What counts as parenting time
Most states measure parenting time in overnights per year. A typical "every other weekend" schedule equals roughly 14–20% of overnights. An extended schedule with one weekday dinner and overnight may approach 25–30%. A 2-2-3 or week-on/week-off schedule is 50%.
The breakeven point
As parenting time approaches 50%, the parenting-time credit grows. In income shares states, the higher-earning parent typically still pays some support to the lower-earning parent even at 50/50, but the amount is much smaller than at 0% custody.
