Child Support Calculator

Use this child support calculator to calculate child support payable according to the 2025 Canadian Federal Child Support Guidelines and the Child Support Tables specific to each province.

This calculator has been updated to include the new table amounts coming into effect on October 1, 2025. Use it to calculate current support obligations. For retroactive support claims, please contact us or try the Divorcepath calculator.

You

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 15000 of your income tax return. Calculations will not be as accurate for other types of income, as different tax considerations apply.

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?

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.

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.
