Your credit score affects more than you think—mortgage rates, car loans, apartment approvals, even job offers. A 100-point difference can cost you tens of thousands in interest over your lifetime.
The good news? Credit scores aren't mysterious. They're calculated using specific factors, and once you understand them, you can systematically improve your score.
What Makes Up Your Credit Score
Payment History
Do you pay on time? The biggest factor by far.
Credit Utilization
How much of your available credit are you using?
Length of Credit History
How long have your accounts been open?
Credit Mix
Do you have different types of credit (cards, loans, mortgage)?
New Credit Inquiries
How often are you applying for new credit?
Notice that 65% of your score comes from just two factors: payment history and credit utilization. Focus there first!
7 Strategies That Actually Work
Pay Every Bill On Time, Every Time
Payment history is 35% of your score. Even one late payment can drop your score 50-100 points and stay on your report for 7 years.
Action Steps:
- ✓ Set up autopay for at least the minimum payment on all accounts
- ✓ Set calendar reminders 5 days before due dates
- ✓ If you miss a payment, pay it ASAP—30 days late is worse than a few days
⚡ Impact: HIGH | Timeline: Immediate prevention, 6+ months to improve
Lower Your Credit Utilization to Under 30%
Credit utilization is how much of your available credit you're using. If you have a $10,000 limit and a $3,000 balance, that's 30% utilization. Lower is better—under 10% is ideal.
Action Steps:
- ✓ Pay down existing balances (start with highest utilization cards)
- ✓ Request credit limit increases (don't spend more!)
- ✓ Pay credit cards twice a month to keep reported balances low
- ✓ Keep old cards open even if you don't use them (for available credit)
⚡ Impact: HIGH | Timeline: 1-2 billing cycles (fastest improvement!)
Don't Close Old Credit Cards
Closing old cards hurts you two ways: it reduces your total available credit (increasing utilization) and can shorten your average account age.
Action Steps:
- ✓ Keep your oldest card open and use it occasionally
- ✓ Set a small recurring charge (like Netflix) on old cards
- ✓ Only close cards with annual fees you can't justify
⚡ Impact: MEDIUM | Timeline: Prevents future damage
Dispute Errors on Your Credit Report
About 1 in 5 credit reports contain errors. These could be accounts that aren't yours, incorrect late payments, or outdated information dragging down your score.
Action Steps:
- ✓ Get free reports at AnnualCreditReport.com (all 3 bureaus)
- ✓ Review every account, balance, and payment status
- ✓ Dispute errors online with each bureau (Experian, Equifax, TransUnion)
- ✓ Bureaus must investigate within 30 days
⚡ Impact: VARIES (could be huge!) | Timeline: 30-45 days
Become an Authorized User
If a family member has a credit card with a long, positive history, ask to be added as an authorized user. Their good payment history can boost your score.
Important Notes:
- ✓ Choose someone with excellent payment history and low utilization
- ✓ You don't even need to use or possess the card
- ✓ Their negative activity could hurt you, so choose wisely
⚡ Impact: MEDIUM-HIGH | Timeline: 1-2 billing cycles
Limit Hard Inquiries
Each time you apply for new credit, a hard inquiry hits your report. Too many in a short period signals risk to lenders.
Action Steps:
- ✓ Only apply for credit you actually need
- ✓ Rate shopping for mortgages/auto loans? Do it within 14-45 days (counts as one inquiry)
- ✓ Use pre-qualification tools that do soft pulls first
⚡ Impact: LOW-MEDIUM | Timeline: Inquiries fall off after 2 years
Use a Credit-Builder Loan or Secured Card
No credit history? These tools help you build credit from scratch by reporting your payments to credit bureaus.
Options:
- ✓ Secured Credit Card: Put down a deposit that becomes your limit
- ✓ Credit-Builder Loan: Payments held in savings, released when paid off
- ✓ Experian Boost: Add utility/phone payments to your Experian report
⚡ Impact: MEDIUM | Timeline: 3-6 months to see improvement
Credit Score Ranges
| Score Range | Rating | What It Means |
|---|---|---|
| 800-850 | Exceptional | Best rates, easiest approvals |
| 740-799 | Very Good | Excellent rates, easy approvals |
| 670-739 | Good | Good rates, most approvals |
| 580-669 | Fair | Higher rates, some limitations |
| 300-579 | Poor | Difficulty getting approved, high rates |
