The child support guideline calculation necessarily factors in the amount of time that a parent has with their child or children. When a parent spends more time with their child, the expectation is that under the guidelines, their child support calculation will be lower. It is not necessarily a one-for-one ratio under the guidelines, and it is always better to consult with an experienced family law attorney to be able to determine whether, based on the facts of the case and the incomes of the parties, the child support amount can be reduced with an increase in the time-sharing schedule.
