Kentucky child support calculator

Kentucky follows the income-shares model. A child should receive the same share of parental income they would have if the parents lived together. Both parents’ adjusted monthly gross income is combined, the basic support obligation is read from the table, and each parent is responsible for the share that matches their percentage of the combined income. The non-custodial parent pays their share to the other.

The core of the calculation is the table in KRS 403.212 — indexed by combined monthly adjusted parental gross income (from $0 up to $30,000) and the number of children (one to six). The current table took effect July 1, 2025. “Adjusted” gross income means gross income less any maintenance or prior-born child support actually paid. Above $30,000 a month the court uses its discretion, and every order carries a $60 minimum.

To the basic obligation Kentucky adds reasonable work-related child care and the children’s health-insurance premium; the combined figure is the total obligation, divided in proportion to income (KRS 403.211). Extraordinary medical or other expenses may also be shared. Each parent is responsible for their percentage of the total.

Unlike some states, Kentucky’s guideline table does not contain an automatic parenting-time formula. A court may deviate from the guideline amount when applying it would be unjust or inappropriate — for example for extended or shared parenting time, a child’s extraordinary needs, or the parents’ combined income above the table — but the deviation is discretionary and must be supported by written findings.

It combines both parents’ income, reads the KRS 403.212 table, adds child care and health insurance, and splits the total by income share. It does not compute adjusted gross income from your pay stubs, apply a shared-parenting or extraordinary-needs deviation, or set support above the $30,000 table.
