With child care and health insurance

Wisconsin's guideline amount doesn't add child care costs.

Monthly guideline amount for the example above with costs paid by Parent B.

Health insurance $150 a month$1,692 a month A→B
Health insurance $300 a month$1,692 a month A→B

Child care and health insurance aren’t added to the percentage amount. The court assigns health insurance and uninsured medical costs separately, and with shared placement it splits costs such as child care and tuition by each parent’s share of placement.

How Wisconsin works it out

Wisconsin sets child support as a percentage of the paying parent’s gross monthly income: 17% for one child, 25% for two, 29% for three, 31% for four and 34% for five or more. The other parent’s income doesn’t change the amount unless the parents share placement.

Income is gross income from all sources, taxable or not, divided by twelve for a monthly figure. Public assistance, Supplemental Security Income, food stamps and child support received are left out. Taxes aren’t deducted.

When each parent has the children at least 92 overnights a year, Wisconsin’s shared-placement formula applies: each parent’s income times the percentage, times 150%, times the share of time the children spend with the other parent. The two amounts are offset, and the paying parent never pays more than the plain percentage of their own income.
