There are 2 methods of calculating child support that are generally used. First, is guideline child support. Guideline child support is a percentage of the obligor’s income based on the number of children before the court and the number of children not before the court, but that the obligor is responsible for supporting financially. Second, non-guideline support is when the court considers the income of each parent, the number of children, and the amount of time the child spends with each parent. It is important to note that which method is used is at the Judge’s discretion. Therefore, it is important to present evidence to the court regarding why the method you want used is in the best interest of the child.
The Texas Attorney General has a calculator on it’s website to assist you with guideline child support. You can check it out here: https://csapps.oag.texas.gov/monthly-child-support-calculator.
