Spousal Support Estimator (Ontario)

The SSAG are a widely-referenced framework that suggests a range for spousal support amount and duration, generally based on income difference and the length of the relationship. See Spousal Support in Ontario: A Plain-Language Guide.

No — they are informal and advisory, not legislation. No court is required to follow them, though they are widely used in practice as a starting reference point.

The two formulas behind the SSAG generally weigh the income difference between spouses and the length of the relationship (and, under one formula, the ages of any children). See Spousal Support Calculations.

No. This tool assumes entitlement and estimates a possible range only. For the separate question of entitlement, use the Spousal Support Assessment Wizard first.

Duration varies widely based on the length of the relationship and other factors — the SSAG suggest a range, but real outcomes depend on the specific facts and can be time-limited, reviewable, or indefinite.

Yes — under the SSAG, child support is generally deducted from income before the spousal support range is calculated, since child support takes priority.

Yes — support can generally be revisited if there's a material change in circumstances, such as a significant income change. See Changing Support.

No — this tool gives a pre-tax estimate only. Tax treatment can meaningfully affect the real value of a support arrangement and is worth discussing with a lawyer or accountant.

Periodic spousal support payments are generally taxable to the person receiving them and deductible for the person paying them, unlike child support, which is not. Lump-sum support is often treated differently — a lawyer or accountant can confirm how this applies to you.

Treat the range as a general starting point for discussion, not a guaranteed outcome. See Spousal Support for the fuller guides, or speak with a family lawyer.
