About the Calculator
Smoking is a serious addiction that accounts for roughly 480,000 deaths annually in the US alone and millions more around the globe. One thing we tend to forget, however, is how regular smoking can affect our budget. This Quit Smoking And Save Calculator shows you exactly how much money you could accumulate if you quit today and invest the money you would have spent on cigarettes.
How the Quit Smoking and Save Calculator Works
We collect the number of cigarettes (or packs) you smoke and assume you invest the money you don't spend on them. The default return on investment (ROI) is set to 4% per year — feel free to change it to match your own expectations.
As is often the case, people greatly underestimate the power of compound interest. Let's take a typical scenario: a pack of cigarettes costs $6.50, and John smokes one pack per day (20 cigarettes). He is 25 years old and wonders: What could I buy at 55 if I quit now and saved that cash?
- The plain, uninvested money alone gives a pretty nice sum: over $71,000.
- But when invested at 4% per annum, the total reaches $137,000 — that's 137,000 reasons to quit smoking now!
Where the 4% ROI Comes From
Warren Buffett, one of the most successful investors in the world, shared his predictions on the average return from stocks in a Bloomberg article. He estimates the return at a level of 7%, which is also consistent with long-term historical data. After taking inflation of approximately 3% into account, we get a 4% real ROI that we use as the default in this calculator.
An additional problem to keep in mind is that the price of cigarettes increases every year due to new taxes imposed by governments trying to tackle the smoking problem. The trend is simple: if you keep smoking the same amount for years to come, it will only cost you more.
American vs. Metric Measurement System
The calculator supports two input modes:
- American (packs/day): Enter the number of packs you smoke per day. This is the common unit in the United States, where a standard pack contains 20 cigarettes.
- Metric (cigarettes/day): Enter the number of individual cigarettes you smoke per day. This mode is preferred in Europe and many other parts of the world.
In both modes, you can adjust the cigarettes per pack field to match your actual pack size.
How Many Cigarettes Are in a Pack?
To get the most accurate results, check how many cigarettes fit in your pack. Governments often regulate this number:
- USA: The minimum is 20, but 25-packs are also in everyday use.
- Canada: 25-packs are most common.
- Australia: 25-pack is most common; however, 30, 40, and even 50-packs are sold around the country.
- UK: 20s and 10s are most common, but vending machines often sell 16 and 18-packs.
- European Union: No union-wide regulation; producers tend to adjust sizes based on local taxes.
Multiple World Currencies
The calculator supports 27 world currencies including USD, EUR, GBP, CAD, AUD, CHF, JPY, PLN, TRY, BRL, INR, CNY, and more. Select your local currency to see realistic savings estimates in money you use every day.
How the Investment Formula Works
We use the future value of an annuity formula — a standard formula from investment mathematics:
FV = PMT × ((1 + r)n − 1) / r
Where:
- PMT = annual money saved (your annual smoking cost)
- r = annual return rate (e.g., 0.04 for 4%)
- n = number of years
As you can see, the amount of interest grows at a much faster rate as the years progress, significantly increasing your total savings.
Frequently Asked Questions
How much does an average smoker spend per year?
At $6.50 per pack and one pack per day, an average smoker spends about $2,372 per year. Heavy smokers (two packs a day) spend nearly $5,000 annually. Over 30 years, that's $70,000–$150,000 before investment returns.
What if my ROI is 0%?
If you set the ROI to 0%, the calculator shows only the uninvested savings — the raw amount you would stop spending on cigarettes. Even without investing, the savings are substantial.
Does this calculator account for rising cigarette prices?
The current version uses a fixed price per pack. In reality, cigarette prices increase every year due to government taxes. You may want to enter a slightly higher price per pack to account for future price increases.
