Smoking Pack Years Calculator
Understanding your smoking history is crucial for assessing health risks and making informed decisions about your well-being. The Smoking Pack Years Calculator is a practical tool designed to help you quantify your lifetime smoking exposure, estimate your risk category, and get guidance on lung cancer screening recommendations.
What Are Pack Years?
Pack years is a medical measure used to express the total amount someone has smoked over time. It’s calculated by multiplying the number of cigarette packs smoked per day by the number of years smoked. For example:
- Smoking 1 pack per day for 20 years equals 20 pack years.
- Smoking 2 packs per day for 10 years also equals 20 pack years.
This metric helps healthcare professionals estimate your risk for smoking-related diseases such as lung cancer and COPD (Chronic Obstructive Pulmonary Disease).

Example
If Sarah smokes 15 cigarettes per day and has been smoking for 20 years, and she is currently 55 years old:
- Packs per Day = 15 ÷ 20 = 0.75 packs
- Pack Years = 0.75 × 20 = 15 pack years
- Total Cigarettes Smoked = 15 × 365 × 20 = 109,500 cigarettes
- Risk Category: Low to Moderate Risk
- Lung Cancer Screening: Consult Healthcare Provider
