Minnesota Child Support Calculator
Estimate your monthly child support obligation under Minn. Stat. § 518A.35. Enter your numbers below for an instant estimate with a step-by-step breakdown and statute citations.
What You'll Need
Gather these four figures first for an accurate Minnesota estimate:
- Each parent's gross monthly income — recent pay stubs and last year's tax return are the best source.
- Number of children covered by the order.
- Parenting time — roughly how many overnights per year the child spends with each parent.
- Monthly health insurance and childcare costs for the children.
Minnesota Child Support Calculator
This state uses the Income Shares model, which considers both parents' income to determine a combined obligation, then splits it proportionally.

How Minnesota Calculates Child Support
Minnesota determines child support using the Income Shares Model, the standard set out in Minn. Stat. § 518A.35. Under this model, the incomes of both parents are combined to estimate what they would have spent on the children if the family were intact, and that total obligation is then divided between them in proportion to each parent's share of the combined income.
The calculator above applies that formula to the income and expense figures you enter and shows each step of the math, so you can see exactly how the estimate is built. Because every order ultimately runs through a judge, the guideline figure is a starting point rather than a guaranteed result — the sections below explain what goes into it and where real orders can differ.
Key Rules Behind the Minnesota Formula
- Minnesota's guidelines run on ADJUSTED GROSS income: income taxes and FICA are never subtracted. The only adjustments to gross income are items like court-ordered child support or maintenance a parent actually pays for other cases. Enter income before taxes.
- Minnesota uses the Income Shares model under Minn. Stat. § 518A.35, combining both parents' parental income for child support (PICS) to determine the basic child support obligation.
- The basic obligation is taken from the statutory guidelines table (Minn. Stat. § 518A.35) and prorated between parents based on each parent's share of combined PICS.
- Minnesota uses three parenting time categories: less than 10% (no adjustment), 10-45% (moderate adjustment), and 45.1%+ (~146 overnights — full parenting expense adjustment).
- Health insurance premiums (medical support), work-related childcare costs, and unreimbursed medical expenses are added to the basic obligation and divided proportionally between parents.
- Parental income for child support (PICS) is calculated from gross income minus certain deductions including taxes, Social Security, union dues, and pre-existing support obligations (Minn. Stat. § 518A.29).
- Courts may deviate from the guidelines upon a written finding that the guidelines amount would be unjust or inappropriate under the circumstances (Minn. Stat. § 518A.43).
- Minnesota requires both parents to provide medical support (health insurance or a cash equivalent) for children in addition to basic child support.
What Counts as Income
Child support guidelines are built on each parent's income, so the figure you enter matters more than any other input. Most states start from a broad definition of gross income that includes wages, salary, tips, commissions, bonuses, self-employment earnings, and many forms of government benefits, then subtract specific deductions to reach the income the formula actually uses.
Minnesota's rules under Minn. Stat. § 518A.35 spell out which deductions apply and whether the formula runs on gross or net income. The calculator's field labels tell you which figure to enter; when in doubt, use your most recent pay stubs and tax return, and confirm the details in the Minnesota child support laws guide.
How to Establish a Child Support Order in Minnesota
A child support obligation becomes enforceable only once a court or the state child support agency issues an order. Either parent can request one, and in Minnesota, as in every state, the local child support agency that operates under the federal Title IV-D program can open a case, locate the other parent, establish paternity if needed, and ask the court to set support using the guideline formula.
When you apply, expect to provide proof of income for both parents, the child's information, and details about health insurance and childcare costs — the same inputs this calculator uses. Running your numbers here first gives you a realistic idea of the order amount before you file.

Important Legal Disclaimer
This calculator provides an estimate only based on Minnesota's child support guidelines. Actual court-ordered amounts may differ based on factors not captured here, including special needs, shared custody arrangements, travel costs, and judicial discretion.
This is not legal advice. Consult a family law attorney for guidance specific to your situation.
How to Modify a Minnesota Child Support Order
Child support orders are not permanent. Minnesota courts can revisit an order when there has been a substantial change in circumstances — for example, a significant change in either parent's income, a change in custody or parenting time, or a meaningful change in the child's needs. Federal rules also entitle parents in IV-D cases to request a review periodically (often about every three years) even without a major change.
To estimate a new amount, re-run the calculator with the updated figures. If the guideline result is meaningfully different from your current order, that gap is often what supports a modification request — though only a court can actually change the order.
How Child Support Is Enforced in Minnesota
Once an order is in place, Minnesota has strong tools to collect it. The most common is income withholding: federal law requires most new orders to be paid through automatic wage garnishment, so payments are deducted from the paying parent's paycheck. When payments fall behind, enforcement can escalate to intercepting tax refunds, suspending driver's or professional licenses, placing liens on property, reporting the debt to credit bureaus, and, in serious cases, contempt-of-court proceedings.
Interest and penalties can accrue on unpaid support, so an order that goes unaddressed tends to grow rather than disappear. If your circumstances have changed, seeking a modification through the court is almost always better than simply paying less than the order requires.
Frequently Asked Questions
Is this Minnesota child support calculator accurate?
It applies the official Minnesota guideline formula from Minn. Stat. § 518A.35 to the numbers you enter, so it gives a close estimate of a typical guideline order. It is not an official court calculation — a judge can order a different amount based on the specific facts of your case.
Can a judge order a different amount than the calculator shows?
Yes. The guideline figure is a presumptive starting point, but Minnesota courts can deviate up or down when the standard amount would be unfair — for example, because of extraordinary medical or educational expenses, a child's special needs, or other obligations. The order the judge signs controls.
What income do I enter into the Minnesota calculator?
Use the figures described by each field's label — generally your regular income from work and other sources. Minnesota's guidelines define exactly which income counts and which deductions apply, so your most recent pay stubs and tax return are the best source for accurate numbers.
Is child support taxable in Minnesota?
No. Under federal tax law, child support is not taxable income for the parent who receives it and is not tax-deductible for the parent who pays it. This is different from spousal support and does not change from state to state.
How long does child support last in Minnesota?
In most cases child support continues until the child reaches the age of majority or finishes high school, but orders can extend longer — for instance, for a child with a disability. Check the Minnesota child support laws guide for the specific rules that apply to your situation.
Disclaimer
This calculator provides estimates only and is not a substitute for legal advice. The actual amount ordered by a Minnesota court may differ based on factors including but not limited to: the special needs of the child, travel expenses for visitation, extraordinary educational or medical expenses, the parents' other support obligations, and the court's discretion to deviate from the guidelines. For advice about your specific situation, consult a licensed Minnesota family law attorney.
