How to Calculate Child Support in Ontario

Child Support = (Parent's Income × Percentage) - (Child's Expenses × Percentage)

The percentage is determined by the number of children and their ages.

Factors That Affect Child Support

Several factors influence the amount of child support calculated:

Income: Higher income generally results in higher support payments
Number of children: More children typically mean higher support amounts
Custody arrangement: Shared custody may result in different calculations than sole custody
Child's expenses: Special needs or additional costs can affect the calculation
Special circumstances: Unique situations may require adjustments to the standard formula

Important Note

The calculator provides estimates based on guidelines. Actual court orders may differ based on specific circumstances and legal interpretations.

Child Support for Shared Custody

When parents share custody, the child support calculation differs from sole custody arrangements. The Ontario Child Support Guidelines account for:

Time each parent spends with the child
Each parent's financial responsibility
Special needs of the child

Our calculator includes options for different custody percentages to help you understand how this affects the support amount.

Shared Custody Formula

Child Support = (Parent's Income × Percentage) - (Child's Expenses × Percentage) × (Custody Percentage / 100)

Special Circumstances

In some cases, the standard child support calculation may not apply. Special circumstances include:

Parents with disabilities
Children with special needs
Parents who are self-employed
Parents with irregular income
Parents who are in the military

For these situations, the Ontario Child Support Guidelines allow for adjustments to the standard calculation. Our calculator includes options for some of these special circumstances to provide more accurate estimates.
