Spousal support range estimator
Estimate the basic SSAG without-child-support range from gross incomes and relationship length. It does not calculate cases that require the with-child-support formula.
What this calculator can—and cannot—do
The official SSAG without-child-support formula uses 1.5%–2% of the gross income difference for each year of cohabitation, with caps, and a duration range of 0.5–1 year per year of relationship. This simplified estimator uses Justice Canada’s rough 48% upper-range safeguard for long relationships rather than calculating the actual net-income equalization cap; specialized software may show a different upper amount. The rule of 65 and relationships of 20+ years can make duration indefinite (duration not specified).
Use the result as a discussion range for legal advice, mediation or settlement planning—not as a prediction of a court order.
Important income limits: Under the Spousal Support Advisory Guidelines, the basic formula is generally not applied on its own when the higher-income spouse earns under $20,000 or over $350,000 per year. Between $20,000 and $30,000, ability to pay can call for adjustments. The $350,000 ceiling is not a hard cap on support. Exceptional circumstances, entitlement and individual facts still matter.
