Pack Year Calculator
Pack Year Results
Smoking history is an important factor in assessing lung health and risks of chronic diseases. The Pack Year Calculator is a simple, user-friendly tool designed to help individuals and healthcare professionals calculate smoking exposure accurately. By entering basic information like the number of cigarettes smoked per day, years smoked, and cigarettes per pack, users can quickly determine their pack years and total cigarettes smoked over time.
Understanding your pack years can help with medical assessments, quitting plans, and risk evaluations for conditions like COPD, lung cancer, and heart disease.
What is a Pack Year?
A pack year is a unit used to measure the cumulative smoking exposure over time. One pack year is equivalent to smoking 20 cigarettes (1 pack) per day for one year. The formula is straightforward:
Pack Years = (Cigarettes per Day ÷ Cigarettes per Pack) × Years Smoked
This measurement helps medical professionals quantify risk and guide smoking cessation strategies.

Practical Example
Let’s say John smokes 15 cigarettes per day for 10 years, and each pack contains 20 cigarettes.
Step 1: Enter 15 in the “Cigarettes per Day” field.
Step 2: Enter 10 in the “Years Smoked” field.
Step 3: Select 20 for cigarettes per pack.
Step 4: Click Calculate.
Results:
- Cigarettes per day: 15
- Years smoked: 10
