Cigarette Calculator
Estimate your cigarette with our free addiction medicine calculator. See reference ranges, risk factors, and next-step guidance.
Formula
Daily Cost = (Cigarettes/Day x Pack Price) / Cigarettes per Pack
The calculator computes cost per cigarette, then multiplies by daily consumption for daily, weekly, monthly, and yearly costs. Health impact is estimated using the BMJ figure of 11 minutes of life lost per cigarette.
Frequently Asked Questions
How many minutes of life does each cigarette take away?
Research published in the British Medical Journal estimates that each cigarette smoked reduces life expectancy by approximately 11 minutes on average. This figure is derived from large population studies comparing mortality rates between smokers and non-smokers. For a pack-a-day smoker (20 cigarettes), this translates to roughly 220 minutes or 3.7 hours of life lost per day. Over a year, that amounts to approximately 56 days of life expectancy reduction. While this is a statistical average and individual outcomes vary based on genetics, overall health, and other factors, it provides a powerful illustration of the cumulative health impact of sustained tobacco use.
