CPP isn't a fixed benefit. It scales with your contribution history (max 40 years), your average earnings as % of YMPE, and when you start collecting (60-70). Most Canadians get 60-80% of the maximum. This calculator gives you a realistic estimate.
Starting at 60: −36% benefit for life (-7.2% × 5 yrs early).
Starting at 70: +42% benefit for life (+8.4% × 5 yrs late).
Break-even between age 60 vs 65: ~age 74. Live past 74? Wait. Die before? Start early.
