You don't necessarily need a perfect credit score, but having a good credit score can be beneficial in many ways. Your credit score is a measure of your creditworthiness, and it is used by lenders to determine whether or not to approve you for credit, such as a loan or a credit card.
Having a good credit score can help you qualify for better interest rates and terms on loans and credit cards, which can save you money over time. It can also help you get approved for rental applications, cell phone plans, and other services that require a credit check.
A perfect credit score is 850, but very few people have a score that high. Generally, a score of 700 or higher is considered good, while a score of 800 or higher is considered excellent. If you have a score in these ranges, you should be able to qualify for most credit products.
However, it's important to remember that your credit score is just one factor that lenders consider when making lending decisions. Other factors, such as your income, employment history, and debt-to-income ratio, can also affect your ability to get approved for credit.
