A checking line of credit, also known as an overdraft line of credit, is a type of loan that is attached to your checking account. It essentially acts as a safety net, providing you with access to funds when your checking account balance is insufficient to cover a transaction.
A checking line of credit can help you out during a cash crunch and allow you to avoid hefty overdraft fees, missed payments, and the embarrassment and inconvenience of having your debit card denied. However, these accounts come with costs and risks of their own. Find out if opening a checking line of credit is worth it.
How a Checking Line of Credit Works
A checking line of credit is a type of revolving credit linked to your checking account. If your account balance falls below zero, the credit line automatically covers the shortfall up to your credit limit. This allows transactions to go through despite insufficient funds and avoids bouncing checks, missing automatic payments, or having your debit card denied.
A per-transfer fee may apply, but it may be much less than what you would otherwise be charged for overdrawing your account. You’ll also pay interest on the borrowed balance, which will begin accruing on the date of transfer and continue until you pay off the borrowed funds in full. Missing or late payments can negatively impact your credit, so (like any other forms of borrowing) it’s important to manage a checking line of credit responsibly.

Key Features
Here’s a look at some of the features offered by a checking line of credit.
• Automatic overdraft protection: A checking line of credit can automatically cover overdrafts, preventing declined transactions and bounced checks.
• Credit limit: The amount you can borrow is predetermined by the lender and may range from $250 to $5,000, though it can be higher for those with excellent credit.
• Variable interest rates: Interest is charged only on the amount you borrow, and rates are usually variable, meaning they can change over time based on market conditions.
• Revolving credit: Similar to a credit card, you can borrow, repay, and borrow again up to your credit limit without reapplying.
• Fees: Some banks charge you a fee for each transfer from your checking line of credit or for each day that a transfer is made from your line of credit to your checking account. Some institutions may also charge a yearly maintenance fee.

Requirements and Eligibility
Not everyone who has a checking account can open a line of credit. Depending on your bank, you may have to meet certain eligibility requirements. These may include:
Good Credit History
Lenders generally look for applicants with a strong credit history, indicating responsible credit management. A good credit score (typically 670 or higher) increases your chances of approval and may result in a higher credit limit and lower interest rates.
Income and Debt Levels
Lenders typically want to make sure that you have a stable income and manageable debt levels, demonstrating your ability to repay the borrowed amount. Banks can check your current debt levels by accessing your credit reports. You may need to provide proof of income, such as pay stubs or tax returns.
Existing Banking Relationship
You typically need to have a checking account in good standing with the bank that offers the protection line of credit. Some banks may also require that you’ve had the account open for a certain amount of time, or that you’ve made deposits within a specific time frame.
Pros of a Checking Line of Credit
Here’s a look at some of the benefits of having a checking account with an overdraft line of credit.
May Save Money
Overdraft lines of credit are often less expensive than standard overdraft protection programs, which can range from $25 to $35 for each overdraft that hits your account. This can be especially true if you wind up making multiple overdrafts in one day.
Offers Emergency Protection
An overdraft line of credit provides you with a safeguard in the event of a financial emergency. If necessary, you can cover essential expenses that would otherwise get declined from your checking account. Some banks also allow you to withdraw funds directly from your credit line to cover emergency expenses.
Only Pay Interest on What Your Borrow
Unlike a traditional loan, where you receive a lump sum amount up front and pay interest on the full amount starting when it’s disbursed, a credit line allows you to borrow funds as needed and only pay interest on the amount you end up borrowing.

Cons of a Checking Line of Credit
Checking lines of credit also come with a few pitfalls. Here are some to be aware of.
High Interest Rates
Interest rates on checking lines of credit can be higher than other forms of credit, such as personal loans or home equity lines of credit. Variable rates can also lead to unpredictable borrowing costs. On top of interest, you may pay transfer fees and account maintenance fees.
Borrowing Limits
An overdraft protection line of credit can help you out in a pinch, but it won’t cover a major unexpected expense. You can often only qualify for credit limits up to $1,000. If your approved line of credit is insufficient to cover a transaction, it likely will not go through.
Debt Cycle Risk
Having a line of credit attached to your checking account is similar to having a credit card — it allows you to spend money you don’t actually have. The ease of access to funds can lead to a cycle of borrowing and repayment that is difficult to break, potentially leading to long-term debt.
When to Consider a Checking Line of Credit
A checking line of credit can provide some peace of mind and be useful for getting through occasional gaps in cash flow. If you do opt for this type of coverage, however, it’s generally wise to use it as little as possible. Once you open the credit line, it’s a good idea to balance your checking account regularly and sign up for low-balance alerts so that you know when you’re running low on funds. This can help keep your overdraft loan at a manageable amount and your interest charges and transfer fees low.
Alternatives to Consider
If a checking line of credit doesn’t seem like the right fit, here are some other options to consider.
• Emergency savings account: Building a savings account for emergencies can provide a financial cushion without the cost of interest or fees.
• Linking to another account: Your bank might allow you to link your checking account to a savings account or another checking account for automatic transfers in case of an overdraft. This way, you’re just using your own money to cover transactions instead of the bank’s.
• Personal loan: For larger, planned expenses, a personal loan may offer lower interest rates and fixed repayment terms.
• Switching banks: If you feel that the overdraft fees (and possibly other fees) at your bank are exorbitant, it can be worth shopping around for checking accounts that charge lower fees.
The Takeaway
A checking line of credit can be a valuable tool for managing your finances, offering convenient access to funds, protection against overdrafts, and the flexibility of revolving credit. That said, it’s important to understand the costs and potential risks associated with this type of credit. Alternatives to checking credit lines include using a linked savings account to cover overdrafts, building an emergency fund, getting a lower-interest loan, and switching to a bank that charges less in fees for standard overdraft protection.

To ensure you're earning the APY for account holders with Eligible Direct Deposit, we encourage you to check your APY Details page the day after your Eligible Direct Deposit posts to your SoFi account. If your APY is not showing as the APY for account holders with Eligible Direct Deposit, contact us at 855-456-7634 with the details of your Eligible Direct Deposit.

There is no minimum Eligible Direct Deposit amount required to qualify for the stated interest rate. SoFi Bank shall, in its sole discretion, assess each account holder's Eligible Direct Deposit activity to determine the applicability of rates and may request additional documentation for verification of eligibility.
