Child Support Calculator in Oklahoma: What You Should Know
Oklahoma uses the Income Shares Model under Title 43 of the state statutes, combining both parents' gross monthly incomes to set the base support obligation. The obligation is divided between the parents in proportion to their incomes, and Oklahoma applies a parenting time adjustment once the paying parent passes a set number of overnights per year. Health insurance and childcare costs are added to the base figure. There is no statutory income cap, though the guideline schedule has a top figure above which the court uses discretion.
Key point: Oklahoma follows the Income Shares Model on gross income and applies a parenting time adjustment once the paying parent reaches a set number of annual overnights.

Child Support in Oklahoma - Frequently Asked Questions
How is child support calculated in Oklahoma?
Oklahoma uses the Income Shares Model to calculate child support. Both parents' gross incomes are combined, and each parent's share of the total obligation is proportional to their share of the combined income.
Can child support be modified in Oklahoma?
Yes. Either parent can request a child support modification if there has been a substantial change in circumstances, such as a significant change in income, change in custody arrangements, or changes in the child's needs. Courts in Oklahoma typically require a change of at least 15-20% in the support amount to justify modification.
Does custody arrangement affect child support in Oklahoma?
Yes. Parenting time is a significant factor in child support calculations. When a parent has the children for a substantial portion of time (typically 40% or more overnights per year), child support is adjusted to reflect the additional direct costs that parent bears.
Is there an income cap for child support in Oklahoma?
Oklahoma does not set a specific income cap in its child support formula. However, courts have discretion to deviate from the guideline amount in cases with very high incomes.
How long does child support last in Oklahoma?
Child support in Oklahoma typically continues until the child turns 18 or graduates from high school, whichever is later. Support may continue longer if the child has a disability or if the parents agree to extend support for college expenses.
