Formula and Assumptions

The 2017 Ontario spousal support formula is based on:

Support = (Paying spouse's gross income × Percentage factor) ÷ 12 Percentage factor = 25% - (5% × Number of children) - (1% × Years of marriage)

Key assumptions:

Gross income is annual income before taxes
Maximum support is 50% of the paying spouse's income
Minimum support is $100 per month
Support is typically paid monthly

Worked Example

Example calculation for a couple with:

Paying spouse income: $80,000
1 child
5 years of marriage

Percentage factor = 25% - (5% × 1) - (1% × 5) = 19% Support = ($80,000 × 19%) ÷ 12 = $1,200 ÷ 12 = $100/month

This example shows the minimum support amount of $100 per month.
