Virginia's rule on how child support is calculated turns on a feature the national template does not capture: Virginia uses the Income shares and measures income as gross income. Virginia’s guideline tables use combined monthly gross income to set a schedule obligation allocated by income share. Shared-custody formulas apply when a parent has the child more than 90 days; health-care and childcare costs are add-ons. The controlling authority is Va. Code §§ 20-108.1, 20-108.2. Support generally ends when Support generally ends at 18, or 19 if still in high school full-time and not self-supporting. Modification: Material change in circumstances; guideline recalculation typically anchors the petition.
Key takeaways
- Virginia follows the Income shares model for presumptive child support.
- Income is generally measured using gross income, then allocated under Va. Code §§ 20-108.1, 20-108.2.
- Guideline amounts are presumptive, not automatic — courts may deviate when the facts justify it.
- Support generally ends at 18, or 19 if still in high school full-time and not self-supporting.
- Either parent can seek modification when material change in circumstances; guideline recalculation typically anchors the petition..
- Read the companion guide: Virginia alimony / spousal support.
Worked example under Virginia law
The illustration below uses only rules already stated for Virginia. It is a research hypothetical, not a prediction of what a court will do.
Two parents in Virginia need a presumptive child-support figure and may have facts that justify a departure.
- Measure guideline income as gross income under Va. Code §§ 20-108.1, 20-108.2.
- Apply the Income shares: Virginia’s guideline tables use combined monthly gross income to set a schedule obligation allocated by income share. Shared-custody formulas apply when a parent has the child more than 90 days; health-care and childcare costs are add-ons.
- Test deviation: Statutory deviation factors include imputed income issues, travel costs, and other equitable considerations under § 20-108.1.
- If circumstances later change: Material change in circumstances; guideline recalculation typically anchors the petition.
The enforceable number is the Virginia guideline result under Va. Code §§ 20-108.1, 20-108.2, plus any deviation findings. Division of Child Support Enforcement uses income withholding, intercepts, and contempt.
Statutory framework and guideline model
Virginia's child support system is built around Va. Code §§ 20-108.1, 20-108.2. Under the income shares, Virginia’s guideline tables use combined monthly gross income to set a schedule obligation allocated by income share. Shared-custody formulas apply when a parent has the child more than 90 days; health-care and childcare costs are add-ons.
Federal law requires every state to maintain presumptive guidelines and to review them at least every four years (42 U.S.C. § 667). Confirm the latest Virginia schedule or worksheet before relying on any online calculator.
How child support is calculated in Virginia
- Identify each parent's guideline income using gross income as defined in Va. Code §§ 20-108.1, 20-108.2 and the accompanying worksheets or administrative rules.
- Apply the income shares — whether that means a combined-income schedule, an obligor percentage table, or a Melson-style self-support reserve plus primary obligation.
- Allocate add-ons such as health insurance premiums, unreimbursed medical expenses, and work-related child care according to Virginia practice.
- Consider parenting time adjustments where the guidelines or case law authorize a credit or shared-custody formula.
- Test for deviation if a strict guideline result would be unjust or inappropriate on the record.
Online calculators can illustrate ranges, but only the controlling statute, guidelines, and court findings produce an enforceable order.
Deviation from the guidelines
Statutory deviation factors include imputed income issues, travel costs, and other equitable considerations under § 20-108.1.
When a court departs from the presumptive amount, Virginia practice generally requires findings that explain why the guideline figure is unjust or inappropriate and what amount better serves the child's needs. Those findings matter on appeal and in later modification proceedings.
Modification of child support
Material change in circumstances; guideline recalculation typically anchors the petition.
A parent seeking a change typically must show that circumstances after the prior order make the existing award inequitable. Common triggers include job loss, substantial income changes, a new parenting-time schedule, emancipation of a child, or extraordinary medical needs. Retroactivity and temporary relief rules are statute-specific — check Va. Code §§ 20-108.1, 20-108.2 and local family-division procedures.
Enforcement in Virginia
Division of Child Support Enforcement uses income withholding, intercepts, and contempt.
Interstate cases often implicate UIFSA. Income withholding, contempt, license suspension, and tax-refund intercept remain core tools nationwide, but the Virginia child support agency and clerk of court procedures control day-to-day collection.
When child support ends
In Virginia, Support generally ends at 18, or 19 if still in high school full-time and not self-supporting. Orders may extend for disability, secondary education, or other statutory grounds where the statute allows. Always read the judgment language — agreed orders sometimes set a different end date or require a notice of emancipation.

Frequently asked questions
How is child support calculated in Virginia?
Virginia uses the income shares under Va. Code §§ 20-108.1, 20-108.2. Courts start with gross income, apply the guideline schedule or percentage, allocate add-ons, and may deviate with findings when the presumptive amount is unjust.
What income counts for Virginia child support?
Guideline income generally tracks gross income as defined by Va. Code §§ 20-108.1, 20-108.2 and the worksheets. Wages, self-employment income, bonuses, and certain benefits are commonly included; exact deductions and exclusions are statute-specific.
Can Virginia courts order more or less than the guideline amount?
Yes. Guideline support is presumptive. Judges may deviate when the record shows the guideline result is unjust or inappropriate, typically with written findings explaining the departure.
How do I modify a Virginia child support order?
Material change in circumstances; guideline recalculation typically anchors the petition. File in the court with continuing jurisdiction (or follow UIFSA for interstate cases) and support the request with current financial evidence.
When does child support end in Virginia?
