Estimated Results
These are estimates only.
Your actual amount may differ based on Section 7 expenses, special circumstances, and court discretion.
Based on the Ontario Child Support Table under the Federal Child Support Guidelines. Updated 2022 table values used. Section 7 special/extraordinary expenses (childcare, medical, extracurricular) are not included in this estimate.
How this works — Child Support formula
Ontario Table Lookup
Monthly child support is determined by looking up the payor's gross annual income in the Ontario Child Support Guidelines Table. The amount increases with income and number of children.
Sole vs. Shared Custody
Sole/primary custody (one parent has the child more than 60% of the time): the payor pays the straight Table amount.
Shared custody (each parent has at least 40% of parenting time): each parent's Table amount is calculated separately, then the lower is subtracted from the higher. The difference is paid by the higher-income parent, subject to court discretion based on actual costs.
What's Not Included
Section 7 "special or extraordinary expenses" — childcare, medical/dental premiums, extracurricular activities, post-secondary education — are separate and split in proportion to income. This calculator does not estimate them.

Courts consider many factors beyond income and length of relationship when ordering spousal support.
Based on the Spousal Support Advisory Guidelines (SSAG) "Without Child Support" formula. Tax gross-up not applied — actual after-tax amounts will differ. These guidelines are advisory, not mandatory.
How this works — Spousal Support (SSAG) formula
SSAG "Without Child Support" Formula
Low end = 1.5% × years of marriage × income difference ÷ 12
Mid = 1.75% × years of marriage × income difference ÷ 12
High end = 2.0% × years of marriage × income difference ÷ 12
Duration
Low end: 0.5 year per year of marriage. High end: 1 year per year of marriage.
Indefinite support applies if: the marriage was 20+ years, OR the recipient's age plus years of marriage equals 65 or more.
Important Caveats
The SSAG are advisory, not mandatory. Courts consider factors such as the roles during the marriage, career sacrifices, standard of living, and each spouse's ability to become self-sufficient. These guidelines do not account for tax gross-up — actual after-tax amounts will differ.
Estimated Results
Combined support is complex.
The interaction between child and spousal support significantly affects both amounts. Legal advice is strongly recommended.
Child support based on Ontario Table (Federal Child Support Guidelines). Spousal support based on SSAG "With Child Support" formula using estimated net disposable income. Tax rates are approximated — actual amounts will vary. These guidelines are advisory only.
How this works — Both child & spousal support (SSAG with-child formula)
Step 1 — Child Support
Child support is calculated first from the Ontario Table, exactly as in the Child Support tab.
Step 2 — Net Disposable Income (NDI)
Each spouse's NDI is estimated by subtracting approximate Ontario income tax and the child support obligation from gross income. Tax rates used are approximate and do not replace actual tax calculations.
Step 3 — Spousal Support via NDI Sharing
Low = amount that brings recipient to 40% of combined NDI
Mid = amount that brings recipient to 43% of combined NDI
High = amount that brings recipient to 46% of combined NDI
Duration rules are the same as the without-child formula. The interaction between child and spousal support is complex — professional advice is strongly recommended.
