How Oklahoma Calculates Child Support

Oklahoma calculates child support using the Income Shares Model as defined in 43 O.S. §118. Both parents' adjusted gross incomes are combined to determine the total support obligation from the state schedule. Each parent's share is then allocated proportionally based on their percentage of the combined income.

Health insurance premiums for the child, childcare costs, and extraordinary medical expenses are added to the base obligation and shared proportionally between the parents. Oklahoma also maintains a self-support reserve of $1,038 per month (2024) to ensure the obligor retains enough for their own basic needs.

Oklahoma provides shared custody adjustments and low-income provisions for obligors with limited income. Courts may deviate from the guideline amount when justified by the specific circumstances of the case.
