I stumbled upon Salary.com's Mom Salary.com calculator and created a paycheck for myself based upon the number of children I have and the hours I put in each week teaching, cooking, and cleaning. The check was for $167,000.00.
As you can see, they put my annual pay all in one paycheck. Slightly inconvenient, I think, but I won't complain.
Also, interesting to find that I would earn slightly higher than the national average, $138,005, for stay at home mothers. This is most likely because I have slightly higher than the national average number of children.
