Keep in mind
  • This calculator provides estimates based on the federal Spousal Support Advisory Guidelines (SSAG). The actual amount and duration are determined by a court or agreement, considering many additional factors.
  • For the 'With Child Support' formula, accurate effective tax rates are crucial. The default rates are approximations for 2026. For precise calculations, use a current tax calculator for your specific province and income.
  • The suggested duration is expressed as a multiplier of the relationship length (e.g., 0.5 to 1). For marriages under 20 years, duration is often limited. For marriages of 20 years or more, or where the recipient's age and length of marriage exceed 65, support may be indefinite.
  • Quebec uses a different civil law system. While the SSAG are often consulted, their application may differ. Seek Quebec-specific legal advice.

What is Spousal Support in Canada?

Spousal support, also called alimony or spousal maintenance, is a payment from one spouse to the other after separation or divorce. Its purpose is to address the economic advantages and disadvantages arising from the marriage or common-law relationship. The goal is to help the lower-income spouse become self-sufficient, while also recognizing their contributions to the family and sharing the economic hardship of the separation.

How is Spousal Support Calculated?

In Canada, judges and lawyers often use the Spousal Support Advisory Guidelines (SSAG) as a starting point for calculating support. These are not strict laws but provide recommended ranges for amount and duration. The calculation depends on whether child support is also being paid.

Without Child Support Formula

This simpler formula applies when no child support is being paid for children of the relationship.

  • Step 1: Calculate the gross income difference between the payor and the recipient.
  • Step 2: Determine the applicable percentage range based on the length of the relationship. The SSAG suggest an annual entitlement of 1.5% to 2.0% of the income difference for each year of marriage or cohabitation, up to a maximum of 50% after 25 years.
    • For example, after 4 years: Low end = 4 × 1.5% = 6%. High end = 4 × 2.0% = 8%.
    • After 30 years: Both low and high ends are capped at 50%.
  • Step 3: Apply these percentages to the income difference to get the annual support range.
  • Step 4: Divide the annual range by 12 to get the monthly support range.

With Child Support Formula

This formula is used when child support is being paid. It focuses on the disposable income of each spouse after taxes and child support.

  • Step 1: Calculate each spouse's disposable income: Gross Income − (Income × Effective Tax Rate) − Annual Child Support Paid (for payor only).
  • Step 2: Find the difference between the payor's and recipient's disposable income.
  • Step 3: Take 50% of this difference as the annual base amount available for spousal support. According to the SSAG, this amount represents the range for annual support.
  • Step 4: Divide by 12 for the monthly range.

Duration of Support

The suggested duration is tied to the length of the relationship (length of marriage or cohabitation). For shorter marriages, support duration is often a fraction of the marriage length. For long-term marriages (20 years or more), or where the recipient is older and the marriage was long, support may be indefinite. Our calculator provides the standard duration range suggested by the SSAG.

Example Calculation

Consider a couple in Ontario who were married for 7 years, have no children, and are separating. The payor earns $120,000 per year, and the recipient earns $40,000.

  • Income difference: $120,000 − $40,000 = $80,000.
  • Applicable percentage after 7 years: Low = 7 × 1.5% = 10.5%. High = 7 × 2.0% = 14%.
  • Annual low range: 10.5% of $80,000 = $8,400.
  • Annual high range: 14% of $80,000 = $11,200.
  • Monthly range: $8,400 / 12 = $700 to $11,200 / 12 = $933.33 per month.
  • Suggested duration: 0.75 to 1.25 times the 7-year marriage, or 5.25 to 8.75 years.

This example illustrates the correct application of the SSAG formula, where the percentage is applied per year of marriage to the gross income difference.

Frequently Asked Questions

Are the Spousal Support Advisory Guidelines legally binding?

No. The SSAG are advisory guidelines used to bring consistency and predictability to negotiations and court decisions. A judge may order an amount outside the range based on the specific circumstances of the case.

What factors can move support outside the calculated range?

Factors include the age and health of both spouses, their needs and capacity to become self-sufficient, any property division, debts, and prior agreements. Hardship, compelling financial circumstances, or a large disparity in standards of living can also affect the amount.

Does common-law relationship qualify for spousal support?

Yes. In all Canadian provinces and territories, common-law partners may be entitled to spousal support upon separation, provided they meet the cohabitation duration requirements set by provincial law (typically 2-3 years).

Can spousal support be modified or stopped?

Yes. Spousal support orders or agreements can usually be varied if there is a significant change in circumstances, such as a job loss, substantial increase in income, retirement, or the recipient becoming self-sufficient. Support typically ends if the recipient remarries or either party dies.

How does child support affect spousal support?

Child support is paid first. The 'With Child Support' formula for spousal support then calculates the payor's disposable income after child support is deducted. This often results in a lower spousal support amount compared to the 'Without Child Support' formula.

Next Steps: Documenting Your Agreement

Once you have an estimate, you may wish to formalize the arrangement. A Separation Agreement is the primary document used to detail all terms of your separation, including spousal support, child support, and property division. Our template can help you create this comprehensive agreement. For simpler cases focusing only on support, a Spousal Support Letter can outline the payment terms. It's always recommended that each party obtain independent legal advice before signing any agreement.

Frequently asked questions

How accurate is this spousal support calculator?

This calculator applies the federal Spousal Support Advisory Guidelines (SSAG) formulas correctly. It provides a reliable estimate of the guideline range. However, the final court order or negotiated amount may differ based on many factors not captured here, such as health, property division, and specific needs.

What if we have shared custody of the children?

The SSAG formulas become more complex with shared custody. This calculator uses the standard formulas for primary residence (payor pays child support) or no child support. For shared custody scenarios, consult a lawyer for a precise calculation, as it requires adjusting incomes using set-off amounts.

Why do I need to enter tax rates for the 'With Child Support' formula?

The 'With Child Support' formula is based on disposable income after tax. Effective tax rates vary significantly by province and income level. We provide defaults, but for the most accurate estimate, you should calculate your specific combined federal/provincial effective tax rate using an online tax calculator for your province.

Is spousal support taxable?

Yes. For separations after 1997, spousal support payments are taxable income for the recipient and tax-deductible for the payor, provided the payments are made pursuant to a written agreement or court order. This tax treatment is a key reason for using disposable income in the calculations.

What happens if the payor lives in a different province than the recipient?

The court that has jurisdiction (usually where the recipient lives) will apply its own provincial laws and guidelines. This calculator uses the recipient's province for tax rate defaults in the 'With Child Support' formula. The underlying SSAG formulas are national, but provincial tax differences affect the result.

Can we agree on an amount outside the guideline range?

Absolutely. Many couples negotiate and agree on a spousal support amount that works for their specific situation, which may be higher, lower, or for a different duration than the guideline range. Such an agreement, if properly drafted in a Separation Agreement and with independent legal advice, is legally binding.
