Shared Custody Child Support Calculator Ontario

Reviewed by Calculator Editorial Team

This calculator helps you determine child support payments in Ontario for shared custody arrangements. It follows the guidelines set by the Ontario government to provide accurate estimates based on your financial situation and the number of children involved.

How the Calculator Works

The Ontario Child Support Guidelines calculate child support based on the income of both parents and the number of children involved. The calculator uses these guidelines to provide an estimate of monthly child support payments.

Key Factors Considered

  • Gross income of both parents
  • Number of children
  • Special expenses (if applicable)
  • Deductions for certain expenses

How to Use the Calculator

  1. Enter your gross monthly income
  2. Enter your spouse's gross monthly income
  3. Select the number of children
  4. Check if you have any special expenses
  5. Click "Calculate" to see your estimated child support

Formula Used

The Ontario Child Support Guidelines use a complex formula to calculate child support. The simplified version used in this calculator is:

Child Support = (Parent 1 Income + Parent 2 Income) × Child Support Rate - Deductions

The child support rate varies based on the number of children and the parents' combined income. Special expenses may increase the amount, while certain deductions may reduce it.

Worked Example

Let's calculate child support for a family with two children where:

  • Parent 1 income: $4,000/month
  • Parent 2 income: $3,500/month
  • Number of children: 2
  • No special expenses

Based on the Ontario Child Support Guidelines, the estimated monthly child support for this scenario would be approximately $1,200.

This example shows how the calculator applies the guidelines to provide a realistic estimate of child support payments.

Important Considerations

While this calculator provides a good estimate, it's important to remember:

  • The actual child support amount may vary based on specific circumstances
  • Special expenses can significantly increase the amount
  • Deductions can reduce the amount owed
  • Court orders may differ from the guidelines

For precise calculations, it's recommended to consult with a family lawyer or use the official Ontario Child Support Guidelines.
