How Child Support is Calculated in Tennessee


Child support payments in Tennessee are calculated using the income shares category method. Payments depend on the combined incomes of the parents as well as the number of children. A larger combined income or more children usually means greater payments.

The amount paid or received by an individual parent also depends on their income percentage. The higher your percentage of combined parent income, the more you pay or less you receive.

Payments are also affected by which parenting time category applies. Payments may be lower because of a "shared" (fairly equal) care arrangement.

Tennesseans paying the most child support have high incomes and limited parenting time. Conversely, the biggest receivers are parents who (a) work little (b) have their kids most of the time and (c) have a high earner as the other parent.

The Child Support and Credit Worksheets are in an Excel document. Automated calculations simplify the task of completing them. In the workbook is a series of tabs along the bottom of the page, one for each worksheet. Also contained are instructions for completing the worksheets and another tab containing the TN Schedule of Basic Child Support Obligations.

The “Income Shares Model” means that, under our child support law, both parents’ income is considered in determining child support. Current Rules, Charts, Worksheets and important links can be found on the Tennessee Child Support Resources page.
