How Kansas calculates child support
Kansas uses the income shares model. The schedule for the number of children gives an amount for each child by the parents' combined monthly income and the child's age group (birth to five, six to eleven, twelve and older); the amounts are added and each parent is responsible for their share of the total.
Gross income from almost all sources counts, before taxes; public assistance does not. Child support paid for other children is subtracted. Spousal maintenance paid is subtracted and maintenance received is added, increased by 25% for orders entered after the federal tax change if the parties agree.
When the children spend 35% or more of their time with the other parent (about 128 overnights a year), that parent's share is reduced by 10%, 20% or 30%. With equal time the Shared Expense Formula splits the difference between the parents' shares; the Direct Expense Formula adds a percentage of the gross obligation for the parent who doesn't pay the children's direct expenses.
The court must consider the paying parent's ability to pay: the federal poverty guideline for one person is subtracted from that parent's income, and when what remains is less than the support amount the court decides the amount. The estimate shows what remains.
The children's health insurance premium and work-related child care, after the child care tax credit, are added and shared by income; the parent who pays each cost is credited.
Child support paid under other orders is subtracted from income. When the parent without primary residency has other children living with them, the schedule for the total number of children that parent supports is used.
The schedules run to $18,000 of combined income a month. Above that, amounts are at the court's discretion; this estimate uses the extended formula printed with the schedules.
Income shares are rounded to the nearest tenth of a percent, combined income to the nearest schedule row, and every amount to the nearest dollar.
Parenting time in Kansas

When does child support end in Kansas?
Kansas support ends at 18. If the child is still in high school, it continues to June 30 of that school year, and on motion a court may continue it through the school year in which the child turns 19 when the parents agreed to the delay in finishing school. Support beyond that, for college or for an adult child with a disability, requires the parents' written agreement approved by the court.
