What is the child support calculation if I need to pay child support for two children, but I have a new baby at home?

Child support in Texas is calculated on the net resources of the person paying the support (the “obligor”), taking into account the cost of health insurance and how many children the obligor has a duty to support. For example, if there are two children, and he has a third child for whom he has a duty to support living with him, the calculation is 22.50% of the net resources. There are other factors that may need to be considered.
