This is an estimate, not a court order. Figures marked Verified use your state's exact current statutory percentages. Figures marked Estimated use a standard Income-Shares approximation because that state publishes its guideline as a detailed table rather than a simple formula - your actual number may differ. Guideline amounts, caps, and deductions change over time and courts can deviate from the guideline. Always confirm with your state's child support agency or a licensed family law attorney before relying on this for a filing.
