This tool estimates the base monthly amount from the 2025 Federal Child Support Tables (in force 1 October 2025) for Ontario, British Columbia, and Alberta, using the paying parent's income, number of children, and province. It does not include section 7 special or extraordinary expenses, and the amount can differ with shared or split custody, income over $150,000, undue hardship, or a child of the age of majority. It is general information, not legal or financial advice, and RecordingLaw.com is not a government body. Confirm your figure with the official Department of Justice look-up tool, and consult a family lawyer about your situation.
How the Table Amount Is Set
The base amount of child support in Canada comes from the Federal Child Support Tables, which were updated effective 1 October 2025. The amount depends on just three things: the paying parent's gross annual income, the number of children, and the paying parent's province or territory of residence (each province has its own table reflecting provincial tax rates). This calculator uses the 2025 tables for Ontario, British Columbia, and Alberta, the three highest-demand provinces, and reproduces the Department of Justice figures exactly at every point tested.
Below a low-income floor of $16,000, the table amount is $0. Above that, the amount rises with income, and for income over $150,000 the tables apply a set amount on the first $150,000 plus a percentage of the rest. For a full explanation, see how the federal tables work.
What the Table Amount Leaves Out
The table figure is the starting point, not the whole story. On top of it, parents usually share section 7 special or extraordinary expenses (such as child care, health costs over $100 a year, and post-secondary education) in proportion to their incomes. The table amount can also change where the child spends at least 40% of the time with each parent, under the shared custody rules.
Two important limits: Quebec uses its own model (based on both parents' incomes) when both parents live there, so this calculator does not apply, and for provinces and territories other than Ontario, BC, and Alberta, use the official Department of Justice look-up tool. This tool estimates the base amount only; a court makes the binding order.
Frequently Asked Questions
Is this the exact amount of child support I will pay or receive?
It is the base table amount for the income, number of children, and province you enter, taken from the 2025 Federal Child Support Tables. It is not the whole obligation: section 7 special expenses are usually added on top, and shared custody, income over $150,000, or undue hardship can change it. A court or a signed agreement sets the binding figure.
Which income is used, the payer’s or both parents’?
For the federal tables, only the paying parent’s gross annual income is used for the base table amount. Both parents’ incomes matter for section 7 expenses (shared in proportion) and in shared-custody cases. Quebec’s own model uses both parents’ incomes for the base amount.
Why does the province matter if the child lives somewhere else?
The federal table amount is based on the paying parent’s province of residence, not the child’s, because each provincial table reflects that province’s tax rates. If the paying parent moves provinces, the applicable table can change.
Does this use the current 2025 tables?
Yes. The Federal Child Support Tables were updated effective 1 October 2025 (SOR/2025-166), the first revision since 2017. This calculator uses the 2025 figures. The older 2017 tables still apply to retroactive periods before 1 October 2025.
Does this tool store or send my information?
No. All of the math runs in your browser. Nothing you enter is saved, transmitted, or used to contact you.
