Connecticut child support calculator

Connecticut follows the income-shares model. The idea is that a child should receive the same proportion of parental income they would have if the parents lived together. Both parents’ net weekly income is combined, the basic support obligation is read from the schedule, and each parent is responsible for the share that matches their percentage of the combined income. The parent the children do not primarily live with pays their share to the other.

The heart of the calculation is the Schedule of Basic Child Support Obligations — a table indexed by combined net weekly income (from $50 up to $4,000 per week) and the number of children (one to six). This calculator uses the current schedule, which took effect July 1, 2015. Combined income is rounded to the nearest $10 row.

To the basic obligation Connecticut adds qualifying child care and the children’s health-insurance premium, which are shared in proportion to income and computed on the worksheet. The combined figure is the total obligation, split by income share. A self-support reserve protects low-income paying parents, and above $4,000 net weekly the presumptive amount becomes a range set with court discretion.

Connecticut does not use a separate shared-custody worksheet, but shared physical custody is one of the enumerated deviation criteria a court may apply to adjust the presumptive amount (§46b-215a-5c). This calculator computes the standard presumptive obligation; a court may deviate for shared parenting and the other statutory criteria.

It combines both parents’ income, reads the guideline schedule, adds child care and health insurance, and splits the total by income share. It does not compute net income from your pay stubs, run the full health-care/child-care contribution worksheet, apply the self-support reserve in detail, or apply a deviation the court may order. For a figure you can file, use the official Connecticut worksheet or consult an attorney.
