Step 2: Enter Parent 2's Income

Input the gross annual income of the second parent. This is also the total income before any deductions.

Step 3: Select Number of Children

Choose the number of children for whom child support is being calculated. The calculator supports calculations for 1 to 6 children.

Step 4: Calculate

Click the "Calculate" button to compute the child support amount. The calculator will display the weekly and monthly support amounts.

Formula Used

The Ontario Child Support Guidelines use a formula to determine the appropriate child support amount. The basic formula is:

Child Support Formula

Child Support = (Parent 1's Income + Parent 2's Income) × Child Support Rate × Number of Children

The Child Support Rate is determined based on the combined income of both parents and the number of children.

Worked Example

Let's look at a worked example to illustrate how the child support calculator works.

Example Scenario

Parent 1's Income: $60,000 per year
Parent 2's Income: $50,000 per year
Number of Children: 2

Calculation Steps

Combine the incomes: $60,000 + $50,000 = $110,000
Determine the child support rate for $110,000 income: 18.5%
Calculate the total child support: $110,000 × 18.5% = $20,350
Divide by the number of children: $20,350 ÷ 2 = $10,175 per child

Results

Weekly Child Support: $195.62
Monthly Child Support: $825.00

This example shows how the calculator computes the child support amount based on the provided incomes and number of children.
