Smoking Cost Calculator
Add up what smoking costs per day, month, year and decade, with rising pack prices, what the money could grow to invested, pack-years, and how much you have saved since quitting.
How it works
cost per cigarette = pack price ÷ cigarettes per pack · daily = cigarettes/day × cost per cigarette · monthly = daily × 30.44 · yearly = daily × 365 (+ other yearly costs) · year k cost = yearly × (1 + price increase)^(k−1) · invested value, each month: V = V × (1 + return ÷ 12) + month’s cost · pack-years = (cigarettes/day ÷ 20) × years smoked
The cost per cigarette is the pack price divided by the cigarettes in a pack; multiply by how many you smoke a day and scale up to a week, month (30.44 days) or year. For the years ahead you can let the pack price rise each year, since tobacco taxes keep pushing prices up. The investment line treats each month’s spending as a deposit made at the end of the month and grown, compounded monthly, at the return you choose (7% by default, a long-run stock-market average before inflation), to show the money’s opportunity cost. If you have already quit, switch the mode and enter your quit date to see the money saved, cigarettes not smoked and the WHO timeline of health benefits. The calculator also gives pack-years, the measure doctors use for smoking history and lung cancer screening, and a rough estimate of life expectancy lost based on a large study average of about 20 minutes per cigarette. It counts only what you spend on tobacco and any other costs you add, not medical bills.
Worked example
At 10 cigarettes a day and $8 per 20-cigarette pack: $0.40 each × 10 = $4.00 a day, $28 a week, about $121.75 a month and $1,460 a year. Ten years at today’s price is $14,600; invested month by month at 7% a year instead, the same money would grow to about $21,059. If prices rise 4% a year, the ten years cost about $17,529 instead. Ten years of half a pack a day is 5 pack-years.

Frequently asked questions
Does this include health costs?
No. It counts the price of the cigarettes, plus any other yearly costs you add such as higher insurance premiums. The real lifetime cost is far higher once medical and dental bills and lost income are included, so treat the result as a floor.
Where does the 7% come from?
It is a common long-run average for a diversified stock market before inflation. Actual returns vary from year to year and are not guaranteed, so the figure is an illustration, not a promise. You can change it under More options.
What are pack-years?
Pack-years measure lifetime smoking: packs per day (20 cigarettes) times years smoked. Ten cigarettes a day for 20 years is 10 pack-years. Doctors use it to judge lung disease risk, and US guidelines offer yearly lung cancer screening from age 50 to adults with 20 or more pack-years who still smoke or quit within the past 15 years.
How much life does a cigarette cost?
A 2025 University College London analysis estimated about 20 minutes of life expectancy lost per cigarette on average (around 17 minutes for men and 22 for women). It is an average across many people, not a precise personal figure, but it shows why cutting down and quitting both help.
How fast do savings show up if I quit?
Right away. Switch to “What I’ve saved since quitting”, enter your quit date and the calculator adds up the money kept and cigarettes not smoked. Health benefits start within hours and keep building for years, as the WHO timeline in the results shows.
