At midnight each night your AdultWork.com credits account will be debited based on the number of categories you have chosen. You will be debited 1.00 credit(s) for your first category and 0.10 credits for each one chosen after that.

For example:

If you choose two categories you will be charged 1.00 + 0.10 = 1.10 credits.

If you chose four categories you will be charged 1.00 + 0.10 + 0.10 + 0.10 = 1.30 credits.

You must have sufficient credits to cover all of your category selections, otherwise you will not be debited and your profile will not appear.  If you deselect categories you will not be refunded for the remaining portion of the day, although if your total number of categories goes above what you've been charged for, you will be debited within 20 minutes.  (This time lag gives you the opportunity to change categories without being charged.)

Members that are featuring their profiles will not be charged on the days that their profile is featured for.

Your chosen categories and credits balance are evaluated every 20 minutes.  When changing your categories or adding to your balance it can take up to 20 minutes for your profile to re-appear.

In summary, you will be charged at around midnight every day when a charge is required, except on your first day or when your profile first becomes valid for display, (has a summary, and some other details), when you will be charged within 20 minutes.  (This saves you from having to wait until midnight to appear on the Site.)
