How to Calculate Ontario Child Support for Joint Custody

The Ontario Child Support Guidelines (OCSG) determine how much child support should be paid. For joint custody arrangements, the calculation considers both parents' incomes and the number of children. Here's a step-by-step guide to calculating child support:

Step 1: Determine Gross Income

Calculate the gross income of both parents. This includes all sources of income before taxes and deductions. Common income sources include wages, salaries, self-employment income, and investment income.

Step 2: Calculate Net Income

Subtract allowable deductions from the gross income to find the net income. Common deductions include:

• RRSP contributions
• Union dues
• Workplace expenses
• Health and dental benefits
• Retirement contributions

Step 3: Apply Child Support Formula

The Ontario Child Support Guidelines use a formula to determine the child support amount. The formula considers the net income of both parents and the number of children. The basic formula is:

Step 4: Adjust for Special Factors

The child support amount may be adjusted based on special factors such as:

• Number of children
• Parental income
• Childcare expenses
• Medical expenses
• Educational expenses

Step 5: Review and Confirm

Once you have calculated the child support amount, review it with a legal professional to ensure accuracy. The final amount may be adjusted based on specific circumstances.

Child Support Formula

The Ontario Child Support Guidelines use a specific formula to determine the child support amount. The formula considers the net income of both parents and the number of children. Here's a detailed breakdown of the formula:

The child support rate is determined based on the combined net income of both parents. The rates are as follows:

• Up to $100,000: 16.5%
• $100,001 to $150,000: 15.5%
• Over $150,000: 14.5%

For example, if the combined net income is $120,000 and there is one child, the child support amount would be:

Worked Example

Let's walk through a worked example to illustrate how to calculate child support for joint custody in Ontario.

Example Scenario

Parent 1 has a net income of $80,000, and Parent 2 has a net income of $60,000. There is one child.

Step 1: Calculate Combined Net Income

Combined Net Income = Parent 1's Net Income + Parent 2's Net Income = $80,000 + $60,000 = $140,000

Step 2: Determine Child Support Rate

Since the combined net income is between $100,001 and $150,000, the child support rate is 15.5%.

Step 3: Calculate Child Support Amount

Child Support = Combined Net Income × Child Support Rate × Number of Children = $140,000 × 15.5% × 1 = $21,700

Key Factors Affecting Child Support

Several factors can affect the amount of child support calculated in Ontario. Understanding these factors can help you determine the most accurate child support amount.

The number of children is a significant factor in determining child support. The more children there are, the higher the child support amount will be.

Parental Income

The income of both parents is considered when calculating child support. Higher incomes generally result in higher child support amounts.
