WISCONSIN CHILD SUPPORT CALCULATION WORKSHEET
Case number: [NUMBER] Court and county: [COURT, COUNTY]
Parent A: [NAME] Parent B: [NAME]
Children covered by this calculation: [NAMES OR COURT-APPROVED IDENTIFIERS]
Calculation date: [DATE] Income period used: [DATES]
1. Select the applicable calculation
The amounts below use monthly income available for child support as determined under DCF 150.03, with any applicable special rules under DCF 150.04. Record the source of each amount. Do not subtract an expense or prior support order a second time if it is already reflected in the income input.
| Input | Parent A | Parent B |
|---|---|---|
| Monthly income available for child support | $[AMOUNT] | $[AMOUNT] |
| Source and date of income evidence | [SOURCE] | [SOURCE] |
| Court-ordered placement, overnights or equivalent care per year | [NUMBER] | [NUMBER] |
| Percentage of total court-ordered placement | [PERCENT] | [PERCENT] |
Applicable route: ☐ Nonshared placement, section 2 ☐ Shared placement, section 3 ☐ Special circumstance, section 4.
A shared-placement calculation under DCF 150.035(1) requires both parents to have at least 25% or 92 days of court-ordered placement and both to be ordered to assume basic support costs in proportion to placement. Record the order and facts supporting those conditions: [DETAILS]. If the conditions are not met, use section 2 or the applicable special rule.
2. Nonshared placement calculation — DCF 150.035(2)
Payer: [PARENT A / PARENT B] Number of children: [NUMBER]
| Number of children | Designated percentage |
|---|---|
| 1 | 17% |
| 2 | 25% |
| 3 | 29% |
| 4 | 31% |
| 5 or more | 34% |
Payer's monthly income available for child support: $[AMOUNT]
Applicable designated percentage: [PERCENT]
Monthly amount before any special rule or court-approved deviation: $[INCOME] × [PERCENT] = $[AMOUNT]
3. Shared placement calculation — DCF 150.035(1)(b)
Complete one column for each parent. The placement percentage used in row 4 is the other parent's share.
| Calculation step | Parent A | Parent B |
|---|---|---|
| 1. Monthly income available for child support | $[AMOUNT] | $[AMOUNT] |
| 2. Row 1 × designated percentage for number of children | $[AMOUNT] | $[AMOUNT] |
| 3. Row 2 × 150% | $[AMOUNT] | $[AMOUNT] |
| 4. Row 3 × other parent's placement percentage | $[AMOUNT] | $[AMOUNT] |
Offset: [LARGER ROW 4 AMOUNT] − [SMALLER ROW 4 AMOUNT] = $[AMOUNT].
Parent with larger row 4 obligation: [PARENT]. Lesser of the offset or that parent's designated-percentage amount: $[AMOUNT]. This is the proposed monthly base payment before any applicable special rule or court-approved deviation.
Variable costs: Itemize the children's variable costs, each parent's proposed share, and the supporting records separately. DCF 150.035(1)(b)6 addresses these costs in addition to the base obligation.
| Variable cost and evidence | Monthly amount | Parent A proposed share | Parent B proposed share |
|---|---|---|---|
| [DESCRIPTION] | $[AMOUNT] | $[AMOUNT] | $[AMOUNT] |
| [DESCRIPTION] | $[AMOUNT] | $[AMOUNT] | $[AMOUNT] |
4. Special circumstances and requested deviation
Special rule applicable under DCF 150.04: ☐ Serial-family parent ☐ Split placement ☐ High-income payer ☐ Low-income payer ☐ Other [SPECIFY] ☐ None. Identify the subsection, supporting facts, and attached calculation: [DETAILS OR NONE].
Deviation from the standard requested under Wis. Stat. § 767.511(1m): ☐ No ☐ Yes. If yes, state the standard amount, requested amount, and facts supporting the request: [DETAILS].
5. Health care expenses and proposed amount
The court assigns responsibility for the child's health care expenses under Wis. Stat. § 767.513(2). Record the insurance and uncovered-cost proposal separately from the base calculation.
| Expense or coverage | Parent A | Parent B | Supporting record |
|---|---|---|---|
| Child's share of health insurance premium | $[AMOUNT] | $[AMOUNT] | [SOURCE] |
| Uncovered health care expenses | $[AMOUNT] | $[AMOUNT] | [SOURCE] |
Proposed base child support: $[AMOUNT] per month, payable by [PARENT] to [PARENT].
Proposed separate variable-cost and health-expense allocation: [DETAILS].

Family law covers the paperwork that shapes divorce, custody, child support, adoption, guardianship, and other family matters. These filings are emotional and high-stakes, and they also have to meet strict procedural rules for service, financial disclosure, and parenting plans. Clean, accurate paperwork keeps the focus on getting a workable outcome for the family instead of getting derailed by technical problems that delay hearings or force amended filings.
