Oregon Child Support Calculator

How to Use the Oregon Child Support Calculator as an Effective Tool


The state of Oregon uses specific guidelines to determine child support. Parents who want to estimate either how much child support they owe, or how much child support they will receive, should use Oregon’s interactive child support calculator, which is provided by the state.

Tips for Using the Oregon Child Support Calculator

  • Only use the Oregon child support calculator provided on the state’s Department of Justice web site.

  • Third-party child support calculators may not provide users with a reliable, accurate child support estimate.

  • Be aware that the Oregon child support calculator is designed to provide an estimate only.

  • In order to use the calculator, you will need to know the total income of both parents, including spousal support, Social Security or veteran's benefits, and all other sources of income.

  • You will also need to know about certain expenses for each parent, including taxes, union dues, health premiums, and any other child or spousal support payments.

  • There is also a section for inputting the percentage of each parent's parenting time. Oregon provides a separate parenting time calculator that can be used to assist you in determining how parenting time is divided.
