Idaho's method
Income Shares model
Both parents' incomes are combined to estimate what they would have spent on the child if the family were intact, then each parent pays a share in proportion to their income. Used by most states.
This page explains the method — it doesn't calculate your amount. For an estimate, use Idaho's official child-support guidelines worksheet or calculator (search "Idaho child support calculator" on your state's judicial or child-support-services website). Because parenting time, add-ons, and judicial discretion all change the result, treat any online figure as a starting point and confirm it with a Idaho family-law attorney.
Need a number you can rely on?
A Idaho family-law attorney can run the worksheet for your situation.
