Whether you’re borrowing money, saving for the future, or investing in assets, interest rates can significantly affect how much your money grows. Understanding how interest rates work can help you make smarter financial decisions.
An interest rate is the amount of money paid for the use of another person’s or company’s assets. It is typically expressed as a percentage of the principal sum, and it is calculated on a periodic basis, usually at least once a year. There are two main types of interest: simple interest and compounding. Simple interest is a more straightforward formula that only considers the principal sum, while compounding takes both the principal and any additional amounts owed or earned into account.
There are a variety of factors that influence interest rates, including macroeconomic conditions, economic trends, and monetary policy decisions by central banks. High interest rates make it more expensive to borrow money, which can slow economic activity. Low interest rates, on the other hand, can stimulate economic growth by making it more cost-effective to lend and invest.
Borrowers have a choice between variable and fixed interest rates when they take out loans or credit products, such as mortgages, auto loans, personal loans, or credit cards. Each comes with its own benefits and drawbacks, and it’s important for borrowers to understand the differences between them so they can make the best decision for their specific circumstances.
