A pack year calculator measures how many packs of cigarettes you have smoked in your lifetime.  

  • What is pack year? A pack year is a unit of measurement used to determine the amount of tobacco a person has smoked over a long period.
  • How is pack year calculated? A pack is equal to 20 cigarettes. To measure a pack year, multiply the number of packs of cigarettes smoked per day by the number of years the person has smoked.
  • Why is pack year important? Providers use pack year to determine if patients are eligible for low-dose computed tomography (LDCT) screening. The criteria are based on recommendations from the U.S. Preventive Services Taskforce.
