Your lifespan is one of the most important agnostic factors in determining how much you need, how much time you can spend, how much time you need to do what you want to do and more. Estimating your lifespan with one of the best life expectancy calculators can be a great way to improve the accuracy of retirement finance and lifestyle predictions.
What is the average life expectancy?
Despite a slight decline in life expectancy in the United States, Americans live longer than any previous generation—much larger.
The average life expectancy for Americans, 65 years, is nearly 18 years for men. Moreover, women can expect another 19.5 years. This means – according to the Social Security Bureau, an average of 65-year-old men will live to 82 years old, while an average woman will live to 84.5. However, at least half of our lifespan may be longer – longer.
And there is a turning point. The longer we live, the longer we will live. Longer lifespan leads to longer lifespan. While a 65-year-old American man can expect to live until he is 82 years old, an 85-year-old man can live above 90 on average.
Another good news is that we live healthier and more robust lives. “Old” people now feel younger and more important. We do more in old age.
What does a longer, healthier life mean for retirement plans?
There is an increasing fact that longer and healthier life spans cost more money.
Suppose your family needs $60,000 per year to live, and your Social Security income is $36,000. In this case, you need an additional $24,000 in savings per year to make ends meet for every additional year.
Your lifespan represents a huge factor in planning retirement. The lifespan you will greatly affect how much your retirement needs. If you retire at 65 and only until 68, then if you are going to live to 98, you only need a small portion.

Expected medical life calculator
If you have a specific disease or condition, you may need to use a life expectancy calculator for your medical condition. Although very relevant, most of them are actually to be used by a doctor. However, if applicable, you can try one of the following:
Note: All the above calculators are based on actual data. However, it is important to declare again that these calculators are not 100% accurate. They use averages and historical data for predictions. But remember that you are completely unique, without predicted future.
What is the most accurate life expectancy calculator?
There is no single life expectancy calculator that claims perfect accuracy, as each calculator relies on different data sources, assumptions, and inputs. However, some people are more powerful than others because of the latest actuarial data, personalized healthy inputs and behavioral factors.
For example, calculators like Living to 100 Life Calculator, the Vitality Compass in the Blue Area is considered a more accurate calculator for life expectancy, as they ask detailed questions about your medical history, lifestyle habits, and family background rather than relying solely on age and gender.
While these calculators can’t predict the future, they can provide smarter estimates to help you plan your retirement and healthcare needs accordingly.
The actuarial life tables for social security are widely used and highly respected, but focus on age and gender.
So…How to plan for retirement when you don’t know how long you will live
When one of the biggest factors in your lifespan is totally agnostic, retirement plans can be futile. Here are some strategies for making rational plans:
1) Learn how to predict life expectancy in your retirement plan:
When calculating retirement financial needs, most retirement calculators, and even many retirement financial consultants, use simple averages.
You need to know this and make sure you are OK with the calculations.

2) Consider flexible plans:
You may want to develop a different retirement plan based on optimistic life expectancy and pessimistic life expectancy. For example, you might have a reliable financial plan that will take you from 65 to 80 years old. And, your backup plan may be to use home equity or other sources of wealth thereafter.
3) Quarterly update plan:
It is important to regularly evaluate and refine your retirement plan. It is recommended to do quarterly quarterly, but you should always check your financial and health status. Retirement plans are not something you have ever done. It should be part of the routine.
4) Consider retirement income, not savings:
Most people who are close to retirement focus on finding out how much savings they need.
However, you may be better at figuring out how much income you need per month and then take steps to ensure your income for a lifetime.
The two most popular sources of retirement lifetime income are:
- social Security: Social security is a life-saving income – no matter how long you live. Because it can last until your duration, it may be worth delaying the start of Social Security to maximize your monthly benefits.
- Lifetime annuity: Lifetime annuities may be another source of guaranteed lifetime income. If you can afford annuity for a lifetime, they can keep you from worrying about running out of money before death.
