WealthInflation Calculator Canada: Future Purchasing Power
Future estimate or historical inflation?
This tool projects prices at a constant annual rate you choose. It does not retrieve historical CPI or forecast Canada’s inflation rate. A year range only sets the length of the scenario.

How inflation works
Inflation is the general, continuous rise in prices. When we say "inflation is 2%," it means that, on average, a household's basket of goods and services costs 2% more than a year earlier. Your $100 bill has not shrunk, but what it can buy has. Compounded over decades, that erosion becomes massive: at 3% per year, prices roughly double in about 24 years, and your purchasing power is cut in half over the same span.
The calculator applies the compounding of inflation, exactly like compound interest, but in reverse for purchasing power:
Future price = Amount · (1 + i)^Z and Real value = Amount / (1 + i)^Z
where Amount is the starting sum, i the annual inflation rate, and Z the number of years. The purchasing power loss in percent equals 1 − 1 / (1 + i)^Z: that is the share of your dollar's value that has evaporated. If you pick a year range, we simply use Z = end year − start year with the rate you entered (no official historical data is built in).
Worked example
Take $10,000 today and the Bank of Canada's 2% inflation target over 25 years. To buy in 2051 what $10,000 buys in 2026, you would need about $16,406: that is the "future price." Seen the other way, those same $10,000 left earning nothing would be worth only about $6,095 in today's purchasing power — a loss of roughly 39%. At 3% per year, the loss climbs to about 52% over 25 years. These are constant-rate scenarios, not forecasts.
Nominal return versus purchasing power
A positive nominal return can still lose purchasing power if prices rise faster. The exact real-return formula is (1 + nominal return) / (1 + inflation) − 1. With a hypothetical 5% nominal return and 2% inflation, that is about 2.94% before taxes and fees. Neither returns nor future inflation are known in advance. Compare another scenario in the compound interest calculator.
Frequently Asked Questions
What exactly is inflation?
Inflation is the general rise in prices across the economy over time. In practice, the same $100 bill buys a little less each year: the money itself does not change, but what it can buy shrinks. Inflation is measured by tracking the price of a representative basket of goods and services for a typical Canadian household. Inflation of 2% per year means that, on average, this basket costs 2% more than a year ago.
How does the CPI measure inflation in Canada?
Statistics Canada publishes the Consumer Price Index (CPI) every month, tracking the cost of a fixed basket of roughly 700 goods and services: housing, groceries, transport, clothing, health care, recreation, and more. The 12-month change in the CPI is the most quoted annual inflation rate. The Bank of Canada aims to keep inflation around 2%, the midpoint of a 1% to 3% target range. This calculator uses a constant annual rate that you choose: that is a simplification, since real-world inflation varies from year to year.
Does investing always beat inflation?
Investing does not guarantee a return above inflation. Real return adjusts nominal growth for changes in purchasing power: (1 + nominal return) / (1 + inflation) − 1. Compare assumptions, fees, taxes and the risk of losses; the calculator is an illustration, not a forecast or investment recommendation.
What inflation rate should I use for a long projection?
Use several assumptions to see how sensitive the result is. For example, 2%, 3% and 4% are illustrative constant-rate scenarios, not a forecast, historical average or guaranteed range. The default 2% refers to the Bank of Canada’s target, not the latest measured inflation rate.
