What is interest rate and how does it work?

Interest Rate Meaning

If you have ever applied for a loan or a credit card, you have likely heard the term interest rate thrown around. But what exactly is an interest rate, and how does it work? Interest rates play a significant role in our financial lives, so it’s essential to understand how they impact us. In this post, we will break down the subject of interest rates and provide you with an understanding of how they work.

What are interest rates?

An interest rate is a percentage that is charged on the amount of money borrowed or deposited. It is essentially the cost of borrowing money. When you borrow money, you are obligated to pay back the original sum of the loan plus the interest that accrues on it. The amount of interest charged depends on several factors such as the type of loan, the creditworthiness of the borrower, the length of the loan, and market conditions.

How do interest rates work?

When you take out a loan, the lender will charge you interest on the sum borrowed. The interest rate is determined by the lender based on the factors mentioned earlier. The interest is typically calculated on an annual basis, and the charge is broken down into monthly payments. So, if you borrow $10,000 at an interest rate of 5%, you will pay back $10,500 at the end of the year. That’s $10,000 borrowed plus $500 in interest. If you choose to repay the loan over five years, you will pay $175 per month.

Types of interest

There are two types of interest rates: fixed and variable. A fixed interest rate remains the same throughout the loan term, while a variable interest rates fluctuates based on market conditions. Fixed interest rates provide stability and predictability, while variable rates offer the possibility of lower payments but come with the risk of rates rising over time, increasing your costs.

Credit score factor

Your credit score is a significant factor in determining your interest rates. Those with a good credit score will receive lower interest rates than those with poor credit scores. This is because lenders view borrowers with good credit scores as less risky than those with poor credit scores. A credit score of 700 or higher is seen as good, while a score of 600 or lower is considered poor. Those with poor credit scores may have limited options when it comes to borrowing money, and they may have to pay higher interest rates as a result.


Interest rates are an essential aspect of the lending and borrowing process, and it’s crucial to understand how they work when managing your finances. Always know your credit score and explore all of your options before taking out a loan or applying for a credit card. Remember, choose carefully and avoid any decision that could lead to financial problems. By understanding interest rates, you can make better-informed decisions and manage your finances more effectively.
