CPP & OAS to increase in January

With this morning's release of the Consumer Price Index (CPI) for the month of October 2025 we can now calculate the next increase for both CPP & OAS which will begin with the monthly payments in January.

The annual CPP adjustment is based on the average monthly CPI for the twelve months ending with October this year over the same average twelve month period ending last year.  The math looks like this;

163.6 ➗ 160.4 ➖ 1 🟰 2%

This 2% is slightly lower than the current annual inflation rate of 2.2% as it's a twelve month average as opposed to a one month over month snapshot.

The quarterly OAS adjustment is calculated similarly except it's a quarter over quarter rather than a year over year calculation.  It'll be based on the three months ending with October over the three months ending in July.  The OAS calculations are;

165.0 ➗ 164.5 ➖ 1 🟰 .3%

This .3% seems like a pittance but when combined with earlier 2026 quarterly adjustments the January 2026 payment will represent a 2% increase over the January 2025 payment.
