Tennessee uses the income shares model for child support: a basic obligation is read from the state schedule using both parents' combined income and the number of children, then divided by each parent's share of that income. This page calculates the shares; the schedule amount comes from the official Tennessee source.
How Tennessee Child Support Is Calculated
The National Conference of State Legislatures lists Tennessee among the income shares states. The calculation has four steps: add both parents' incomes; find the basic obligation for that combined income and number of children in the Tennessee schedule; divide it between the parents in proportion to their incomes; then apply the worksheet's adjustments.
Tennessee starts from each parent's gross income, before taxes, with the adjustments its worksheet allows.

Worked Example: Tennessee Income Shares
With the default figures, the paying parent has $5,000 a month and the other parent $3,000. Combined income is $8,000, so the paying parent's share is 62.5% and the other parent's is 37.5%. With a $150 health insurance premium and $200 of work-related childcare, an income-share split puts $93.75 and $125.00 on the paying parent. To finish the calculation you would look up $8,000 of combined income and 2 children in the Tennessee schedule and apply those shares.
Insurance, Childcare and Parenting Time in Tennessee
Most income shares worksheets divide the children's health insurance premium and work-related childcare by income share. This page shows that split as an illustration only: Tennessee's own rule for these costs was not confirmed for this page, so check the official worksheet before relying on it.
Any adjustment for parenting time (overnights) is made on the state worksheet or by the court and is not estimated here.
Estimate Only: Who Sets the Tennessee Order
This page gives an estimate only — the court or the state child support agency sets the order, and either can depart from the guideline where the law allows. Before relying on any figure, run the same figures through the Tennessee child support guidelines and calculator.
If your income, the parenting schedule or the children's needs change, ask the court or the agency to review the order, and keep paying the ordered amount until it is changed. Last updated: October 2026.
