Child Support Guidelines Calculator Ontario

This calculator helps you determine child support payments in Ontario based on the official guidelines. It takes into account both parents' incomes, expenses, and custody arrangements to provide an accurate estimate.

How to Use This Calculator

To calculate child support payments in Ontario:

Enter the gross monthly income for both parents
Select the number of children for whom support is being calculated
Choose the custody arrangement (shared or sole custody)
Click "Calculate" to see the recommended child support amount

The calculator uses the Ontario Child Support Guidelines to determine the appropriate payment amount. These guidelines are based on a percentage of the combined income of both parents, adjusted for the number of children and custody arrangements.

Formula Used

Child Support Calculation Formula

The Ontario Child Support Guidelines use the following formula to calculate child support:

Child Support = (Combined Income × Percentage) ÷ Number of Children

Where:

Combined Income = Parent 1 Income + Parent 2 Income
Percentage is determined by the Ontario Child Support Guidelines based on income brackets
Number of Children is the total number of children for whom support is being calculated

The exact percentage applied depends on the combined income of both parents. The guidelines provide specific percentage ranges for different income brackets to ensure fair and consistent child support payments.

Worked Example

Let's look at an example to see how the calculator works:

Example Calculation

Parent 1 Income: $3,500/month

Parent 2 Income: $2,800/month

Number of Children: 2

Custody Arrangement: Shared

Combined Income: $3,500 + $2,800 = $6,300/month

Percentage Applied: 18% (based on Ontario guidelines for this income bracket)

Calculation: ($6,300 × 0.18) ÷ 2 = $567/month per child

Total Monthly Support: $567 × 2 = $1,134/month

In this example, the calculator would recommend $567 per month for each child, totaling $1,134 per month for two children. The exact amount may vary slightly depending on the specific income brackets and rounding rules in the Ontario Child Support Guidelines.
