Costs nothing, just sign up, create a password and take the test. You start with your chronological age and as you answer questions the test shows you what your real age actually is. Can be higher and HOPEFULLY lower (in my case <g>) that your chronological age.
I haven't quit long enough yet to offset the years I've smoked. I was about 9 years younger than my actual age until I hit the smoking questions. I lost about 5 years.
But, I was still younger by 3 years.
The cool thing about the test is seeing the many different areas where one can take off OR add years to ones life.
