How it Works in Montana

Child support in Montana is calculated using the Income Shares Model, which is the most common method in the U.S. The formula considers both parents' gross monthly incomes to determine the basic support obligation. Adjustments are then made for factors like healthcare premiums, childcare costs, and the amount of time the child spends with each parent. Our calculator simplifies this by guiding you through each necessary input.

2025 Guideline Updates

For 2025, Montana continues to refine its child support guidelines to ensure fairness and accuracy. While there are no major legislative overhauls announced, the economic data used to set the basic support obligations is periodically updated to reflect cost of living changes. Always check for the most current local court rules, as they can influence the final calculation.
