Care.com asserts that babysitters make an average of $10 per hour, so it may be acceptable to charge a family at this rate. However, you should raise or lower your price based on your experience.
You can also adjust your babysitting rate depending on the amount of children you'll be watching. You can charge $2 to $5 more per hour for each additional child in your care. Also, if you'll need to run errands for the family, such as taking a child to sports practice or a doctor's appointment, you can increase your rate. You can receive an additional $10 for each meal you have to prepare for the children.
