This number is a snapshot. Child support depends on parenting time, and parenting time drifts — swapped weekends, changed holidays, summer schedules. Vireo keeps the custody calendar, messages and shared expenses in one timestamped record, so what actually happened is never a matter of memory.

Convert each parent's monthly gross income to net and SOLA income; compute net-income shares; base primary support is $455 per child; add allowed child care and children's health insurance/cash medical; add SOLA equal to 10% per child (30% maximum) of combined remaining SOLA income after primary need; allocate by net-income share and subtract direct credits.
How income is counted: Monthly gross income from all sources, with detailed inclusions and exclusions in section V.J; the Table of Incomes converts taxable gross income to monthly net and SOLA income. Non-taxable and net self-employment income use separate appendices.
