Planning tip: Always add a 5–10 year buffer. If your estimated lifespan is 60, plan retirement income to age 67 to avoid outliving your savings.

Estimates are based on WHO 2023 Nigerian life expectancy data and population-level lifestyle adjustments. Individual outcomes vary. This is not medical advice.

How Is This Estimated?

This calculator starts with Nigerian baseline life expectancy at birth (WHO 2023: male 57 years, female 60 years). A conditional survival bonus is added for each year you have already lived beyond age 30 — because having survived to your current age means you are statistically likely to live longer than the population average at birth. Lifestyle adjustments are then applied:

Smoking: −7 years (consistent with global epidemiological data)
Exercise (sedentary): −3 years | Active: +3 years
Health (excellent): +3 years | Fair: −3 years | Poor: −7 years
Conditional bonus: +0.5 years for every year survived beyond age 30

Frequently Asked Questions

According to the World Health Organization (WHO) 2023 data, the average life expectancy at birth in Nigeria is approximately 57 years for males and 60 years for females. However, Nigerians who survive to adulthood typically have a significantly higher conditional life expectancy, often into their late 60s or 70s depending on lifestyle and access to healthcare.

Underestimating your lifespan is one of the biggest financial planning risks. If you retire at 60 expecting to live to 70 but actually live to 80, you could run out of retirement income. PENCOM advises planning for a minimum of 20 years of retirement income. This calculator helps you understand the range you should plan for.

This calculator uses population-level statistics and lifestyle adjustment factors for illustrative purposes only. Individual life expectancy depends on many factors including genetics, specific medical conditions, socioeconomic circumstances, and healthcare quality. Use this as a guide, not a prediction. Consult a medical professional for a personalised assessment.

Yes — always build in a buffer of at least 5–10 years beyond your estimated lifespan. With improving healthcare and rising incomes in Nigeria, many Nigerians will live longer than current averages suggest. Running out of retirement funds is a much worse outcome than having a surplus. Your RSA programmed withdrawal or annuity should ideally cover you to age 85–90.

PENCOM (National Pension Commission) guidelines recommend that Programmed Withdrawal and Annuity products be structured to provide retirement income for a minimum of 18 years from retirement, or to age 80 — whichever is longer. This ensures beneficiaries are covered even with above-average longevity.
