How these calculations work
Child Support (FCSG)
Child support in Canada is determined by the Federal Child Support Guidelines(SOR/97-175). The amount is based on the payor's gross income, the number of children, and the province or territory of residence. This calculator uses 2025 table values and linear interpolation between table breakpoints.
For incomes above $150,000, courts may order additional amounts under Section 4. Quebec uses its own provincial model.
Spousal Support (SSAG)
This calculator uses the SSAG Without Child formula: support ranges from 1.5%–2.0% of gross income difference per year of cohabitation, divided by 12. Duration ranges from 0.5× to 1.0× years of cohabitation. After 20 years, support becomes indefinite.
If there are dependent children, the SSAG With Child formula applies and produces different results based on net disposable income sharing.
Common questions
Is this calculator accurate?
This tool provides estimates based on simplified guideline formulas. Actual support orders depend on many factors a court will consider — income determination, parenting time, special expenses, credibility of financial disclosure, and judicial discretion. Always verify with a family lawyer before relying on these numbers.
Which provinces are supported?
All 13 Canadian provinces and territories are supported. Most use the Federal Child Support Guidelines. Quebec uses a different model based on net incomes and parenting time — the estimate shown for Quebec is approximate.
What's the difference between FCSG and SSAG?
The Federal Child Support Guidelines (FCSG) set mandatory table amounts for child support based on income. The Spousal Support Advisory Guidelines (SSAG) provide advisory ranges for spousal support — they are not legally binding but are widely used by courts and counsel as a starting point.
What if the payor earns over $150,000?
The child support tables only go to $150,000. For higher incomes, Section 4 of the FCSG applies and courts have discretion to order more. The amount at $150K is shown as a floor.
