Child Disability Benefit Ontario Calculator

The Child Disability Benefit (CDB) in Ontario provides financial assistance to families with children who have a severe and prolonged disability. This calculator helps you determine your eligibility and estimate your monthly benefit amount.

How the Child Disability Benefit Works

The Child Disability Benefit is a monthly payment made to eligible families to help cover the costs of raising a child with a severe and prolonged disability. The benefit is based on the child's age and the family's income.

Important: The Child Disability Benefit is not a replacement for medical or other government benefits. It is meant to supplement family income while the child receives medical care.

Amount varies based on the child's age and the family's income

How to Calculate Your Benefit

The amount of the Child Disability Benefit is determined by the child's age and the family's income. The calculation follows these steps:

Determine the child's age category
Calculate the base benefit amount for that age category
Adjust for family income if applicable

Age Categories and Base Benefits

Age Range	Base Benefit Amount
0-5 years	$350 per month
6-11 years	$300 per month
12-17 years	$250 per month

Income Adjustment

If your family income exceeds the maximum limit, your benefit will be reduced by 5% for each $1,000 over the limit.

Benefit Adjustment Formula:

Adjusted Benefit = Base Benefit × (1 - 0.05 × (Income Over Limit / 1000))

Worked Examples

Example 1: Child aged 3 with family income below limit

Family income: $1,500 (below the $1,200 + $250 = $1,450 limit)

Base benefit: $350 (for 0-5 years)

Adjusted benefit: $350 (no reduction needed)

Example 2: Child aged 8 with family income above limit

Family income: $2,500 (above the $1,200 + $250 = $1,450 limit)

Income over limit: $2,500 - $1,450 = $1,050

Reduction: 0.05 × (1,050 / 1,000) = 5.25%

Base benefit: $300 (for 6-11 years)

Adjusted benefit: $300 × (1 - 0.0525) = $284.75
