Shared-parenting table amount comparison

If you already know each parent's official monthly table amount, compare the two figures to the cent if needed. Shared-parenting support is not determined by subtraction alone.

Arithmetic difference only

Difference between the two table amounts entered.

DirectionParent A has the higher table amount

Section 9 requires the court to take into account (a) each spouse’s applicable table amount, (b) the increased costs of shared parenting time arrangements, and (c) the conditions, means, needs and other circumstances of each spouse and child. This calculator shows only the arithmetic difference between the two entered table amounts.

This is not a shared-parenting child-support determination. It only subtracts one entered table amount from the other. Section 9 of the Federal Child Support Guidelines requires the court to consider all three statutory factors shown in the result above.

Use the official tables first

Need to find the monthly base figures? Start with the BC table lookup helper. For potentially eligible extra child-related costs, use the separate Section 7 expense calculator. Neither tool determines the final amount payable in a shared-parenting case.

Justice Canada's current child-support table look-up helps users find the base table amount based on the paying parent's gross annual income, number of children, and province or territory. It also warns that the base amount is often not the final amount, especially where there are special expenses or shared parenting. This tool is designed for the next arithmetic step once those base amounts are already known.

When the shared-parenting rule applies

Section 9 of the Federal Child Support Guidelines applies when each parent or spouse exercises not less than 40% of parenting time with a child over the course of a year. Reaching that threshold does not turn child support into a simple subtraction formula.

Why the table-amount difference is only a comparison

The difference between the two table amounts can be a useful starting comparison, but section 9 requires all three statutory factors to be considered:

the table amount that would otherwise apply to each parent or spouse;
the increased costs of shared parenting time arrangements; and
the conditions, means, needs and other circumstances of each parent or spouse and of the child.

For BC family-law cases: the BC Family Law Act Regulation adopts the Federal Child Support Guidelines as British Columbia’s child support guidelines, with specified adaptations. The federal section 9 factors therefore remain part of the BC framework.
