This calculator allows you to game the outcome of continuing to smoke and drink or to game how much you will gain from stopping your vices.  There are some assumptions that must be made; most notably is the extra life earned by quitting smoking and drinking.  There are few good sources that can reliably give anything but approximations.  The hard number is therefore quite flexible and variable with factors beyond the scope of this analysis. 

 

Expect 25% more life!  This means, if you quit at age 25 or 67, you can expect 25% more life to live; this life may be defined as quality of life and/or quantity of life.

There are several inputs, and you should understand what your numbers are by visiting the references cited.
