If you are going through a separation or divorce in British Columbia, one of the biggest questions you will face is: how much spousal support will I pay or receive?
This page gives you a clear, plain-language overview of how spousal support is calculated in BC. It is a starting point, not legal advice. Every situation is different, and getting the right outcome requires proper legal guidance.
More information on parenting arrangements after separation is available through BC’s Parenting After Separation resources.

In BC, spousal support is calculated using the Spousal Support Advisory Guidelines (SSAG) — a federal framework designed to make support amounts more consistent and predictable.
The SSAG produces a range, not a fixed number. There is a low end, a mid-range, and a high end. Where you land within that range depends on the specific facts of your case.
There are two formulas:
Example: 10-year marriage, $50,000 income gap → $7,500 to $10,000 per year.
Duration: roughly 0.5 to 1 year per year of marriage.
After 20 years of marriage or when the Rule of 65 applies, support may be indefinite.
Used when child support is also being paid. This formula uses Individual Net Disposable Income (INDI), targeting 40–46% of the combined net income for the lower-income spouse after child support is factored in.
This formula is more complex and depends heavily on custody arrangements, tax credits, and each parent’s income.
Factor | How It Affects Support |
Length of marriage or relationship | Longer relationships generally mean higher and longer support |
Income difference between spouses | Larger gap = larger support amount |
Roles during the relationship | Stay-at-home parent or career sacrifices increase entitlement |
Dependent children | Affects which formula is used and the amount |
Standard of living | Courts consider the lifestyle maintained during the relationship |
Ability to become self-supporting | Shorter support if the recipient can re-enter the workforce quickly |
In BC, indefinite spousal support may apply when the years of marriage plus the recipient’s age at separation equals 65 or more — even in shorter marriages.
Example: 12-year marriage + 53 years old at separation = 65 → indefinite support may apply.
Scenario | Estimated Duration | Notes |
Married under 5 years, both employed | 1–3 years | Transitional support only |
10-year marriage, one spouse stayed home | 5–10 years | Compensatory support for career sacrifice |
20+ year marriage, primary caregiver | Indefinite | Long-term financial dependency recognized |
Common-law couple, 3 years together | 1–2 years | Subject to entitlement analysis |
These are general estimates only. Your actual entitlement depends on your specific circumstances.
Yes. Spousal support is not fixed forever. It can be varied if:
One spouse’s income increases or decreases significantly.
The recipient remarries or enters a new relationship.
The recipient becomes self-supporting.
Children’s needs change.
The BC Family Law Act governs parenting arrangements in BC and sets out what courts consider when evaluating the best interests of the child.
Yes. Under the BC Family Law Act, a common-law partner who lived with their spouse for at least two years — or who has a child together — may be entitled to spousal support after separation. The same SSAG formulas apply.

It depends on the length of the relationship, financial dependency, and the recipient’s ability to become self-supporting.
