If your credit score isn't where you want it to be, you're not alone. Millions of Americans are rebuilding credit after late payments, high balances, or past financial setbacks. The good news? Credit scores are based on clear rules—and when you understand what affects your credit score the most, improving it becomes much more manageable.
This guide is written specifically for people with bad or fair credit who want real progress, not confusing jargon.
1. Payment History (35%) — The Biggest Opportunity to Improve
Payment history matters more than anything else. It tracks whether you pay your bills on time, including credit cards, loans, and collections.
If you've missed payments in the past, don't panic. What lenders care about most is recent behavior. Even one or two late payments can hurt, but consistent on-time payments going forward can steadily rebuild your score.
What to focus on right now:
- Pay at least the minimum every month
- Set up autopay to avoid future mistakes
- Bring past-due accounts current if possible
This single habit has the largest impact on rebuilding credit. Learn more about the 35% payment history rule and how it affects your score.
2. Credit Utilization (30%) — The Fastest Way to See Results
Credit utilization is how much of your available credit you're using. High balances are one of the most common reasons people stay stuck with low scores.
For example, using $800 of a $1,000 limit = 80% utilization, which hurts your score—even if you pay on time.
For bad or fair credit, this matters a lot.
Best practices:
- Aim to stay below 30% utilization
- Below 10% is ideal if possible
- Make payments before your statement closes, not just before the due date
Lowering balances often leads to faster score increases than almost anything else. Read our detailed guide on the 30% credit utilization rule for more strategies.
3. Length of Credit History (15%) — Why Patience Pays Off
This factor looks at how long you've had credit. If you're rebuilding, your history may be short—or damaged—but time works in your favor.
Important tip:
Avoid closing old accounts unless absolutely necessary. Even unused cards can help by increasing your available credit and keeping your average account age higher.
Learn more about how account age affects your credit score and why keeping old accounts open matters.
4. Credit Mix (10%) — Helpful, but Not Worth Stressing Over
Credit mix refers to having different types of credit, like cards and loans. While it helps a little, it's not something you should actively chase.
Never take on debt just to improve your credit mix. Focus on the big factors first.
Discover how credit mix impacts your FICO score and when it actually matters.
5. New Credit & Inquiries (10%) — Apply Carefully
Applying for multiple credit cards or loans in a short period can temporarily lower your score. If your credit is already fragile, spacing out applications matters.
Smarter approach:
- Use pre-approval tools when available
- Apply only for cards designed for your credit range
- Avoid unnecessary hard inquiries
Understand the difference between hard and soft credit inquiries and how they affect your score.
What Matters Most If You're Rebuilding Credit?
If your score is under 650, these three actions matter more than anything else:
Never miss a payment
Set up autopay and reminders to ensure every payment is on time.
Keep balances low
Aim for under 30% utilization, ideally under 10%.
Give it time
Credit rebuilding takes patience, but consistent habits pay off.

What Affects Your Credit Scores? - ExperianFinal Takeaway
There's no shortcut to perfect credit—but there is a clear path. If you focus on paying on time, lowering balances, and avoiding unnecessary applications, your score can improve month by month. Many people see meaningful gains within 6–12 months by following these basics consistently.
If you're rebuilding, progress matters more than perfection.
Every on-time payment, every dollar paid down, and every month of responsible credit use brings you closer to your goals. Stay consistent, and the results will follow.
