TCBChild Support Calculator

About this calculator

Source of truth

The engine implements Arkansas Supreme Court Administrative Order No. 10 (the income-shares child support guidelines, effective July 1, 2020, as amended April 14, 2022) and Ark. Code Ann. § 9-12-312. The Family Support Chart of Basic Child Support Obligations is loaded from the official Administrative Office of the Courts publication.

  • Schedule effective date: 2020-07-01
  • Chart rows: 580 ($50 brackets, 1–6 children), digitized in full
  • Combined-income lookup rounds down to the $50 row (AO 10 § III(D))
  • Every fixture's basic obligation was confirmed against the official chart; treatise worked examples reproduce

How the order is built

Both parents' adjusted gross incomes are combined; the basic obligation is read from the chart and prorated by each parent's income share. Mandatory add-ons (health-insurance premium, work-related childcare, and extraordinary uninsured medical above the $250/child/year built into the chart) are prorated. Approximately-equal custody runs a dual-worksheet offset — Arkansas uses a straight offset with no 1.5× multiplier. Above the $30,000 combined-income cap, the top chart amount is a floor and any addition is discretionary (Parnell v. Ark. Dep't of Fin. & Admin., 2022 Ark. 52). A self-support reserve protects low-income payors: when the payor's gross is under $900/month the obligation is computed from the payor's gross alone with a $125 minimum (AO 10 § II(3)).

What this does NOT do

  • Generate a fillable AcroForm worksheet — Arkansas publishes the Child Support Worksheet in the AO 10 Forms Addendum, but not (as confirmed) as a fillable PDF; use this as the computation and transcribe
  • Split custody across separate custody groups (9:315.10-style)
  • The discretionary increment above the $30,000 chart cap
  • Alimony analysis (separate from the support calculation)
