Cash Advance

A credit card cash advance is a withdrawal of cash against the card's credit line, at an ATM, a bank, or through the app, and it is the most expensive product the card sells. The fee is 5% of the amount or $10, whichever is greater. The interest starts the same day at a rate often 3 to 5 points above the purchase APR, and the grace period never applies. A $500 advance at a 26% advance APR carries the $25 fee and roughly $0.36 a day of interest from the first dollar.

The advance also skips the payoff order: payments apply to purchases first, then balance transfers, then cash advances last, so the advance balance sits and accrues while the cheaper balances clear. Convenience checks and peer-to-peer transfers through the card count as advances too, and the cash advance limit is a fraction of the credit line. The advance is the product to know about and never use, which is the whole entry.

The mechanics run at the machine or the app. Withdraw $500 at an ATM: the 5% fee, $25, posts immediately; the ATM owner's fee, $3 to $5, stacks on top; and interest accrues from day one at the advance APR, roughly $0.36 a day at 26%. Six weeks of carry costs the $25 fee, the ATM fee, and roughly $15 of interest on a $500 withdrawal.

The payment order is the trap. Card payments apply to the promotional balances first, then purchases, then cash advances last, per the CARD Act's allocation rule; the advance balance sits at its high rate while the cheaper balances clear. The advance also has its own limit, often 20% to 30% of the credit line, and the transactions that count as advances include convenience checks, wire transfers, and some peer-to-peer payments through the card.

The alternatives are the checking account, the debit card, and the emergency fund. A $500 withdrawal from a checking account costs the ATM fee and nothing else; the same $500 as an advance costs $25 plus interest from the first dollar. The emergency fund is the product the advance is impersonating, and the emergency fund is the account that makes the advance unnecessary. The advance is the product to know and never use.

The advance is the most expensive money in personal finance after the payday loan, and it is the product the card markets least because the margin does not need marketing. The fee, the rate, and the payment order are the three mechanics, and the payment order is the one that surprises. The grace period never applies, which is the detail most cardholders meet once.

I watched a colleague named Brent (yes, that Brent) take an $800 advance at an airport ATM for a deposit, pay the minimum for two months, and watch the advance balance sit at the advance rate while the payments cleared his purchases first, per the allocation rule. The $800 deposit cost the $40 fee, the ATM fee, and roughly $35 of interest. The checking account was the alternative he skipped.

The highest-leverage thing most Americans can do is never use the advance and build the emergency fund that makes it unnecessary. Read the fund mechanics in the emergency fund entry, price the carry in the credit card APR entry, and check the payoff order in the balance transfer entry.
