Want to quickly calculate your child custody percentage? Here is a free online calculator to do it.

You’ll get an accurate calculation of your parenting time %, as well as the number of overnights this corresponds with per year. Use the results for child support assessments and other purposes.

The calculator uses your regular custody schedule, which can be on a weekly, fortnightly, tri-weekly or monthly basis. You also have the option to include overnights outside your ordinary schedule, such as vacation time and special days.

Disclaimer

We believe this calculator is mathematically accurate and produces a calculation that should withstand scrutiny in most courts of law. However, custody arrangements vary by state, and some may have unique methods for determining percentages, including manual overnight counting.

We have been transparent about how the calculator works, but it is the user’s responsibility to apply it correctly to their situation. While this tool can be helpful, if in doubt, you should verify that the results align with the requirements in your jurisdiction.
