Parents & Children

We’ll start with some basic information about the parents and kids involved in this case.

Parent A name

Parent B name

Number of children covered by this order

Case county (optional)

You can use “Parent A / Parent B” instead of Mother/Father if that fits your case better. These labels will appear on the summary and worksheets.

Income – W-2 Style

Enter annual income for each parent. You can add up all W-2s and other income types. Use the same numbers you’d get from tax forms.

Parent A income (annual)

W-2 Box 1 – wages, tips, other compensation (all jobs) Self-employment net (Schedule C/F, etc.)

Other taxable income (interest, unemployment, etc.) Other nontaxable income (if counted under guidelines)

Parent B income (annual)

W-2 Box 1 – wages, tips, other compensation (all jobs) Self-employment net (Schedule C/F, etc.)

Other taxable income Other nontaxable income

Tip: To annualize, multiply monthly amounts by 12, or weekly amounts by 52.

Deductions & Other Support

These are amounts that Montana’s guidelines allow you to subtract from income (taxes, mandatory retirement, support for other children, etc.).

Parent A deductions (annual)

Federal income tax withheld State income tax

Social Security tax (FICA) Medicare tax

Mandatory retirement contributions Union dues

Child support paid for other children (court-ordered) Alimony paid

Parent B deductions (annual)

Federal income tax withheld State income tax

Social Security tax (FICA) Medicare tax

Mandatory retirement contributions Union dues

Child support paid for other children (court-ordered) Alimony paid

Use annual totals. You may need to convert from paystub “year-to-date” amounts.

Child-Related Costs

These are costs for the children in this case only. The calculator will split them between parents.

Work-related childcare (annual, total for these children) Child health insurance premium (annual portion for these children)

Uninsured medical / therapy (annual) Other recurring child expenses (annual)

Do not include costs already counted elsewhere (like adult health insurance or unrelated debt).

Parenting Time

Enter the approximate number of days per year each child spends with each parent. If parenting time is the same for all children, you can use one set of numbers.

Days per year with Parent A (each child, if roughly the same) Days per year with Parent B (each child)

If either parent has more than 110 days per year with a child, Worksheet B’s shared-parenting adjustment may apply. This tool approximates that adjustment.
