What 73 looks like on a life calendar
Each row is one year of age and each box one week. The first 73 rows are filled; the vermilion box is the first week after your 73rd birthday.
Chosen rows
For many, these rows are the first in decades not defined by a job, and there are more of them than most people expect. Life tables show that surviving to this age raises the average expected life span well above the at-birth figure, so planning for long, active years is realistic rather than optimistic.
The averages at 73
The Social Security Administration’s 2023 period life table, the one used in the 2026 Trustees Report, puts average remaining life at exactly 73 at 14.5 years for women and 12.7 years for men. That implies an average age at death of about 87.5 and 85.7 respectively, and a halfway point in remaining life at around age 43.
Of people alive at 73, the same table implies that 82% of women and 76% of men would reach 80, 39% of women and 29% of men would reach 90, and 3.5% of women and 1.5% of men would reach 100. A period table assumes today’s death rates hold for the rest of a life; if health keeps improving, the true figures will be somewhat higher.
Averages describe large groups, not you. Health, habits, income, and family history move individual odds far more than a table can show. For a fuller breakdown by age and sex, with the method explained, see Statistical Life Left.
