The official Rhode Island calculator
Rhode Island Family Court guidelines use both parents' monthly gross income, minus allowed deductions. The combined adjusted income is matched to the child support table, work-related child care is added, and each parent's share is set by his or her percentage of the combined income. The paying parent's share becomes the recommended order, and cash medical support can be added.

Health insurance in Rhode Island
Every Family Court support order must require one or both parents to get health insurance for the child when it is available through work at no cost or reasonable cost; reasonable cost is defined in the guidelines. A National Medical Support Notice goes to the employer.

The model in plain words
Income shares means the child should get what the parents would spend if they lived together. Both incomes are combined, and each parent's share of the total sets their part.
Every state must have one set of child support guidelines, review them at least every 4 years, and use the guideline amount unless a written finding says it would be unjust.
Law: 45 CFR 302.56
