What Is Inflation?

Reach your savings goals faster with one of the highest interest rates

Inflation is the rate at which the average prices of goods and services rise over time. When inflation increases, the same amount of money buys less than it did before.

For example, if something costs $100 and its price rises by 3%, it would cost $103.

How Does Inflation Work?

Inflation measures how quickly prices are changing across the economy rather than looking at the price of one individual product.

If coffee becomes more expensive, that alone does not necessarily mean inflation is high.

Inflation refers to a broader and persistent increase in the average price of goods and services.

How Is Inflation Measured in Canada?

Canada primarily measures inflation using the Consumer Price Index, or CPI.

Statistics Canada tracks the cost of a representative basket of goods and services purchased by Canadians. It compares how the cost of that basket changes over time.

The basket includes categories such as:

  • Food

  • Shelter

  • Transportation

  • Clothing

  • Household expenses

  • Health and personal care

  • Recreation and education

The most commonly discussed inflation rate compares the CPI with the same month one year earlier.

What Causes Inflation?

Inflation can happen for several reasons.

Demand increases

If consumers want more goods and services than businesses can supply, businesses may raise prices.

Costs increase

Businesses may face higher costs for:

  • Labour

  • Fuel

  • Materials

  • Transportation

  • Rent

Some of those costs may be passed on to consumers through higher prices.

Supply becomes limited

Supply disruptions can make certain goods harder to find.

When supply falls but demand remains strong, prices can rise.

At its most basic level, inflation is influenced by the relationship between supply and demand.

How Does Inflation Affect Your Money?

Inflation reduces purchasing power.

Suppose you have $1,000.

If prices rise by 3% while your income and savings remain unchanged, that $1,000 will not buy as much as it did before.

Inflation can affect:

  • Groceries

  • Rent

  • Mortgage costs

  • Transportation

  • Utilities

  • Travel

  • Everyday purchases

How Does Inflation Affect Savings?

Inflation matters because the return on your savings determines whether your money is keeping pace with rising prices.

If your savings earn 1% while inflation is 3%, your account balance may still increase, but your purchasing power is declining.

For longer-term savings, it can be useful to compare the return you are earning with the inflation rate.

What Is Canada's Inflation Target?

The Bank of Canada aims to keep inflation at 2%, the midpoint of a target range between 1% and 3%.

The goal is not to eliminate inflation entirely.

Low and predictable inflation can make it easier for households and businesses to plan spending, saving and investment decisions.

If you're wondering whether rising prices are always harmful, see is inflation good or bad?.

What Is the Difference Between Inflation and the Cost of Living?

Inflation measures how average prices are changing across the economy.

Your personal cost of living depends on what you actually spend money on.

For example, someone who spends a large portion of their income on rent may experience rising costs differently from someone who owns their home outright.

This means your personal expenses can increase faster or slower than the official inflation rate.

Does Inflation Mean Prices Will Eventually Go Back Down?

Not necessarily.

When inflation falls, it usually means prices are increasing more slowly.

For example, inflation dropping from 6% to 2% does not mean prices fall back to where they were before. It means the overall price level is still increasing, just at a slower rate.

A widespread decline in prices is called deflation.

Why Does Inflation Matter?

Inflation affects the real value of your income and savings.

When prices rise faster than your wages or savings returns, your purchasing power decreases.

Understanding inflation can help you make better decisions about budgeting, saving, borrowing and investing because it shows how the value of money changes over time.
