Understanding Virginia's Child Support System
Virginia uses the Income Shares model which assumes children should receive the same proportion of parental income as if the family remained together.
- Combines both parents' adjusted gross incomes
- Uses state economic data to determine support obligation
- Allocates obligation based on income proportions
- Accounts for custody time and additional expenses
Virginia's unique 90-day threshold creates a dramatic shift in calculation methodology when both parents have substantial custody time.
Sole Custody (<90 Days)
- • Simple pro-rata allocation
- • Standard Income Shares calculation
- • NCP pays percentage share to CP
Shared Custody (90+ Days Each)
- • Basic obligation × 1.5 multiplier
- • Cross-credit offset formula
- • Recognizes dual household expenses

Real User Reviews - Virginia Child Support Calculator
"The 90-day custody threshold explanation was crucial! I had 95 overnight visits and had no idea it triggered the shared custody formula with 1.5x multiplier."
"Income Shares model is complex but this calculator handled it perfectly. Combined income $8,500, used DC-640 worksheet for shared custody - matches court exactly."
"Had 89 days vs 276 split custody. Calculator properly used DC-637 sole custody worksheet instead of shared. The 90-day threshold really matters!"
