Arkansas Child Support Calculator
Free Arkansas child support calculator using the income-shares model. Estimate monthly payments based on both parents' income and custody schedule.
How This Calculator Works
Calculation methodology and assumptions
Arkansas uses the income-shares model for calculating child support. Both parents' incomes are combined, then each parent's share of the total obligation is based on their percentage of combined income. The custodial parent's share is presumed spent directly on the child. This calculator provides an estimate — actual court orders may vary based on additional factors like extraordinary medical costs, educational expenses, and judicial discretion.
Key State Information

Example Calculation
How is child support calculated in Arkansas Child Support?
For two parents with gross monthly incomes of $5,000 and $3,000 and two children: In an income shares model, the combined income of $8,000 is looked up in the state's schedule to determine total child support obligation (e.g., $1,400/month). Each parent's share is proportional to their income — the higher earner pays 62.5% ($875) and the lower earner pays 37.5% ($525). The non-custodial parent typically pays their share to the custodial parent.
Result: Child support obligations vary dramatically by state. For this same scenario, obligations might range from $600/month in some states to $1,200+/month in others. Always use state-specific guidelines for accurate estimates.
What Affects Your Results
State Model
Arkansas Child Support use either income shares (39 states), percentage of income (6 states), or the Melson formula (3 states). The model dramatically affects results at different income levels.
Combined Parental Income
Higher combined income means higher total obligation, but the percentage of income devoted to support decreases at higher levels. Most guidelines have income caps.
Number of Children
Support increases with more children but not linearly. Two children might cost 1.5x one child rather than 2x, reflecting economies of scale.
Custody Arrangement
Shared or joint custody (significant time with both parents) reduces the transfer payment since both parents directly fund the child's expenses during their parenting time.
