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.
San Francisco has surpassed NY as the city with the most expensive rates, where the average babysitting rate for one child is $15.93 per hour. Denver has the least expensive rates, where the average pay starts at $11.04 an hour for one child.
