What Is Simple Interest?
Simple interest is the basic method of calculating interest on a principal amount over a fixed period of time. Unlike compound interest, simple interest does not add interest to the principal during the calculation period.
The interest is calculated using this formula:
Simple Interest = (Principal × Rate × Time) ÷ 100
Where:
- Principal = Initial amount of money invested or borrowed
- Rate = Annual interest rate (%)
- Time = Duration in years
Once the interest is calculated, the total amount becomes:
Total Amount = Principal + Simple Interest
The S & P Calculator automates this entire process, saving time and eliminating calculation errors.
