CPP Post-Retirement Benefit Calculator
Working past 60 while collecting CPP? You're earning a separate lifetime benefit on top of your existing pension — the Post-Retirement Benefit (PRB). Estimate how much PRB you'll build, what it costs you in CPP contributions, and whether the CPT30 election to stop contributing at 65 is worth it for your situation.

How the Post-Retirement Benefit works
The PRB is the CPP system's reward for continuing to contribute after you've started your retirement pension. It was added as part of the 2012 CPP changes and works alongside the regular pension — you don't have to choose between the two. Each year you contribute earns a small additional payment that begins the following year and continues for life.
The formula (Service Canada): annual PRB = 1/40 × maximum CPP retirement pension at 65 in the following year × (your pensionable earnings ÷ YMPE) × age adjustment factor.
The age adjustment factor mirrors the CPP retirement pension start-age rules: 0.6% reduction per month before 65 (so age 60 = 64%), and 0.7% increase per month after 65 (so age 70 = 142%). Practically: earning PRB at 67 is worth about 17% more per year than earning it at 65.
Mandatory vs optional contributions: between 60 and 64, contributions are mandatory if you're employed; from 65 to 69 you can file CRA form CPT30 to stop contributing (and earning more PRB); from the year you turn 70, contributions are no longer allowed under any election.
Indexation: once a PRB starts paying, it's CPI-indexed for life — so the headline numbers in this calculator understate the real-dollar value over a long retirement.
