Arkansas Child Support Calculator 2026

What is Arkansas Child Support Calculator?

The Arkansas Child Support Calculator is a specialized digital tool designed to estimate the amount of child support one parent may be required to pay to the other under Arkansas law, specifically following the guidelines set by the Arkansas Supreme Court’s Administrative Order Number 10. This calculator takes into account the gross incomes of both parents, the number of children, health insurance premiums, and other allowable deductions to produce a legally-influenced support figure. For parents navigating separation, divorce, or paternity actions, understanding this calculation is essential for financial planning and legal compliance.

This tool is primarily used by divorcing parents, custodial and non-custodial parents, family law attorneys, and even mediators who need a quick, reliable estimate of potential support obligations. It matters because Arkansas uses an "income shares model," meaning both parents’ incomes are pooled to determine what they would have spent on their children if they lived together, ensuring a fair distribution of financial responsibility. Without an accurate calculator, parents risk underestimating their obligations or overestimating what they might receive, leading to costly legal disputes.

This free online Arkansas Child Support Calculator simplifies the entire process by automating the complex arithmetic and applying the correct statutory adjustments, allowing you to focus on your family’s future rather than getting lost in spreadsheets.

How to Use This Arkansas Child Support Calculator

Using this calculator is straightforward, even if you are unfamiliar with Arkansas family law. The tool divides the process into clear, logical steps that mirror the official worksheet used by Arkansas courts. Follow these steps to get an accurate estimate in less than five minutes.

1. Enter Each Parent’s Gross Monthly Income: Start by inputting the gross monthly income for both Parent A (typically the non-custodial parent) and Parent B (typically the custodial parent). Gross income includes wages, salaries, bonuses, commissions, self-employment income, disability benefits, unemployment compensation, and any other recurring cash flow. Do not deduct taxes or payroll deductions at this stage—Arkansas law uses gross income as the starting point.
2. Include the Number of Children and Custodial Arrangement: Select the total number of children for whom support is being calculated (from 1 to 6 or more). Then, indicate the custody arrangement: sole custody (one parent has the child more than 278 overnights per year) or shared custody (each parent has the child at least 146 overnights per year). This choice dramatically affects the final calculation because shared custody scenarios apply a time-adjusted formula.
3. Input Health Insurance and Other Mandatory Deductions: Enter the monthly cost of health insurance premiums that are paid for the children only (not the parent’s own coverage). Also, include any court-ordered child support from a prior relationship, mandatory union dues, or retirement contributions that are required by law. These amounts are subtracted from the paying parent’s income before the support obligation is computed.
4. Add Other Child-Related Expenses (Optional): If applicable, enter the monthly cost of work-related child care (daycare, after-school care) and extraordinary medical expenses not covered by insurance (e.g., orthodontics, therapy). These are typically shared proportionally between parents based on their incomes.
5. Review the Calculated Support Amount: After clicking "Calculate," the tool will display the estimated monthly child support payment, the proportional income share for each parent, and a breakdown of how the number was derived. You can adjust any input and recalculate instantly to see how changes in income or expenses affect the obligation.

For best results, have recent pay stubs, tax returns, and health insurance statements handy before you begin. The calculator is designed for estimation purposes; always consult a qualified Arkansas family law attorney for official legal advice.

Formula and Calculation Method

Arkansas child support is calculated using the Income Shares Model, which is codified in the Arkansas Supreme Court's Administrative Order Number 10. This model assumes that children should receive the same proportion of parental income that they would have received if the parents lived together. The formula involves combining both parents’ adjusted monthly incomes, applying a statutory percentage based on the number of children, and then dividing the obligation proportionally. The core formula is straightforward but requires careful handling of deductions and credits.

Each variable in this formula is defined by Arkansas law and must be calculated precisely. The "Percentage from Schedule" is not a flat rate; it comes from a detailed table in Administrative Order 10 that increases incrementally with income. For example, for one child, the percentage ranges from approximately 14% to 20% of combined income, depending on the income bracket. For two children, it ranges from 21% to 28%, and for three children, from 27% to 34%.

Understanding the Variables

Gross Monthly Income: This is the starting point for both parents. It includes wages, salary, tips, bonuses, commissions, self-employment net income, worker’s compensation, unemployment benefits, Social Security benefits (including SSDI for the child), and military pay. Arkansas courts may also consider gifts, trust distributions, or rental income if they are regular and substantial. Income is not reduced by taxes, Social Security, or Medicare withholding.

Adjusted Monthly Income: This is gross income minus specific allowable deductions: (1) health insurance premiums for the children only, (2) court-ordered child support from a prior relationship, (3) mandatory retirement contributions (e.g., Arkansas Public Employees Retirement System), and (4) mandatory union dues. Voluntary retirement contributions, 401(k) loans, or credit card payments are not deductible.

Combined Adjusted Income: The sum of both parents' adjusted monthly incomes. This figure determines which row of the child support schedule is used. If the combined income exceeds the highest amount on the schedule (currently $30,000 per month), the court may apply a percentage-based formula or deviate based on the child’s needs.

Basic Child Support Obligation: Found by locating the combined adjusted income in the schedule and reading across to the column for the correct number of children. This is the total amount both parents together are expected to contribute.

Proportional Share: Each parent’s income as a percentage of the combined income. This percentage is then applied to the basic obligation to determine each parent’s individual contribution.

Step-by-Step Calculation

First, add both parents’ gross monthly incomes together, then subtract any allowable deductions (health insurance, prior child support, mandatory retirement) to get the combined adjusted income. Second, locate this combined adjusted income in the Arkansas Child Support Schedule table (found in Administrative Order 10) and identify the basic support obligation for the correct number of children. Third, calculate each parent’s percentage share by dividing their individual adjusted income by the combined adjusted income. Fourth, multiply the basic obligation by each parent’s percentage to get their individual share. Fifth, if the non-custodial parent pays for health insurance or child care directly, those amounts are credited against their share. The final result is the amount the non-custodial parent pays to the custodial parent each month.

Example Calculation

Let’s walk through a realistic scenario to illustrate how the Arkansas Child Support Calculator works in practice. This example involves a typical family with one child, standard health insurance costs, and no extraordinary expenses.

Step 1: Calculate Adjusted Incomes. John’s gross income is $5,000. He deducts the health insurance premium for the child ($400), so his adjusted income is $4,600. Sarah’s gross income is $3,000. She has no allowable deductions (daycare is handled later), so her adjusted income remains $3,000. Combined adjusted income = $4,600 + $3,000 = $7,600.

Step 2: Find Basic Support Obligation. Using the Arkansas Child Support Schedule for one child at a combined income of $7,600, the basic obligation is approximately $1,140 per month (exact figure depends on the specific schedule bracket; for this example, we use a representative value from the 2025 schedule).

Step 3: Calculate Proportional Shares. John’s share = ($4,600 / $7,600) = 60.5%. Sarah’s share = ($3,000 / $7,600) = 39.5%. John’s portion of the basic obligation = $1,140 × 0.605 = $690. Sarah’s portion = $1,140 × 0.395 = $450.

Step 4: Adjust for Child Care and Health Insurance. John already pays $400 for health insurance. The total cost of child care is $600. These costs are shared proportionally. John’s share of child care = $600 × 0.605 = $363. Sarah’s share of child care = $600 × 0.395 = $237. Since John pays $400 for insurance (which is more than his share of the combined insurance cost, but here insurance is a fixed amount), we credit him for the full $400. The net calculation: John owes his share of the basic obligation ($690) plus his share of child care ($363) minus the insurance credit ($400) = $653. However, Arkansas courts typically treat health insurance as a direct credit against the obligor’s share, so John’s net monthly payment to Sarah is $653.

In plain English, John would pay Sarah approximately $653 per month in child support. This amount covers his share of the child’s basic living expenses and daycare, after accounting for the health insurance he already pays directly.

Another Example

Consider a shared custody scenario. Maria and David have two children. Maria earns $4,000 per month, David earns $6,000 per month. They share custody equally (each has the children 183 overnights per year). There are no health insurance or daycare costs. Combined adjusted income = $10,000. For two children, the basic obligation from the schedule is approximately $2,100. Maria’s share = 40% ($4,000 / $10,000), David’s share = 60%. Their individual obligations are $840 and $1,260 respectively. However, in shared custody, the court applies a multiplier (typically 1.5 times the basic obligation for the parent with less income, but the actual formula is more complex). Using the Arkansas shared custody formula, the net support from David to Maria might be reduced to around $420 per month because both parents are providing substantial care. This example shows how custody time dramatically changes the outcome.

Benefits of Using Arkansas Child Support Calculator

Using a dedicated Arkansas Child Support Calculator offers significant advantages over manual calculations or generic online tools. This tool is specifically programmed to reflect the exact formulas, schedules, and deduction rules found in Arkansas Administrative Order 10, ensuring that your estimate is as close to a court-ordered figure as possible without legal representation. Below are the key benefits that make this calculator indispensable for parents and legal professionals alike.

• Instant and Accurate Estimations: Manual calculations using the official Arkansas schedule require looking up combined income in a multi-page table and performing several multiplications and divisions. A single math error can throw off the estimate by hundreds of dollars. This calculator automates the lookup and arithmetic, delivering a precise result in seconds. It reduces the risk of human error, especially when dealing with high incomes, multiple children, or complex deductions like prior child support orders.
• Transparency and Understanding of the Process: The tool provides a detailed breakdown of how each number is derived, including each parent’s income share, the basic obligation, and any credits. This transparency helps parents understand why a certain amount is calculated, which can reduce conflict during negotiations. When both parties see the same objective numbers, they are more likely to reach a settlement without expensive litigation.
• Time and Cost Savings: Hiring an attorney to run preliminary child support numbers can cost $200–$500 per hour. A free online calculator gives you the same baseline estimate in minutes, allowing you to enter mediation or court proceedings with a clear understanding of your financial position. This can significantly reduce the number of billable hours you need from your lawyer.
• Scenario Planning for Life Changes: Life is dynamic—jobs change, incomes fluctuate, and custody arrangements evolve. With this calculator, you can instantly adjust inputs to see how a raise, a new job with different benefits, or a change in custody time would affect support. This is invaluable for parents considering a modification of an existing order or planning for future financial shifts.
• Compliance with Arkansas Law: Unlike generic child support calculators that use national averages or outdated formulas, this tool is built specifically for Arkansas. It incorporates the exact income brackets, percentage rates, and deduction rules from the most recent version of Administrative Order 10. Using a state-specific calculator ensures that your estimate is legally relevant and can be presented to a court as a good-faith starting point.

Tips and Tricks for Best Results

To get the most accurate and useful estimate from the Arkansas Child Support Calculator, follow these expert tips. Understanding the nuances of the law and common pitfalls will help you avoid surprises and ensure your calculation reflects what a court would likely order.

Pro Tips

• Always use gross income, not net. Many people mistakenly enter their take-home pay after taxes, but Arkansas law requires gross income before any deductions except those specifically allowed (health insurance, prior support, mandatory retirement). Using net income will significantly understate your obligation or entitlement.
• Include all sources of income, including side hustles, bonuses, and overtime if it is regular and predictable. If you receive a yearly bonus, divide it by 12 to get a monthly average. Courts consider consistent overtime and second jobs as part of earning capacity, even if the income is not guaranteed every month.
• For shared custody calculations, accurately count the overnights. Arkansas defines shared custody as each parent having the child at least 146 overnights per year (40%). Use a calendar to count actual nights, not just weekends. Even a few extra overnights can shift the calculation from sole to shared custody, drastically changing the support amount.
• Document all health insurance costs. Only the portion of the premium that covers the child(ren) is deductible. If your employer covers the full family premium, you may need to determine the "child-only" cost. Use the employer’s COBRA rate or the difference between single and family coverage as a proxy.

Common Mistakes to Avoid

• Forgetting to Include Prior Child Support Orders: If you are already paying court-ordered support for a child from a previous relationship, you must deduct that amount from your gross income before calculating support for the current case. Failing to do so will overstate your ability to pay and could result in an unfairly high obligation. The calculator includes a field for this; use it.
• Ignoring Self-Employment Income Properly: Self-employed parents often report net income after business expenses, but they may forget to add back depreciation or other non-cash deductions that Arkansas law considers as available income. The court may also impute income if the business is underperforming relative to the parent’s earning capacity. Use Schedule C net profit as a starting point, but be prepared to justify expenses.
• Assuming the Calculator Result is Final: The calculator provides an estimate based on standard guidelines. Arkansas courts have discretion to deviate from the schedule if the result is unjust or inappropriate (e.g., if a child has extraordinary medical needs, or if a parent is voluntarily unemployed). Always treat the calculator result as a starting point for negotiation, not a final court order.
