"Both Lauren and Gillian are knowledgeable lawyers who bring results. They communicate better then any other lawyer I’ve encountered. I am grateful to have had them assist through my divorce."

Divorce client of Lauren Zaoral and Gillian Croucher - Calgary

“I want to thank you. I hired you because you emphasized mediation, and I kept on hiring you in the face of one of my brothers and one of my friends insisting I hire a "bulldog" to counter (my ex’s) "bulldog." I'm glad I ignored their advice.”

Spouse

This calculator estimates after tax income based on gross income and provincial residence, applying common tax credits and deductions. It assumes all income is employment income, i.e. income from line 150 of your income tax return. Calculations will not be as accurate for other types of income, as different tax considerations apply.

Step 2: Spousal Support

Spousal Support Entitlement

Not everyone has a right to spousal support. If you are uncertain as to whether you are entitled to spousal support, we recommend you consult a family lawyer. If either person is entitled to spousal support, press the "yes" button below in order to enable the integrated spousal support calculator.

Is either party entitled to spousal support?

Step 3: Children

Parenting of Children

This step involves entering all children of the marriage, and identifying their primary parent. Enter dependent children using the following form by pressing the green "+" button. Then, select the parenting arrangement applicable to each child. "Shared" parenting applies only where both parents each have a minimum of 40% of total parenting time. Most children spend 60% or more time with one parent, in which case please select that parent.

Child 1:



Special Child-Related Expenses

Special child-related expenses are governed by section 7 of the Child Support Guidelines, and are apportioned between separated parents based on income after taking into consideration any child support payments. Special expenses include tuition, medical expenses, child care expenses, and other child-related costs.

Spousal and child support can increase or decrease significantly when these expenses are included.

We are no longer offering expense calculations through this calculator. It is important that tax benefits such as credits for private education, activities, or medical expenses be deducted from the total expense otherwise the calculation will be inaccurate. This requires additional information beyond the scope of this simple calculator. If you have special child-related expenses, use the Divorcepath child & spousal support calculator.

How Child Support is Calculated

Child support is calculated using the Federal Child Support Guidelines and gross parental income. In sole custody situations, support is calculated using the paying parent's income only, and this calculator looks up the child support table amount for the paying parent's guideline income. The results will be the same as Canada's official child support table look-up tool. However, in shared and split custody situations, net support is calculated based on offsetting payments that take into consideration the income of each parent. The official look up calculator does not perform these additional calculations.

For example, in shared parenting where each parent has the children at least 40% of the time (also referred to as shared custody) the calculator offsets the notional child support payable by each parent based on their respective guideline incomes.

Where each child resides primarily with a different parent (i.e. split custody) the calculator assesses child support payable by each parent and the difference is the child support payable.
