Money basics
What Is Inflation?
A simple guide to understanding why prices change and what inflation means for your money.
Start here
Inflation in 30 seconds
Inflation is a general increase in prices over time. When prices rise, each dollar may buy less than it did before.
Today
$100
buys a certain basket
Later
$100
may buy less
Hypothetical simplified example
What happens to purchasing power?
Imagine a basket of everyday purchases costs $100 today. If prices rose at a constant hypothetical 2% each year, the approximate cost of the same basket would change like this:
Today
$100
1 year later
$102
5 years later
about $110
10 years later
about $122
Canada’s main measure
How is inflation measured?
Statistics Canada uses the Consumer Price Index—CPI—as Canada’s primary measure of consumer inflation. CPI compares how the cost of a representative fixed basket of goods and services changes over time.
Items are weighted using household spending patterns, so categories on which consumers spend more have more influence on the overall index. Review the Statistics Canada CPI explanation.
A broad average
Inflation doesn’t mean everything rises by the same amount
If headline CPI inflation is 3%, that does not mean every price increased by exactly 3%. Some categories can rise faster, rise more slowly, remain relatively stable, or fall.

Spending patterns matter
Your inflation may feel different
CPI describes average price change across a representative national basket—not the exact experience of every person. Households spend their money differently, so changes in particular prices can affect them differently.
Household A
- High rent
- No vehicle
- Lower transportation spending
Household B
- Mortgage
- Two vehicles
- Childcare expenses
Statistics Canada’s Personal Inflation Calculator illustrates how unique spending weights can produce an experience different from official CPI. Its result is informational and is not an official statistic.
Several forces can interact
Why does inflation happen?
Demand
When demand for goods and services grows faster than available supply, prices may face upward pressure.
Supply
Shortages, production disruptions, or supply-chain problems can reduce availability and raise prices.
Costs
Higher labour, material, energy, transportation, or other input costs can contribute to higher prices.
Real-world inflation can result from several interacting causes rather than one single event.
Low, stable, and predictable
Is inflation always bad?
Very high or unpredictable inflation can reduce purchasing power and make planning more difficult. Canada’s monetary-policy framework does not, however, target permanent zero inflation.
Target range · 2% midpoint · over the medium term
The Bank of Canada currently aims to keep total CPI inflation at the 2% midpoint of a 1%–3% target range over the medium term. This does not mean 2% inflation is always “good”; the objective is inflation that is low, stable, and predictable. See the Bank of Canada inflation-control target.
The balance is not the whole picture
How inflation can affect savings
Bank balance today
$20,000
Five years later
$20,000
Even though the dollar balance is unchanged, its purchasing power may decline if prices rose. Interest earned on savings may offset some of that decline, depending on the interest rate, inflation, and taxes where applicable.
Nominal vs. real
Growth isn’t the whole story
A financial balance can grow in nominal dollars while inflation reduces what those dollars can buy. Imagine hypothetical investment growth of 6% while hypothetical inflation is 2%. The dollar balance may have increased by 6%, but the improvement in purchasing power is smaller after considering inflation.
Nominal growth
What the dollar balance did.
Real growth
Growth after considering inflation and purchasing power.
This is conceptual: simply subtracting inflation from return is not an exact calculation in every context.
Understanding Compound GrowthPlanning over time
Why inflation matters for long-term goals
Retirement
An amount that supports a lifestyle today may not buy the same lifestyle decades from now.
Home ownership
Housing-related costs can change substantially over time.
Education
Future education costs may differ from today’s costs.
Long-term goals should be considered in terms of future purchasing power—not only today’s dollar amounts.
Borrowing is nuanced
How inflation can interact with debt
Debt can be affected differently depending on whether its interest rate is fixed or variable, how market rates and income change, and the type of borrowing. A fixed payment may remain nominally unchanged while other prices and income change. Variable borrowing costs may change when interest rates move.
That complexity is why it is too simplistic to say inflation is automatically good for borrowers.
Monetary policy
What does the Bank of Canada do?
The Bank of Canada uses monetary policy—including changes to its policy interest rate—to influence economic conditions and help keep inflation near its target over time.
Inflation pressure too high
Policy rates may rise
Borrowing tends to become more expensive
Demand may cool
Inflation pressure too low
Policy rates may fall
Borrowing tends to become less expensive
Demand may strengthen
Simplified illustration. Monetary policy works through the economy over time and does not mechanically control every individual price or guarantee an immediate result. See the Bank of Canada monetary-policy overview.
