With child care and health insurance
Connecticut's guideline amount doesn't add child care costs.
| Costs | Guideline amount |
|---|---|
| No add-ons | $1,673 a month A→B |
| Child care $500 a month | $1,673 a month A→B |
| Child care $1,000 a month | $1,673 a month A→B |
| Health insurance $150 a month | $1,690 a month A→B |
| Health insurance $300 a month | $1,703 a month A→B |
Health insurance premiums are deducted from the paying parent's income. Child care and unreimbursed medical costs aren't part of the weekly amount: each parent pays a percentage of them as they come up, based on their share of the parents' income after support.
Things to know about this example
- Net income was estimated with Connecticut's standard assumptions (head of household for the parent the children live with, 2026 tax year). Your actual taxes may differ.
How Connecticut works it out
Connecticut uses the income shares model on net weekly income. The schedule gives one amount for the parents' combined net weekly income and the number of children; each parent owes their share, and the parent the children don't live with pays theirs as current support.
Net income is gross income minus income taxes based on all allowable exemptions, deductions and credits, Social Security and Medicare, CT Paid Leave contributions, health insurance premiums, and a few other listed items. Hourly wages count up to 45 paid hours a week. Connecticut prescribes no tax method, so the net income here is an estimate: the parent the children live with is assumed to file as head of household and claim them.
Connecticut has no parenting-time formula. When parents share physical custody with substantially equal time, the parent with the higher net weekly income pays their own presumptive amount to the other parent; a court may deviate.
