Alberta child & spousal support calculator.
Enter your details, save scenarios for later, and see exactly how the numbers are derived — step by step, using the Alberta column of the Federal Child Support Tables and the SSAG.
Child's age
Section 7 — special expenses (annual)
- Payor's income ($0) is below the $16,000 table threshold — no table amount is payable (Schedule I).
- Payor table amount (DOJ 2025 Alberta — 1 child, payor income $0): $0/mo.
- Section 3(1) — primary parenting: payor pays the full Alberta DOJ table amount of $0/mo.
Used for the rule of 65.
- SSAG Without Child Support Formula — amount: 1.5%–2% of the gross income difference ($0) per year of cohabitation (0 yr), to a maximum of 50%.
- Range from formula: 0.0%–0.0% × $0 = $0–$0/yr.
- Net-income equalization cap not engaged — formula upper end ($0/yr) is below the equalization amount (≈ $0/yr).
- Duration: 0–0 years (½ to 1 year per year of cohabitation). Marriage < 20 yrs and rule of 65 does not apply (recipient age 0 + 0 yrs = 0).
How child and spousal support work in Alberta
In Alberta, child support is governed by the Federal Child Support Guidelines (for divorcing parents) and the parallel Alberta Child Support Guidelines (for unmarried parents). The amount is driven primarily by the payor's Guideline Income and the number of children, with extra "section 7" contributions for special and extraordinary expenses such as child care, health premiums, post-secondary tuition, and significant extracurricular costs.
Spousal support is more discretionary. The Spousal Support Advisory Guidelines (SSAG) produce a low–mid–high range based on the length of the relationship, both incomes, ages, and whether children are involved. Courts treat SSAG as a strong starting point, but the right number for your file depends on entitlement, the basis of the claim (compensatory, non-compensatory, or contractual), and your overall financial picture.
What this calculator does — and what it doesn't
This tool gives you a fast, plain-language estimate so you can plan a budget, prepare for a four-way meeting, or sanity-check an offer. It uses the current Guideline tables and SSAG formulas, but it does not replace legal advice. Real files involve income that has to be properly determined (self-employment add-backs, imputed income, RRSP withdrawals, bonuses), shared- and split-parenting adjustments under section 9, undue-hardship claims, and tax considerations on lump-sum or retroactive support.
Treat the numbers here as a starting point for a conversation, not a court order.
Getting your inputs right
- Guideline income usually starts with line 15000 of your most recent T1, with adjustments under Schedule III of the Guidelines.
- Parenting time matters: the shared- parenting threshold is at least 40% of the time with each parent over the year.
- Number of children includes all children of the relationship for whom support is payable.
- Section 7 expenses are shared in proportion to incomes after applying any child tax benefits.
Common questions
Is the calculator's number legally binding?
No. Only an agreement signed by both parties or an order of the court is binding. The calculator is an estimate based on the inputs you provide.
My ex is self-employed — can I still rely on this?
Self-employment income often needs to be re-cast for support purposes (personal-use expenses, retained earnings in a corporation, dividend gross-ups). Run the calculator on the headline number, then have a lawyer pressure-test the income.
Does spousal support always apply?
No. Entitlement is a threshold issue. Many short, dual-income relationships without children produce no spousal support obligation even when the SSAG formula returns a range.
Can I save and revisit my calculation?
