How to Use the Canadian Child Support Calculator
Select Province: Choose the payer's province. Income tax rates vary slightly by province, which affects the Federal Tables. Note: Quebec has its own distinct system.
Enter Gross Income: Input the annual gross income (Line 15000 of your tax return) for both parents. While Sole Custody only requires the Payer's income, Shared Custody and Special Expenses (Section 7) require both.
Check Shared Parenting: Tick the box if each parent has custody for at least 40% of the time. This switches the calculation to the "Set-Off" method (Parent A Table Amount minus Parent B Table Amount).
Add Section 7 Expenses: Enter the total monthly cost of special expenses (e.g., daycare, orthodontics). The calculator will split this amount between parents based on their income proportion.
Frequently Asked Questions
What counts as Section 7 (Special) Expenses?▼
Section 7 expenses are costs that are not covered by the basic Table amount. These include childcare expenses, medical/dental insurance premiums, health-related expenses exceeding $100/year, and extraordinary expenses for extracurricular activities or post-secondary education.
What is the 40% Rule for Shared Custody?▼
Under Section 9 of the Federal Guidelines, if a parent has physical custody of a child for at least 40% of the time over the course of a year, they are considered to have "Shared Custody." In this case, the support amount is typically calculated by offsetting the Table amounts of both parents.
Should I use Gross or Net Income?▼
The Federal Child Support Tables are based on **Annual Gross Income** (before taxes). However, when splitting Section 7 expenses, the courts may look at Net Income (after taxes) to determine the fair proportion for each parent. This calculator uses Gross Income ratios for simplicity.
Does this calculator work for Quebec?▼
No. Quebec has its own provincial guidelines and a different calculation model that considers the assets and income of both parents regardless of custody time. Please use the official Quebec resources listed below.
