Unlike nannies, babysitters often work part-time or on an âas-neededâ basis for several families at a time, and are paid hourly at the end of a shift. Hourly rates are influenced by cost of living and minimum wage laws. According to a 2017 survey of Sittercity babysitters, the U.S. national average is $13.95/hour.
The average cost of a babysitter is $10 an hour, but a number of factors contribute to that wage. Be sure to consider these pointers before paying. A babysitter costs $10 an hour on average, but expect to pay an additional $2 to $4 per hour for each additional child. Itâs Saturday night and youâre ready to hit the town.
