Two balances, two different questions

The current balance (often called the ledger or posted balance) answers the question: what has already settled in this account? The available balance answers a different question: what will the bank let me spend or withdraw right now? The CFPB describes the ledger balance as the account balance that is not reduced by holds from pending transactions, and the available balance as generally the ledger balance plus any deposits that have not cleared but are made available, less any pending, authorized-but-not-settled debits.

Those definitions explain almost every mismatch you will see. If your available balance is lower, something is pending or a deposit is still on hold. If it is higher, which is rarer, a debit has not yet been authorized or a deposit was made available before it posted. Neither number is wrong; they just measure different moments in the life of a transaction.

Pending debits and authorization holds

When you swipe a debit card, the merchant first asks your bank to authorize the purchase. Capital One describes a pending transaction as a request by a merchant to authorize your purchase, says the amount comes out of your available funds right away, and says pending transactions can remain on the account for up to 5 days until the merchant sends the final amount.

Some merchants authorize an amount that is not the final bill. Capital One lists three common causes: a pay-at-the-pump station charging a small authorization, a restaurant charging the base amount before the tip is added, and a hotel or car-rental agency authorizing an estimated amount for incidentals. Ally's debit card agreement adds that the preauthorization amount may be greater than the actual purchase, that the hold may remain up to three business days after the transaction has been paid, and that holds may affect the funds available to pay checks and other transactions.

The practical takeaway: after a hotel check-in, a rental-car pickup or a fill-up at the pump, assume your available balance is understated for a few days, and do not schedule a large bill payment on the assumption that the hold will drop overnight.

Deposit holds: when a check becomes spendable

Regulation CC sets the outer limits on check holds. Under 12 CFR 229.10, the lesser of $275 or the day's total check deposits that are not otherwise next-day items must be available the next business day. Under 229.12, a local check must be available by the second business day after the banking day of deposit, and 229.12 also requires $550 of those funds to be available for cash withdrawal by 5:00 p.m. on the day they become available, on top of the $275. Cash deposited in person with an employee must be available the next business day; electronic payments the business day after the bank receives them. The $275, $550 and $6,725 figures took effect July 1, 2025 and are adjusted every five years.

Banks may hold longer under 229.13 exceptions: during an account's first 30 days, for check deposits above $6,725 in one day (only the excess), for redeposited checks, for accounts repeatedly overdrawn in the past six months, when there is reasonable cause to doubt collectability, and in emergencies. In most of these cases the bank must give written notice stating the amount delayed, the reason and when the money will be available. The OCC's consumer site summarizes the general rule the same way: the first $275 next business day and the rest generally by the second business day.

Your bank can be faster than the rule. Capital One's 360 Checking disclosures say its general policy makes check deposits available on the first business day after receipt and makes cash and electronic direct deposits available on the day received, with longer delays possible for new customers. Ally's agreement says ACH direct deposits and cash are available the same business day, and some payroll and government deposits may arrive up to 2 business days early without a guarantee. Note one important exception: Ally says checks deposited through its eCheck mobile service are not subject to Regulation CC availability requirements, so mobile deposits follow the bank's own policy.

Worked example: one week with a gas hold and a check deposit

The figures are invented to show the mechanics. Jordan starts Monday with $500 posted and nothing pending. The gas station authorizes $150 at the pump; the fill-up is $46. To show the case that surprises people, this bank leaves the full hold in place until Thursday, which Ally's agreement permits for up to three business days after the purchase is paid. Jordan deposits a $700 local paper check with a teller on Tuesday, and this bank shows it in the current balance right away while releasing it on the Regulation CC schedule. How a held deposit appears in the current balance varies by bank.

On Tuesday evening the app shows a current balance of $1,074 but an available balance of only $224. If Jordan pays a $400 bill that night based on the bigger number, the payment is either declined or overdraws the account. By Thursday, with the hold gone and the check released, the two numbers match again.

How overdraft decisions use the available balance

The CFPB's Circular 2022-06 explains why this matters for fees. Some institutions assess overdraft fees at settlement based on the available balance reduced by debit holds, not the ledger balance. That produces what the CFPB calls authorize positive, settle negative transactions: a card purchase approved when there was enough money, which later settles against a negative balance because another transaction posted first. The circular's example is a $50 card purchase authorized against a $100 balance; a $120 ACH debit settles first, and the card purchase then settles against the negative balance and triggers a fee. The CFPB says the delay between authorization and settlement is generally not of the consumer's own making.

The two banks this site covers handle the gap differently. Capital One's 360 Checking disclosures list three overdraft options, Auto-Decline (the default), Free Savings Transfer and No-Fee Overdraft, and say none of them carries a fee. Its posting-order section says that each time you use a debit card it may place a hold on a corresponding amount, and that another transaction may post while the original purchase is still pending. Ally's deposit agreement describes CoverDraft, which may approve qualifying overdrafts up to a limit, and says the CoverDraft limit is not included in the available balance. Ally also warns that a restaurant tip added after authorization can push the account further negative than the limit.

Checklist: keep the two numbers from surprising you

  • Budget from the available balance, then subtract any authorization you know is inflated (hotel, rental car, pump) until it drops.
  • After a check deposit, look for the hold notice or check your bank's availability page; the first $275 is the most you should count on the next business day unless your bank is faster.
  • Avoid scheduling autopays for the day after a large check deposit; give the check two business days, or longer if it is over $6,725 or the account is under 30 days old.
  • Use a credit card, not a debit card, for hotel and car-rental deposits if you want to keep checking-account money free.
  • Read your account agreement's overdraft section to learn whether it decides on the available balance, and pick a decline or transfer option if you would rather have a declined card than a negative balance.
  • If a pending charge never posts and the hold does not drop after the period your bank states, contact the bank with the merchant name and date.

Questions before you decide

Why did my available balance drop by more than I spent at the gas pump?

Pay-at-the-pump and some other merchants request an authorization before the final amount is known. Capital One lists a pay-at-the-pump authorization and hotel or car-rental incidental estimates among the reasons a pending amount differs from what finally posts. Ally says a preauthorization amount may be greater than the actual purchase and the hold may remain up to three business days after the transaction has been paid.

How long can a bank hold a check I deposit?

Under Regulation CC the general rule is that the first $275 of a day's check deposits must be available the next business day and the rest of a local check by the second business day. Exceptions allow longer holds, for example for new accounts, deposits over $6,725 in a day, redeposited checks, repeated overdrafts or reasonable doubt about collection. The dollar figures took effect July 1, 2025.

Which balance does my bank use to decide whether I overdrew?

It depends on the bank. A CFPB circular describes institutions that assess overdraft fees at settlement based on the available balance reduced by debit holds, which can charge a fee on a card purchase that was approved against a positive balance. Capital One says its overdraft options carry no fee, and Ally says its CoverDraft limit is not counted in the available balance; check your own account agreement.

Does a mobile check deposit follow the same hold rules?

Not always. Ally's deposit agreement says eligible checks deposited with Ally eCheck Deposit are not subject to Regulation CC funds availability requirements, although Ally may generally make them available within its listed timeframes. Capital One says mobile-deposited checks will generally be available on the first business day after the deposit date. Read your bank's policy before relying on mobile funds.
