It is important to note that the compound interest amount is not the same for all years since the accumulated interest of previous periods is also taken into consideration.

 A=P (1+ r/n) nt
