Understanding Spousal Support

Spousal support (also called alimony or spousal maintenance) is an ongoing financial obligation that may be imposed on a higher-earning spouse to support a lower-earning spouse after separation or divorce. The Spousal Support Advisory Guidelines (SSAG) provide a framework for calculating advisory ranges.

The SSAG use different formulas depending on whether there are dependent children:

Without Dependent Children:

(1.5% to 2%) × Length of Marriage (years) × Gross Income Difference = Annual Spousal Support Range

Duration: Generally one-half to one times the length of the marriage.

With Dependent Children:

Uses the Individual Net Disposable Income (INDI) formula, which factors in the cost of child support and applies a formula based on the payor's and recipient's remaining income.

INDI Formula: (Payor INDI × 40–46%) − (Recipient INDI × 40–50%) = Monthly Spousal Support Range

Note: These are advisory guidelines only. Courts retain discretion to depart from the ranges based on factors like the standard of living during the marriage, age and health of the parties, and the ability to be self-supporting.

Frequently Asked Questions

What is the SSAG?
The Spousal Support Advisory Guidelines (SSAG) are non-binding guidelines developed by family law experts to help courts and lawyers estimate reasonable ranges for spousal support. They were developed in 2008 and are widely used across Canada, though courts are not bound by them and retain discretion to award support outside the ranges.
When is spousal support ordered?
Spousal support is not automatically awarded. Courts consider factors such as the length of the marriage, the standard of living during the marriage, the ability of each spouse to be self-supporting, and the age and health of the parties. Short marriages (less than 5 years) are less likely to result in spousal support unless there are special circumstances.
How is income determined?
For spousal support purposes, income is generally defined as gross income (before tax) and includes employment income, self-employment income, investment income, and in some cases imputed income. This calculator uses gross annual income. Courts may impute income in cases of voluntary underemployment or concealment of income.
What is the INDI formula?
The Individual Net Disposable Income (INDI) formula applies when there are dependent children. It calculates each parent's net disposable income (after taxes and child support), then applies a percentage formula (40–46% of payor's INDI minus 40–50% of recipient's INDI). This accounts for the financial impact of child support on spousal support calculations.
Can spousal support be modified?
Yes. Spousal support orders can be reviewed and modified if there has been a material change in circumstances, such as a significant change in income, remarriage, or cohabitation of the recipient. The duration and amount may be adjusted based on updated information and the guidelines.
How accurate is this calculator?
This calculator provides estimates based on the SSAG formulas and standard tax assumptions. It does not account for special circumstances, credits, deductions, or discretionary factors that a court might consider. Results should be treated as estimates only and discussed with a family lawyer for guidance specific to your situation.
