A cash advance is a facility bundled with your credit card that allows you to withdraw cash from ATMs both locally and overseas.
There are fees and interest charges associated with a cash advance. Every cash advance you take will be subject to an upfront service fee (see Cash Advance Fee), which is typically 6% of the amount withdrawn, or S$15, whichever is higher. Also, the interest charged on your cash advance will be higher than the base interest rate of your credit card.
The amount of cash advance you can take depends on your available credit limit, and is capped at up to 90% of your total credit limit.
A cash advance is granted on your credit card's available credit limit; it is separate from the funds you have in your bank account.
Not all credit cards have the cash advance facility enabled by default. Depending on your provider, you may have to make a separate application to enable your cash advance facility.
