Deferring CPP to age 70 increases your monthly benefit by 42% compared to taking it at 65 — permanently, and indexed to inflation for life. For Canadians in good health with other income sources to bridge the gap, deferral is often the single highest-return financial decision available in retirement.

The Numbers Behind the 42% Increase

CPP increases by 0.7% for every month you delay past age 65, up to age 70. Over 60 months, that compounds to a 42% permanent increase.

These numbers reflect the maximum. Your actual benefit depends on your contribution history. But the 42% uplift applies regardless of your base amount.

The Break-Even Calculation

The break-even point between starting CPP at 65 versus 70 is approximately age 82 to 83. Beyond that age, every additional month of life produces more cumulative income under the deferred scenario.

The average Canadian male reaching age 65 can expect to live to approximately 84. The average Canadian female reaching 65 can expect to live to approximately 87. By those averages, most retirees who defer to 70 will collect more total CPP over their lifetime than if they had started at 65.

What the Break-Even Misses

Inflation Indexing Amplifies the Advantage

CPP is indexed to the Consumer Price Index. A 42% higher base benefit means 42% more inflation protection — permanently. In a sustained high-inflation environment, this gap widens over time.

Survivor Benefit

When you die, a portion of your CPP passes to a surviving spouse as a survivor’s pension. The larger your CPP at death, the larger the survivor benefit. For couples where one spouse has significantly higher CPP entitlement, deferral protects the surviving spouse’s income for decades.

OAS Interaction

If deferring CPP requires drawing down RRSP or RRIF assets to fund living expenses in the interim, those withdrawals reduce future RRIF balances — which can lower mandatory withdrawals later and reduce OAS clawback exposure.

What You Need to Bridge the Gap

The practical challenge of deferring to 70 is funding five years of living expenses without CPP. Your bridge options are:
