Child support in Jacksonville: how it is calculated
Child support in Jacksonville is set by Florida's statewide guidelines — Duval County courts apply the same table as every other county. Here is the calculation, with the statute it comes from.
Where a Jacksonville case goes
A Jacksonville case is filed in the Florida court for Duval County, which applies the state guideline below. Local practice affects timing and paperwork, not the guideline amount. Jacksonville has about 1,009,833 residents (Census Bureau, 2024 estimate).

Does Jacksonville have its own rule?
No. Fla. Stat. § 61.30 applies across Florida, so a case from Jacksonville is decided by the same numbers as one filed anywhere else in the state. What changes locally is the courthouse, the clerk's procedure and how long the docket takes — not the amount.
What the statute says
Fla. Stat. § 61.30 — Florida child support guidelines (income shares schedule). Florida uses combined monthly NET income (after taxes, health insurance, mandatory dues and other § 61.30(3) deductions). The schedule runs from $800 to $10,000 of combined net income in $50 steps; above $10,000 the statute adds a percentage of the excess (5% for one child up to 12.5% for six). Child-care costs and the child's health insurance are added on top and split by income share, and overnights above 20% of the year trigger the gross-up adjustment in § 61.30(11)(b).
