How Child Support is Calculated in Oklahoma


Child support payments in Oklahoma are calculated using the income shares category method. Payments depend on the combined incomes of the parents as well as the number of children. A larger combined income or more children usually means greater payments.

The amount paid or received by an individual parent also depends on their income percentage. The higher your percentage of combined parent income, the more you pay or less you receive.

Payments are also affected by which parenting time category applies. Payments may be lower because of a "shared" (fairly equal) care arrangement.

Oklahomans paying the most child support have high incomes and limited parenting time. Conversely, the biggest receivers are parents who (a) work little (b) have their kids most of the time and (c) have a high earner as the other parent.

Oklahoma law does not give the court much leeway to deviate from the child support guidelines. The actual amount the judge orders is usually close to the calculated amount.

To estimate the amount of child support to be awarded, you can use the child support calculator on the Oklahoma Department of Human Services website. You can also obtain a copy of the Oklahoma Child Support Guidelines there and download instructions on how to use the calculator.

The number of overnights the child(ren) stay with each parent is included in the calculation. In sum, the more overnights the child(ren) stay with a parent the less that parent’s child support obligation will be.
