Cost of smoking: what you could have if you invested it
Calculate how much money you could accumulate long-term if you invested, instead of spending on smoking, the same amount every month.

The final capital is calculated compounding monthly: initial capital — (1 + r)^n, plus the future value of monthly contributions [(1+r)^n - 1] / r, where r is the monthly interest rate and n the number of months.

Cost of smoking: what you could have if you invested it
This page translates a recurring monthly smoking expense into a long-term opportunity cost: not just what you spend, but what that money could have generated if invested each month instead. The fields are pre-filled with an example (€150 a month, roughly a pack a day at average price, over 30 years at 7% annually); adjust the monthly amount and price to your own case.
Spending €150 a month on smoking over 30 years means a direct outlay of €54,000. But if that same amount had been invested every month at 7% annually, the final result would be €182,995.65: €128,995.65 more than the plain accumulated spend, purely from compound interest over 30 years of steady contributions.
The real cost of a recurring habit isn't just what you spend, but also what that money stops generating over time if invested instead. The sooner that spending is redirected into savings or investing, the more years compound interest has to work, and the bigger the final difference.
This calculator doesn't quantify the health cost of smoking (doctor visits, treatment, possibly shorter life expectancy), which adds to the financial cost shown here and which, for many people, is as important a reason as the financial savings when considering quitting.
Frequently asked questions
Does this calculation account for tobacco prices rising each year?
No, it assumes a constant monthly contribution throughout the period. To approximate rising prices, you can increase the example's monthly contribution figure.
Why is the final result more than triple the amount actually spent?
Because each monthly contribution earns interest, and that interest earns further interest for the rest of the period - the cumulative effect of compound interest, more noticeable the longer the time horizon.
Can I use this same calculator for another recurring expense besides smoking?
Yes, the logic is the same for any fixed monthly expense: replace the monthly contribution with your actual expense amount and adjust the rate and years to your horizon.
Does this result include the health cost of smoking, not just the financial one?
No, this calculator only models the direct financial cost and its opportunity cost if invested instead. The health cost (doctor visits, treatment, quality of life) is additional and isn't quantified here, though for many people it's as important a reason as the financial savings.
