https://www.canada.ca/en/revenue-agency/services/child-family-benefits/canada-child-benefit-overview/canada-child-benefit-we-calculate-your-ccb.htmlBasic benefit for July 2016 to June 2018
We calculate the Canada child benefit (CCB) as follows:
$6,400 per year ($533.33 per month) for each eligible child under the age of six
$5,400 per year ($450.00 per month) for each eligible child aged 6 to 17
We start to reduce the amount of CCB you get when your adjusted family net income (AFNI) is over $30,000. The reduction is calculated as follows:
families with one eligible child: the reduction is 7% of the amount of AFNI between $30,000 and $65,000, plus 3.2% of the amount of AFNI over $65,000
families with two eligible children: the reduction is 13.5% of the amount of AFNI between $30,000 and $65,000, plus 5.7% of the amount of AFNI over $65,000
families with three eligible children: the reduction is 19% of the amount of AFNI between $30,000 and $65,000, plus 8% of the amount of AFNI over $65,000
families with four or more eligible children: the reduction is 23% of the amount of AFNI between $30,000 and $65,000, plus 9.5% of the amount of AFNI over $65,000
