Child support calculator & insurance

To figure out child support with the calculator it asks how much insurance is paid for the children. Does this include the total cost for a family coverage, or what is in addition from a single person coverage to the family coverage which includes the children???

You need the additional amount paid for the child.

The judge in my case took the total cost of my premium and divided by how may people are covered. She then subtracted my portion. What’s awful is that she included my step-children in the calculation and subtracted their costs too.
