Estimate child support using an income shares approach with parenting time.
Income shares models compute what both parents together would spend on the children, then apportion it by income. Substantial parenting time reduces the transfer because that parent already meets costs directly. Actual formulas vary greatly by jurisdiction and many apply thresholds, caps and shared-care cliffs that change the result sharply at particular parenting time percentages.

Obligation = combined income × rate for the child count, apportioned by income share
