Alberta child support: what does the calculator tell you?
It gives the base monthly table amount. Parenting arrangements, special expenses, reliable income evidence, and the terms of an existing order or agreement determine what comes next.
What this calculator estimates
Enter the paying parent's annual gross income before tax, province or territory of residence, and number of children. The calculator returns the monthly Schedule I table amount from the 2025 Federal Child Support Tables, effective October 1, 2025.
The table amount is a starting point. The correct support amount depends on the law that applies, reliable income information, the parenting arrangement, and the facts of the family.
A worked Alberta example
If the paying parent lives in Alberta, earns $80,000 a year, and the table applies for one child, the 2025 table amount is $685 per month.
That example assumes a straightforward table look-up. A complete calculation may add section 7 expenses or examine shared or split parenting, undue hardship, disputed income, retroactive support, or arrears.
The income figure should be traceable to documents
For many employees, the review starts with three years of tax returns and notices of assessment, plus current pay statements. Self-employment or control of a corporation usually calls for financial statements and a closer look at business income, expenses, and personal benefits. A change in employment may require a record of employment, benefit information, or an employer letter.
For section 7 expenses, gather the invoices or receipts, proof of any subsidy or reimbursement, and the documents showing each parent's income. The net expense and the parents' respective incomes drive the proportional-sharing calculation.
Choose the process that matches the issue
The Alberta Court of Justice hears many applications about child support and parenting. The Court of King's Bench also decides child support and parenting matters and has exclusive jurisdiction over divorce and family property claims. The orders requested, the governing legislation, and the history of the file point to the appropriate court.
Alberta's free Child Support Resolution Program operates in listed communities and helps parents work toward an agreement and an enforceable consent order. Participants prepare a sworn Disclosure Statement and commonly provide three years of tax returns and notices of assessment, current pay information, business financial statements where applicable, the latest support order, and proof of special expenses. A program officer who is a family lawyer meets with the parents to calculate support and explore resolution.
Changing support and collecting support use different processes
Alberta's Maintenance Enforcement Program collects court-ordered support and enforces enrolled orders and filed maintenance agreements. The Child Support Recalculation Program, a new agreement, or a court application supplies the route for changing the amount. Until that step is completed, MEP administers the amount recorded in the enforceable document.
Keep income disclosure current even when payments flow through MEP. Updated tax information can support an annual recalculation, a negotiated amendment, or a variation application, depending on the terms of the order and eligibility for the available program.
When the calculation needs more information
The table result answers one question: the monthly Schedule I amount for the three inputs entered. A fuller support calculation brings in:
- shared parenting time or split parenting arrangements
- section 7 special or extraordinary expenses
- undue hardship claims
- income that is disputed, imputed, self-employment income, or income that varies
- income above $150,000
- retroactive support or arrears
- any order, agreement, variation, or enforcement decision
Use the estimate as a starting figure. The enforceable amount comes from the applicable order or agreement, interpreted alongside the Guidelines and the evidence for the family.
