CPP & the adjustment · Indexation

How CPP's annual cost-of-living adjustment is calculated

The role of the Consumer Price Index and why the 2026 figure came out at 2.0%.

The 2.0% figure for 2026 did not come from a policy decision made each year. It is the output of a fixed formula tied to the cost of living. Understanding that formula explains why the number is what it is.

The Consumer Price Index

CPP benefits are indexed using the Consumer Price Index (CPI), Statistics Canada’s measure of the average change over time in the prices of a basket of consumer goods and services. Once a year, the Government of Canada uses the CPI to adjust CPP benefits that are already being paid.

The adjustment takes effect every January. Its purpose is to help CPP income keep pace with changes in the cost of living, so that a pension does not lose value in real terms as prices rise.

How the 2026 rate was calculated

The rate compares two 12-month averages of the CPI. For 2026, the average over November 2024 to October 2025 is set against the average over November 2023 to October 2024.

PeriodAverage CPI
November 2024 – October 2025163.6
November 2023 – October 2024160.4
Resulting adjustment2.0%

Dividing 163.6 by 160.4 gives an increase of about 2.0%. That is the figure applied to CPP benefits in payment for January through December 2026.

What the formula does and does not do

Because it is a formula, the annual rate is not negotiable and is the same percentage for the benefits it applies to. It does not, however, mean every recipient sees the same dollar increase: the percentage is applied to each person’s existing benefit, so the dollar change depends on the amount already being paid.

The indexation also protects against decreases. Under the Canada Pension Plan rules, the adjustment does not reduce benefits; if the cost of living were to fall, payments would stay the same rather than go down.
