A personal line of credit (PLOC) affects your credit score by acting as revolving debt, similar to a credit card. Your credit line and account balance factor into your credit utilization, and payments you make on a personal line of credit become part of your payment history. Over time, your PLOC can add to your length of credit history. Here's how a personal line of credit can help or hurt your credit, along with tips for using a PLOC to help build your credit.
What Is a Personal Line of Credit?
A personal line of credit is a revolving line of credit you can access whenever you need it. Any money you use becomes revolving debt you pay back over time just like you would with a credit card, with minimum payments and no early repayment penalty. Limits depend on a variety of factors, including your credit score. Typical lines range from $500 to $25,000 or more. Secured lines of credit that use certificates of deposit or investment accounts as collateral may offer higher limits, depending on the size of the account.
Interest rates on personal lines of credit are generally lower than those on a credit card, starting as low as 7.5% with excellent credit as of September 2026. Some lines of credit charge transaction fees when you draw funds or annual fees for maintaining the account.
Lines of credit have a draw period, typically three to five years, during which you can withdraw money as needed. When the draw period ends, you'll continue paying your outstanding balance until it's paid off, but you can no longer use the account to take out additional money.

How a Personal Line of Credit Can Help Your Credit
Maintaining a personal line of credit can help demonstrate your creditworthiness on certain factors credit scoring models consider: payment history, credit utilization, length of credit history, credit mix and new credit. The following potential benefits of having a personal line of credit might help boost your credit.
Lower Credit Utilization
Adding a personal line of credit raises your overall credit limit, which may lower your credit utilization, or the percentage of available revolving credit you're using. Your credit utilization ratio is calculated by dividing your total revolving debt by your total credit limits on credit cards and personal lines of credit, and the lower your utilization, the better. Credit utilization is part of the amounts owed credit scoring factor, which accounts for 30% of your FICO® Score☉ Θ.
Example: If the credit limits on your credit cards (pre-PLOC) add up to $40,000, and you have $4,000 in combined credit card debt, your credit utilization is 10%. Opening a PLOC with an additional $10,000 limit raises your total credit limit to $50,000 and lowers your credit utilization to 8% (before any draws on the credit line).
On-Time Payments
Your payment history is the most heavily weighted factor in calculating your credit score, accounting for 35% of your FICO® Score. Making consistent on-time payments on your PLOC helps establish a positive payment history.
Longer Credit History
Credit scoring models evaluate your experience with credit by considering how long you've had your accounts. Maintaining a PLOC for multiple years can help improve your length of credit history.
Diverse Credit Mix
Scoring models consider how many types of credit you maintain, including credit cards, installment loans (such as mortgages, personal loans or auto loans) and lines of credit. A personal line of credit can help diversify your credit profile.

How a Personal Line of Credit Can Hurt Your Credit
A personal line of credit can also have a negative effect on your credit, especially if you fall behind on payments or overuse your credit line. Here are four ways a PLOC might hurt your credit, ranging from minor to major.
Hard Credit Inquiries
When you apply for a line of credit, the lender will run a hard inquiry on your credit. A hard inquiry can cause your credit score to drop, though the effect is typically minor and brief.
Term-Limited Account
Your PLOC may affect your length of credit history both when it opens and when it closes.
In the beginning, adding a new account may cause your credit score to dip temporarily. When your line of credit expires, your account will close, which can change your available credit and credit utilization. Credit scoring models may continue to factor in closed accounts when considering your length of credit history, though closed accounts typically fall off your credit report after seven to 10 years—depending on whether your account closed in good standing or not.
Note: Closed accounts with negative marks, including late payments, charge-offs or other derogatory marks, will fall off your credit reports seven years after the date of your first missed payment. Closed accounts in good standing, meaning you paid the account in full and as agreed, will remain on your credit reports for 10 years.
High Credit Utilization
How you use your personal line of credit matters. Debt on your PLOC adds to your revolving debt, similar to your credit card balances. Revolving debt raises your credit utilization. When credit utilization approaches and climbs above 30%, it has a greater potential to harm your credit; people with the highest credit scores tend to keep credit utilization under 10%.
Missed Payments
While on-time payments help build your payment history, even a single 30-day late payment can hurt your credit score. Any additional late payments, collections or defaults can do further damage to your credit. These items appear on your credit report and stay there for seven years.
How to Improve Your Credit With a Personal Line of Credit
Like any type of credit, a PLOC can help you build good credit over time. Use these tips to make the most of your personal credit line.
- Always pay on time. PLOC payments become part of your payment history and every payment counts. Making consistent on-time payments will help your credit score; late and missing payments may bring your score down.
- Keep your utilization low. Try to keep your credit utilization below 30%, both on your PLOC and on your revolving accounts overall. If your utilization is higher than you'd like, take what steps you can to pay down your balance as quickly as possible.
- Use funds strategically. Consider using a PLOC to consolidate high-interest credit card debt and save money on interest charges. Or use it to make a large purchase you want to finance separately, rather than folding it into your existing credit card balance. Being strategic won't affect your credit directly, but it may help you use your PLOC to manage your credit more effectively overall.
- Pay attention to terms. Be mindful of when your PLOC draw and repayment periods end, and plan accordingly. Even after your balance is paid, keep your account open for as long as you can to maintain the length of account history. When your account closes, your total credit limit will drop, causing your credit utilization (if you have outstanding balances) to increase.
- Monitor your credit. Keeping an eye on your credit file is an excellent way to track how your PLOC and other accounts are affecting your credit---and to keep an eye out for problems like identity theft. You can sign up for free credit monitoring from Experian to receive alerts whenever there's a change to your credit file.

As with any type of credit or loan, it's important to understand how your line of credit works upfront, so you can avoid confusion when you need to make payments, manage your credit limit or pay off your remaining balance when your term is up.
