Calculate child support in AlbertaHow child support works in Alberta
Child support in Alberta is calculated using the Federal Child Support Guidelines. These guidelines provide a consistent framework based on the paying parent's income and the number of children.
The base amount comes from the Alberta table, which reflects Alberta's provincial tax rates. Because after-tax income differs by province, table amounts vary even at the same gross income. The amount depends on the paying parent's annual income and the number of children.
The base amount may be adjusted for shared parenting (where each parent has the child at least 40% of the time), split custody (where each parent has primary care of at least one child), or special expenses under section 7 of the Guidelines. For incomes above $150,000, the tables provide a base-plus-percentage formula, and the court may also consider the specific needs of the children.
Key facts
Alberta Table
Base amounts from the Alberta-specific table under the Federal Child Support Guidelines, adjusted for provincial tax rates.
Shared Custody
When each parent has the child at least 40% of the time, the set-off formula under section 9 uses both parents' table amounts.
Special Expenses
Section 7 expenses — including child care, health care, education, and extracurricular activities — are shared proportionally to each parent's income.
Income Range
Tables provide amounts up to $150,000, plus a percentage formula for higher incomes. The court may also consider the children's specific needs.
