Introduction

Interest rates are the price you pay to borrow money. They represent the cost of borrowing and the reward for lending. Understanding how they work is crucial for making informed financial decisions.

Whether you're taking a loan, saving money, or investing, interest rates play a significant role in your financial outcomes.

What is Interest?

Interest is the fee charged by lenders for the privilege of borrowing money. It's expressed as a percentage of the principal amount borrowed.

Simple vs Compound Interest
