Overview

The true cost of an insurance policy other than term life insurance is rarely immediately apparent.  The cost should include not only the premium payments but also the interest which could have ben earned on the cash value or "saving portion" of the policy.

The following HP-38E/38C program calculates this true cost, (YPTt) per $1000 of protection and the interest rate paid on the savings elements of the policy.

  2. Initialize the program; press f CLEAR ALL.
  3. Store the data:

        Key in the annual premium for policy year t and press STO 1;
        Key in the cash value at the beginning of th year and press STO 2.
        Key in the cash value at the end of the year and press STO 3;
        Key in the dividend for that year and press STO 4;
        Key in the face amount of the policy and press STO 5.
 

  1. To compute the true cost per $1000 of protection in policy year t, key in the interest rate available to you elsewhere and press R/S.
  2. To compute the interest rate paid on the savings element in the policy for that year, key in an assumed price per $1000 for an alternative low-cost policy and press R/S.
  3. To compute the true cost and interest rate for a different policy year or for a different policy, go to step 3.

Example:

Consider an average $50,000 face amount cash value policy.  The premium of $1,010 is due at the beginning of the year, and a dividend of $165 is received at the end of the policy year.  A cash value of $3,302 at the beginning of the year grows to $4,104.

Assuming a 6% savings rate available elsewhere and that insurance protection could be purchased for $3.00 per $1.00, what is the true cost/$1000 and the rate of return on your savings?
