How Oregon calculates child support
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.
Each parent keeps a self-support reserve of $1,729 a month (130% of the federal poverty guideline for one person), and their share of support can't exceed the income above it. Unless an exception applies, the paying parent's total support is at least $100 a month.
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.
Other children a parent lives with or is ordered to support reduce that parent's income by their share of the scale amount for all of the parent's children.
The scale runs to $30,000 of combined adjusted income a month; above that the top amount applies, and a court may deviate.
Income shares and parenting time credits are rounded to a hundredth of a percent, worksheet amounts to the cent and the guideline amount to the nearest dollar.
