If you want an inexperienced nanny, you could get one for under $15 an hour, mid range nanny is going to be around $15-17 an hour. If you want someone who has a lot of experience, and/or education, you are looking at $17-22 an hour. If your nanny works more than 40 hours a week, you also have to pay overtime. You also have to think about what benefits you want to give to the person. Sick days, vacation, holidays, do you give health insurance or pay part of it, car to use while nanny is taking care of child, etc..etc..
