Understanding What Affects Your Credit Score
Your credit score is calculated from five factors:
- Payment history (35%) — Have you paid bills on time?
- Credit utilization (30%) — How much of your available credit are you using?
- Length of credit history (15%) — How long have your accounts been open?
- Credit mix (10%) — Do you have different types of credit?
- New credit inquiries (10%) — Have you applied for credit recently?
The fastest gains come from improving payment history and credit utilization — which together account for 65% of your score.
The 90-Day Credit Score Boost Plan
Days 1-7: Foundation
Pull your three bureau credit reports
You need reports from Equifax, Experian, AND TransUnion. Errors on even one bureau can drag your score down. WalletHub Premium gives you three bureau credit reports with daily updates so you always have the latest data.
Dispute all errors
Look for:
- Accounts you don't recognize (possible identity theft)
- Late payments that were actually on time
- Incorrect balances or credit limits
- Closed accounts reported as open
- Duplicate accounts
File disputes online with each bureau. Errors are corrected within 30-45 days, and removing a single negative item can boost your score by 20-50 points.
Use a credit score simulator
WalletHub's credit score simulator lets you model exactly how each action will impact your score. Before you do anything, simulate it first.
Days 8-30: Quick Wins
Pay down credit card balances
Getting your credit utilization below 30% can boost your score immediately. Below 10% is even better. Focus on cards closest to their limits first.
Request credit limit increases
Call your credit card companies and ask for higher limits. This instantly lowers your utilization ratio without paying down a cent. (Don't use the new credit — the goal is a lower ratio.)
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 history gets added to your report.
Use Score Boost tools
WalletHub Premium's Score Boost feature identifies specific actions you can take for maximum impact on your score.
Days 31-60: Build Momentum
Set up autopay on everything
Payment history is 35% of your score. One missed payment can drop your score by 100+ points. Autopay eliminates this risk entirely.
Keep old accounts open
Length of credit history matters. Even if you don't use an old credit card, keep it open. Closing it shortens your average account age and reduces available credit.
Apply for a credit builder loan
Services like Self or credit union secured loans report positive payment history to all three bureaus, building your credit mix and payment history simultaneously.
Days 61-90: Protect Your Progress
Monitor with credit alerts
Set up credit alerts through WalletHub Premium to get notified of any changes — positive or negative — on all three bureau credit reports.
Watch for identity theft
As your score improves, protect it. Identity theft protection, data breach monitoring, and dark web monitoring ensure no one undoes your hard work.
Simulate your next moves
Use the credit score simulator to plan your next 90 days. Should you apply for a new card? Pay off a specific debt? The simulator tells you exactly what to expect.
