Virginia Income Shares Model
Virginia uses the Income Shares model established by Virginia Code § 20-108.2, calculating child support based on both parents' Adjusted Gross Income (AGI). The critical 90-day custody thresholddetermines whether sole custody or shared custody formulas apply.
AGI starts with gross income, then deducts spousal support paid to others and support for other children. The 90-day threshold creates a fundamental shift: shared custody uses a 1.5x multiplier with cross-credit calculations.

Frequently Asked Questions
How does Virginia's 90-day custody threshold work?
When both parents have 90+ overnights per year, Virginia changes from simple pro-rata allocation to complex shared custody formula with 1.5x multiplier, recognizing dual household costs. This threshold creates a dramatic shift in calculation methodology.
How does Virginia calculate Adjusted Gross Income (AGI)?
Virginia starts with gross income (all sources), then deducts court-ordered spousal support paid to others and child support for other children. It also accounts for other children in each household by applying theoretical support obligations, ensuring fair calculation of available resources.
How accurate is this Virginia calculator?
Our calculator implements current Virginia Code § 20-108.2 and official worksheets (DC-637, DC-640, DC-638) to provide accurate estimates based on state guidelines. Results match court-approved software for preliminary planning purposes.
What's the difference between sole and shared custody calculations?
Sole custody (under 90 days) uses simple pro-rata allocation. Shared custody (90+ days each) applies a 1.5x multiplier to basic obligation and uses cross-credit offset formula, recognizing higher costs of maintaining two households.
Do courts accept these calculations?
While courts use the same statutory formulas, actual orders may vary based on specific circumstances and judicial discretion. Our calculations provide accurate estimates for planning purposes, but should be verified with a qualified Virginia family law attorney.
