What is the primary reason for avoiding cash advances on credit cards?

The primary reason for avoiding cash advances on credit cards is that they are often subject to higher fees and interest rates. When you take a cash advance, the credit card issuer typically charges a cash advance fee, which can be a percentage of the amount withdrawn or a fixed amount, whichever is higher. Additionally, the interest rates on cash advances are usually higher than those for standard purchases, and interest begins to accrue immediately without the benefit of a grace period. This combination of higher fees and immediate interest accumulation can lead to a significant increase in the overall cost of borrowing, making cash advances a less favorable option compared to regular credit card transactions.
