This calculator helps you determine Ontario child support payments when parents share custody. It considers both parents' incomes, expenses, and custody arrangements to provide an accurate estimate of monthly support.
How the Calculator Works
Ontario's child support guidelines are based on a formula that considers both parents' incomes and expenses. The calculator uses these guidelines to estimate monthly child support payments when parents share custody.
The Ontario Child Support Guidelines use a complex formula that includes:
- Both parents' gross incomes
- Deductions for certain expenses
- Adjustments for custody arrangements
- Special needs considerations
The calculator simplifies this process by asking for key information and applying the official guidelines to provide an estimate. Remember that actual court orders may vary based on specific circumstances.
Formula Used
The Ontario Child Support Guidelines use the following formula to calculate monthly support:
Monthly Support = [(Parent 1 Income - Deductions) + (Parent 2 Income - Deductions)] × Percentage × Custody Factor
Where:
- Parent 1 Income and Parent 2 Income are the gross annual incomes of each parent
- Deductions include standard expenses like health insurance, RRSP contributions, and union dues
- Percentage is based on the number of children and their ages
- Custody Factor adjusts for shared custody arrangements
The exact calculation involves multiple steps and tables provided by the Ontario government. This calculator uses the most current guidelines to provide an accurate estimate.
Worked Example
Let's look at an example to see how the calculator works:
Example Scenario
Parent 1 earns $60,000/year
Parent 2 earns $50,000/year
Both parents share custody equally
One child under age 12
The calculator would:
- Calculate net incomes after standard deductions
- Apply the percentage for one child under 12
- Adjust for shared custody (50% factor)
- Provide the estimated monthly support amount
For this example, the calculator would estimate approximately $350 per month in child support.
