Preguntas frecuentes
What is simple interest?
Simple interest is calculated only on the original principal using the formula I = P x R x T. It does not compound - meaning interest does not earn additional interest.
When is simple interest used?
Simple interest commonly applies to short-term loans, some car loans, and certain savings instruments. It is less common than compound interest for long-term investments.
Can I enter the time in months?
Yes. The template supports days, months, and years with automatic conversion between them. Enter whichever unit is most convenient.
How does this compare to compound interest?
Simple interest always produces a lower return than compound interest over the same period because it does not earn interest on accumulated interest.
