About Life Expectancy Calculator

The formula for calculating Life Expectancy is below:

Life Expectancy Calculator

C+ X – F

C is the current age of the individual.
X is the average life expectancy which can be obtained from social security tables.
F is the adjustment factore.

Life Expectancy = C+ X – F

Wherein,

C is the current age of the individualX is the average life expectancy obtained from social security tables, which are different for males and females.

Below is the table for life expectancy wherein, against the age, one can find the number of years remaining for survival.

The life expectancy calculator is a very complicated calculator wherein too many factors are involved, such as the current age, gender, and lifestyle habits such as whether the person smokes or doesn’t smoke, whether the person has any kind of disease or inherited any disease such as diabetes, high blood pressure, etc. Even drinking habits affect life expectancy. All these factors need to be considered, and accordingly, based on gender, the above table is derived, and further upon lifestyle habits adjustment is made for the same as well. The final figure would be the expected life expectancy of the individual.

How to Calculate Life Expectancy?

One needs to follow the below steps to calculate the Life Expectancy.

Step #1 – Find out the current age of the individual.

Step #2 – Determine the gender of the individual as the second step

Step #3 – Find the life expectancy figure from the above table based on current age and gender.

Step #4 – Now, determine the individual’s lifestyle habits, whether they are a smoker or non-smoker.

Step #5 – Make adjustments if it determines whether the individual is a smoker or non-smoker; then, we can ignore this step. The life expectancy determined in step 3 will be the final figure, which needs to be added to the current age.

Step #6 – If the individual were a smoker, then this resultant figure after adjustment would be the life expectancy figure, and that figure will be added to the current age.

Life Expectancy Calculator Example

Mr. Vivek, aged 29, has been living in Delaware since birth. He is 69 inches tall, weighs around 180 pounds, and has never reported any medical or health issues. He is currently staying single and doesn’t drink, but he has a habit of smoking sometimes, which is the only habit he cannot escape from. He has started his own business, and he has a family dependent upon him. He is looking for a life insurance policy, and the company has received the request from his side and the details of his life and lifestyle.

The company wants to calculate the life expectancy for Mr. Vivek and accordingly wants to calculate the life insurance premium for the policy insured for $500,000.

Note the company has a policy for adjusting the life expectancy by ten years if the person turns out to be a smoker.

Based on the above information, you are required to calculate Life Expectancy.

Solution:

We are given below details about Mr. Vivek.

He is MaleHis current age is 29 years oldHe is a smokerHe doesn’t have any pre-existing diseaseHis height is 69 inchesHis weight is 180 pounds

Based on his current age, which is 29, we can determine above the remaining number of years he is expected to live, which is 48.63; further, he is a smoker, and the adjustment factor is 10, which will reduce the life expectancy.

Now we can use the formula below to determine the individual’s life expectancy.

= 29 + 48.63 – 10= 67.63

Therefore, the life expectancy per the above calculation is 67.63 years.

Conclusion

As discussed above, life expectancy is complicated and is based upon several factors, including age, lifestyle habits, gender, and pre-existing disease, if any. Note the table above can either overestimate the life expectancy or underestimate the life expectancy as the lifestyle keeps changing, and the figures are based on 2015 also.
