Worked Examples
Let's look at two examples to understand how the child support calculation works.
Example 1: Single Child, Shared Custody
Parent A has a net income of $50,000 and Parent B has a net income of $40,000. They share custody of one child.
Using the Ontario Child Support Guidelines:

Example 2: Two Children, Primary Custody
Parent A has a net income of $75,000 and Parent B has a net income of $60,000. Parent A has primary custody of two children.
Using the Ontario Child Support Guidelines:
