How to Fix Bad Credit: A Step-by-Step Repair Guide

A bad credit score can cost you tens of thousands of dollars over your lifetime — higher interest rates, denied loan applications, larger security deposits. But bad credit isn't permanent. With the right steps, most people can significantly improve their score within 6-12 months.

What Is Considered Bad Credit?

FICO scores range from 300 to 850. Here's how lenders view the ranges:

• 800-850: Exceptional
• 740-799: Very Good
• 670-739: Good
• 580-669: Fair
• 300-579: Poor (bad credit)

Step 1: Get Your Free Credit Reports

Start by pulling your free credit reports from all three bureaus (Equifax, Experian, TransUnion) at AnnualCreditReport.com. You're entitled to one free report per bureau per year. Review each carefully.

Step 2: Dispute Errors — This Is Critical

Studies show that 1 in 5 credit reports contains errors. Common errors include: accounts that aren't yours (identity theft or mixed files), incorrect balances, accounts shown as open that you closed, duplicate accounts, and incorrect late payment records.

Dispute errors directly with the credit bureau (online or by mail). They have 30 days to investigate. Removing a single error can boost your score by 50+ points.

Step 3: Pay Down High Balances

Credit utilization — how much of your available credit you're using — makes up 30% of your FICO score. Ideally, keep each card below 30% utilization, and below 10% for the best scores. Paying down a maxed-out card can add 50-100 points quickly.

Step 4: Pay Everything On Time, Without Exception

Payment history is 35% of your score — the single biggest factor. Even one 30-day late payment can drop your score by 100 points. Set up autopay for at least the minimum on every account.

Step 5: Don't Close Old Accounts

Length of credit history matters. Closing an old account shortens your average account age and increases your utilization ratio. Keep old accounts open even if you don't use them.

Step 6: Add Positive Accounts

• Secured credit card — you deposit money as collateral, use it like a regular card, and build a positive history
• Become an authorized user on someone else's account (a family member with good credit)
• Credit-builder loan from a credit union or online lender

Realistic Timeline

• 1-3 months: Dispute errors, pay down balances — see early improvements
• 6 months: Consistent on-time payments start showing significant impact
• 12 months: Major improvement possible from Poor to Fair or even Good
• 24 months: Most negative items' impact fades; score can fully recover
