3.01(A)A parent’s child support obligation consists of
(1) a base support obligation (§3.02) adjusted for parenting time (§3.03);
(2) medical support obligations that include ordinary and additional (extra-ordinary) medical expenses (§3.04), health care coverage and division of premiums (§3.05); and
(3) child care expense obligations (§3.06).
3.01(B)Generally, support obligations should be apportioned between the parents based on each parent’s percentage share of their combined net incomes.
(1) When figuring the percentage to use to apportion the base support obligation using the General Care Equation (§3.02(B)), only include a parent’s net income if it exceeds the Low Income Threshold (§2.09(A)), and round the resulting percentages to the nearest hundredth percent.
(2) The medical support and child care obligations’ percentages should be based on both parents’ net incomes and rounded to the nearest whole percent, but each parent’s share cannot be less than 10 percent or more than 90 percent.
