Simple Child Support Calculator

For a simple and easy calculation of child support in Connecticut, we suggest trying the AllLaw's calculator. Connecticut appears to lack an official, government-sponsored calculator that is reliable and easy to use.

The AllLaw's calculator is quite simple and easy to use. But note that the estimator may not always be accurate and completely up to date for 2024.

In the state of Connecticut, the result of an online calculation should normally be interpreted carefully. You should treat the estimate as no more than a preliminary indication of the child support amount you could receive or be required to pay.

Connecticut Parenting Time Calculator

While Connecticut child support guidelines focus on which parent is the "custodial parent", parenting time shares have the potential to affect child support. Actual parenting time percentages could influence the order a judge makes or how much parents agree to.

Use this overnights calculator to work out your parenting time percentage. Most states measure parenting time based on overnight stays.

How Child Support is Calculated in Connecticut


Child support payments in Connecticut are calculated using the income shares only method. Payments depend on the combined income of the parents as well as the number of children eligible for support. A bigger combined income or extra children typically means higher payments.

The amounts transferred also depend on each parent’s income share or income percentage. Connecticuters paying the most support are non-custodial parents with high incomes. The biggest receivers are low-income parents with primary physical custody and a high-earning payer.

We refer to the method as "income shares only" since Connecticut lacks a well-defined way of adjusting payments for the exact amount of parenting time each parent contributes. A parent’s share of care time is not a detailed part of the guidelines, as is usually the case with income sharing models.

Courts consider many factors as listed in Connecticut General Statutes Section 46b-8. As well, the Connecticut Child Support Guidelines contain a mathematical formula to provide some predictability and consistency when calculating payments.

There is a presumption that child support calculated under the Connecticut Child Support Guidelines is the correct amount. A deviation occurs when the parents agree between themselves to a lesser or higher amount of child support than is dictated by the formula, or when a Judge decides that the calculation under the Guidelines would be inequitable or inappropriate in a particular case.
