Learn how interest rates work, how they affect your loans, and how to make them work in your favor.
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
Simple Interest
Calculated only on the principal amount. Formula: Interest = Principal × Rate × Time
Compound Interest
Interest on interest. Much more expensive over time. Most loans use compound interest.
Types of Interest Rates
Fixed Rate
Stays the same throughout the loan term. Provides predictability and protection against rate increases.
Variable Rate
Changes with market conditions. Can be lower initially but carries risk of increases.
Prime Rate
The rate banks charge their best customers. Other rates are often calculated as prime + margin.
APR vs Interest Rate
APR includes fees and represents true cost. Interest rate is just the borrowing cost.
