…I would say priceless but apparently there’s an actual figure…
NEW YORK (Reuters) – A full-time stay-at-home mother would earn $134,121 a year if paid for all her work, an amount similar to a top U.S. ad executive, a marketing director or a judge, according to a study released Wednesday.
A mother who works outside the home would earn an extra $85,876 annually on top of her actual wages for the work she does at home, according to the study by Waltham, Massachusetts-based compensation experts Salary.com [source]
Note that this is only for American mothers. This figure will probably adjust itself depending on the mother and her environment (country of origin) as well as inflation.
