Simple Interest Calculator – Make Smarter Financial Decisions | GoodTechReview
When it comes to personal finance, understanding how interest works is fundamental. Whether you’re a student, investor, business owner, or simply someone managing debt or savings, knowing how interest accumulates is essential. This is where a simple interest calculator becomes an incredibly useful tool.
At GoodTechReview, we provide a fast, intuitive, and mobile-friendly Simple Interest Calculator that lets you determine how much interest you’ll earn or owe based on the principal, interest rate, and time.
🔍 What is simple interest?
Simple interest is a method of calculating interest that is only applied to the initial amount of money (the principal). Unlike compound interest, which adds interest to accumulated interest, simple interest remains straightforward and easy to understand.
The formula used is
Simple Interest = (Principal × Rate × Time) ÷ 100
Where:
- Principal is the initial amount
- Rate is the annual interest rate (in %)
- Time is the period in years
A simple interest calculator makes this calculation instant and error-free, giving you results in just a few clicks.
