How the Inflation Calculator Works
The calculation is: Adjusted Amount = Original Amount × (CPI in target year ÷ CPI in base year). The Consumer Price Index (CPI) measures the average change in prices paid by consumers for a basket of goods and services over time. When CPI rises, the same amount of money buys less — that is inflation.
- Canada — data from Statistics Canada, Table 18-10-0005-01. Annual average CPI, all-items, base year 2002=100.
- United States — data from the U.S. Bureau of Labor Statistics, CPI-U annual averages, base period 1982-84=100.
- Annual rate — computed as the compound annual growth rate (CAGR) of CPI between the two years: (CPI_to/CPI_from)^(1/years) − 1.
Data Sources and Accuracy
Every CPI value in this tool is hardcoded from official government sources — no interpolation, no estimation. For Canada, the data comes from Statistics Canada Table 18-10-0005-01 (Consumer Price Index, annual averages, all-items, not seasonally adjusted, 2002=100). Coverage starts at 1950.
For the United States, the data comes from the Bureau of Labor Statistics historical CPI-U table (all urban consumers, 1982-84=100). This series starts in 1913, making it one of the longest continuous inflation records available.
The CPI measures average price changes for a representative basket of goods — food, housing, transportation, medical care, and more. It is a useful approximation but not a perfect measure of any individual's experience: if you spend most of your budget on healthcare (whose prices rise faster), your personal inflation rate is higher than CPI suggests.
Real data, two countries, CAGR included
Most inflation calculators online use rough estimates or don't cite their source. This one hardcodes every year individually from the official StatCan and BLS tables, with source citations visible in the result. The compound annual growth rate is shown alongside the total inflation percentage, so you can see both the cumulative effect and the average yearly rate.
What isn't here: real-estate specific inflation, wage-adjusted comparisons, or projections beyond 2024. The tool is deliberately backward-looking — it computes what already happened, using data that has already been published. No forecasting.
