A Cash Advance Starts Charging Interest Immediately

Taking cash out of an ATM with a credit card looks like an ordinary transaction, and the card does not warn you that it is a different product. A cash advance is priced under separate terms that make it far more expensive than a purchase.

The grace period does not apply

Purchases carry a grace period, which is the window between the statement closing and the due date during which no interest accrues if the balance is paid in full.

Cash advances are excluded from that protection. Interest begins accruing on the day the money leaves the machine and continues every day until that portion is cleared.

Paying the card in full at the next due date therefore still leaves interest owed, which arrives on the following statement and surprises people who believed they had paid everything.

There are three separate charges stacked together

The advance fee is taken upfront, usually as a percentage of the amount with a dollar minimum. On a small withdrawal that minimum can be a large share of the total.

The ATM operator may add its own fee, which is charged by the machine's owner rather than your card issuer and is a separate line on the statement.

The advance rate itself is typically higher than the purchase rate on the same card, and it is disclosed separately in the cardholder agreement.

Payments are applied where they help you least

When a card carries balances at different rates, issuers are generally required to apply anything above the minimum to the highest-rate balance first, which favors the advance.

The minimum payment itself, though, can be applied to the lowest-rate balance. If you pay only the minimum, the expensive advance can sit and accrue while purchases are cleared.

This is why an advance that felt small tends to persist. Paying it off requires deliberately paying well above the minimum until the advance portion is gone.

Several transactions count as advances without looking like it

Convenience checks mailed by an issuer are advances. So are wire transfers, money orders and loading a prepaid card, because the card network codes them as cash rather than purchases.

Some peer-to-peer payment apps are coded the same way when funded by a credit card, which is how an ordinary transfer to a friend acquires an advance fee.

The transaction type appears on the statement, so an unexpected fee can usually be traced to the coding rather than to an error.
