Kentucky Child Support Calculator
Estimate your child support obligations in Kentucky using the income shares model. Understand how support is calculated, what factors matter, and what to expect. Updated for 2026.
Kentucky uses the Income Shares Model under KRS § 403.212. Both parents' gross incomes are combined and a basic child support obligation is determined from the statutory schedule table based on combined monthly income and number of children. The obligation is divided between parents in proportion to their respective incomes. Adjustments are made for health insurance premiums, work-related childcare costs, and extraordinary medical expenses. The guideline amount is presumptive; deviations require written findings that application would be unjust or inappropriate per KRS § 403.211.
