How It Works

Our calculator uses a simplified formula based on Montana’s statutory guidelines for calculating child support. It takes into account the incomes of both parents, the number of children, and additional child-related expenses to estimate the child support payment.

The formula is as follows:

Child Support = ((Income of Parent 1 + Income of Parent 2) / 2) – Monthly Expenses
