How is child support calculated?

Texas family law sets the following general guidelines for calculating child support. Child support using these guidelines is called “guideline child support.” The percentages below are of the noncustodial parent’s average monthly net resources:

1 child = 20%

2 children = 25%

3 children = 30% 

4 children = 35%

5 children = 40%

6 or more children = not less than 40%

Note that the noncustodial parent is given credit for the amount they are paying in medical and dental insurance, or in cash medical and dental support, whichever the case may be.

If you have more than one child together, the amount of child support will be ordered to “step down” as child support ends for each child (when the oldest child turns 18 and graduates from high school).

Visit the Texas Attorney General Child Support Calculator to calculate your guideline child support.

Remember that guideline child support changes if the noncustodial parent has other children.
