Ontario Health Premium Calculation 2025

The Ontario Health Premium is a mandatory payment for residents of Ontario who receive publicly funded healthcare services. This calculator helps you estimate your 2025 premium based on your income and family size.

How the Ontario Health Premium is Calculated

The Ontario Health Premium is determined based on your household income and the number of people in your family. The calculation follows these steps:

Determine your household income for the previous year
Calculate the income threshold based on your family size
If your income exceeds the threshold, calculate the premium amount
Apply any applicable credits or deductions

Ontario Health Premium = (Household Income - Income Threshold) × Premium Rate

The premium rate for 2025 is 2.5% of the amount by which your income exceeds the threshold.

Factors Affecting Your Premium

Several factors influence the amount of your Ontario Health Premium:

Household income: Higher incomes result in higher premiums
Family size: Larger families have higher income thresholds
Provincial tax credits: Some residents may qualify for reductions
Residency status: Only Ontario residents are eligible

Note: The Ontario Health Premium is separate from the Ontario Health Insurance Plan (OHIP) premium, which is based on your personal income.

Example Calculation

Let's calculate the premium for a family of four with a household income of $120,000 for 2024.

Income threshold for a family of four: $80,000
Excess income: $120,000 - $80,000 = $40,000
Premium amount: $40,000 × 2.5% = $1,000

This family would pay a 2025 Ontario Health Premium of $1,000.

Next Steps

Once you've calculated your premium, you should:

Check your income tax return to confirm your household income
Review your family size for accurate threshold calculation
Apply for any provincial tax credits you may qualify for
Pay your premium by the deadline (typically April 30)
