What do your cigarettes really cost?

The pack is the unit. The carton is the discount. The year is where the number stops being small. A pack-a-day smoker at eight dollars and thirty-nine cents a pack is spending roughly three thousand dollars a year at the register — and that is before you add the time, the health, the smell, or the opportunity cost.

Enter your daily cigarette count and pack price above. The calculator does the rest: weekly, monthly, yearly, lifetime, and the compound interest that same money could earn if you invested it instead. The number it returns is not a judgment. It is just the math.
