Child Custody Calculator
Determining child custody arrangements can be emotionally challenging and legally complex. Parents often struggle to understand how custody time is divided, how percentages are calculated, and whether an arrangement qualifies as joint or primary custody. That’s where a Child Custody Calculator becomes an extremely helpful tool.
Our Child Custody Calculator is designed to give parents a clear, quick, and easy estimate of parenting time based on the number of days and overnights each parent spends with the child. Whether you are preparing for mediation, discussing custody schedules, or simply trying to understand your current arrangement, this tool helps bring clarity to an otherwise confusing process.
What Is a Child Custody Calculator?
A Child Custody Calculator is an online tool that estimates:
- Each parent’s time share percentage

Example Custody Calculation
Let’s look at a simple example:
- Parent 1: 180 days, 180 overnights
- Parent 2: 185 days, 185 overnights
- Schedule: Alternating Weeks
Result:
- Parent 1 Time Share: ~49.3%

- Custody Type: Joint / Shared Custody (50/50)
This example shows how close schedules often result in joint custody, even if the numbers aren’t perfectly equal.
Understanding Custody Types in Results
The calculator categorizes custody into common types:
Joint / Shared Custody (50/50)
Both parents spend nearly equal time with the child.
Joint Custody (40/60)
One parent has slightly more time, but both remain actively involved.
Primary Custody
One parent has a significantly higher percentage of parenting time.
These labels are general estimates and may vary depending on local family laws.
