How this calculator works
Enter your adjusted family net income and the number of children in each age band. The maximum benefit is $8,157 a year for each child under 6 and $6,883 for each child aged 6 to 17. Those figures, the $38,237 and $82,847 income thresholds and the reduction rates below are the ones that apply to payments from July 2026 to June 2027, which are based on 2025 income. Up to the first threshold the full amount is paid. Between the thresholds the benefit falls by 7% a child for one child, 13.5% for two, 19% for three and 23% for four or more. Above the second threshold the reduction continues at 3.2%, 5.7%, 8% or 9.5% on top of the amount already reduced. The result is never below zero. This page does not model the child disability benefit, shared custody, the child who is not in your care, the Alberta and Quebec family benefits, or the July changeover to the following year's amounts.
Formula
Base = children under 6 x $8,157 + children 6 to 17 x $6,883. Below $38,237 of adjusted family net income the benefit is the base. Between $38,237 and $82,847, reduction = first rate x (income - $38,237). Above $82,847, reduction = fixed amount + second rate x (income - $82,847). Benefit = max(0, base - reduction).
Worked example
One child under 6 with an adjusted family net income of $30,000 receives the full $8,157. At $50,000 the reduction is 7% of $11,763, or $823.41, so the benefit is $7,333.59. At $100,000 the reduction is $3,123 plus 3.2% of $17,153, or $3,671.90, leaving $4,485.10. Two children aged 6 to 17 at $100,000 receive $13,766 less $6,999.72, which is $6,766.28.
Frequently asked questions
Which year's income is used?
Payments from July 2026 to June 2027 are based on your 2025 adjusted family net income. The Canada Revenue Agency recalculates each July.
What is adjusted family net income?
Your net income plus your spouse's or common-law partner's net income, minus certain deductions such as a registered disability savings plan contribution.
Is the benefit taxable?
No. The Canada Child Benefit is not taxable and does not reduce any other benefit.
What if we share custody?
With shared custody each parent receives half of the benefit they would otherwise get. This calculator assumes one household receives the full amount.
