Half a carton

How much do 100 cigarettes cost?

The price depends on where you buy them, and money is only half the answer.

First, what 100 cigarettes is

Five packs, if a pack holds 20. Half a carton. In Australia and a few other markets where packs of 25 are common, 100 is 4 packs.

In time, it is five days at a pack a day:

The money

There is no single answer, because tobacco is taxed differently in every country and often differently again by state or province. The math is a straight line: 100 cigarettes is 5 packs of 20, so the cost is 5 times whatever a pack costs you.

The figures are in whatever currency your pack price is in, because the multiplication does not care. Pick the row nearest your own price and you have it.

Two notes on reading that table. The United States spans most of it on its own: a pack costs far more in New York than in Missouri, so a national average is close to useless for any individual. And Australia sits at the bottom rows, with packs commonly between about $35 and $55, which puts 100 cigarettes at roughly $175 to $275. There is a separate page on Australian prices, because the numbers there are unlike anywhere else.

The other cost

The best current estimate is that one cigarette costs about 20 minutes of life, 17 for men and 22 for women. That comes from Jackson, Jarvis and West, "The price of a cigarette: 20 minutes of life?", published in Addiction in 2025.

Multiply it out and 100 cigarettes is 2,000 minutes. That is 1 day, 9 hours and 20 minutes. On the separate figures it is 1 day, 4 hours and 20 minutes for a man and 1 day, 12 hours and 40 minutes for a woman.

That multiplication has a limit, and it matters. The 20 minute figure is an average drawn across a population of smokers. Nobody loses their whole life 20 minutes at a time, and the further you push a flat multiplication the less it means. The page on the 20 minute figure explains where it breaks down, and the calculator uses a model that caps the loss.

Why people work this out

Almost nobody searches the price of 100 cigarettes out of curiosity. They are usually standing in front of a carton deciding whether to buy it, which is the single most useful moment this number can reach.

The thing worth knowing is that the number runs the other way too. Every one of those 100 not smoked is money not spent and, on the same averages, time not lost. That is the number this site is built around: what stopping gives back.

This page reports a motivational estimate built from population averages. It is not a prediction about any one person or any one cigarette, it does not diagnose, treat or prevent any condition, and it is not medical advice. Prices are examples and no guarantee is made or offered about the accuracy of any figure or calculation on this site. Talk to a doctor or a quitline about stopping smoking. In the US, that is 1-800-QUIT-NOW.
