How to Calculate Child Support in Ontario

The Ontario Child Support Guidelines provide a framework for calculating child support payments. The amount is determined based on:

The combined income of both parents
The number of children and their ages
Each parent's living arrangements
Special expenses for the children

Step-by-Step Calculation Process

Calculate the combined income of both parents
Determine the basic child support amount using the income tables
Adjust for the number of children and their ages
Add any special expenses for the children
Calculate the final child support amount

Important Notes

The actual child support amount may differ from the calculated amount based on the Ontario Child Support Guidelines. Court orders take precedence over these calculations.

Formula Used

The basic child support amount is calculated using the following formula:

Child Support Formula

Basic Child Support = (Combined Income × Percentage from Income Table) + Special Expenses

Final Child Support = Basic Child Support × Adjustment Factors

The percentage from the income table is determined based on the combined income of both parents. Adjustment factors consider the number of children, their ages, and living arrangements.

Worked Examples

Example 1: Two Parents, One Child

Parent 1 income: $50,000
Parent 2 income: $60,000
Combined income: $110,000

Using the income table, a combined income of $110,000 results in a 25% child support percentage.

Basic child support = ($110,000 × 25%) = $27,500

After adjustments for one child: $27,500

Example 2: Two Parents, Two Children

Parent 1 income: $70,000
Parent 2 income: $80,000
Combined income: $150,000

Using the income table, a combined income of $150,000 results in a 28% child support percentage.

Basic child support = ($150,000 × 28%) = $42,000

After adjustments for two children: $42,000
