How to Use the Kansas Child Support Calculator
Enter what you know and press Calculate Estimate. The calculator follows the Kansas Child Support Guidelines effective July 1, 2025 and the Kansas Child Support Worksheet.
- Enter each parent's gross monthly income (domestic gross income) before taxes.
- Enter how many children are in each age group: 0-5, 6-11 and 12-18. Kansas uses the age on the child's nearest birthday.
- Choose the parent who has primary residency (the children live with most of the time).
- Enter the overnights a year with the other parent, or tick equal parenting time.
- Add the children's health and dental insurance premium and work-related child care (after the expected child care tax credit), and say who pays them.
Your numbers are sent with the form, not placed in the page address, and this site does not store them. This is a planning estimate. A Kansas judge or hearing officer sets the actual amount.
Kansas Child Support Guidelines in 2026
Looking for the Kansas child support guidelines for 2026? The current guidelines took effect July 1, 2025 under Supreme Court Administrative Order 2025-RL-121. That order changed the rules on requests for financial information, income computation and judgments. The child support schedules and the calculation steps are the ones adopted with the August 1, 2024 guidelines. We found no newer guidelines for 2026.
New guidelines do not change an existing order. Support based on earlier guidelines stays in effect until a judge issues a new order.
How Kansas Calculates Child Support
Kansas uses an income shares model on gross income, following the lines of the child support worksheet:
- D.1-D.3: add both parents' child support income and find each parent's percentage.
- D.4: in the schedule for the total number of children, find the amount for each child's age group at the combined income and add them up.
- D.5: multiply by each parent's percentage.
- E-I: subtract any parenting time adjustment, add each parent's share of insurance and child care, and credit the parent who pays them.
- K-L: apply adjustments and the ability to pay test. The result for the parent without primary residency is the presumed support amount.
The Kansas Child Support Schedules
The schedules give an amount per child by combined monthly income, family size and age group. Sample rows:
| Combined gross income | 1 child, 0-5 | 1 child, 6-11 | 1 child, 12-18 | 2 children, 0-5 (each) | 2 children, 6-11 (each) | 2 children, 12-18 (each) |
|---|
| $3,000 | $547 | $612 | $651 | $435 | $487 | $518 |
| $5,000 | $808 | $904 | $961 | $626 | $701 | $746 |
| $8,000 | $1,156 | $1,294 | $1,376 | $876 | $980 | $1,042 |
| $10,000 | $1,371 | $1,534 | $1,632 | $1,027 | $1,149 | $1,222 |
| $15,000 | $1,868 | $2,090 | $2,223 | $1,371 | $1,534 | $1,632 |
The schedules run from $50 to $18,000 a month and cover one to six children. Income between rows is rounded to the nearest row. The 0-5 and 6-11 amounts are 84% and 94% of the 12-18 amount. Above $18,000 each schedule gives an extended formula (income raised to the power .6386 times a family-size factor), which the court may use.
Parenting Time Adjustment and Equal Parenting Time
If the children spend 35% or more of their time with the parent not having primary residency, the court may reduce that parent's share (section IV.H.2). Time at school or day care is not counted.
| Time with the parent not having primary residency | Adjustment |
|---|
| 35%-39% (about 128-145 overnights) | 10% |
| 40%-44% (about 146-164 overnights) | 20% |
| 45%-49% (about 165-182 overnights) | 30% |
Equal parenting time: the court may use the Direct Expense Formula: half the difference between the parents' proportionate shares, plus 7% (combined income up to $4,690), 10.5% (above $4,690 and below $8,125) or 15% ($8,125 or more) of the gross obligation, paid by the parent who does not pay the children's direct expenses. Parents with a written shared expense plan use only the first part.
Kansas Child Support Examples
In each example Parent B has primary residency. Amounts are monthly and come from this calculator.
Example 1: One child age 6-11
A earns $5,000 and B earns $3,000 ($8,000 combined). The one-child schedule gives $1,294, and A's 62.5% share is $809 a month.
Example 2: Two children with insurance and child care
A earns $6,000 and B earns $4,000. One child is 0-5 and one is 12-18, so the gross obligation is $2,249. B pays $500 child care and $200 insurance. A pays $1,349 plus 60% of $700 = $1,769 a month.
Example 3: Parenting time adjustment
A earns $7,000 and B earns $3,000, one child age 6-11, 150 overnights with A (41.1%). A's $1,074 share is reduced by 20%: $859 a month.
Example 4: Equal parenting time
A earns $7,000 and B earns $5,000, two children age 6-11, equal time, B pays direct expenses. A pays half the $434 difference ($217) plus 15% of $2,616 ($392): $609 a month.
