Sharing child expenses by income
Incomes
The yearly income each parent's share is worked on. Which income counts is for the guideline or agreement that governs the file.
Expenses
Yearly amounts. Take off any subsidy, benefit, tax credit or deduction that relates to the expense, and anything the child pays toward it.
Each parent's share
Parent 1 60.0% · Parent 2 40.0% of the combined income
| Expense | To share | Parent 1 | Parent 2 |
|---|---|---|---|
| Child care | $10,000.00 | $6,000.00 | $4,000.00 |
| Orthodontics | $3,000.00 | $1,800.00 | $1,200.00 |
| A year | $13,000.00 | $7,800.00 | $5,200.00 |
| A month | $1,083.33 | $650.00 | $433.33 |
Arithmetic only. It does not decide which expenses are shared, what counts as income, or whether an expense is reasonable. Monthly figures are the yearly ones divided by twelve.
What it works out
For each expense: the yearly cost, less any subsidy, benefit, tax credit or deduction relating to it, less what the child pays. What is left is split in the ratio of the two incomes, to the cent, and the two shares always add back to the amount shared.
In Canada this is the principle section 7(2) of the Federal Child Support Guidelines sets for special or extraordinary expenses: the expense “is shared by the spouses in proportion to their respective incomes after deducting from the expense, the contribution, if any, from the child.” Section 7(3) requires subsidies, benefits and tax deductions or credits relating to the expense to be taken into account. Elsewhere, the guideline or agreement that governs the file decides which expenses are shared and on which income.
Nothing is looked up, and nothing you type is saved or sent anywhere.
