Formula
Advisory: 30% of payer’s gross minus 50% of recipient’s gross (28% / 58% with child support)
The Statewide Alimony Guideline Committee’s worksheet (revised 2006) suggests 30% of the payer’s gross monthly income minus 50% of the recipient’s (28% minus 58% when child support is paid between the parties); it is endorsed for settlement purposes only and does not bind judges.[2]
