It isn't quite as simple as taking the support obligation and then using that to calculate the income. As you may know, the calculation is don the other way, starting with the income and then arriving at support.
The Massachusetts guidelines take a variety of factors into consideration. These factors include the number of children, the ages of the children, the income of the custodial parent, costs of health insurance and, of course, the non-custodial parent's income.
Additionally, Massachusetts uses a percentage within its guidelines calculations as well. Massachusetts starts with a "basic order" as a starting point. According to the basic order percentages, a non-custodial parents obligation for one child should be between 21 and 25 percent of income. For two children, the range is 24 to 30 percent. For three children, it is 27 to 33 percent.
With all this in mind, and based on the information provided, it would be impossible to give a reliable calculation as to his income. Having said that, when the calculation was completed, you should have had his financial disclosure. This would include paystubs, tax returns and other documents that would have shown his income.
