This calculator provides an estimate based on the Ontario Child Support Guidelines. Actual child support amounts may vary based on specific circumstances and court decisions.

Formula Used

The Ontario Child Support Guidelines use a formula to calculate child support based on income and custody arrangement. The basic formula is:

Child Support = (Parent's Income × Custody Factor) - (Spouse's Income × Custody Factor) × Number of Children

The custody factor is determined by the number of nights each parent has custody. For split custody, the formula adjusts the calculation based on the proportion of nights each parent has the child.

Example Calculation

If Parent A earns $5,000/month, Parent B earns $4,000/month, and Parent A has custody 180 nights/year while Parent B has custody 184 nights/year, the calculation would be:

Custody Factor = (180 / (180 + 184)) = 0.494

Child Support = (($5,000 - $4,000) × 0.494) × 1 = $494/month

Worked Example

Let's walk through a complete example to see how the calculator works.

Scenario

Parent A income: $4,500/month
Parent B income: $3,800/month
Number of children: 2
Parent A has custody 182 nights/year
Parent B has custody 182 nights/year

Calculation Steps

Calculate the custody factor: (182 / (182 + 182)) = 0.5
Calculate the income difference: $4,500 - $3,800 = $700
Multiply by custody factor: $700 × 0.5 = $350
Multiply by number of children: $350 × 2 = $700

The estimated monthly child support payment in this scenario would be $700.

Note: This is an estimate. Actual child support amounts may differ based on specific circumstances and court decisions.
