Connecticut counts child support by the week, on net income, and since August 1, 2026 it uses a new schedule. A noncustodial parent with $1,000 of net weekly income, facing $500, owes $312 a week for two children: the combined $1,500 reads $465 in the schedule, and the parent's share is rounded to a whole percent before it is applied. The Commission for Child Support Guidelines extended the schedule from $4,000 to $6,000 of weekly income, raised the income that triggers any obligation to $150, and widened the darker shaded low-income area, built on a self-support reserve of $362 a week. Above $6,000 there is a range rather than a number. Shared physical custody is not a formula in Connecticut: the higher earner's presumptive amount stands, and the judge may deviate.
Guideline child support in Connecticut, per month
$945
$11,336 a year · $218 a week, the period of the CT table
| Combined net income, a month | $8,000 |
| Weekly income used (rounded to $10) | $1850 combined, $1150 paying parent |
| Schedule block, 1 child (a month) | $1,499 |
| Paying parent’s share, rounded to a whole percent | 63.0% |
| Shared physical custody | no formula in Connecticut: possible deviation only |
Estimate under the Connecticut guideline as published, from the incomes you enter. Deviations, imputed income, other children and the judge's findings can change the order. How this is calculated.
Weekly figures, rounded twice
Everything on the Connecticut worksheet is weekly. Net income is gross pay minus federal, state and local income taxes, Social Security or a mandatory retirement plan, Medicare, the Connecticut paid leave contribution, health premiums for the parent and dependents, mandatory union dues and uniforms, and support already ordered for other children. Hours beyond 45 a week do not count. The combined figure is rounded to the nearest $10, the share of each parent to a whole percent, and the order to the nearest dollar. The calculator above takes monthly incomes and converts them at 52 weeks to the year, then shows the result per month; multiply by 12 and divide by 52 for the weekly figure the court writes.
The shaded area and its cliff
A noncustodial parent whose own net weekly income falls in the darker shaded cells is a low-income obligor. For that parent the schedule is read on their own income alone, and the amount in the block is the whole order. The shading stops at $470 for 1, $550 for 2, $610 for 3, $680 for 4, $750 for 5 and $830 for 6 children. Every shaded line below $362 is 10% of income for one child, the floor the new commission chose.
| Paying parent, net weekly | Other parent | Weekly order, one child |
|---|---|---|
| $470 | $2,000 | $105 |
| $480 | $2,000 | $81 |
The table shows a quirk of the method. At $470 the parent pays the shaded amount in full; $10 more and the parent leaves the shaded area, the other parent's income enters the calculation, and the share of the combined amount can come out lower. Courts see these cases, and a deviation is the usual remedy.
Above $6,000 a week
Section 46b-215a-2c(a)(2) no longer leaves high incomes to pure discretion. The amount printed at $6,000 is the minimum presumptive order and the percentage printed on the same line, times the actual combined income, is the maximum. With $5,000 and $2,000 a week and two children, the paying parent's 71% share gives a range of about $778 to $908 a week; the calculator shows the floor.

Monthly support for one paying parent, the other parent without income
| Paying parent’s monthly income | 1 child | 2 children | 3 children | 4 children |
|---|---|---|---|---|
| $2,000 | $425 | $507 | $542 | $550 |
| $3,000 | $693 | $1,053 | $1,270 | $1,417 |

| $8,000 | $1,499 | $2,227 | $2,630 | $2,938 |
| $10,000 | $1,755 | $2,591 | $3,038 | $3,393 |
| $12,500 | $2,045 | $3,007 | $3,501 | $3,913 |
| $15,000 | $2,375 | $3,475 | $4,030 | $4,502 |
| $20,000 | $2,912 | $4,264 | $4,944 | $5,525 |
How the amount is set. Round the combined net weekly income (or, for a low-income obligor, the noncustodial parent's income) to the nearest ten dollars and read the block for the number of children (§ 46b-215a-2c(c)(3)(A)-(B)). Each parent's share = own net income / combined, rounded to the nearest whole percentage, x the obligation (§ 46b-215a-2c(c)(4)). source
Income. Gross income (wages, overtime and second jobs up to 45 paid hours per week, self-employment, benefits, etc.; § 46b-215a-1(11)) minus allowable deductions: federal, state and local income tax, Social Security or mandatory retirement, Medicare tax, CT FMLI contributions, health insurance premiums for the parent and dependents, court-ordered life and disability insurance, mandatory union dues, mandatory uniforms and tools, alimony and child support ordered for others, and the qualified child deduction (§ 46b-215a-2c(c)(2), § 46b-215a-2c(d)).
Above the table. Above $6,000 combined net weekly income, awards are set case by case: the amount at $6,000 is the minimum presumptive obligation and the maximum is combined net weekly income x the percentage shown at $6,000 (12.61%, 18.27%, 20.97%, 23.42%, 25.77%, 28.01% for 1-6 children) (§ 46b-215a-2c(a)(2)).
Parenting time. No time-based formula. In shared physical custody (substantially equal time; exact equality not required, § 46b-215a-1(24)) the presumptive order is the presumptive current support amount of the parent with the higher net weekly income, payable to the lower-income parent (§ 46b-215a-2c(c)(7)(B)); a deviation may apply if the arrangement substantially reduces/increases expenses or incomes are substantially equal (§ 46b-215a-5c(b)(6)(A)). Split custody: offset of the two theoretical amounts (§ 46b-215a-2c(c)(7)(A)).
Child care and health care. Qualifying child care costs (employment-related, licensed source) are shared by the noncustodial parent's percentage share of combined net disposable income; low-income obligors pay a reduced share (e.g. 20% of costs when the custodial parent's income is outside the shaded area) (§ 46b-215a-2c(g)). Each award must include health care coverage: insurance at reasonable cost, application for HUSKY B, and/or cash medical support; no HUSKY contribution may be ordered from a low-income obligor (§ 46b-215a-2c(f)). Health care coverage and child care contribution are separate award components added to current support (§ 46b-215a-2c(a)(1), (f), (g)).
Low incomes. The schedule's darker shaded low-income area is based on a self-support reserve of $362 net per week (125% of the 2024 federal poverty guideline for one person, preamble (e)); in that area the obligation uses only the noncustodial parent's income and is 10% of net income for one child below $362, phased out up to $470 (§ 46b-215a-1(16), § 46b-215a-2c(c)(3)(A)). Arrearage payments for a low-income obligor are the greater of 10% of current support or $1 per week (§ 46b-215a-3a).
When support ends. Support runs to 18; an unmarried child who is a full-time high school student is maintained until completing grade 12 or turning 19, whichever is first (Conn. Gen. Stat. § 46b-84(b)); support for a child with a disability may run to 21 (§ 46b-84(c)). Educational support orders for college are possible under § 46b-56c. source
Worth knowing in Connecticut
- Connecticut's new guidelines took effect August 1, 2026, replacing the 2015 guidelines; the schedule now runs to $6,000 combined net weekly income (previously $4,000). source
- Connecticut works in weekly amounts: incomes and orders are entered on the worksheet as weekly figures (§ 46b-215a-2c(b)). source
- The low-income area is built on a self-support reserve of $362 net per week (125% of the 2024 federal poverty guideline), and the minimum income triggering an obligation rose from $50 to $150 per week (preamble). source
- Income from hours worked beyond 45 paid hours per week is excluded from gross income (up to 52 hours it may justify a deviation) (§ 46b-215a-1(11), § 46b-215a-5c(b)(1)(E)). source
- Connecticut rejects a time-sharing formula: shared physical custody is a deviation criterion, not a mathematical adjustment (preamble (j)(3)(D), § 46b-215a-5c(b)(6)(A)). source
