If a stay-at-home mom could be compensated in dollars rather than personal satisfaction and unconditional love, she'd rake in nearly $117,000 a year.
That's according to a study by Salary.com, a Waltham, Mass.-based firm that studies workplace compensation.
The eighth annual survey calculated a mom's market value by studying pay levels for 10 job titles with duties performed by typical mothers, including housekeeper, teacher, psychologist and chief executive.
This year, the annual salary for a stay-at-home mom would be $116,805, and a mom who juggles an outside job would get $68,405 for her motherly duties.
The biggest driver of a mother's theoretical salary is the overtime pay she would receive.
The 18,000 mothers surveyed about their typical week reported working 94.4 hours -- meaning they'd be spending more than half their working hours on overtime.
Mothers who work outside the home reported an average 54.6-hour "mom workweek" besides the hours they spent at paying jobs.
