Addiction Calculator
Calculate the real financial, health, and time costs of addiction. See lifetime spending, years lost, and savings potential for any substance.
About
Addiction operates as a compound liability. A single cigarette costs fractions of a dollar, but the aggregate over 30 years exceeds $150,000 in direct spending alone. Factor in medical expenses, productivity loss, and the opportunity cost of uninvested capital, and the figure can surpass $1,000,000. This calculator applies the future-value annuity formula to your daily expenditure, producing a defensible lifetime cost estimate. It cross-references WHO and CDC epidemiological data to approximate life-expectancy reduction: roughly 11 minutes lost per cigarette, 0.5 - 1.0 years lost per standard drink per day sustained over decades.
The tool assumes steady consumption rates and does not model escalation or tapering. Health impact figures are population-level statistical averages and do not constitute medical advice. Opportunity cost assumes a constant annual return rate, which real markets do not guarantee. Pro tip: track your actual daily spending for one week before entering values. Most users underestimate consumption by 20 - 40%.
Formulas
The core financial model computes direct lifetime cost, then layers opportunity cost using the future value of an ordinary annuity.
Where cdaily = cost per day (units/day × cost/unit), and Y = number of years of usage.
Where PMT = monthly savings if habit is quit (cdaily × 30.44), r = monthly interest rate (7% annual default ÷ 12), and n = total months.
The 11-minute figure comes from the BMJ study (Shaw et al., 2000) estimating each cigarette reduces life expectancy by approximately 11 minutes. For alcohol, the model uses the Lancet 2018 meta-analysis coefficient: each standard drink above 1/day reduces life expectancy by approximately 30 minutes. For other substances, a generalized risk multiplier is applied based on WHO Global Burden of Disease data.
Where baseannual is the average annual medical cost attributed to the substance (from reference table), and severity is a multiplier from 0.5 (light use) to 2.0 (heavy use) scaled by consumption rate relative to the population average.
