How the number of children changes the amount in Montana
With Parent A earning $60,000 and Parent B $40,000, the guideline amount for 5 children is $1,320 a month, about 2.21 times the $598 for one child. Support rises with each child, but by less than the first child's amount, because the guidelines reflect how households share costs among children.
Montana uses a Melson-type formula on yearly amounts. Each parent keeps a personal allowance of $20,748. The children's primary allowance ($6,224 a year for one child) and their expenses are shared by the parents' incomes above the allowance; a standard of living adjustment then adds a share of each parent's remaining income.
