Washington, D.C. Child Support Calculator

Washington, D.C. uses a hybrid model to calculate child support—combining aspects of both the income shares and percentage of income models. This allows the courts greater flexibility in tailoring support obligations to meet a child’s individual needs.

When a child has special needs, the courts may deviate from standard support guidelines to cover extraordinary expenses such as:

  • Ongoing medical treatment
  • Therapy or counseling services
  • Special education programs
  • Assistive technologies or in-home care

These considerations ensure the support order accurately reflects the financial demands of caring for a child with unique requirements.

Frequently Asked Questions

Washington, D.C. uses a hybrid model that combines elements of both the income shares and percentage of income models. This approach considers both parents’ incomes, the number of children, and each parent’s share of caregiving time. The goal is to allocate financial responsibility fairly between parents while ensuring the child’s needs are fully met.

Courts in D.C. take several factors into account when determining support obligations, including:

  • Each parent’s gross monthly income

  • The number of children supported

  • Custody arrangements and the amount of time spent with each parent

  • Health insurance, childcare, and educational expenses

  • Any extraordinary needs related to the child’s health or development

When a child has special needs, Washington, D.C. courts may deviate from the standard support guidelines to ensure sufficient funding for:

  • Ongoing medical treatments and therapies

  • Special education or individualized learning programs

  • Counseling and mental health services

  • Assistive devices, adaptive technologies, or in-home care
    These deviations are designed to reflect the true financial costs of caring for a child with unique needs.
