Arkansas Child Support Calculator

Arkansas child support is governed by Administrative Order No. 10, issued by the Arkansas Supreme Court. This order adopts the Income Shares model, which rests on the principle that children should receive the same proportion of parental income they would have received had their parents remained together. The order is periodically updated to reflect economic research and changes in living costs, and it serves as binding authority for all Arkansas courts when establishing or modifying child support. Judges have limited discretion to deviate from the guideline amounts, but any deviation requires written findings of fact that specifically explain why the standard amount is unjust or inappropriate under the circumstances.

Under Administrative Order No. 10, the first step is determining each parent's monthly adjusted gross income. Both parents are required to fully disclose their earnings through sworn financial affidavits submitted to the court. The court then combines both adjusted gross incomes to produce a single combined monthly figure, which is cross-referenced against the guidelines table that is attached to the order. That table lists basic monthly obligations for one through six or more children at various combined income levels, making it straightforward to identify the total obligation once the income figures are established.

The guidelines table in Administrative Order No. 10 is grounded in economic research on household spending patterns for children at various income levels. Once the basic obligation is identified from the table, it is apportioned between the parents in proportion to each parent's adjusted gross income share of the combined total. The non-custodial parent then pays their apportioned share as a direct transfer payment to the custodial parent each month. Any shared costs for childcare and health insurance are handled as additions to the basic obligation before apportionment, ensuring both parents contribute proportionally to all child-related expenses.

Arkansas defines gross income broadly to capture all income from any source, whether from employment or otherwise. Wages, salaries, commissions, bonuses, overtime pay, tips, and self-employment income are all included. So too are dividends, rental income, interest, pension and retirement benefits, Social Security benefits excluding SSI, disability benefits, and unemployment compensation. This comprehensive definition ensures that parents cannot shield earnings in alternative income streams to artificially reduce their child support obligation, and courts are authorized to impute income when a parent is voluntarily unemployed or underemployed relative to their earning capacity.

Self-employed parents face particular scrutiny when reporting income under Arkansas guidelines. Courts look at gross business receipts minus ordinary and necessary business expenses to determine net self-employment income. However, expenses that primarily benefit the parent personally or that reduce taxable income without reducing actual cash flow may be disallowed. Arkansas courts have consistently held that the goal is to capture the parent's true economic capacity rather than the number appearing on a tax return after aggressive deductions. Depreciation and non-cash deductions receive especially close scrutiny because they reduce paper income without reducing actual funds available.

Adjusted gross income in Arkansas is calculated by subtracting allowable deductions from gross income. The primary deduction is for pre-existing child support obligations that the parent is actually paying under a court order for children from a different relationship. Courts may recognize additional deductions in limited circumstances. The adjusted gross income is the figure that enters the income shares formula, preventing parents with prior support obligations from being required to over-extend themselves financially while also protecting children from reduced support due to a parent's subsequent family obligations.

Beyond the basic child support obligation, Arkansas guidelines require both parents to contribute to the cost of work-related childcare and health insurance premiums for the child. Work-related childcare costs include daycare, after-school programs, and other supervised care arrangements that allow the custodial parent to maintain employment or pursue education. These costs are added to the basic obligation before apportionment so that both parents share the financial burden of keeping the child in appropriate care during working hours. Costs that are not work-related, such as childcare during the parent's leisure time, are generally not eligible for inclusion.

Health insurance for the child is addressed separately in Arkansas child support proceedings. Courts typically order the parent who has access to the most reasonably affordable coverage through an employer or group plan to maintain health insurance for the child. The cost of the child's share of the health insurance premium is factored into the overall child support calculation. If the non-custodial parent carries the insurance, they may receive credit against their basic support obligation equal to the premium paid; if the custodial parent carries it, the non-custodial parent may owe an additional share of that cost on top of the basic obligation.

Extraordinary medical expenses not covered by insurance are handled separately from the regular child support order. Arkansas courts typically address uninsured and unreimbursed medical costs through a percentage-sharing arrangement matching each parent's income share. Major expenses such as orthodontics, surgeries, or ongoing therapy for chronic conditions may be addressed in the original order or handled through motion practice as they arise. Parents are encouraged to communicate promptly when significant medical expenses occur to avoid disputes about responsibility. Receipts and explanation-of-benefits documents from the insurer are typically required to substantiate claims for reimbursement.

Arkansas recognizes multiple custody arrangements, and the type of custody directly affects how child support is calculated and transferred. In a primary custody arrangement where the child lives mainly with one parent, the non-custodial parent pays their income-proportional share of the guideline obligation as a direct monthly transfer payment. The basic calculation under Administrative Order No. 10 is straightforward in these situations, and the guideline amount serves as a strong presumption that courts apply unless one parent establishes a specific reason for deviation through documented evidence.

When parents share physical custody more equally, Arkansas courts have discretion to adjust the standard guideline amount to reflect the reality that both parents are incurring direct out-of-pocket expenses for the child during their respective custody periods. Arkansas does not prescribe a rigid shared-custody adjustment formula the way some states do, but courts routinely apply a cross-credit approach in which each parent's guideline obligation is calculated as if they were the non-custodial parent, and the higher-income parent pays only the net difference. This prevents one parent from being required to pay a full guideline amount while also bearing substantial direct custody expenses.

Split custody arrangements arise when there are multiple children and each parent has primary custody of at least one child. In these cases, Arkansas courts calculate a separate child support obligation for each parent as if they were the non-custodial parent for the child living with the other parent. The two obligations are then offset against each other, with the parent who owes more making a net payment to the other. This approach fairly accounts for the direct financial responsibility each parent bears for the children living in their home and avoids the inequity of requiring large cross-payments when both parents are already supporting children.

Arkansas courts may deviate from the guideline amount when strict application of the formula would be unjust or inappropriate given the specific facts of the case. Common grounds for deviation include a child's extraordinary medical needs, significant educational expenses not accounted for in the standard guideline, a parent's extraordinarily high or low income that makes the standard formula produce an unreasonable result, or other unusual circumstances unique to the family. Written findings must accompany any deviation so that reviewing courts can evaluate whether the departure from the guidelines was legally justified and served the child's best interests.

Parents who believe the standard guideline amount does not accurately reflect their situation should be prepared to present detailed financial documentation and specific legal arguments at the hearing. Voluntary agreements between parents to pay below the guideline amount are not automatically approved by the court; the judge must independently find that any agreed deviation serves the child's best interests. This requirement protects children from parents who might otherwise agree to below-guideline support simply to avoid litigation, leaving the child inadequately supported over an extended period.

Child support orders in Arkansas may be modified when there has been a material change in circumstances since the last order was entered. A change of at least 20% or $100 per month in the calculated obligation, whichever is less, is considered a material change sufficient to support a modification request. Changes in custody arrangements, significant shifts in either parent's income, the elimination of a major childcare expense, or changes in the child's needs can all qualify. Either parent may file a petition to modify, and the court will recalculate the obligation using current incomes and the version of the guidelines in effect at the time of the modification proceeding.
