BMI Calculator
Body Mass Index with WHO classification and healthy weight range.
Track your journey to a smoke-free life. See your real-time financial savings, cigarettes avoided, estimated lifespan regained, and watch your body's physical health recovery progress.
The counter updates every second to visually reinforce the benefits of your commitment to better health.
Health recovery timelines are sourced from the World Health Organization (WHO), American Cancer Society, and the CDC. Timeframes represent standard clinical averages for healthy adults quitting smoking.
Nicotine and carbon monoxide begin to clear from your blood almost immediately. Within three days, breathing becomes easier as your airways relax. Over the following weeks and months, lung cilia (microscopic hairs that clean out dust and mucus) begin to function normally again, greatly reducing respiratory infections and chronic coughs.

The calculator estimates savings by finding the cost of a single cigarette: Cost = Pack Price ÷ Pack Size. It then calculates the daily cost based on your daily cigarette count and multiplies it by the elapsed days, hours, and minutes since your quit date. This provides an accurate, real-time counter of your financial savings.
The 11 minutes per cigarette statistic is based on a widely cited medical study published in the British Medical Journal (BMJ). Researchers estimated that the difference in average life expectancy between smokers and non-smokers equates to approximately 11 minutes lost per cigarette consumed over a lifetime of regular smoking.
Within 20 minutes, your blood pressure and pulse rate drop back to normal. Within 12 hours, toxic carbon monoxide levels in your blood normalize. By 48 hours, nerve endings begin to heal, improving your senses of taste and smell. By 72 hours, bronchial tubes relax, making breathing significantly easier.
According to the World Health Organization (WHO) and CDC, your excess risk of coronary heart disease is halved exactly 1 year after quitting smoking. By 15 years, your cardiovascular risk falls to the level of a person who has never smoked in their lifetime.

Live Journey Status
Your heart rate and blood pressure begin to drop back to normal levels, and circulation in hands and feet improves.
The carbon monoxide level in your blood drops to normal, allowing oxygen levels to rise back to healthy levels.
Nerve endings start to regrow. Your ability to smell and taste food is significantly enhanced.
Bronchial tubes relax, breathing becomes easier, and your energy levels increase as lung capacity expands.
Your blood circulation improves, and your lung function increases up to 30%. Walking and physical activity become easier.
Coughing, sinus congestion, and shortness of breath decrease. Lungs are better at cleaning themselves, reducing infection risk.
Your excess risk of coronary heart disease is halved compared to that of a person who continues to smoke.
Your stroke risk is reduced to that of a non-smoker in most cases, as blood vessels return to a healthier, wider state.
Your risk of dying from lung cancer is about half that of a current smoker. Risk of mouth, throat, and bladder cancer decreases.
Your risk of coronary heart disease is now identical to that of someone who has never smoked in their life.
