CONNECTICUT SUPPORT GUIDELINE
Connecticut child support calculator & worksheet
The Connecticut child support calculator estimates basic weekly support from both parents’ net weekly income. Check allowable deductions and the state’s income definition before entering figures. This CT worksheet provides the base guideline estimate; custody adjustments, child care, health care and arrearages need the full guidelines.

How Connecticut child support law works
Legal starting point. Connecticut’s child-support regulations use a weekly net-income worksheet and a Schedule of Basic Child Support Obligations. The schedule produces a presumptive amount, but the regulations include separate rules for low-income, multi-family, custody, and deviation situations. Read Connecticut Child Support and Arrearage Guidelines.
How the guideline is calculated
Each parent’s allowable-deduction net income is combined, rounded for the schedule lookup, and used to find the weekly basic obligation. The result is allocated by each parent’s share of combined weekly net income before case-specific credits or additions are considered.
What this site’s worksheet covers
Uses Connecticut RCSA § 46b-215a-2c, effective August 1, 2026, and the Schedule of Basic Child Support Obligations posted to the Connecticut eRegulations System on March 11, 2026. Connecticut uses weekly net income after allowable deductions; line 15 combined net weekly income is rounded to the nearest ten dollars for the schedule lookup. The schedule amount is weekly basic support. Each share is rounded to the nearest whole percent under §46b-215a-2c(c)(4), and final weekly support is rounded to whole dollars under (c)(6). This module applies the darker-shaded payer-only schedule and uses rounded combined income for both the ordinary lookup and whole-percent allocation. Social Security dependency benefits, health care, child care, arrearage payments, multi-parent worksheets, shared physical custody and deviations require the full Connecticut worksheet. For combined net weekly income above $6,000, the $6,000 schedule amount is the minimum presumptive support amount and the final order is case-specific.
Documents that make the worksheet more useful
CCSG-1 worksheet; weekly net income, health care, child care, and arrearages. Gather the records that support the income, parenting-time, insurance, child-care, and other adjustment entries that apply to the family. The encoded rule version already identifies the August 1, 2026 schedule. Low-income schedule shading, dependency benefits, and full custody/expense adjustments still need reconciliation.
For a filing or agreement, complete the official court forms linked on this page. They use the same guideline structure explained here, and the court applies it to the facts of the case.
Before you enter your numbers
Why is Connecticut asking for weekly net income?
Connecticut uses a weekly net-income schedule. A monthly salary must be converted to the worksheet period after applying the allowed deductions; dividing a monthly amount by four would assume only 48 weeks in a year. The guideline also allocates health-care and child-care obligations separately from basic support.
Prepare this: Label every source figure as weekly, biweekly, monthly, or annual. Keep the deduction calculation and the health-care and child-care portions of the official worksheet together.
Read the relevant official instructions: Connecticut Child Support and Arrearage Guidelines.
These preparation notes explain one part of the state guideline. A new estimate does not change an existing order; a modification request does.
How Connecticut cases actually get to a number
Convert income to weekly net using the regulation’s allowable deductions before touching the schedule. Rounding rules on the schedule matter. Multi-family and low-income cases leave the ordinary combined-income path.
Connecticut uses a weekly net-income worksheet and a Schedule of Basic Child Support Obligations. The schedule amount is allocated by each parent’s share of combined weekly net income. That is a different path from neighboring states that use another model, so do not import a table, percentage, or overnight credit from somewhere else.
Parenting time in Connecticut
Shared physical custody is a different worksheet analysis in Connecticut. A parenting plan with substantial time in both homes should not be run as a sole-custody schedule plus an invented credit.
Costs Connecticut usually treats separately
- Qualified child-care costs
- Health-care coverage contributions
- Unreimbursed medical expenses
- Extraordinary education costs when ordered
When Connecticut courts leave the guideline
The regulations list deviation criteria, including a child’s best interests and a parent’s other support orders. The schedule remains the presumptive starting point.
Official Connecticut forms to keep beside this guide

Low-income schedule shading, dependency benefits, and full custody/expense adjustments still need reconciliation. The primary authority is the published Connecticut source. Fill the official form from source documents. Use this page only to check that you chose the right Connecticut path—primary versus shared, table versus percentage, add-ons versus basic support.

Superior Court family sessions hear most cases; Support Enforcement Services handles IV-D. Use the current Child Support and Arrearage Guidelines, not a prior schedule year.
Questions about Connecticut child support
What does a Connecticut weekly support example look like?
For one child, net weekly incomes of $900 and $900 combine to $1,800. The schedule effective August 1, 2026 lists $340 in basic weekly support. Each parent’s 50% share is $170 before health care, child care, dependency benefits, custody adjustments, arrearages or deviations. These are base allocations, not two payments or a final court order. The ordinary combined-income branch applies in this example.

How much is child support in CT?
There is no single amount for every family. The ordinary calculation uses both parents’ net weekly income, child count and income shares; the darker-shaded low-income branch uses the paying parent’s income alone. Allowable deductions and case-specific adjustments matter. Enter the supported scenario in the worksheet to review a base estimate, then compare it with the complete Connecticut guidelines.

Should the CT child support calculator use weekly or monthly pay?
Connecticut’s formula uses weekly net income after allowable deductions. In this site’s income worksheet, enter each source amount once with its actual pay frequency; the weekly formula fields are calculated from those records and permitted deductions. Check the resulting weekly figures against the official worksheet.
Prepare income for the correct pay period
Does the Connecticut chart include shared custody and arrearages?
The basic support schedule is only part of the full Connecticut calculation. This module’s notes identify separate treatment for shared physical custody, health care, child care, dependency benefits, arrearage payments and deviations. Use the official worksheet for those components rather than adding a homemade custody discount to the chart amount.
