An authorization charge is a temporary hold your bank places on your account when you use a debit or credit card, before the merchant actually charges you
When you swipe your card at a gas pump, hotel, or restaurant, the merchant doesn't know the final amount right away. A gas pump doesn't know how much fuel you'll buy. A hotel doesn't know if you'll order room service. So the merchant asks your bank to authorize — to confirm you have funds or credit available — for an estimated amount. Your bank puts that amount on hold. It looks like a charge on your statement, but it isn't money leaving your account yet.
The authorization hold typically disappears within three to five business days, even if the merchant never actually charges you. When the merchant does settle the final charge — the real amount you actually owe — that's when money actually moves. If the final charge is less than the authorization, you get the difference back. If it's more, your bank covers it because the authorization already confirmed you had the funds.
Authorization charges are normal and happen thousands of times a day. They protect both you and the merchant. But they can cause real problems if you don't understand them: they can make your available balance look lower than it actually is, and they can cause overdrafts if you're not watching carefully.
Key Takeaways
- An authorization hold is not a real charge — it's a temporary freeze on funds to confirm you can pay, and it releases within three to five business days.
- The final charge from the merchant may be different from the authorization amount, and your bank will adjust your account once the real amount settles.
- Authorization holds reduce your available balance even though the money hasn't actually left your account, which can trigger overdrafts if you're not careful.
- Gas pumps, hotels, restaurants, and rental car companies use authorizations most often because they don't know the final amount at the time of the transaction.
- If an authorization doesn't release after five business days, contact your bank or the merchant to find out why it's still pending.
Where authorization charges show up on your statement
Authorization holds appear in your pending transactions section, not your posted transactions. Most banking apps and online portals separate these two. Pending means the transaction is in progress. Posted means it's final and the money has moved.
Your available balance reflects both posted charges and pending authorizations. So if you have $500 in your account and a $50 authorization hold is pending, your available balance shows $450 — even though no money has actually left. This is why your available balance can look very different from your account balance. The account balance is what you actually have. The available balance is what you can spend right now.
When you look at your statement online or on your phone, scroll down to see pending transactions separately. Some banks show them at the top in a different color. Others require you to tap a "pending" tab. If you only look at posted transactions, you'll miss the holds and think you have more money than you actually do.
Why merchants request authorization holds
Merchants request authorizations for transactions where the final amount is unknown at the time you pay. A gas station doesn't know if you're buying $20 or $60 of fuel. A hotel doesn't know if you'll charge meals to your room. A rental car company doesn't know what damage fees might explore. So they authorize a higher amount — often $1 to $5 more than they expect to charge — to make sure they can collect the real amount later.
The authorization also protects you. It confirms your card is valid and you have funds before the merchant hands over goods or services. Without it, a merchant could give you a hotel room or rent you a car, and then discover your card was declined or you had no funds. The authorization prevents that problem.
Some merchants are more aggressive with authorization amounts than others. A gas pump might authorize $100 even if you only buy $30 of fuel. A restaurant might authorize 20% more than your bill to account for a tip you haven't decided on yet. These practices are legal, but they can make your available balance drop faster than you expect.
How long authorization holds last
Most authorization holds release within three to five business days. This is the standard window across most banks and card networks. The merchant sends a final settlement to your bank, your bank compares it to the authorization, and the hold releases. If the final charge is less, the difference goes back into your available balance when ready. If the final charge is more, your bank covers it because the authorization already confirmed you had the funds.
Some merchants are slower to settle than others. A restaurant might settle the same day you pay. A hotel might wait until the day you check out. An online retailer might wait several days. During this time, the authorization hold stays on your account, reducing your available balance.
If an authorization hold is still pending after five business days, contact your bank. It may be stuck in the system, or the merchant may not have settled it. Your bank can investigate and release it manually if needed. This is rare, but it happens — especially with small merchants or international transactions.
Authorization holds and overdraft risk
Authorization holds can cause overdrafts even though no real charge has posted yet. Here's how: you have $300 in your account. You authorize a $100 hold at a gas pump and a $150 hold at a restaurant on the same day. Your available balance drops to $50. Then you try to buy groceries for $75. Your bank declines the transaction because your available balance is only $50, even though your actual account balance is still $300. Or, if you have overdraft protection, the $75 charge goes through and you overdraft because the pending holds plus the new charge exceed your balance.
To avoid this, check your available balance — not just your account balance — before spending. If you see large pending authorizations, wait for them to release before making other purchases. Keep a mental buffer between what you think you can spend and what your available balance actually shows.
Some banks let you temporarily increase your overdraft limit or turn off overdraft protection if you know you're going to have multiple authorizations pending. Call your bank to ask what options are available on your account.
Authorization holds vs. actual charges
The key difference is timing and certainty. An authorization is a request to hold funds. A charge is the actual movement of money. An authorization can be released without ever becoming a charge. A charge is permanent until you dispute it.
Example: you authorize $100 at a hotel but only stay one night and check out early. The hotel might authorize $100 but only charge $75. The $25 difference releases back to your account within a few days. You were never charged $100 — the authorization just confirmed you could pay up to that amount.
Another example: you authorize $50 at a gas pump but pump $65 of fuel. The pump authorized $50, but the final charge is $65. Your bank covers the extra $15 because the authorization confirmed you had funds. You see a $65 charge post to your account, not $50.
How to manage authorization holds
First, separate your available balance from your account balance in your mind. Your available balance is what you can actually spend right now. Your account balance is what you have, but some of it is on hold. Check your available balance before making purchases, not just your account balance.
Second, be aware of which merchants use authorizations. Gas stations, hotels, restaurants, rental car companies, and some online retailers almost always use them. Grocery stores and retail shops usually don't — they charge the exact amount when ready. Knowing this helps you predict when your available balance will drop.
Third, if you see an authorization that looks wrong — the amount is way higher than you expected, or it's from a merchant you don't recognize — contact your bank right away. Your bank can investigate and release it if it's fraudulent. Don't wait for it to release on its own.
Fourth, keep a buffer in your account. Don't spend down to your last dollar. Authorization holds can surprise you, and having a cushion prevents overdrafts.
Frequently Asked Questions
Can an authorization charge become a real charge if I don't do anything?
No. An authorization is just a hold. The merchant has to send a final settlement for a real charge to post. If the merchant never settles, the authorization releases after three to five business days and you're never charged. You don't have to do anything to stop it from becoming a charge.
Why is my available balance so much lower than my account balance?
Pending authorizations are reducing your available balance. Check your pending transactions to see what holds are active. Once those authorizations release or settle, your available balance will go back up. Your account balance is the true amount you have; your available balance is what you can spend right now.
What if a merchant charges me more than the authorization amount?
Your bank will cover the difference because the authorization already confirmed you had the funds. You'll see the higher charge post to your account. If you think the charge is wrong, you can dispute it with your bank within 60 days, and they'll investigate.
How do I stop authorization holds from happening?
You can't stop them completely if you want to use your card at gas pumps, hotels, or restaurants — those merchants require authorizations. You can use cash or a debit card with a PIN instead of a signature, but most merchants will still request an authorization. The best approach is to understand they're coming and manage your available balance accordingly.
Can an authorization hold cause an overdraft?
Yes. If your available balance drops below zero because of pending authorizations, and you try to make another purchase, your bank may decline it or charge you an overdraft fee. Check your available balance before spending, and keep a buffer in your account to avoid this.
