My hours are 7am-5pm. Say drop off is 7am, school starts 8:30, pick up is 5pm school pick up is 3pm. Also depends on if you are serving breakfast, and afternoon snack and how much crafts/supplies you need for child as well as your time and energy walking in inclement weather to pick them up, and possibly wake babies from their naps.

Most people in my area charge $15 for before OR afterschool but $25 for BOTH.
