How BC child support is calculated

Child support in British Columbia follows the Federal Child Support Guidelines. The payor's annual gross income and the number of children determine a base monthly table amount. The recipient parent's income does not affect the table amount (except in shared or split parenting).

Table amount vs. section 7 expenses

The table amount covers everyday costs of raising the child. On top of that, section 7 special or extraordinary expenses — daycare, health premiums, orthodontics, post-secondary tuition, competitive-level extracurriculars — are shared between parents in proportion to income.

Shared and split parenting

Where each parent has the child at least 40% of the time, section 9 of the Guidelines allows a set-off: each parent's table amount is calculated, and the higher-income parent pays the difference. Courts may also depart from the set-off if the strict calculation causes hardship.

High-income payors

For payor incomes above $150,000, section 4 allows the court to depart from the tables where the strict amount would be inappropriate. This is a discretionary analysis and rarely obvious — it is one of the most common reasons to get advice before signing.

Common questions

Frequently asked.

Is this calculator accurate?
It gives a close estimate using the Federal Child Support Guidelines Simplified Tables for British Columbia. The exact amount for your file depends on the payor's Line 15000 income, section 7 special or extraordinary expenses, and any shared, split, or high-income adjustments. Treat the result as a planning number, not legal advice.
What income do I use?
Use the payor's annual gross income (Line 15000 of the T1 General). Self-employed or corporate payors may have imputed income adjustments the calculator can't apply.
What about shared parenting (40/60 or 50/50)?
Where each parent has the child at least 40% of the time, s. 9 of the Guidelines allows for a set-off rather than the full table amount. This calculator shows the full table amount; a lawyer can walk you through the shared-parenting adjustment.
What are section 7 expenses?
Section 7 covers special or extraordinary expenses on top of the table amount — daycare, medical and dental premiums, post-secondary tuition, and extracurriculars that exceed ordinary costs. They are typically shared in proportion to each parent's income.
Does high income change the calculation?
Yes. For payor incomes over $150,000 the court can depart from the tables under s. 4 of the Guidelines. The calculator's high-income output is indicative only — get advice.
