Child Support Calculator

Use our calculator for Canadian child support estimates, including shared custody, to help you understand what your support payments may look like.



Your parenting schedule also determines how much child support is paid. "Shared" parenting applies when the parents each have a minimum of 40% of the total parenting time. If a child spends 60% or more time with one parent, put that parent in the Parenting Time Division box.

Child Support Guidelines Section 7 Expenses

Section 7 Expenses: Enter the total monthly amount for all special child-related expenses that fall in the following categories: school expenses or tutoring, daycare or childcare, dental or orthodontics, healthcare expenses including counselling, expenses for extracurricular activities including registration and equipment and costs for medical or dental insurance. Deduct any tax credits or benefits relating to these expenses first, otherwise the calculation will be inaccurate. If you are receiving spousal support this will change the proportionate sharing of section 7 expenses and the calculation for section 7 expenses below will not be accurate.

These expenses are apportioned between the parents based on their incomes.
