Should you start CPP at 60, 65 or 70?
Starting CPP at 60 cuts your pension by 36% for life. Waiting until 70 raises it by 42%. Those two numbers are fixed and published, so the whole decision comes down to how long you live and what the money is worth to you in the meantime. On undiscounted arithmetic the totals cross at roughly 74 for 60 against 65, and roughly 82 for 65 against 70. This calculator starts from the average new pension of $877.01 a month rather than the maximum, because most Canadians never reach the maximum.
Quebec residents: this tool does not apply to you. If you worked in Quebec you contributed to the Quebec Pension Plan, not the Canada Pension Plan. The QPP is a separate plan with its own early and late take up adjustment and its own enhancement parameters, and those rules were deliberately out of scope for the research behind this page. No QPP figures appear anywhere on this page, and nothing here should be read as a QPP estimate. Use Retraite Quebec for QPP numbers.
The CPP timing calculator
Your results
These crossovers are arithmetic, not prediction. At a zero real discount rate they land near 74, 82 and 78. Change the discount rate and they move, sometimes by years. They assume both streams are indexed identically, that your age 65 entitlement is the same whichever age you start, and that tax and the OAS recovery tax do not intrude. None of that is perfectly true. This is longevity insurance, not a bet you win.
The month by month adjustment table
The adjustment is published and mechanical. Payments decrease by 0.6% each month, which is 7.2% a year, up to a maximum reduction of 36% at age 60. Payments increase by 0.7% each month, which is 8.4% a year, up to 42% at age 70 (canada.ca, Date modified 2026-06-18). Note the asymmetry: 0.6% down, 0.7% up. These are the post 2016 fully phased in factors. The adjustment is linear in months rather than stepped by year, so a start at 63 years and 7 months is 17 months early, which is minus 10.2%, not minus 14.4%.
| Start age | Months from 65 | Adjustment | Factor | On the average $877.01 | On the maximum $1,507.65 |
|---|---|---|---|---|---|
| 60 | -60 | -36.0% | 0.640 | $561.29 | $964.90 |
| 61 | -48 | -28.8% | 0.712 | $624.43 | $1,073.45 |
| 62 | -36 | -21.6% | 0.784 | $687.58 | $1,182.00 |
| 63 | -24 | -14.4% | 0.856 | $750.72 | $1,290.55 |
| 64 | -12 | -7.2% | 0.928 | $813.87 | $1,399.10 |

How the CPP adjustment actually works
The standard age to start the Canada Pension Plan retirement pension is 65. The earliest you can start is 60 and the latest is 70, with no further increase for waiting past 70 (canada.ca, 2026-06-18). Inside that window, Service Canada applies a fixed actuarial adjustment to whatever your age 65 entitlement happens to be. The adjustment is permanent. It is not a temporary reduction that catches up later, and there is no mechanism to change your mind and reset the factor once payments begin.
Because the two rates differ, the window is not symmetric around 65. Five years early costs 36% of the pension; five years late gains 42% of it. Measured against the age 60 amount instead, waiting the full ten years more than doubles the cheque: the factor moves from 0.640 to 1.420, a 122% increase. Same arithmetic, harder framing.
The factors do not capture what happens to the underlying entitlement. Taking CPP before 65 ends your contributory period earlier, so the earnings average and the 17% general dropout are calculated over a shorter window, and low or zero earning years between your start age and 65 no longer drag the average down. Deferring past 65 adds no dropout benefit. The consequence is that any purely factor based calculator, this one included, will misestimate for someone with an incomplete record.
Why the average matters more than the maximum
This is where most CPP calculators go wrong, and the error is large enough to invalidate everything downstream. The maximum CPP retirement pension at 65 is $1,507.65 a month for new benefits commencing January 2026. The average retirement pension at 65 was $877.01 a month as of April 2026 (canada.ca, Date modified 2026-07-02). The average is about 58% of the maximum. Default a tool to the maximum and you hand the typical Canadian a figure roughly $7,568 a year too high.
The reason so few reach the maximum is structural. It requires contributing at or above the Year's Maximum Pensionable Earnings for roughly 39 of the 47 years between 18 and 65. Career breaks, caregiving years, part time work, self employment with low declared income, arriving in Canada mid career, and simply earning under the ceiling all reduce it. Most working lives contain at least one of those. Canada.ca says it plainly: the maximum and average amounts are not guaranteed, and your actual pension may differ depending on your contribution history and when you start collecting.
The fix is to stop guessing. Sign in to your My Service Canada Account and open your Statement of Contributions, which is built from your actual record. One caveat even there: it assumes you keep earning at your recent rate until your start age. If you plan to retire at 58 and start CPP at 65, it will overstate you, because it has quietly assumed seven more years of contributions you are not going to make.
The crossover method and its assumptions
The method is simple enough to check by hand. Let B be your age 65 monthly entitlement. Cumulative nominal payments from a start age to some later age are B multiplied by the factor for that start age, multiplied by 12, multiplied by the number of years you have been collecting. Set two options equal and solve for the age at which they match. Using the published factors and no discounting at all, the 60 against 65 comparison crosses at roughly 74, the 65 against 70 comparison at roughly 82, and the 60 against 70 comparison at roughly 78.
Those three figures are the floor of the plausible range, not the answer. Four things move them. First, the discount rate: money received at 60 can stay invested or spare your portfolio a withdrawal, and any positive real rate pushes the crossover later, favouring early take up. That is the largest swing factor and it is a user assumption, not a fact, which is why the input sits above rather than baked in. Second, indexation: CPP is indexed to the Consumer Price Index each January, and because the deferred benefit is larger in absolute terms the same percentage compounds on a bigger base, pulling the crossover earlier. This tool works in today's dollars and assumes indexation tracks inflation, so the rate you enter is a real rate and the two effects net rather than double count. Third, contributory period effects, described above. Fourth, tax and the OAS recovery tax, which can shift the after tax crossover by years for a household near the threshold.
A fifth consideration has nothing to do with arithmetic. The maximum combined survivor and retirement pension in 2026 is 1,756.14 dollars a month, so a deferred CPP is not fully inheritable by a surviving spouse. For some couples that weakens the case for deferral whatever the crossover says.
So this page will not tell you the breakeven age is 81 and 11 months. It gives the method, shows the undiscounted result, and lets the number move when you change the assumptions driving it. Any tool quoting a single breakeven age as fact has hidden its assumptions rather than resolved them.
Longevity is the real frame, not the bet
Breakeven framing quietly turns a pension decision into a wager on your own death date, which is both morbid and analytically backwards. Deferring CPP is better understood as buying longevity insurance: cheap, government backed, indexed to inflation, and paid for with the years of pension you forgo between your actual start age and 70.
Insurance is not something you expect to win. You buy fire insurance hoping never to claim. The risk deferral covers is outliving your money, and a Canadian reaching 65 has a median remaining life expectancy into the mid eighties, which sits above the 65 against 70 undiscounted crossover. But a median describes a population and you are one person. Health history, family longevity and occupation dominate. Someone with a serious diagnosis at 61 and someone with four grandparents who reached 95 are not facing the same decision.
The useful question is not which choice has the higher expected value. It is which failure you would rather live with.
The useful question is not which choice has the higher expected value. It is which failure you would rather live with. Deferring and dying at 72 means your estate received less than it might have, at a point when you are past caring. Starting at 60 and living to 96 means 31 years of a permanently reduced indexed income stream that is your only real longevity hedge. Those regrets are not symmetric.
What deferring costs you in the gap years
Here is where this stops being a pension question and becomes a portfolio question, which is the part index investors tend to underweight. Deferring CPP does not make the gap years free. If you retire at 60 and start CPP at 70, you have ten years of spending to fund from somewhere else, and for a DIY investor that somewhere else is usually the portfolio. Deferral is effectively financed by a larger withdrawal rate in your sixties in exchange for a larger indexed cheque afterwards.
That trade has a name in portfolio terms: it front loads your sequence of returns risk. The years you withdraw most are the years immediately after you stop working, which is exactly when a bad early market outcome does the most structural damage. Selling units into a drawdown early in retirement permanently reduces the capital base that has to carry you for another three decades, and the bigger cheque at 70 does not undo a portfolio harvested badly at 62.
There is a genuine offset. Once the larger CPP starts, your portfolio withdrawal rate falls for life, and the income it replaces is indexed and guaranteed in a way no equity portfolio is. Deferral shifts a slice of your retirement income from market dependent to government backed. That is a real reduction in sequence risk, just realised later.
The honest approach is to model the whole drawdown rather than the pension decision alone. Our retirement calculator handles the portfolio side, and the XEQT withdrawal strategy guide covers how to sequence withdrawals from a single fund portfolio without doing structural damage in the first decade. CPP timing is an input to that plan, not a substitute for it.
One planning move sits directly at the intersection: the low income years between 60 and 70, before CPP and OAS start, are the cheapest years you will ever have to draw down an RRSP or RRIF at a low marginal rate, which shrinks the mandatory RRIF minimums that would otherwise stack on a deferred CPP after 71. Whether it nets out positive depends on your numbers.
Working while collecting, and the post retirement benefit
You can collect CPP and keep working, and the rules differ by age. Between 60 and 65, contributions are mandatory. From 65 they become optional, and you opt out using Form CPT30, with a copy to each employer and the original to CRA, or Schedule 8 if you are self employed. Only one change is permitted per calendar year. At 70 contributions stop regardless (canada.ca, 2025-01-22).
Each year you contribute while collecting generates a separate post retirement benefit, payable from January of the following year and stacked permanently on your pension. Multiple years produce multiple stacked benefits. They are indexed, lifelong and fully taxable.
This page does not publish derived post retirement benefit amounts, and the reason is worth stating. Canada.ca describes the maximum as 2.5%, or one fortieth, of the maximum retirement pension, but its own published figures do not reconcile with that rule once the age adjustment is applied. Rather than invent a number that looks precise and is not, the honest treatment is the mechanism: contribute while collecting, earn a small additional indexed benefit for each qualifying year, receive it from January of the following year, and expect it to be modest next to the pension itself. For your own figure use the published canada.ca amounts or your Service Canada statement, not a formula.
CPP enhancement, YMPE and YAMPE
The CPP is midway through a phased enhancement, and it changes what the maximum means over time. Two ceilings now matter. The YMPE, or Year's Maximum Pensionable Earnings, is the original ceiling: base CPP plus the first additional component are contributed on earnings between the 3,500 dollar basic exemption and the YMPE. The YAMPE, or Year's Additional Maximum Pensionable Earnings, is a second ceiling introduced in 2024 and phased in over 2024 and 2025. It does not replace the YMPE, it creates a second band above it.
| Parameter | 2026 figure |
|---|---|
| YMPE | $74,600 |
| YAMPE | $85,000 |
| Employee rate below the YMPE | 5.95% |
| Maximum employee contribution | 4,230.45 dollars |
| Rate on the band between the ceilings | 4.0% each for employee and employer |
For 2026 the YMPE is $74,600 and the YAMPE is $85,000. The employee rate below the YMPE is 5.95%, giving a maximum employee contribution of 4,230.45 dollars, and the rate on the band between the ceilings is 4.0% each for employee and employer, with the self employed paying both halves. These are 2026 figures. The 2027 YMPE and YAMPE have not been announced as of 2026-09-23, and CRA normally announces them in November. Nothing here projects them.
On the benefit side, CPP historically replaced one quarter, 25%, of average work earnings. Under the enhancement it grows to replace one third, 33.33%, of covered average earnings received after 2019, and the maximum level of earnings protected rose by 14% over 2024 and 2025. Canada.ca states the enhancement will increase the maximum retirement pension by more than 50% for those who make enhanced contributions for 40 years.
Read that last sentence carefully, because it is routinely misquoted at near retirees. The enhancement only credits contributions from 2019 onward. Someone retiring in 2026 has at most seven enhanced years and captures a small fraction of the eventual uplift. The more than 50% figure belongs to workers with a full 40 enhanced years, meaning people retiring in the 2060s. If you are choosing between 60 and 70 today, the enhancement mostly explains why the published maximum keeps ratcheting upward faster than plain inflation.
CPP is not clawed back, but it does raise your clawback income
CPP is not subject to any income tested recovery. The social benefits repayment at line 23500 applies only to the OAS pension at line 11300, net federal supplements at line 14600, and Employment Insurance benefits at line 11900. The CPP retirement pension at line 11400 appears nowhere in that list (canada.ca, Date modified 2026-01-20). No means test, no asset test, no income ceiling.
That is where most explanations stop. The complication is that CPP is fully taxable and sits at line 11400, which flows into line 23400, and line 23400 is the exact figure that determines the OAS recovery tax. Every extra dollar of CPP adds a dollar to your OAS clawback base. For someone between the minimum and maximum OAS recovery thresholds, the marginal cost of an extra CPP dollar is their marginal income tax rate plus the 15% recovery rate. At a 30% marginal rate that is an effective 45%.
Deferring makes this worse in the post 70 years, not by any quirk but by simple stacking: a CPP 42% larger arrives on top of RRIF minimums that ramp after 71. Someone who defers both CPP and OAS to 70 and ignores the interaction in their sixties can walk into the recovery zone in their seventies. For reference, the minimum income recovery threshold for the 2025 income year is 93,454 dollars, driving the recovery period from July 2026 to June 2027 (canada.ca, Date modified 2026-06-29). None of that argues against deferral. It argues for looking at the whole retirement income picture before treating the CPP start age as a standalone decision.
What this calculator does not do
Short version: it applies published adjustment factors to a number you supply. Everything below is outside its scope, and pretending otherwise would make it less useful rather than more.
- It does not cover the QPP. Quebec workers contribute to the Quebec Pension Plan, which has different early and late take up adjustments and different enhancement parameters. Those rules were out of scope and no QPP figure appears on this page.
- It does not model survivor benefits. The maximum combined survivor and retirement pension in 2026 is 1,756.14 dollars a month, and that cap means a deferred pension is not fully inheritable by a spouse.
- It does not model disability benefits or the conversion of a disability pension to a retirement pension.
- It cannot see your contribution history. Your entitlement depends on 47 years of earnings, dropout provisions and enhanced contribution years no public calculator can access. The adjustment factors are exact; the number you multiply them by is the guess.
- It does not calculate tax and does not output an OAS recovery tax figure. It flags the interaction in prose and leaves the arithmetic to your return.
- It does not publish post retirement benefit amounts, for the reconciliation reason set out above.
- It does not project unannounced figures. The 2027 YMPE, YAMPE and maximum pension amounts are not announced as of 2026-09-23 and are not extrapolated.

Frequently asked questions
Taking CPP at 60 locks in a permanent reduction of 36%, because the pension falls 0.6% for each of the 60 months you start early (canada.ca, 2026-06-18). On undiscounted arithmetic the cumulative totals cross at roughly age 74. If you are in good health and have portfolio or employment income to live on meanwhile, waiting wins on total dollars. If your health is poor, or you need the cash, starting at 60 can be the better call. There is no universal answer, because the crossover moves with the discount rate you assume and with how long you actually live.
On undiscounted arithmetic using the published factors, the 65 versus 70 crossover falls at roughly age 82 and the 60 versus 70 crossover at roughly age 78. Those figures assume a zero real discount rate and identical indexation on both streams. Any positive real discount rate moves the crossover later, which favours starting earlier. Treat it as an output of your assumptions, not as a published fact.
The maximum at 65 for new benefits commencing January 2026 is 1,507.65 dollars a month, but the average recipient who started at 65 was receiving 877.01 dollars a month as of April 2026, about 58% of the maximum (canada.ca, 2026-07-02). The maximum requires contributing at or above the YMPE for roughly 39 of the 47 years between 18 and 65. Only your My Service Canada Account Statement of Contributions can tell you your own figure.
No. The social benefits repayment at line 23500 applies to the OAS pension, net federal supplements and Employment Insurance benefits. The CPP retirement pension at line 11400 is not in that list, so there is no means test and no income ceiling on CPP (canada.ca, 2026-01-20). CPP is fully taxable though, and it flows into line 23400, the figure that determines the OAS recovery tax. CPP is never clawed back itself, but every extra dollar of it raises the income that claws back your OAS.
Yes. Between 60 and 65 contributions are mandatory. From 65 to 70 they are optional and you opt out using Form CPT30, with one change permitted per calendar year. At 70 contributions stop regardless (canada.ca, 2025-01-22). Each qualifying year generates a separate post retirement benefit, payable from January of the following year and stacked on your pension for life.
No. Quebec workers contribute to the Quebec Pension Plan, not the Canada Pension Plan. The QPP has its own actuarial adjustment for early and late take up and its own enhancement parameters, and those rules were out of scope here. If you worked in Quebec, use Retraite Quebec figures instead.
