How to Calculate Simple Interest

What is Simple Interest?

A simple interest calculator computes interest using I = PRT (Principal × Rate × Time), without compounding. Simple interest is used in most short-term loans, car loans, and some savings bonds. It is predictable but lower-earning than compound interest for savings and higher-cost for long-term loans.
