What is Simple Interest (Byaj)?
Simple Interest (also called Byaj or Saadha Vyaj in Hindi/Gujarati) is the most straightforward method of calculating interest on a loan or deposit. It is computed only on the original principal — not on accumulated interest — making it easy to understand and verify. The formula is: Interest = (Principal × Rate × Time) / 100.
