How Credit Scores Work
| Factor | Weight | What It Means |
|---|---|---|
| Payment History | 35% | Do you pay on time? |
| Credit Utilization | 30% | How much of your credit limit are you using? |
| Length of Credit History | 15% | How old are your accounts? |
| Credit Mix | 10% | Variety of credit types (cards, loans, mortgage) |
| New Credit Inquiries | 10% | How recently did you apply for new credit? |
Score Ranges (FICO)
| Score Range | Category | Typical Impact |
|---|---|---|
| 800–850 | Exceptional | Best rates on all products |
| 740–799 | Very Good | Better than average rates |
| 670–739 | Good | Most products available |
| 580–669 | Fair | Higher rates, some rejections |
| Below 580 | Poor | Difficult to get approved |
7 Steps to Improve Your Score
Step 1: Get Your Free Credit Report
Go to AnnualCreditReport.com — the only federally authorized free report site. Pull reports from all three bureaus (Equifax, Experian, TransUnion). You're entitled to one free report from each per year.
Step 2: Dispute Any Errors
Studies show 1 in 5 credit reports contains an error significant enough to affect lending decisions. Look for: accounts that aren't yours, incorrect late payments, wrong balances, or duplicate accounts. Dispute errors directly with each bureau online — resolved disputes can boost scores by 20–100+ points.
Step 3: Pay Down Credit Card Balances (Biggest Quick Win)
Credit utilization — the ratio of balance to credit limit — accounts for 30% of your score. The sweet spot is under 10% utilization per card (under 30% at minimum). If you have a $5,000 credit limit, carrying over $500 is hurting your score.
Step 4: Never Miss a Payment Again
Set up autopay for every account — at minimum the minimum payment. A single 30-day late payment can drop an 800+ score by 100 points and stays on your report for 7 years. Autopay costs nothing and prevents the single most damaging credit event.
Step 5: Don't Close Old Accounts
Closing a credit card reduces your total available credit (raising utilization) and can shorten your average account age. Keep old accounts open and use them occasionally for small purchases to keep them active.
Step 6: Limit New Credit Applications
Every hard inquiry (credit card, loan, mortgage application) temporarily drops your score 5–10 points. Space out applications and only apply when necessary. Multiple auto or mortgage inquiries within 14–45 days count as one inquiry — rate shopping is protected.
Step 7: Become an Authorized User
Ask a family member with excellent credit to add you as an authorized user on their oldest, lowest-utilization card. Their positive payment history appears on your report — often adding 20–50 points in 30–60 days.
