Understanding Custody Time Calculations

Calculating custody time is an important aspect of co-parenting arrangements. This calculator helps parents track and calculate the percentage of time each parent spends with their children, which can impact custody designations and child support calculations.

Primary vs. Secondary Custody

In many jurisdictions, primary custody is typically assigned to the parent who has the child for more than 50% of the time. Secondary custody (sometimes called non-custodial parenting time) refers to the time the child spends with the other parent. These designations can affect legal rights and financial obligations.

How Custody Time Affects Child Support

The amount of time each parent spends with the child often factors into child support calculations. Many states use a formula that considers the custody percentage when determining support obligations. Generally, as a parent's custody time increases, their child support obligation may decrease.

How to Use This Calculator

Enter your custody schedule by selecting days or blocks of time for each parent. The calculator will determine the percentage of time each parent has with the child, including overnight stays, and provide a visual representation of the custody arrangement.
