Child Support Calculation Worksheet

IMPORTANT: THIS IS A PREPARATION GUIDE — NOT THE OFFICIAL COURT WORKSHEET

Tennessee requires the use of the official Child Support Worksheet prescribed by DHS Rule 1240-02-04-.08 for child support calculations.
This template provides the substantive content and calculation methodology to help you
prepare — but you must transfer your figures to the official worksheet before filing.
The official form is available at https://www.tn.gov/humanservices/for-families/child-support-services/child-support-guidelines/child-support-calculator-and-worksheet-1.html.
Do not file this document directly with the court.

• Low-Income Provision: When obligor's income falls in the shaded area of the schedule, a second calculation using only the obligor's income is performed; the lesser amount applies.
• Modification: Requires a significant variance of 15% or more (7.5% for orders initially set under Income Shares).
• Income Imputation: If a parent fails to provide income evidence, median income figures may be imputed.
• Parenting Plan Required: All custody orders require a parenting plan specifying days with each parent.
