Simple Interest Breakdown
What is Simple Interest?
Simple Interest (SI) is calculated only on the original principal amount, and does not compound over time. It is the most straightforward form of interest and is commonly used in short-term loans, fixed deposits under one year, car loans, and consumer finance in India.
Simple Interest Formula
The formula is: SI = (P × R × T) / 100, where P is the principal amount, R is the annual interest rate (%), and T is the time in years. The total amount payable or receivable is A = P + SI.
Simple Interest vs Compound Interest
Unlike compound interest, simple interest does not earn interest on accumulated interest. This makes it less powerful for wealth creation but easier to understand. For periods greater than one year, compound interest will always yield a higher return than simple interest at the same rate.
Where is Simple Interest Used in India?
Simple interest is commonly used in short-term personal loans, vehicle loans, some microfinance products, post office schemes of short tenure, and for calculating late payment charges on utility bills and credit cards.
