How much of your life has smoking cost?
Eleven minutes per cigarette — the British Medical Journal estimate, applied to your history.
Based on a British Medical Journal study: each cigarette costs about 11 minutes of life expectancy.
Eleven minutes a cigarette. A day every few days. A year, then another.
The math is from a 2013 BMJ study — the same number your doctor would cite.
Each cigarette you smoke costs about eleven minutes of life expectancy, according to a 2013 British Medical Journal study. For a pack-a-day smoker, that adds up to roughly a day of life lost every two to three days of smoking — a quiet, ongoing trade that most people never see the bill for.
Enter your daily cigarette count, the age you started, and your current age. The calculator does the multiplication. It also shows you how many years of life you can still recover by quitting — because the body is forgiving, and most of those lost years are not yet lost.
