Work-related child care is shared by income share. The children's health coverage cost is shared in proportion to each parent's reasonable-cost limit: 4% of adjusted income, or nothing for a parent earning at or below the highest Oregon full-time minimum wage ($16.80 an hour). The parent who pays a cost gets credit for it.
How Oregon works it out
Oregon uses the income shares model: the obligation scale gives the basic support obligation for the parents' combined monthly adjusted income and number of children, and each parent is responsible for their percentage share.
Gross income from almost all sources counts. Spousal support owed to a parent is added; spousal support a parent owes, mandatory union dues and the cost of the parent's own health coverage are subtracted. Child support received and SNAP don't count. A court may treat a parent who could work as earning full-time minimum wage ($14.55 an hour); this estimate uses the incomes you enter.
Each parent gets a parenting time credit for their own overnights, from a formula that rises with every overnight; there is no threshold. The credit is a percentage of the basic obligation, reaching half of it at 182.5 overnights each. Only the parent with the larger net obligation pays.
