How much does a Chase cash advance cost?

A Chase cash advance generally costs: Either $10 or 5% of the amount of each transaction, whichever is greater. Some exceptions are certain Chase’s business credit cards, as well as some co-branded cards. Moreover, interest begins accruing on a cash advance immediately; the Chase cash advance APR is 25.74% (V) for most cards, which is a lot higher than each card’s regular APR.

Here's what you should know before getting a chase cash advance:

• Chase Cash Advance Fee: Either $10 or 5% of the amount of each transaction, whichever is greater. This goes for the vast majority of the cards.
• Chase Cash Advance APR: 25.74% (V) for most Chase credit cards. This rate kicks in right when you withdraw the money.
• PIN: A PIN is required to get a Chase credit card cash advance at an ATM. You can call the number you see on the back of your card to request a PIN from Chase customer service.
• How to Do It: You use your Chase credit card like a debit card to get money from an ATM. Your cash advance balance is the amount you withdraw, plus the cash advance fee.
• Limits: Many cards have a separate cash advance limit, which is a portion of their overall credit limit. For example, while your limit might be $1,000, if your cash advance limit is 10%, you'll only be able to withdraw $100.

So, to put it simply, cash advances are expensive. You really should avoid them entirely unless you’re in an emergency situation and a cash advance is your only option. If you do have to make one, you can’t avoid the fee, but you can prevent a lot of the interest if you repay your balance right away. But you should also know that cash advances will look bad to your issuer, and could also hurt your chances of getting a credit limit increase in the future.

Cash advances are really expensive, and I'd advise against them. That being said, there's a fee of 3% to 5% of the amount of each transaction, with a minimum of $10. Also, the interest rate charged for cash advances can be anywhere between 19.49% and 25.24%.

You can get a Chase cash advance from any ATM or by going to a Chase Branch and asking for a cash advance. 
There will be hefty fees for that transaction and the interest rates are higher than for purchases. You want to use cash advance for extreme emergency. You are always better off using other cheaper alternatives.
