Smoking Cost Calculator
See what smoking really costs you — weekly, annually and over a lifetime — from your cigarettes-a-day habit and the price you pay per pack, plus what quitting and investing the money instead could be worth.
Estimate only. This calculator gives estimates for information only, not financial or medical advice. The invested-instead projection is illustrative — investment growth isn't guaranteed and actual returns will vary. If you smoke, free NHS support is available to help you quit.
You're up to three times more likely to quit successfully with NHS support — nicotine replacement therapy and local stop smoking services are free.

- NHS Stop Smoking Services are free and roughly triple your chances of quitting for good.
- Nicotine replacement therapy (patches, gum, sprays) is available free on the NHS to support a quit attempt.
- Switching to vaping cuts the cost significantly versus smoking — see our Vaping vs Smoking calculator.
- Set up a standing order the day you quit so the daily saving lands straight into a savings account.
How the cost of smoking adds up
Cigarette costs are calculated per 20-cigarette pack, so the price per cigarette is the pack price divided by 20. At an average UK price, a 10-a-day habit comes to roughly £2,920 a year, and 20 a day to roughly £5,840 a year — using 365 days, since smoking tends to happen every day rather than just on weekdays. Multiplied across the years left until retirement, the total is often startlingly large — money that quitting, or switching to a cheaper alternative, could redirect straight into savings or investments instead.
