Probability of Living to Age 90

According to Social Security Administration actuarial tables, approximately 27% of Americans born today can expect to live to age 90. The odds are significantly better for women (roughly 33%) than for men (roughly 21%). These figures have been improving steadily: a century ago, only about 5% of Americans lived to 90.

Reaching age 90 is increasingly common and has important implications for retirement planning. Financial advisors often recommend planning for a 30-year retirement (age 65 to 95) to avoid outliving savings. Social Security benefits, pensions, and annuities provide valuable longevity insurance because they continue paying regardless of how long you live.

Lifestyle factors strongly predict who reaches 90. The key factors consistently identified in longevity research are: never smoking (or quitting early), maintaining a healthy weight, regular physical activity (even walking), strong social connections, moderate alcohol consumption or abstinence, managing chronic conditions like hypertension and diabetes, and having a sense of purpose. Genetics account for roughly 20-25% of lifespan variation, meaning lifestyle choices are the dominant factor.
