Montana Child Support Calculator – Accurate & Easy to Use

What Is the Montana Child Support Calculator?

The Montana Child Support Calculator estimates how much one parent may need to pay the other to help cover the cost of raising their children.

It uses the same basic formulas outlined by the Montana Department of Public Health and Human Services (DPHHS). The calculator looks at both parents’ incomes, deductions, and shared expenses, then applies the Montana child support schedule to determine a fair payment.

It’s important to note:

The calculator provides an estimate only. The final child support amount can vary based on your exact circumstances and court decisions.

How the Montana Child Support Calculator Works

The calculator uses a step-by-step formula to estimate child support. Here’s how it breaks down:

1. Parent Incomes

You’ll start by entering each parent’s gross monthly income.
This includes wages, salaries, bonuses, and any other sources of income.

Example:

• Parent A earns $4,000 per month
• Parent B earns $2,500 per month

Then, you can enter any allowable deductions (like taxes, health insurance, or mandatory retirement contributions). These amounts are subtracted to find each parent’s available income.

2. Number of Children

Next, you’ll select how many children are covered by the support order.
The calculator uses a predefined schedule from the Montana child support guidelines that lists estimated monthly costs per child based on total household income.

3. Parenting Time (Overnights)

Parenting time affects how much support one parent pays.
You’ll enter how many overnights per year the children spend with Parent B (the non-primary parent). The calculator automatically adjusts based on shared parenting time:

• If both parents have more than 110 overnights, it treats the case as joint custody.
• If one parent has fewer than 110 overnights, it’s considered primary custody, and that parent typically pays support.

4. Additional Expenses

You can also enter other child-related expenses, such as:

• Children’s health insurance premiums
• Work-related child care costs

These are added to the total monthly obligation and shared between parents according to their income percentages.

5. Final Estimate

The calculator combines all these details to show an estimated monthly payment.
It clearly states who is likely to pay whom — for example:

“Estimated Payment from Parent B to Parent A: $428 per month.”

You’ll see the result instantly after clicking “Calculate.”

Example Scenario

Let’s take a simple example to see how it works:

In this case:

• The calculator finds the combined available income ($6,500).
• Refers to the Montana guideline schedule for 2 children.
• Adjusts based on income share and parenting time.
• Outputs the estimated child support payment (e.g., ~$520/month from Parent B to Parent A).

Important Notes and Legal Disclaimer

While the Montana Child Support Calculator is built around the state’s guideline formula, it’s still for informational purposes only.

Final child support amounts may differ based on:

• Each parent’s verified income
• Medical or educational needs of the child
• Custody arrangements
• Other court-approved adjustments

Always consult a Montana family law attorney or your local Child Support Enforcement Division (CSED) for personalized legal guidance.
