The Federal Child Support Guidelines, and Provincial Guidelines in Quebec, set out the rules for calculating the amount one parent must pay to the other parent to help support their child or children. The guidelines are used by judges throughout the country to establish the amount of child support due.
Keep in mind, the amount displayed on the calculator is for information purposes only. If you believe the amount in your order or agreement should be changed based on the Guidelines, you will need to apply to the court for a Variation Order.
To calculate your basic child support amounts enter the Income, Number of children and the Province, then click the Calculate button:

The Canadian Federal Child Support Guidelines apply to all divorces and separation agreements which came into being after May 1, 1997. The effect of the guidelines was to remove the calculation of child support from the discretion of judges and make the payment of child support more predictable.
Under the Federal Child Support Guidelines, the basic amount of child support is determined by considering:
- the number of children;
- the province or territory where the paying parent lives;
- and the paying parent's gross annual income.
(a) to establish a fair standard of support for children that ensures that they continue to benefit from the financial means of both spouses after separation;
(b) to reduce conflict and tension between spouses by making the calculation of child support orders more objective;
(c) to improve the efficiency of the legal process by giving courts and spouses guidance in setting the levels of child support orders and encouraging settlement; and
(d) to ensure consistent treatment of spouses and children who are in similar circumstances.
