Official Formula
The Ontario Child Support Guidelines use a formula to determine child support payments. The basic calculation is:
Monthly Child Support = (Total Annual Income ÷ 12) × (Weeks with Non-Custodial Parent ÷ 52) × (1 + 0.02 × (Number of Children - 1))
This formula accounts for:
- The total income of both parents
- The percentage of time each parent spends with the child
- Any additional children in the household
The Ontario government provides additional adjustments for factors like education expenses, medical expenses, and special needs.
Worked Example
Let's calculate child support for a scenario where:
- Parent 1 income: $60,000/year
- Parent 2 income: $40,000/year
- 2 children
- Child spends 30 weeks with Parent 1 and 22 weeks with Parent 2
Using the formula:
Monthly Child Support = (($60,000 + $40,000) ÷ 12) × (22 ÷ 52) × (1 + 0.02 × (2 - 1))
= ($100,000 ÷ 12) × 0.423 × 1.02
= $8,333.33 × 0.423 × 1.02
= $3,552.08 per month
The calculator would display $3,552.08 as the monthly child support payment for this scenario.
