Thank you for exploring Survival Odds. Please contact me with any questions.
This app presents some summary actuarial values based on United States Social Security Administration cohort mortality tables (Actuarial Study 120). A link to the information source is supplied below.
I developed this program for educational purposes and thought it interesting to compare probabilities of surviving to a given age across various years of birth and as of different ages. Recently the App Store version of the App has been updated to include joint life calculations and the ability to post or print some results.
As mentioned in the application "about" section, the information is of a general nature based on averages across the population. It cannot be used to predict a given individual's life span.
The annuity value is an annuity that pays monthly starting at once (annuity due) and was calculated using the 11/24 adjustment to an annual annuity. The life insurance lump sum is derived by multiplying the traditional curtate life insurance value by i/δ where δ = ln(1+i) and i is the interest rate.
