Inflation Calculator Ontario

Reviewed by Calculator Editorial Team

Adjust past prices to today's Ontario values using this inflation calculator. Enter an original price and the year it was paid to see how much it would cost today, accounting for Ontario's Consumer Price Index (CPI) changes.

How to Use This Calculator

To calculate Ontario inflation adjustments:

  1. Enter the original price in the "Original Price" field
  2. Select the year the price was paid from the dropdown
  3. Click "Calculate" to see the adjusted price

The calculator uses Ontario's CPI data to determine the appropriate adjustment factor. The result shows what the original price would be worth today, accounting for inflation.

Note: This calculator uses average Ontario CPI data. For more precise adjustments, you may need to use more specific CPI data for particular categories of goods and services.

Formula Used

The inflation-adjusted price is calculated using the following formula:

Adjusted Price = Original Price × (CPIcurrent / CPIoriginal)

Where:

  • CPIcurrent = Current year's Ontario CPI
  • CPIoriginal = Original year's Ontario CPI

The calculator uses the most recent Ontario CPI data available. For years before 1914, the base year is 1914 with a base index of 100.

Worked Example

Let's say you paid $100 for a product in 2010. What would that be worth today (2023) in Ontario?

  1. Original Price = $100
  2. Year Paid = 2010
  3. CPI for 2010 = 104.9 (base year 1914 = 100)
  4. CPI for 2023 = 126.7
  5. Adjusted Price = $100 × (126.7 / 104.9) ≈ $120.80

So, $100 in 2010 would be worth approximately $120.80 today in Ontario, accounting for inflation.
