What is a credit limit and does it matter?

KEY POINTS:
- A ‘credit limit’ is the maximum amount of money a lender will loan to you.
- Financial institutions have rules for ‘over-the-limit’ spending, which you should find out before signing up.
- How much you have borrowed or have applied to borrow will be listed on your credit report.
What is a credit limit?
A ‘credit limit’ is the maximum amount of money a lender will loan to you via one of their credit products. The term is widely used across the lending market and can apply to all different kinds of loans, such as home, car, personal or margin loans, but is most often associated with credit cards.
What is a credit limit on credit cards?
When you take out a credit card, you’re signing up for a line of credit from a financial institution. You’re also agreeing that you will pay back the money borrowed under certain conditions. Generally speaking, credit cards are set up so that you can continually borrow portions of loaned money and pay them back according to a schedule. You’re charged interest depending on that repayment schedule.
How does a credit limit on a credit card work?
A financial institution may offer credit card products with different credit limits, such as $2,000, $10,000 or even $50,000.
Let’s say someone chooses a card with a $10,000 credit limit: this means that the total amount of money that person can borrow using that credit card would be $10,000.
That person would apply for the credit card and the financial institution would evaluate their application and decide whether or not to issue the card; considering factors such as their credit score. Upon successful application, that person would receive the credit card (or a virtual version of it) and be able to use it to borrow up to $10,000 for purchases.
For many borrowers, it’s possible to track credit card spending via a bank or lender’s mobile phone app. Fees and charges would also apply, based on the credit card terms and conditions, and be reflected in the statement progressively.
How are credit limits decided?
When you apply for a credit card, you’ll typically get the opportunity to request a credit limit that you’d prefer, or you can let the lender decide for you. Ultimately, the credit card provider will offer you a credit limit that it considers to be appropriate based on your financial situation and ability to pay off the card balance. Even if your application is approved, this amount may be lower than what you requested.
When assessing your ability to manage a credit card, a bank or lender will consider a number of factors, such as your income, assets, expenses and debts. When applying for a credit card as a consumer, it’s also important to keep these factors in mind when deciding what limit might be suitable for you.
Since credit limits are determined by your personal circumstances, the type of credit card you apply for (e.g. low interest rate, no annual fee, frequent flyer etc.) won’t usually have an impact on the credit limit you’re offered.
Can you go over your credit limit?
Whether or not you can spend more than your limit on your credit card depends on the agreement you have with your financial institution. It’s a wise idea to find out what the financial institution’s rules are for ‘over-the-limit’ spending before signing up.
Some agreements do automatically prevent transactions being made once the credit limit has been reached. In this case, purchases could be declined once a user has spent up to their allowable limit.
Some financial institutions allow credit card holders to ask that they not be allowed to exceed their credit limit, to help them to control their debt levels. Other financial institutions will only allow certain eligible cardholders to exceed their limit, such as those with a strong credit history.
If you do spend over your credit limit, you may be charged a fee or have to pay a higher rate of interest, but this comes down to your credit contract.
Not all banks charge ‘over-the-limit’ (also called overlimit) fees. But any purchase made via a credit card is added to the balance of the card, which means you still have to pay it back within a certain amount of time, typically with interest.
Even if you don’t plan on spending more than your credit limit, credit card fees and charges could lead to your account becoming overdrawn. Your personal credit score may be negatively affected if you don’t make regular repayments on your credit card.
Can you change your credit limit?
Generally speaking, you can request to raise or lower your credit limit via online banking, over the phone or at a branch—depending on your lender. When requesting to raise your limit, your lender is under no obligation to approve your application, and will typically ask you to provide information about your current financial situation. This information may include your income, credit score, assets, expenses and other debts such as other credit cards or loans. This ensures that the new proposed credit limit suits your needs.
You can usually lower your credit limit whenever you want, however, there may be minimum credit limits that apply to your credit card.
Does increasing your credit limit hurt your credit score?
Increasing your credit limit can have an impact on your credit score, especially if you have a large limit already. If you request an increase, your lender may do a credit check, which would appear on your credit report as an enquiry. If you make multiple credit enquiries in a short period of time it could lower your credit score. This is due to financial institutions making the assumption that you’re in desperate need of credit and that you may not be in a stable financial position. Lenders also typically see larger credit limits as larger potential forms of debt.
It’s wise to check your credit score before you apply to increase your limit. You can check your credit score for free with Canstar or via the Canstar app.
Why does your credit limit matter?
Credit limits are important because they can determine:
1. How much you can spend: Credit limits determine how much money you will have at your disposal to make purchases. Compared to other types of loans, credit cards are typically more flexible in terms of when and where you can spend the funds and what you can spend it on. For example, credit cards typically allow you to borrow a succession of small or larger sums, and use them to buy whatever you need (providing the seller accepts the type of credit card that you have). Whereas if you take out a car loan, for example, you’ll have to use the loan to purchase a vehicle.
Keep in mind, though, that money borrowed on a credit card has to be paid back under strict conditions, and typically attracts a higher interest rate for unpaid balances than some other forms of credit.
2. How much potential debt you want: Your credit limit is the amount of money you can borrow from a financial institution via your credit card. You will be able to borrow up to that amount and pay it back in instalments, with interest applying if payments aren’t made in a specified time frame—usually outside of any interest free days. If you want to try and minimise your debt levels, opting for a lower credit limit may help you control your spending.
Keep in mind that fees and charges, including interest, usually apply when using a credit card, and these can accumulate over time. Developing a budget and learning how to manage expenses effectively can be helpful in minimising overall debt, and you could even consider saving up and creating an emergency fund, instead of relying on credit.
3. Your credit rating: How much you have borrowed or have applied to borrow, will be listed on your credit report. Financial institutions and other parties may check this report which includes information about your credit cards, and what limits those cards have in total. The total credit limit, regardless of how much of that credit you have used, will be considered when calculating your credit score. For example, you could have multiple credit cards with different banks. Your debt level will be calculated by adding up the limits of all of your credit cards. Your repayment history is considered too. Why does this matter? Financial institutions will check your credit score whenever you apply to borrow money, and your score could impact other applications, such as for rental properties.
