Why Credit Score Matters for Loan Approval
Lenders use credit scores as a key indicator of how likely you are to repay a loan. A higher score typically means you are seen as lower risk, which can open the door to loan approval and more favorable interest rates. The best interest rates are usually offered to borrowers with credit scores in the mid-700s or above.
Payment history is the most important factor in FICO scores, accounting for 35% of the score, while amounts owed (credit utilization) contributes 30%. Other factors include length of credit history, new credit, and credit mix.
If you have a low credit score, lenders may consider you a higher risk and might offer loans with higher interest rates or higher fees, or they might require a co-signer. Understanding these factors can help you prioritize actions to improve your score.
- Payment history: 35% of FICO score
- Amounts owed (credit utilization): 30%
- Length of credit history, new credit, and credit mix make up the remaining 35%
- Scores range from 300 to 850, with higher scores indicating better creditworthiness
- A score below 580 is often considered poor or bad credit

Understand Your Current Credit Report
Before you can improve your credit score, you need to know where you stand. Check your credit report from each of the three major credit bureaus—Equifax, Experian, and TransUnion. You are entitled to a free copy of your report from each bureau every 12 months through AnnualCreditReport.com.
Review your credit report carefully for errors, such as incorrect account information, payments marked late when they were on time, or accounts that do not belong to you. These errors can drag down your score, and you have the right to dispute them with the credit bureau.
Checking your own credit report or score does not hurt your credit score. This is considered a soft inquiry and has no impact on your score.

- Look for errors that could lower your score
- Checking your own report does not affect your score

Dispute Errors on Your Credit Report
If you find errors on your credit report, you can file a dispute with the credit bureau that issued the report. The bureau is required to investigate and correct any inaccurate or incomplete information. Correcting errors can improve your credit score if the disputed items are removed or updated.
The Consumer Financial Protection Bureau (CFPB) provides guidance on how to dispute errors and protects your rights under the Fair Credit Reporting Act. You can file disputes online, by mail, or over the phone with each bureau.
Common errors include accounts that are not yours, incorrect payment status, duplicate accounts, and outdated negative information. Negative items such as late payments and foreclosures generally remain on your report for 7 years, and bankruptcy for 10 years, so if an error is older than that, it should be removed.
- File disputes with each credit bureau individually
- The bureaus must investigate and correct errors
- Disputing errors can lead to a higher score if the error is removed

Reduce Credit Card Balances to Lower Utilization
Credit utilization—the amount of credit you are using compared to your credit limits—is a significant factor in your score, accounting for 30% of your FICO score. Keeping your utilization below 30% of your available credit is recommended to avoid score damage.
If you have high credit card balances, paying them down can have a quick positive effect on your score. You can also consider requesting a credit limit increase, but be aware that this might result in a hard inquiry, which could temporarily lower your score.
One effective strategy is to pay down the cards with the highest utilization first, as that can improve your overall utilization more quickly.
- Keep utilization below 30% of your credit limit
- Pay down high-balance cards first
- Avoid closing old credit cards, as that reduces available credit and can hurt your score

Make On-Time Payments and Set Up Autopay
Your payment history is the most important factor in your credit score, so making on-time payments is crucial. Set up automatic payments (autopay) for at least the minimum amount due on all credit cards and loans to avoid missed payments.
If you have missed payments in the past, getting current and staying current will help over time. Negative items like late payments remain on your report for 7 years, but their impact lessens as they age.
It can take several months of consistent on-time payments to see significant improvement, so be patient and consistent.

Avoid Opening New Credit Accounts Before Applying
Applying for multiple new credit accounts in a short period can hurt your credit score. Each credit application typically results in a hard inquiry, which can cause a small, temporary decline in your score.
Before applying for a personal loan, avoid opening new credit cards, auto loans, or other credit accounts. This includes avoiding store credit card offers that might seem tempting at checkout.
While a single hard inquiry might only lower your score by a few points, multiple inquiries in a short time can add up and signal risk to lenders.
- Hard inquiries from loan applications can cause a small, temporary score dip
- Soft inquiries, like checking your own score or prequalification offers, do not affect your score
- Limit new credit applications in the months before you apply for a loan

Consider Becoming an Authorized User
Becoming an authorized user on someone else's credit card may help you improve your credit score. If you are added to a credit card account with a strong payment history and low utilization, that account's positive history may be reflected on your credit report.
This strategy can be effective, but it depends on the primary account holder's credit behavior. If they miss payments or carry high balances, it could hurt your score. Choose someone you trust and who uses credit responsibly.
Note that not all issuers report authorized user accounts to the credit bureaus, and the impact on your score may vary. The evidence on the extent of benefit is limited, so treat this as a potential supplement to your main efforts.

Track Your Progress and Know When to Apply
Monitor your credit score regularly to see how your actions are affecting it. Many credit card companies and financial apps offer free access to your FICO or VantageScore, and you can also use free services like Credit Karma.
Remember that checking your own score does not hurt it, so you can track your progress without fear of penalty.
When your score has improved and you meet the lender's typical criteria, you can apply with more confidence. However, there is no set timeline for when to apply; it depends on your starting point and the actions you take. Generally, consistent on-time payments over several months can lead to noticeable improvement.
Before applying, consider prequalification offers, which use soft inquiries and do not affect your credit score. This can give you an idea of the terms you might receive without a hard inquiry.
- Check your credit report from each major bureau and review for errors.
- Dispute any errors you find with the credit bureaus.
- Pay down credit card balances to reduce utilization below 30%.
- Set up autopay for at least minimum payments on all accounts.
- Stop applying for new credit accounts at least a few months before applying for the loan.
- If appropriate, become an authorized user on a trusted person's card with good history.
- Monitor your score regularly, and after several months of positive habits, consider a prequalification to see offers.

Frequently asked questions
How long does it take to improve a credit score?
The time varies based on your starting score and the factors you are addressing. Negative items like late payments stay on your report for 7 years, but their impact fades over time. Making consistent on-time payments can lead to improvement within several months, but significant changes may take longer.
Sources: Consumer Financial Protection Bureau, ExperianCan I improve my credit score in 30 days?
Some actions, like paying down credit card balances to lower utilization, can have a relatively quick positive effect on your score, potentially within 30 days. However, major improvements, especially if you have negative marks, typically take longer. There is no guaranteed timeline.
Sources: Consumer Financial Protection BureauDoes checking my credit score hurt it?
No, checking your own credit score or report is a soft inquiry and does not affect your credit score. Only hard inquiries, which occur when a lender reviews your credit for a loan application, can cause a small temporary dip.
Sources: Experian, CredibleWhat is a good credit score to get a personal loan?
Lenders typically consider scores in the mid-700s or above as excellent and likely to receive the best interest rates. However, many lenders offer personal loans to borrowers with bad credit (scores below 580), though terms may be less favorable. There is no single threshold; it varies by lender.
Sources: Consumer Financial Protection Bureau, CredibleShould I use a credit repair service?
Credit repair services can help you dispute errors on your credit report, but you can do this yourself for free. Be cautious, as some services may charge fees and not deliver results. The CFPB provides guidance on how to dispute errors directly with the credit bureaus.
