Formula Used

The Ontario Child Support Guidelines use a formula to determine the monthly child support payment. The basic formula is:

Monthly Child Support = (Paying Parent's Income - Receiving Parent's Income) × Percentage × Number of Children

The percentage is determined based on the difference between the two parents' incomes. For example, if the paying parent earns $5,000 and the receiving parent earns $3,000, the difference is $2,000, which corresponds to a certain percentage.

The exact percentage is based on a table provided by the Ontario government. For more detailed information, you can refer to the official Ontario Child Support Guidelines.

Worked Example

Let's look at an example to understand how the calculation works.

Example Scenario

Paying Parent's Income: $4,500 per month
Receiving Parent's Income: $2,800 per month
Number of Children: 2

The difference between the two incomes is $1,700 per month. According to the Ontario Child Support Guidelines, a $1,700 difference corresponds to a 25% payment.

Monthly Child Support = ($4,500 - $2,800) × 25% × 2 = $1,700 × 0.25 × 2 = $850

Therefore, the monthly child support payment for this scenario is $850.
