Worked Example
Let's calculate child support for a family with joint custody:
Family Details
- Parent 1 income: $60,000/year
- Parent 2 income: $50,000/year
- Number of children: 2
- Child ages: 5 and 8
- Custody arrangement: 50/50 split
Calculation Steps
- Total income: $60,000 + $50,000 = $110,000
- Apply percentage (from Ontario tables): 18.5%
- Child support before needs: $110,000 × 0.185 = $20,350
- Subtract child's needs (from Ontario tables): $12,000
- Final child support: $20,350 - $12,000 = $8,350
- Adjust for joint custody: $8,350 × 0.5 = $4,175 per parent
Result
Each parent should pay $4,175 per month in child support.
