What is the Consumer Price Index (CPI)?
The Consumer Price Index (CPI) is a measure that examines the weighted average of prices of a basket of consumer goods and services, such as transportation, food, and medical care. It is calculated by taking price changes for each item in the predetermined basket of goods and averaging them.
In Ontario, the CPI is used to track inflation and adjust wages, benefits, and other economic indicators. A rising CPI indicates inflation, while a falling CPI suggests deflation.

Example Calculation
If you bought a loaf of bread for $3.50 in 2023 and it cost $3.00 in the base year 2012, the price index for bread would be calculated as:
(Current Price / Base Year Price) × 100 = (3.50 / 3.00) × 100 = 116.67
Formula and Assumptions
The CPI is calculated using the following formula:
CPI Formula
CPI = (Σ (Current Price × Weight) / Σ (Base Year Price × Weight)) × 100
Where:
- Current Price = Price in the current period
- Base Year Price = Price in the base year (2012=100)
- Weight = Relative importance of each item in the basket
Assumptions
- The basket of goods and services is representative of Ontario consumers
- Weights are based on Statistics Canada's methodology
- Prices are in Canadian dollars
- Base year is 2012 with index 100
Interpreting Your Results
Your personal CPI result will show how much your specific basket of goods has increased or decreased in price compared to the base year. Here's how to interpret different CPI values:
| CPI Range | Interpretation |
|---|---|
| Below 100 | Deflation - Prices have decreased |
| 100 | No change in prices |
| 101-110 | Mild inflation |
| 111-120 | Moderate inflation |
| Above 120 | Significant inflation |
Remember that a CPI above 100 means your purchasing power has decreased, while a CPI below 100 means your purchasing power has increased.
