The Costs of a $1,000 Cash Advance

• Cash advance fee: The fee for a $1,000 cash advance would be $38.4, based on the current average cash advance fee. But it could be even higher, depending on the card. Some credit card companies charge a 3% fee, while others charge up to 5%. Keep in mind that you’ll most likely have to pay a fee every time you take out a cash advance.
  
  There are some exceptions, however. The PenFed Platinum Rewards Visa Signature® Card, for instance, has a 0% cash advance fee.
• Cash advance APR: The cash advance APR for this amount would be around 6 cents per day at the current average cash advance APR of 22.53%. Keep in mind that interest will start accruing from the moment you perform the withdrawal. Plus, the interest you’re charged one day also becomes part of the balance accruing interest the next. In other words, credit card interest compounds daily.
• Other costs: There might also be ATM fees in case you use one that’s not affiliated with your card’s issuer. Banks typically charge non-customers $1.50 to $3.50 at their ATMs, but non-bank ATM operators often charge more, up to $10 per transaction.

As you can see, cash advances are very expensive transactions. So, it's best to avoid them unless it's an emergency. In case you must get one, make sure pay it off as soon as possible.
