Worked Example

Let's calculate child support for a scenario where:

Paying parent's income: $60,000 per year
Number of children: 1
Child support percentage: 17%

Weekly Child Support = ($60,000 × 0.17) ÷ 52 = $183.65

Monthly Child Support = $183.65 × 4.33 = $793.33

Annual Child Support = $793.33 × 12 = $9,519.96

In this example, the child support would be approximately $183.65 per week, $793.33 per month, or $9,519.96 per year.
