How Maryland works it out
Maryland uses the income shares model: the schedule gives the basic child support obligation for the parents' combined monthly adjusted actual income, and each parent is responsible for their share.
Income from almost any source counts, before taxes. Support paid for other children and alimony paid are subtracted, and alimony between the parents in this case is added to the parent who receives it. Means-tested benefits such as SSI and SNAP don't count.
Shared physical custody applies when each parent has at least 92 overnights a year. The basic obligation is multiplied by 1.5 and divided by income share, and each parent's share is applied to the other parent's percentage of time. A parent with 92 to 109 overnights has their amount increased by 10% down to 2%. The parent owing more pays the difference, but no more than they would owe without shared custody.
