Smoking Cost Calculator

How much does smoking really cost?

This smoking cost calculator shows what cigarettes cost you per day, week, month and year, the total over a number of years, and how much the same money could grow to if it were invested instead. It is a simple way to see the savings from quitting.

How to use it

1. Enter the number of cigarettes per day.
2. Enter the cigarettes per pack (usually 20).
3. Enter the price per pack.
4. Enter the number of years for the long-term figures.
5. Read the annual cost, the daily, weekly and monthly cost, the total over your chosen years and the invested amount.

The formulas

• Cost per cigarette = pack price ÷ cigarettes per pack
• Daily = cigarettes per day × cost per cigarette
• Weekly = daily × 7; monthly = daily × 30.44; yearly = daily × 365
• Over N years = yearly × N
• If invested at 7% = yearly × ((1.07^N − 1) ÷ 0.07)

The invested figure assumes you put one year's cigarette money aside at the end of each year and it grows at a fixed 7% a year.

Worked example

Period	Cost (10 a day, pack of 20 at 10)
Per day	5.00
Per week	35
Per month	152
Per year	1,825
Over 10 years	18,250
Invested at 7% for 10 years	25,215

Each cigarette costs 10 ÷ 20 = 0.50, so 10 a day costs 5.00 a day and 5 × 365 = 1,825 a year.

Things to keep in mind

• Results are shown with a $ sign, but the maths works for any currency.
• The calculator uses today's pack price for every year. Real prices usually rise, so the true long-term cost is often higher.
• It does not include health, insurance or other indirect costs.
