Ontario Child & Spousal Support Calculator

Estimate child support under the Federal Child Support Guidelines and spousal support under the Spousal Support Advisory Guidelines (SSAG) — together, because child support directly affects what spousal support should be.

For estimation purposes only. Not legal advice. Actual amounts are determined by a court or mutual agreement.

👶

Child Support (FCG)

Set by the Federal Child Support Guidelines based on the payor's income, number of children, and province. Not negotiable below the table amount without court approval.

💍

Spousal Support (SSAG)

The Spousal Support Advisory Guidelines provide a range — not a fixed number. Courts weigh the length of marriage, roles during marriage, and economic disadvantage.

🔗

Why They Interact

Child support is paid first and reduces the payor's available income. The SSAG “with child support” formula uses Net Disposable Income to set a fair spousal amount after CS is deducted.

⚖️

Court Discretion

Judges can depart from SSAG ranges based on compensatory claims, roles during marriage, health, and ability to become self-sufficient. These are estimates, not guarantees.
