Child Support Calculator (Canada)

The Federal Child Support Tables are schedules to the Federal Child Support Guidelines (SOR/97-175) that set the base monthly amount a paying parent owes, based on their province or territory of residence, their annual income, and the number of children. Every province and territory except Quebec has adopted these federal tables in their own provincial child support laws, so the same amounts apply whether a case proceeds under the federal Divorce Act or provincial family law.

The tables were updated effective October 1, 2025 (SOR/2025-166) -- the first update since 2017. The new amounts were generated using the same federal child support formula, updated with more recent (2023) tax rules. The income floor at which an obligation begins also moved -- for example, from $12,000 to $16,000 in Ontario.

Each table is built from $1,000 income bands. For an income inside a band, the amount is the band's basic amount plus a percentage applied to the portion of income above the band's floor. For example, the Guidelines themselves give this worked example: British Columbia, 2 children, $51,250 income, basic amount $807, percentage 1.54%, band floor $51,000 -- $807 + [1.54% x ($51,250 - $51,000)] = $810.85 per month.

Guidelines section 4 applies. By default (s.4(a)), the table amount at $150,000 continues to apply, extended by the same percentage the table uses at its top band, for the income above $150,000. A court can instead order a different amount for the excess (s.4(b)), based on the children's condition, means, needs and other circumstances, and each parent's financial ability to contribute.

Only when the federal Guidelines govern -- typically a divorce case where the other parent lives outside Quebec. Quebec has its own child support determination model, which applies whenever both parents reside in Quebec: a different, income-shares-style formula based on both parents' disposable income, not just the paying parent's income. Use the Quebec government's own Child Support Payments Calculation Tool for a Quebec-Quebec case -- this site does not implement the Quebec model.

No. The table amount is the base amount only. Section 7 of the Guidelines allows additional "special or extraordinary expenses" to be shared proportionally to income -- childcare, certain medical and dental expenses, health-related insurance premiums, extraordinary extracurricular expenses, and post-secondary education costs, among others. Shared-custody arrangements (each parent has the children at least 40% of the time) and undue-hardship claims can also adjust the final amount. This calculator does not model section 7 add-ons, shared-custody set-off, or undue hardship.

The federal formula behind each table accounts for provincial income tax rates, so a support payer in a lower-tax province has more after-tax income at a given gross income and a correspondingly different table amount. That is why Schedule I publishes a separate table for each province and territory.
