Work-related child care, less the federal child care credit, is added to the basic obligation and shared by income. A noncustodial parent whose children are on RIte Care or on the custodial parent's insurance pays a cash medical contribution of 5% of gross income, capped at the premium.
How Rhode Island works it out
Rhode Island uses the income shares model: the schedule gives the basic obligation for the parents' combined monthly adjusted gross income, and each parent pays their percentage share.
Gross income from almost all sources counts, before taxes, including alimony received. Required deductions come off first: support paid under other orders, the children's health insurance premium or cash medical, half the schedule amount for other children living with a parent, and each parent's share of net child care.
Support is not reduced for ordinary parenting time. With shared placement, when each parent has at least 179 overnights a year, each parent's share of the total obligation is worked out and the parent with the larger amount pays the difference.
