Smoking Cost & Pack-Year Calculator

About the Smoking Cost & Pack-Year Calculator

Enter what you smoke or chew — cigarettes, bidis, smokeless tobacco such as gutka, khaini or zarda, or other tobacco — how many a day, what you pay and for how long. The calculator shows what it costs you a day, a month, a year and over the years, your pack-years (the measure doctors use for lifetime smoking), and whether you meet the USPSTF criteria for yearly lung cancer screening.

Set a quit date and it becomes a quit tracker: your tobacco-free time, the cigarettes or bidis not smoked, the money not spent and the health milestones from WHO and CDC as you reach them. A craving diary shows your hardest hours and triggers, and you can make a pledge card to print or keep on your phone. Everything stays in this browser — and the page lists free national quitlines, including India’s 1800-11-2356.

How the numbers are worked out

• Cost = the number a day × (price ÷ how many that price buys). A year is 365.25 days and a month a twelfth of that. The total over your years of use is at the prices you enter — in earlier years you probably paid less, so treat it as today’s value.
• Pack-years (US National Cancer Institute) = packs smoked a day × years smoked, with 20 cigarettes in a pack. 20 a day for 1 year, or 40 a day for 6 months, is 1 pack-year; 10 a day for 20 years is 10.
• Bidis have no standard pack-year. From their nicotine content, researchers in India proposed that 43 bidis a day for a year equal one cigarette pack-year, while noting that bidis give about 4.5 times as much carbon monoxide; the calculator shows bidis this way, separately.
• Quit tracker: time since your quit date, the number a day × days for what you have not used, and the daily cost × days for the money not spent.

Lung cancer screening: the USPSTF criteria

The US Preventive Services Task Force recommends a yearly low-dose CT scan for adults aged 50 to 80 who have a 20 pack-year smoking history and smoke now or quit within the past 15 years (a grade B recommendation), and stopping once a person has not smoked for 15 years or has a health problem that limits life expectancy or the ability to have lung surgery.

The decision should be shared with a clinician: screening can bring false-positive results, further tests, overdiagnosis and radiation exposure, and it does not prevent most lung cancer deaths, so quitting still matters most. The criteria were set for cigarettes; if you smoke bidis, tell your doctor how many and for how long. Other countries use different rules, so ask what applies where you live.

What happens when you quit smoking

WHO and CDC describe these changes after the last cigarette (CDC compares each with continuing to smoke):

• 20 minutes: heart rate and blood pressure drop.
• 12 hours: the carbon monoxide in your blood drops to normal; 24 hours: nicotine in the blood drops to zero.
• 2–12 weeks: circulation improves and lung function increases. 1–9 months: coughing and shortness of breath decrease.
• 1 year: the risk of coronary heart disease is about half that of a smoker; 1–2 years: the risk of a heart attack drops sharply.
• 5–15 years: stroke risk falls to that of a non-smoker; the added risk of cancers of the mouth, throat and voice box halves within 5–10 years.
• 10 years: the risk of lung cancer is about half that of a smoker, and the risk of cancers of the mouth, throat, oesophagus, bladder, cervix and pancreas decreases.
• 15 years: the risk of coronary heart disease is that of a non-smoker. 20 years: the risks of cancers of the mouth, throat, voice box and pancreas are close to those of someone who never smoked.

It is never too late: WHO estimates that people who quit at about 30 gain almost 10 years of life expectancy, at 40 about 9, at 50 about 6 and at 60 about 3, compared with those who keep smoking. Smokeless tobacco is harmful too — WHO says there is no safe level of any tobacco use.

Using the craving diary

Many people find that cravings come at the same times or with the same triggers — tea or coffee, a meal, stress, other people smoking. Log each one when it happens — it takes a few seconds — and after a few days the chart shows whether that is true for you, and your hardest hours. Plan something for those moments: a walk, water, a call, a breathing exercise. If you slip, log it honestly: a slip is a reason to adjust the plan, not to give up. The diary is stored only in this browser; download it as CSV to share with a counsellor.

Free help

WHO notes that counselling and medication can more than double your chance of quitting. Quitlines are free and confidential:

• India: National Tobacco Quit Line 1800-11-2356 (toll-free, counselling in all languages); for mCessation SMS support, give a missed call to 011-22901701.
• United States: 1-800-QUIT-NOW (1-800-784-8669) connects you to your state’s quitline.
• England: Smokefree National Helpline 0300 123 1044; Scotland: Quit Your Way 0800 84 84 84; Wales: Help Me Quit 0800 085 2219.

A doctor or pharmacist can tell you which stop-smoking medicines suit you. This page gives no medicine advice.

Limitations

• Costs come only from the prices you enter; the calculator assumes no prices and no price rises. Past spending is at today’s price.
• Pack-years assume you smoked about the same amount every year. If it changed, add up each period (packs a day × years) yourself.
• The health milestones are averages from large studies of people who stopped smoking, not a forecast for you; they do not describe stopping smokeless tobacco.
• The screening check uses the US criteria and is not a referral. Your doctor decides with you whether screening is right.
• Your entries, quit date, diary and pledge stay in this browser. Clearing site data or using another device starts afresh.
