Seeing the long-term cost of smoking in one place is a powerful motivator. This calculator turns your daily habit and pack price into spending per day, week, month, year, and over any number of years — all in your own currency.
How it works
The maths is built up from a single cost-per-cigarette figure:
- Cost per cigarette = pack price ÷ cigarettes per pack
- Daily cost = cost per cigarette × cigarettes smoked per day
- Weekly = daily × 7
- Monthly = daily × 30.4375 (the average number of days in a month across a year)
- Yearly = daily × 365.25 (average days per year, including leap years)
- Over N years = yearly × N
Using the 365.25-day year and 30.44-day month keeps every figure internally consistent, so twelve months of cost always equals one year exactly.
Example
A 20-a-day smoker, 20 cigarettes per pack, 12.50 per pack, projected over 10 years:
- Cost per cigarette = 12.50 ÷ 20 = 0.625
- Daily = 0.625 × 20 = 12.50
- Weekly = 87.50
- Monthly = 12.50 × 30.4375 = 380.47
- Yearly = 12.50 × 365.25 = 4,565.63
- Over 10 years = 45,656.25
| Period | Cost |
|---|---|
| Per day | 12.50 |
| Per week | 87.50 |
| Per month | 380.47 |
| Per year | 4,565.63 |
| Over 10 years | 45,656.25 |
