What Determines Your Credit Score?

July 03, 2018

So often, we hear about how important it is to build good credit. After all, having a good credit score opens the door to more financial possibilities, such as purchasing a home.

But many of us (maybe even most of us) don’t know exactly how a credit score is determined. Paying your bills on time is only a small part of the overall big picture!

So, to bring you up to speed, let’s take a look at the components of a credit score from information we gathered from FICO (Fair Isaac Corporation) …

Payment History (35%)

It’s pretty obvious that paying your bills and debts on time will help improve your credit score. But, if you miss a few payments over the course of several years, don’t lose hope. A few late payments over the course of an otherwise healthy credit history shouldn’t drop your score drastically. And, vice versa, just because you’ve paid EVERY bill on time doesn’t mean you’ll automatically have a high credit score. Remember: payment history is just one piece of the puzzle!

Amount Owed (30%)

Owing money is not a bad thing. We repeat: owing money is not a bad thing! However, it’s important to prevent yourself from being overextended. For instance, if you have a high credit card limit and a low balance that you pay off each month, this will most likely make a positive impact on your credit score. If you have a moderate credit limit and you’re always reaching (or surpassing) that limit, that’s probably going to negatively impact your credit score.


Type of Credit (25%)

Type of credit is divided into two categories: length of credit history (15%) and credit mix (10%). Basically, it’s better to have credit lines that are open for longer periods of time. Plus, a variety of credit lines can also be beneficial to your credit score (so, for instance, a mix of credit cards, store credit cards, mortgage loans, and car loans will help boost your score – if those accounts are paid on time.)

New Credit (10%)

Opening new accounts is generally a good thing, but just make sure you’re doing this in moderation. If you open four new credit cards in a six-month time period, for example, this could potentially lower your credit score. The key is to make changes gradually, so you don’t overextend yourself with too many accounts.


Everyone’s situation is unique, but these are some general guidelines that you can take into consideration as you improve or continue to maintain your credit score. Remember, talking to a professional financial advisor is your best bet for gaining personalized, expert guidance on building your credit.
