We modelled CPP break-even after tax in three provinces. It barely moved.

The standard advice is that CPP breaks even at "about 74" — meaning if you live past 74, waiting until 65 beats taking it at 60. We modelled it properly: after federal and provincial tax, with the OAS clawback included, across Ontario, Alberta and British Columbia. Two results surprised us. The province barely matters. And 74 is the answer to a question most people aren't asking.

Where 74 comes from — and what it leaves out

CPP can start any month between 60 and 70. Starting early costs 0.6% per month (−36% at 60). Delaying adds 0.7% per month (+42% at 70). On the average new pension of $925.35/month at 65, that's:

The "74" figure compares 60 against 65. Take it at 60 and you bank five years of cheques before the 65-starter gets anything; they then catch up at about $3,998 a year. Divide, and the crossover lands just shy of 74.

But almost nobody's actual decision is 60-versus-65. It's usually 60 versus 70 (take it as soon as possible, or wait as long as possible), or 65 versus 70 (retire and claim, or bridge the gap and wait). Those are different questions with materially different answers.

The results, after tax

Break-even age, modelled after federal and provincial tax with the OAS clawback applied, for a retiree with the average CPP:

Finding 1: the province is nearly irrelevant

We expected provincial tax to shift the answer. It doesn't — across three provinces with genuinely different rate structures (Alberta's flat-ish 8% first bracket, BC's 5.6%, Ontario's 5.05% plus surtaxes), break-even moves by at most one year, and usually not at all.

The reason is arithmetic, and once you see it you can't unsee it: break-even only shifts if your marginal tax rate differs between the two scenarios. If the CPP dollars you'd receive at 60 and the CPP dollars you'd receive at 70 land in the same tax bracket, tax scales both streams identically and cancels out of the comparison entirely. It's the same reason the RRSP-versus-TFSA decision collapses to a single question about your rate now versus later.

So the honest headline is: if a financial advisor is adjusting your CPP timing for your province, they're solving the wrong problem.

Finding 2: the real numbers are 78 and 81, not 74

This is the finding that actually matters. If your decision is 60 versus 70 — which, for anyone who can afford to wait, it usually is — you need to live to 78, not 74, for delaying to pay off. If you're choosing between claiming at 65 and waiting to 70, you need to reach 81.

A Canadian who reaches 65 today has a life expectancy well into their mid-80s, and roughly half will exceed it. So delaying still wins on average — but the margin is thinner than "74" implies, and it arrives later in life, which is precisely when the money is least useful to most people and most useful to a few. That asymmetry is the actual decision.

Finding 3: the one thing that does move the answer

Look at the $95,000 row. Break-even slips a year, in every province. That's the OAS clawback doing exactly what it does: a larger CPP at 70, stacked on other income near the $95,323 threshold, means some of those extra dollars are taxed at your marginal rate plus a 15% OAS recovery. The effective rate on delayed CPP goes up, so it takes longer to catch up.

This is the real interaction to model — not your province, but whether delaying CPP pushes you across the clawback line. For a retiree with a large RRIF and a big CPP, delaying to 70 can mean the incremental pension is taxed at an effective rate north of 45%. That doesn't necessarily make delay wrong. It does mean the break-even you were quoted is optimistic.

What actually should drive the decision

Break-even analysis quietly assumes the thing you're optimizing is total dollars collected before you die. For most people, that's the wrong objective. Consider instead:

• Longevity insurance. CPP at 70 is inflation-indexed income you cannot outlive. Its real value isn't the expected total — it's protection against the scenario where you live to 95 and the portfolio didn't. You buy it precisely because you might lose the bet.
• Your health, honestly assessed. If you have a condition that meaningfully shortens your life expectancy, take it early. The break-even table is a group average and your situation isn't average.
• Whether you need the money now. Someone who must choose between CPP at 60 and drawing down an RRSP at 60 is not choosing between two cheques; they're choosing which asset to spend first. That's a withdrawal-order question, and it usually dominates.
• Your spouse. CPP survivor benefits are capped, and the interaction with a couple's combined income is where the genuinely large numbers live.

Method

Break-even is the first age at which cumulative after-tax income from the later start exceeds the earlier start. Modelled on 2026 constants: average new CPP at 65 of $925.35/month, adjusted −0.6%/month before 65 and +0.7%/month after; full OAS from 65; 2026 federal and provincial brackets for ON/AB/BC; OAS recovery tax at 15% above $95,323. Amounts are in today's dollars — CPP and OAS are inflation-indexed, so this is equivalent to assuming benefits and brackets rise together. We do not assume CPP proceeds are invested; if you invest an early CPP at a meaningful real return, break-even moves later, and if you'd otherwise be liquidating investments to fund the gap, it moves earlier.

Not financial advice. A model tells you which question matters, not what your answer is.
