Understanding Your Credit Score and How to Improve It

How Credit Scores Are Calculated

Your FICO credit score, which is used by 90 percent of lenders, is calculated from five factors. Payment history is the largest at 35 percent, reflecting whether you pay your bills on time. Credit utilization at 30 percent measures how much of your available credit you are using. Length of credit history at 15 percent rewards longer track records. As AnnualCreditReport.com notes, this approach is backed by extensive research.

Credit mix at 10 percent considers the variety of credit types you manage, such as credit cards, auto loans, and mortgages. New credit inquiries at 10 percent tracks how frequently you apply for new credit. Hard inquiries from credit applications temporarily reduce your score by a few points for about 12 months.

Scores range from 300 to 850. A score above 740 is generally considered excellent and qualifies you for the best interest rates and terms. Scores between 670 and 739 are good, while scores below 670 may result in higher interest rates or difficulty qualifying for certain credit products.

Quick Wins for Score Improvement

The fastest way to improve your credit score is to reduce your credit utilization ratio. Pay down credit card balances so that each card and your total utilization is below 30 percent, ideally below 10 percent. If you have a card with a 5,000 dollar limit and a 2,500 dollar balance, that card's utilization is 50 percent. Paying it down to 500 dollars drops utilization to 10 percent.

Request credit limit increases on your existing cards. If your limit increases from 5,000 to 8,000 dollars while your balance stays at 1,000 dollars, your utilization drops from 20 percent to 12.5 percent without paying anything extra. Most issuers allow you to request increases online or by phone.

Become an authorized user on a family member's credit card that has a long history and low utilization. Their positive account history is added to your credit report, potentially boosting your score significantly. This works even if you never use the card yourself.

Long-Term Score Building

Set up autopay for at least the minimum payment on every account. A single missed payment can drop your score by 50 to 100 points and stays on your credit report for seven years. Autopay eliminates the risk of accidentally missing a due date, which is the most common cause of payment history damage. For a deeper look at the numbers, visit Investopedia.

Keep old credit card accounts open even if you no longer use them. Closing old accounts shortens your average credit age and reduces your total available credit, both of which can lower your score. If a card charges an annual fee, ask to downgrade to a no-fee version rather than closing the account entirely. Looking for the next step? Read about staying debt-free after payoff.

Be patient. Credit score improvement is a marathon, not a sprint. Most score-boosting actions take 30 to 60 days to fully reflect in your credit report. Major improvements from reducing utilization and building payment history compound over six to twelve months of consistent behavior.
