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: annual PRB = Service Canada's published maximum new PRB at age 65 for the following year × (your pensionable earnings ÷ that year's YAMPE, capped at 1) × age adjustment factor. Service Canada publishes this maximum directly each year (it reflects the CPP enhancement's higher accrual rate plus the CPP2/YAMPE second-additional tier, so it runs higher than a simple 1/40 share of the retirement pension — the January 2026 maximum new PRB is $54.69/month, versus a maximum retirement pension of $1,507.65/month). Earnings between the YMPE and YAMPE count toward your PRB too, since CPP2 contributions on that band build enhanced benefit just like CPP1 does below the YMPE.
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.

Frequently asked questions
What is the CPP Post-Retirement Benefit (PRB)?
The PRB is a separate lifetime monthly benefit you build up by continuing to work — and continuing to make CPP contributions — after you have started taking your CPP retirement pension. Each year of contribution earns a small additional payment that begins the next year and is paid for life on top of your regular CPP retirement pension.
Are CPP contributions mandatory after I start CPP?
Between 60 and 64 they are mandatory if you are working as an employee — you and your employer must both contribute. From 65 to 69 they are optional: you can elect to stop by filing form CPT30 with your employer (and a copy with the CRA). From the year you turn 70, no further CPP contributions are allowed.
How much PRB do I earn each year?
Service Canada publishes the maximum new PRB at age 65 directly each year — it is not a simple 1/40 share of the maximum retirement pension, because it reflects the CPP enhancement's higher accrual rate plus the CPP2/YAMPE second-additional tier. Your annual PRB is that published maximum × (your pensionable earnings ÷ that year's YAMPE, capped at 1) × an age adjustment factor. At age 65 with maximum earnings, the published maximum new PRB is $54.69/month for life, starting the following year.
Should I file CPT30 to stop contributing at 65?
It depends on the breakeven calculation: contributions are paid up-front in cash, while PRB pays out across the rest of your life. If you expect to live well past your contribution years, continuing to contribute usually pays off; if you have health concerns or want the cash now, the CPT30 election may be the right call. The calculator shows your personal breakeven age side-by-side.
Is the PRB indexed to inflation?
Yes. Once a PRB starts paying, it is indexed annually to the Consumer Price Index — the same indexation as the CPP retirement pension. This calculator shows the year-of-earning value; in real-life dollars the lifetime value will be higher because of the CPI uplift.
Is the PRB taxable?
Yes — the PRB is taxable income reported on your T4A(P) like the rest of your CPP. Conversely, the CPP contributions you make to earn it qualify for the federal CPP enhancement deduction (the post-2019 enhanced portion) and a non-refundable tax credit (the original 4.95% portion), partially offsetting the up-front cost.
