Each party’s verified income and statutory deductions
Parenting schedule and childcare expenses
Add-ons, deviations, and Court-specific practices
Caps, adjustments, and statutory discretion applied by a Judge or agreed upon in settlement
Tax considerations, insurance costs, and other case-specific factors
