If i took out 150 from a credit card 2 weeks before the end of the month, will they charge interest that month

Question

I choose paying the bill at the end of the month, so they probably will charge interest that month and the next month that I wait to pay back. My interest is 10%

Answer 1

It depends on the credit card. Most charge interest on cash advances from the day you take the advance. Some don't. Some charge a fee, but don't charge interest that pay period.
If you pay the bill in full that first includes the advance, you should only be charged interest for that first half month.

Answer 2

sounds like you took a cash advance....there is no grace period on cash advances and the interest is MUCH higher and starts accruing immediately......
