Formula Used

2 children: 25% of the income difference
3 or more children: 30% of the income difference

The result is then divided by 12 to get the monthly amount.

Income figures are annual gross income
Support is calculated for a 12-month period
The calculation follows the 2021 Ontario Family Law Act guidelines
This is an estimate and may not reflect actual court-ordered support amounts

Worked Example

Example calculation for a couple with the following details:

Paying spouse income: $80,000
Receiving spouse income: $40,000
Number of children: 2

Calculation steps:

Income difference: $80,000 - $40,000 = $40,000
Support factor for 2 children: 25%
Annual support amount: $40,000 × 25% = $10,000
Monthly support amount: $10,000 ÷ 12 = $833.33

The estimated monthly support amount would be $833.33.
