Massachusetts laws ...the amount of alimony should generally not exceed the recipient's need or 30 to 35% of the difference between the parties' gross incomes established at the time of the order being issued.
The Massachusetts Supreme Judicial Court took a novel approach and determined that the alimony law and the child support guidelines allow the court to consider awarding both alimony and child support based on the same income.
40% of the high earner's net monthly income minus 50% of the low earner's net monthly income. For instance, if Spouse A earns $5,000 per month and Spouse B earns $2,500 per month, temporary spousal support might be calculated as follows: 40% of $5,000 = $2,000. 50% of $2,500 = $1,250.
