Rhode Island sets child support with a written guideline, and the official worksheet is how the math gets shown to the judge. Both parents' income normally goes into the calculation, along with things like health insurance for the children and child care costs.
The official guideline materials for Rhode Island are linked below, together with the verified support documents and the financial paperwork the court usually asks both sides to file. Our own calculator can give you a working estimate before you fill in the official worksheet.

Through the state's written guideline, applied on the official worksheet. The guideline uses income and a defined list of add-ons rather than a judge's rough guess, so filling the worksheet in honestly is the single most useful thing you can do. Open the official Rhode Island guideline materials above for the exact method.
A judge can depart from the guideline in some situations, but the order normally has to explain why. Start from the guideline number and be ready to say plainly what makes your case different.
