Deciding when to start your Canada Pension Plan (CPP) benefit is one of the most consequential retirement income choices Canadians face. Taking CPP at 60 locks in a permanently lower monthly amount. Waiting until 70 locks in a permanently higher amount. The breakeven analysis determines the age at which the strategy of waiting catches up to the strategy of starting early, in terms of cumulative lifetime benefit received. This calculator charts all three start ages — 60, 65, and 70 — against your expected plan-to age and identifies which approach produces the highest total benefit.
What is the best age to start CPP?
At a plan-to age of 85, starting CPP at 70 almost always produces the highest cumulative lifetime benefit. The breakeven between starting at 60 and starting at 65 is approximately age 74. The breakeven between starting at 65 and starting at 70 is approximately age 82. A Canadian who reaches 85 and started at 70 has received significantly more in total CPP benefits than if they had started at 60 or 65. The advantage of starting early at 60 is realized only for those with a plan-to age below approximately 74.
How CPP start-age adjustments work
Taking CPP before 65
CPP can be started as early as age 60. Each month before 65 that benefits begin, the monthly amount is reduced by 0.6%. Taking CPP at exactly 60 (60 months early) reduces the benefit by 36%: 60 months × 0.6% = 36.0%. A benefit of $1,100 per month at 65 becomes $704 per month at 60. This reduced amount is permanent and does not increase back to the standard amount once the recipient reaches 65.
Deferring CPP beyond 65
Each month after 65 that CPP is deferred, the monthly amount increases by 0.7%. Deferring to exactly 70 (60 months late) increases the benefit by 42%: 60 months × 0.7% = 42.0%. A benefit of $1,100 per month at 65 becomes $1,562 per month at 70. This enhanced amount is also permanent and is indexed to the Consumer Price Index annually, preserving purchasing power throughout retirement.
The cumulative benefit calculation
Total CPP received at any age equals the annual benefit at the chosen start age multiplied by the number of years since starting. The breakeven age between two start strategies is the age at which the total received by the later starter catches up to the total received by the earlier starter. Before the breakeven, the earlier starter leads in total received. After the breakeven, the later starter leads permanently.

Worked example: planning to age 90, $1,100 CPP at 65
A recipient with an estimated CPP of $1,100 per month at 65 plans to age 90 (25 years after turning 65). Monthly benefits at each start age: 60 = $704, 65 = $1,100, 70 = $1,562. Annual benefits: 60 = $8,448, 65 = $13,200, 70 = $18,744.
Cumulative at plan-to age 90: starting at 60, benefits received from age 60 to 90 = 30 years × $8,448 = $253,440. Starting at 65, benefits from 65 to 90 = 25 years × $13,200 = $330,000. Starting at 70, benefits from 70 to 90 = 20 years × $18,744 = $374,880. At age 90, starting at 70 produces $44,880 more than starting at 65 and $121,440 more than starting at 60.
The breakeven between starting at 60 and 65 occurs when cumulative benefits cross: $8,448 × (age – 60) = $13,200 × (age – 65). Solving: age = ($8,448 × 60 – $13,200 × 65) / ($8,448 – $13,200) = ($506,880 – $858,000) / (-$4,752) = 73.9. The break-even is approximately age 73.9. The breakeven between starting at 65 and 70 similarly works out to approximately 81.9.
Rules and edge cases
Health and longevity uncertainty
The actuarially neutral design of the CPP adjustment factors means that, on average, a Canadian who lives to median life expectancy receives approximately the same lifetime total regardless of start age. The 2026 median life expectancy for a Canadian reaching 65 is approximately 87 years for men and 89 years for women (Statistics Canada). Starting at 70 is the better choice for those who expect to live longer than the median. Starting at 60 is the better choice for those with significantly below-median life expectancy due to health conditions. The calculator shows exactly where the crossover lies for any plan-to age.
Spouse coordination
CPP decisions for couples are interdependent. The pension-sharing rules under the CPP allow spouses to split their CPP entitlement for income tax purposes without changing the underlying benefit structure. A higher-earning spouse deferring to 70 while the lower earner takes CPP at 65 can be an effective income-splitting and tax-reduction strategy, particularly if deferring the high earner’s CPP to 70 means the OAS survivor benefit falls partly on a lower-income survivor in future.
Post-retirement benefit (PRB)
A CPP recipient who continues working and contributing after starting CPP benefits automatically accrues a Post-Retirement Benefit (PRB) for each year of continued contributions. The PRB is a separate, smaller monthly benefit added on top of the base CPP pension. Recipients aged 65 to 70 may choose to stop contributing to CPP, but those under 65 must continue contributing if employed. Each year of PRB accrual adds roughly 1/40th of the maximum CPP increment for that contribution year.
CPP survivor benefit interaction
When a CPP recipient dies, a surviving spouse or common-law partner may be entitled to a CPP survivor’s pension. The combined survivor plus own-CPP pension is capped at the maximum monthly CPP benefit. A recipient who has deferred to 70 and receives a higher benefit may leave a reduced net increase to the survivor if the survivor’s own CPP plus the survivor’s pension exceeds the cap. This interaction should be modelled with a financial adviser when both partners have substantial CPP entitlements.
OAS interaction: the 70-year-old’s advantage
Old Age Security (OAS) can also be deferred from 65 to 70, with a 0.6% monthly increase for each month of deferral. Deferring both CPP and OAS to 70 maximizes inflation-indexed guaranteed income for life. For Canadians who have other income to draw on between 65 and 70 (TFSA, RRIF withdrawals, employment), deferring both federal pensions to 70 is the highest-floor strategy. The combined maximum CPP plus OAS at 70 in 2026 is approximately $3,500 per month, fully indexed.
CPP enhancement and post-2019 contributions
The CPP Enhancement, phased in from 2019, increases the income replacement rate from 25% to 33.33% of earnings up to the Year’s Maximum Pensionable Earnings (YMPE). Workers who contributed after 2019 will receive enhanced CPP benefits on top of the base CPP. The start-age adjustment factors (0.6% and 0.7% per month) apply equally to both the base CPP and the enhanced CPP component. The Statement of Contributions from Service Canada reflects all contributions, both base and enhanced.
Frequently asked questions
- What is the best age to start CPP?
- The best age depends on how long you expect to live. The breakeven between starting at 60 and starting at 65 is approximately age 74. The breakeven between starting at 65 and starting at 70 is approximately age 82. A Canadian who lives to 85 or beyond receives significantly more in total CPP by waiting until 70. Those with health conditions suggesting below-median longevity may benefit from starting at 60 or 65.
- How much is CPP reduced if taken at 60?
- CPP taken at 60 is reduced by 0.6% for each month before age 65, totalling a 36% reduction (60 months × 0.6%). A benefit of $1,000 per month at 65 becomes $640 per month at 60. The reduction is permanent and does not reverse when the recipient reaches 65. Benefits are still indexed to CPI annually, but from the lower base amount.
- How much is CPP increased if deferred to 70?
- CPP deferred to 70 increases by 0.7% for each month after age 65, totalling a 42% increase (60 months × 0.7%). A benefit of $1,000 per month at 65 becomes $1,420 per month at 70. The increase is permanent and CPI-indexed. The higher base amount compounds over the full retirement period.
- At what age does waiting until 70 break even with starting at 65?
- The breakeven between starting at 65 and starting at 70 is approximately age 82. Before age 82, the person who started at 65 has received more total CPP. After age 82, the person who waited until 70 pulls ahead permanently. The exact breakeven age varies slightly based on the annual benefit amount but stays close to 82 regardless of the base amount.
- Can CPP be deferred past age 70?
- No. CPP benefits must begin no later than December of the month after the month you turn 70. There is no further deferral credit after 70. Canadians who have not applied by age 70 will have benefits started automatically. The 42% enhancement for deferring to 70 is the maximum available.
- What income do I need between 65 and 70 if I defer CPP?
- Deferring CPP to 70 requires covering living expenses from other sources for up to five years. Common sources include TFSA withdrawals (tax-free), RRSP or RRIF withdrawals (taxable), investment income, part-time employment, or a defined benefit pension. OAS can also be deferred to 70, adding to the period requiring bridge income, or OAS can be taken at 65 while CPP is deferred.
- Does CPP amount affect OAS clawback?
- Yes. CPP benefits are included in net income on the T1 return. The OAS recovery tax (clawback) begins at net income of $93,454 in 2026, reducing OAS by 15 cents per dollar above the threshold. A recipient with a large deferred CPP of $1,562 per month plus OAS and other income may exceed the clawback threshold. Modelling the combined CPP plus OAS and other income is important for high-income retirees.
- What is the Post-Retirement Benefit (PRB)?
- The Post-Retirement Benefit is an additional CPP benefit earned for contributions made while already receiving CPP. Recipients aged 65 to 70 who continue working can choose to stop contributing; those under 65 who are employed must continue. Each year of PRB contributions adds a small increment to the monthly benefit. The PRB is indexed to CPI and is separate from the base CPP pension.
- Does a surviving spouse receive more CPP if the deceased deferred to 70?
- A surviving spouse receives a CPP survivor's pension based on the deceased's contributions, not the start age. The combined survivor pension plus the survivor's own CPP is capped at the maximum monthly CPP benefit. If the survivor's combined pension would exceed the cap, the net benefit from the deceased's higher deferred CPP may be partially offset by the cap. Full benefit from deferral accrues primarily to the recipient who is alive to collect it.
- How do I find my CPP estimate from Service Canada?
- Log in to My Service Canada Account at canada.ca/my-service-canada. Under CPP, the Statement of Contributions shows your full contribution history and estimated monthly benefit at ages 60, 65, and 70 based on contributions to date. The estimate assumes you stop contributing immediately; actual benefits at retirement will differ if contributions continue. The statement is also available by mail on request.
