What is Simple Interest?
Simple interest is a method of calculating interest where the interest amount is determined based on the original principal amount, the interest rate, and the time period. Unlike compound interest, which calculates interest on the accumulated amount, simple interest remains constant over time. This makes it easier to predict and manage, especially for short-term loans or investments.
The Simple Interest Formula
The formula to calculate simple interest is:
Simple Interest (SI) = Principal (P) × Rate (R) × Time (T)
Where:
- Principal (P): The initial amount of money borrowed or invested.
- Rate (R): The annual interest rate (in decimal form).
- Time (T): The time period for which the money is borrowed or invested, typically in years.
