Determining how much Life Insurance to purchase is an important decision. It is therefor necessary to understand
earlier attempts to determine suitable life insurance amounts.

An important name in those earlier attempts is Dr. Solomon Huebner, a former professor at the University of Pennsylvania. He is credited with developing one of the first systems for determining how much Life Insurance is appropriate based on the economic value of a human life, appropriately called the **human life value** approach.

The human life value approach involves estimating an individual’s personal earnings each year to retirement, from which the costs of self-maintenance, Life Insurance premiums, and income taxes are deducted to produce residual income. The **residual income** stream is then discounted to its present value. The **present value** of that residual income stream is the value of that human life. Life Insurance is concerned with the economic value of a human life.

That economic value results from these two factors:

- Your earning capacity
- Your Family and other's depending on that earning capacity

As we can see, an individual’s earning capacity alone does not create the economic value that serves as the basis of Life Insurance. The fact that earning capacity must be relied upon by others also factors into economic value.

There are some obvious relationships in which we would be likely to encounter both of those factors: earning capacity and dependence. Specifically, in both families and businesses we find an individual’s earning capacity that is relied upon by others.

Most reasonable people would probably agree that an individual should protect his or her earning capacity for the benefit of dependents by owning the appropriate amount of life insurance. The problem lies in how to determine just how much is appropriate. In other words, how do you measure your economic value?

We just reviewed the human life value approach, which will help you to better understand the importance of needs analysis. However, moving on to the actual calculation of the Life Insurance you will need under the human life value approach, understand that this approach is based on the idea that you should own an amount of life insurance equal to the **capitalized value** of your net earnings.

How much capital would be needed to replace earnings? It is the present value of that stream of net earnings.

Capitalizing the value of your net earnings requires five steps:

- 1. Estimate average annual earnings over your working lifetime.
- 2. Deduct income taxes, insurance premiums, and self-maintenance costs.
- 3. Determine the number of years until your retirement.
- 4. Decide on an appropriate discount rate.
- 5. Calculate:

(1 – 2) × present value of $1 [based on 3 and 4] = human life value

Let’s briefly examine each of these 5 steps.

There are certain rules of thumb that can assist you with this calculation. Estimate your average annual earnings, factor in the following facts.

- Professionals historically reach their maximum annual earnings at about age 55.
- Entrepreneurs and Executives usually reach their maximum annual earnings just before retirement.

- Federal and state income taxes
- Life Insurance premiums
- All of your personal costs

By deducting these amounts from the average annual earnings, the human life value approach arrives at the earnings used to support your family.

A Human Life Value Case Study

Dr. Joseph Smith’s Life Insurance Need with the Human Life Value Approach

In estimating Dr. Joseph Smith’s Life Insurance need using the human life value approach, his average income to retirement is estimated. In this case, it is estimated at $500,000. At Dr. Smith’s current income of $400,000, it is likely that two-thirds of his income is used to maintain his family. So, the family’s claim on the average family income is $333,330.

The task is to determine the present value of that 30 years of family maintenance that the family would lose if Dr. Smith were to die today. Because the current investments return approximately 5 percent, we can determine the present value at 5 percent of that stream of income over the next 30 years by using the following formula:

($500,000 × .66666) × 15.3725 = $5,124,115.42

- Two-thirds of Dr. Smith’s average income to retirement that will probably be spent maintaining his family is $500,000. × .66666.
- The factor used to determine the present value of a stream of income payments stretching over 30 years at a discount rate of 5 percent is 15.3725
- Bill’s human life value is calculated to be $5,124,115.42

* One dollar due ten years from today is worth less than one dollar due today. A compound discount table enables you to determine the value today i.e., the present value of that dollar due in the future.
