Quick Answer: U.S. Life Expectancy by Age and Sex (SSA 2022)

Period life expectancy from the U.S. Social Security Administration 2022 actuarial table. "Years remaining" is the average additional lifespan for a person at that exact age today:

Current ageMale — additional yearsMale — life expectancyFemale — additional yearsFemale — life expectancy
At birth (0)75.475.480.580.5
3046.476.451.081.0
4037.277.241.581.5
5028.478.432.382.3
6020.580.523.983.9
6517.082.020.085.0
7013.983.916.586.5
808.588.510.490.4

Lifestyle modifiers (smoking −10 yrs, daily exercise +4 yrs, BMI ≥ 30 −4 yrs, Mediterranean diet +2 yrs) are added on top of this baseline. Use the calculator above for a personalized estimate.

Life Expectancy Calculator

Estimate your life expectancy and years remaining using SSA actuarial baselines plus lifestyle adjustments for smoking, exercise, BMI, alcohol, and diet.
Lifestyle Inputs
Your age and sex establish the baseline (CDC/SSA actuarial table). The other fields add or subtract years.

Estimate how long you'll live

Enter your age, sex, BMI, smoking, exercise, alcohol, and diet. The life expectancy calculator uses the CDC/SSA baseline and adds lifestyle factors from Lancet, BMJ, and PLOS Medicine studies.

About this life expectancy calculator

This life expectancy calculator combines the CDC/SSA 2022 period life table (your baseline by age and sex) with additive lifestyle adjustments from peer-reviewed research. Use it for retirement planning, financial planning, and motivation for healthier habits — not as a medical prediction.

1

Baseline from SSA

We use the U.S. Social Security Administration 2022 period life table, which gives remaining life expectancy by age and sex. This is the same table SSA uses to calculate pension payments.

2

Lifestyle modifiers

Lifestyle factors (smoking, exercise, BMI, alcohol, diet) add or subtract years based on Lancet 2013, Lancet 2018, PLOS Medicine 2012, and BMJ 2017 meta-analyses. Each modifier is additive.

3

Use for planning

Use the output as a planning tool for retirement savings, life insurance, and estate planning. Pair with a financial advisor for personal advice. For medical decisions, consult a physician.

Life expectancy FAQs and tips

  • Period vs cohort life expectancy: Period tables reflect current mortality conditions; cohort tables predict future improvements. Our calculator uses the period table, which is conservative.
  • Biggest lever: smoking. Quitting before age 40 recovers nearly all of the 10-year life expectancy penalty. Even quitting at 60 adds 3 years.
  • Exercise is medicine. 150 minutes/week of moderate activity adds 2.5–4 years on average (PLOS Medicine 2012).
  • BMI sweet spot is 22–25. Both obesity (BMI ≥ 30) and being underweight (BMI < 18.5) reduce life expectancy.
Life Expectancy Calculator FAQ

How does this life expectancy calculator work?

It starts with the SSA 2022 period life table (your baseline by age and sex) and adds peer-reviewed lifestyle modifiers for smoking, exercise, BMI, alcohol, and diet. The total is your estimated life expectancy from birth.

What is the average life expectancy in the USA?

As of 2022, U.S. life expectancy at birth is 77.5 years (76.1 male, 80.5 female — CDC National Center for Health Statistics). By age 65, expected additional years are about 19 for men and 21 for women.

Which lifestyle factor matters most?

Smoking has the biggest impact: current smokers lose about 10 years versus non-smokers (Lancet 2013). Obesity (BMI ≥ 30) reduces life expectancy by about 4 years. Daily exercise adds about 4 years.

Is this an accurate life expectancy prediction?

No calculator can predict individual life expectancy. This tool uses population averages plus your lifestyle modifiers. Real outcomes depend on genetics, healthcare access, accidents, and many factors this calculator does not capture. Use it for retirement and insurance planning, not medical decisions.

Should I use this for life insurance or retirement planning?

Yes — this is a reasonable starting point. Most financial planners use period life tables (like SSA 2022) plus an assumption that you will live 2–5 years longer than the average for your cohort. Always pair calculator output with advice from a licensed financial advisor.
