Your available credit and the total credit limit on a particular credit card are both tied to the potential amount that you can spend. Your credit limit is the total amount of credit that the card issuer is willing to lend you. On the other hand, your available credit is the potential amount you can spend right now.

Unlike your credit limit, your available credit takes into consideration your outstanding balance and any pending charges. So, for example, if your total credit limit is $10,000, and you have an outstanding balance of $2,000, then your available credit is $8,000.

What Is Available Credit?

Your available credit on a credit card is the total amount that you can spend on your credit card. It is usually calculated as the total credit limit minus any outstanding balance or pending charges. If you attempt a transaction that is larger than your available credit, the credit card company will typically decline the transaction.

What Is a Credit Limit?

The way most credit cards work is that the credit card company issues you a maximum amount that they are willing to lend you. This is called your credit limit. It is usually determined by your financial information, such as your credit score, income, and other items on your credit history.

Why Is Available Credit Important?

Your available credit is one of the most important things about your credit card. The amount of available credit you have is the total amount of money that you can spend on your credit card. If you try to make a purchase that’s more than your total available credit, your credit card company will usually decline your transaction.

Differences Between Credit Limit and Available Credit

The main difference between credit limit and available credit is one of a theoretical limit vs. a limit in practice.

Your credit limit is the theoretical limit that represents how much the credit card company is willing to lend you. If you’ve used a portion of your credit limit, then that amount is subtracted from your total credit limit and becomes your available credit. This is the maximum amount that you can spend right now on your credit card.

In other words, your credit limit will generally remain the same, whereas your available credit will vary based on your spending. When you haven’t spent any money using your credit card, meaning your balance is $0, your credit limit and available credit are the same.

What Happens If You Go Over Your Available Credit?

If you have a credit card balance or outstanding pending charges on your credit card, those amounts are subtracted from the total credit limit that you have on that card. This marks your current available credit, and it’s the maximum amount that you can charge on your credit card at the current point in time.

If you try to make a charge for more than your available credit, it’s likely that your credit card company will decline the charge. With some credit card companies or specific credit cards, it’s possible that the credit card company will allow a charge above your available credit, but they may charge interest and/or additional fees. Check with your credit card company for the specific rules and terms for your particular card.

What Happens If You Go Over Your Credit Limit?

If you continue to spend all of your available credit until you’ve reached your total credit limit, you may not be able to continue to use your credit card. You’ll first need to make payments to lower your total balance and raise your available credit.

In some cases, if you continue to keep your outstanding balance near your total credit limit, the credit card company may choose to close your credit card account. If this doesn’t happen, your card issuer may also increase your interest rate, lower your credit limit, or even raise the minimum payment requested.

Going over your credit limit can also have serious implications for your credit score. This is because credit utilization — how much of your available credit you’re currently using — is a major factor used to determine your score. It’s recommended to keep your credit utilization ratio below 30% to maintain a healthy score; if you’ve reached your credit limit, your utilization will be at 100%.

How to Increase Your Available Credit

The best way to increase the available credit on your credit card is to spend less on your card and make additional payments toward your total outstanding balance. Every dollar that you pay toward your outstanding balance will increase your available credit.

Ideally, you’d get to a situation where you’d pay off your statement balance in full, each and every month. In that scenario, your available credit and your total credit limit would be equal.

How to Increase Your Credit Limit

You have a few options for increasing your credit limit. Some credit card companies will regularly review the accounts of their cardmembers, and proactively increase their credit limits.

You also have the option to contact your card issuer directly and ask them to increase your credit limit. Keep in mind that most issuers are more likely to increase your credit limit if you’re already using your credit card responsibly.

If you’re not having any luck increasing the credit limit on your existing credit card, another option is to open a new credit card. This could substantially increase your available credit if you’re approved — especially if the new card’s limit is at or above the average credit card limit.

The Takeaway

Your total credit limit and available credit are two terms that refer to the amount of money that you can spend on your credit card. However, there is a difference between credit limit and available credit. Your credit limit usually refers to the maximum amount that your card’s issuer is willing to lend you. Meanwhile, your available credit is the maximum credit limit, minus any outstanding balance or pending charges on the card.

Whether you're looking to build credit, apply for a new credit card, or save money with the cards you have, it's important to understand the options that are best for you. Learn more about credit cards by exploring this credit card guide.

FAQ

Why is my available credit less than my credit limit?

Your available credit will often be less than your credit limit based on any outstanding balance or pending charges that you have on your credit card. If you have a total credit limit of $7,500 on a particular card, and an outstanding balance of $1,000, then your available credit is $6,500. The available credit amount is the maximum amount that you can charge on your credit card at the current moment.

Why is my available credit higher than my credit limit?

It’s rare that your available credit will be higher than your total credit limit. Instead, it’s much more common for your available credit to be less than (or equal to) your total credit limit. One scenario where your available credit may be higher is if you have a credit on your account, such as from a refunded transaction.

How is my credit limit determined?

Credit card issuers typically determine your total credit limit based on the financial information that you provide when you apply for the card. This includes your employment information, salary, and overall creditworthiness. If your financial situation has materially changed since you first applied or if you have a history of responsibly using your card, you may be able to contact your issuer and have your credit limit increased.

What is a good amount of available credit?

Currently the average credit card limit was just over $30,000, though credit limits vary widely by card issuer, credit card, and individual. A good amount of available credit is one that allows you to make all of the transactions that you need to make each month, with a little bit of buffer room, and without your utilization going above 30% of your limit. You should aim to put yourself into a financial position where you can pay off each of your credit card statements in full, each and every month.

SOCC-Q224-1910959-V1

If you’re asked to insert or tap rather than swipe your credit card when you go to pay, you’re using a chip credit card. A credit card chip is a small gold or silver microprocessor that’s embedded in the card and intended to offer greater security for your transactions.

Credit card chips are growing dominant in the plastic payment market. These chips — sometimes known as Europay, MasterCard, and Visa (EMV) chips — comprised about 93% of global credit card transactions in the most recent year studied, though US usage was slightly lower at 87.2%. Overall, there are almost 13 billion cards with these chips in circulation. Read on to learn more about how the credit card chip works.

What Is a Credit Card Chip?

Credit card chips are small microchips embedded in the card that collect, store, and transmit credit card data between merchants, their customers, and participating financial institutions. Each time you use a credit card, these chips generate a unique code that can only be used for that transaction.

Chip credit cards date back to the mid-1990’s, when the three titans of card payment technology — Europay, MasterCard, and Visa — collectively rolled out the first chip-based credit card to the masses. Also known as EMV chips, credit card chips were introduced as a way to enhance payment security over the existing magnetic-strip credit cards.

Today, chip credit cards continue to grow in popularity. Contactless credit cards are another advancement underway.

Magnetic Strip vs Chip Credit Cards

Magnetic-strip cards hold data on the magnetic strip that appears on the back of payment cards. Because these strips hold all of a cardholder’s information needed to make a purchase, this type of card is an easy target for thieves.

With industry-wide concerns over data fraud linked to magnetic stripe cards, credit card companies turned to advanced computer microchips as a solution to credit card data security problems, using EMV technology.

Chip-based payment cards have a big advantage over magnetic-strip cards, as each card payment transaction generates a unique data code. Because the chip’s code is a “one and done” feature that disappears after the transaction is completed, even if data fraud criminals uncover the code, they can’t use it for future transactions.

How Does a Chip Credit Card Work?

Chip credit cards don’t work on a standalone basis. Merchants who want to conduct card payment transactions need payment processing tools, like card terminals and mobile scanners, that are compliant with EMV chip industry standards.

•   When a consumer inserts a chip credit card into a payment terminal (unlike with a contactless payment), and follows the on-screen prompts to complete the transaction, the chip and the terminal exchange the needed data in an encrypted code.

•   That code is then used to transmit the transaction details to the acquiring bank, which quickly reviews the transaction.

•   After the cardholder’s financial data is authenticated and it’s determined the consumer has the funds to cover the purchase, the payment software may run fraud filters to further authenticate the user and the transaction.

•   Then, the transaction is approved by the acquiring bank (or declined if the consumer doesn’t have the funds to cover the purchase or if fraudulent activity is suspected). The appropriate transaction confirmation codes are relayed back to the EMV payment device in real time, thus concluding the transaction.

•   Assuming the transaction is approved, the embedded card chip transmits the approval to the cardholder’s bank, which releases funds to pay for the transaction and sends it to the acquiring bank.

•   The transaction is then settled by the merchant’s payment provider and deposited into the merchant’s bank account.

Types of EMV Cards: Chip-and-Signature vs Chip-and-PIN

If you are using an EMV chip card these days, you probably know that many retailers don’t require a signature or PIN. You just tap, wave, or insert the card, and you’re all done. Many of the major card companies did away with the signature requirement.

However, you may still have another step when you use your credit card, depending on which of the two main types of chip-based cards you have:

1.    Chip-and-signature cards: The most widely used form of EMV card in the U.S. is the chip-and-signature card. With these, the cardholder simply inserts the card into the point-of-sale terminal and then provides their signature to verify the transaction.

2.    Chip-and-PIN cards: With a chip-and-PIN card, the cardholder is asked to enter a four-digit PIN, or personal identification number, at the point of sale. That process authenticates the user and allows for the card transaction process to be completed.

While each type of chip-based payment card model serves the same function — the safe and efficient completion of a transaction — chip-and-pin cards may be the safer alternative.

That’s because with a chip-and-signature card, the cashier or front of the store service provider may not ask to see the back of the card to manually authenticate the signature. That gives fraudsters a leg up, since their signatures may not be checked. With a chip-and-pin card, on the other hand, the thief would need to know the credit card PIN to complete a transaction.

Protecting Yourself From Credit Card Fraud

While chip-based credit and debit cards have been a game-changer in improving payment security, card thieves still have ways to either steal your card or lift sensitive personal data from a payment card.

Here are some ways you can protect yourself against credit card fraud:

•   Review your card statements. One of the important credit card rules to follow is checking your card statements regularly for potential security issues. If something looks suspicious, immediately contact your credit card issuer. In the case of unauthorized charges, report the fraudulent activity and follow the steps recommended by the card company, which could include freezing the card temporarily or getting a new card.

•   Keep physical possession of the card at all times. A cardholder’s best defense against physical card theft is to always know where their card is and only carry it when needed. It’s also a good idea to avoid storing your card account number on a digital device — particularly sensitive information like the credit card CVV number — that could be stolen by a savvy cyber thief.

•   Shred any documents that contain sensitive information. To further protect your account information, shred physical payment card files that include your credit card or account number once you’ve paid your monthly bill. Better yet, sign up for paperless billing, so there’s no paper trail at all.

•   Watch out for email scams. Steer clear of “phishing” scams, i.e., fraudulent emails or texts pretending to be from trusted retailers and financial institutions. If you receive an email requesting sensitive information, reach out to the company directly using the contact information listed on their website or on the back of your card.

The Takeaway

The introduction of credit card chips has greatly increased the security of credit card transactions. Credit card chips generate a unique code for each transaction, and that code cannot be used for future transactions. This makes it harder for thieves to intercept your personal data — though that doesn’t mean credit card fraud isn’t still possible.

FAQ

What is the chip on credit cards?

A credit card chip is a microchip embedded into a credit or debit card that securely stores transaction data. This helps to facilitate safe and efficient payment card transactions.

Are chip-and-signature cards as safe as chip-and-PIN cards?

Not necessarily. That’s because the merchant may not require a signature or verify it against the one on the back of the card. This means it may be easier for thieves to get away with signing on behalf of the actual cardholder. It’s likely more difficult for a thief to get hold of a cardholder’s PIN.

Do all retailers accept EMV cards?

A high percentage of global retailers accept chip-based credit and debit cards. Industry figures show that EMV chip cards comprised over 90% of the global credit card transactions in the most recent year reviewed.

Is tapping or contactless credit cards safer?

Both are secure ways to make transactions. That’s because both contactless and chip credit card transactions generate a new transaction code for each purchase.

If you unintentionally overpay your credit card bill, you may see a negative balance on your account. Although overpaying a credit card isn’t ideal — that cash flow could’ve been used toward another expense, after all — it’s usually not cause for concern.

If you overpaid your credit card, interest isn’t charged on the amount; in fact, that amount is owed back to you. What you do next, whether that’s requesting a refund or applying the overpayment to next month’s bill, is your choice.

How Credit Card Overpayments Happen

Since credit cards work by providing you with revolving purchasing power up to your limit, any activity on the account can change your available balance — even after you’re issued a monthly billing statement. This includes new purchases on the account that increase your credit card balance, but also payments or credited amounts that lower the outstanding amount you owe.

If you end up making a payment to your credit card issuer for a higher amount than you owe, for instance, it results in an overpayment. This is also called a negative balance.

How You Could Have Overpaid Your Credit Card

There are a few circumstances that might result in an overpaid credit card.

Manual Payments

Submitting a manual credit card payment for an amount that’s higher than your actual outstanding balance will push your account into a negative balance. This might happen if you’ve been repaying a large purchase in equal increments each month, but make a math error or have an oversight.

For example, say you used your new 0% APR credit card to purchase a laptop for $2,150 and plan to make manual monthly payments of $500. By month five, you’d only need to make a $150 payment to pay off your card balance. But if you forget what your current balance is, you might accidentally make another $500 payment. The $350 difference would be an overpayment on your account.

Paying attention to your outstanding balance on the day you plan on making a manual payment can help you avoid overpayment.

Additional Payments on Top of Automatic Payments

You might also overpay credit card balances if you made a payment to avoid credit card interest charges, but didn’t realize that you already had autopay enabled on your account.

The scheduled automatic payment will still be processed, regardless of any manual payments, unless you cancel it for the month. For this reason, a double payment can result in an overpaid credit card.

Before making an extra payment, double-check whether you’ve enacted autopay and see how another payment might affect your outstanding balance.

Receiving Refunds

Another common scenario resulting in an overpaid credit card is if you return a purchase to a merchant or get a refund for a service. If the amount of the purchase was credited back to your credit card and you make a payment based on what’s shown on your statement balance that arrived before this transaction, you’ll overpay your credit card bill.

If you returned an item and received a refund back on your card, remember to adjust your manual payment or autopay to reflect your new balance due.

Guide to Rectify Overpaying Your Credit Card

Now that you know what happens if you overpay your credit card, you may be wondering if there’s anything you can do to fix it. If your credit card balance is under $0, and you’re owed money back, there are a few ways to move forward.

Request a Refund

The Fair Credit Billing Act (FCBA) protects your rights when it comes to how your credit card account is handled. It states that you have the right to request a refund if you overpay your credit card by more than $1.

The credit card rules state that the issuer must give you a refund in the payment method of your choosing within seven business days of receiving your request. Additionally, it must, in good faith, make attempts to return unapplied overpayments that have been on the account for over six months.

When requesting a refund by mail, make sure to send your request through certified mail so you have proof of the date it was received by the bank.

Allow the Negative Balance to Roll Over Next Month

Another way to address a negative balance on a credit card is simply to do nothing. If you don’t explicitly request a refund, the bank will automatically roll over the unapplied credit toward your next statement balance.

If you have a larger statement balance than your credit during the following month, the overpayment credit will be applied and the remaining balance you owe is reduced. However, if your credit is greater than your new statement balance, your adjusted credit amount will roll over again.

It will continue this way until you’ve effectively used all of your account’s overpayment credit or you ask for a refund.

Enable Autopay on Your Credit Card

If you’re not already enrolled in automatic payments, enabling autopay for your credit card bill can help prevent overpayments due to manual payment errors. Leveraging your card’s autopay feature is a responsible way to use a credit card since it ensures you pay the correct amount on your account on time.

If you set up autopay to always pay your statement balance or outstanding account balance, it also helps you avoid credit card debt that’s getting increasingly harder to pay off.

Does an Overpaid Balance Affect Your Credit Score?

Having an overpaid credit card balance is better than having a positive balance on your account. Credit card companies report negative balances as a “zero balance” when forwarding your card activity to the credit bureaus.

A zero balance lowers your credit utilization, which impacts your credit score calculation. Although it can build your credit compared to carrying an outstanding balance, the effect of an overpayment is the same as making a payment for the correct amount to reflect that you owe $0. In other words, it won’t help you build your credit score.

The Takeaway

Although overpaying credit card balances is a common occurrence, following the tips above can help you avoid a negative balance. Paying attention to this can help prevent your discretionary cash flow from getting tied up with your card issuer unnecessarily — a key to smart credit card habits.

Whether you're looking to build credit, apply for a new credit card, or save money with the cards you have, it's important to understand the options that are best for you. Learn more about credit cards by exploring this credit card guide.

FAQ

What happens if I overpay my credit card?

If you overpay your credit card, the amount is reflected as a negative balance on your account balance. You can request a refund or let the bank apply it to your next statement.

Does a negative balance have an effect on my credit score?

No, a negative balance doesn’t affect your credit score. Your bank reports it as a zero balance.

How long do you have to dispute a credit card charge?

You have 60 days to dispute a credit card charge, starting from the date it appears on your statement. The bank is legally required to acknowledge your dispute within 30 days of receiving it. A resolution must be enacted within two billing cycles or a maximum of 90 days from your dispute date.

How can I request a refund after overpaying my credit card?

Send a notification to your bank requesting a refund and specifying the method in which you’d like to receive it, such as a check or other method. Check with your bank about how to submit it. The bank is required to provide your refund within seven business days of your request.
