About This Calculator

The Drinking Cost Calculator shows you the true financial and health cost of your alcohol habit. Enter how many pints you drink per week, the price you pay, and your currency — and the calculator instantly shows your monthly and yearly spend, the life expectancy impact based on peer-reviewed research, and what that money could grow to if invested instead.

The calculator is designed with a clear purpose: to show the full cost of drinking, not to suggest cheaper ways to drink. The comparison is between your current pub habit and stopping entirely. The "If You Quit" row shows £0 — because the only financially and medically sound alternative the calculator endorses is not drinking at all.

For drinkers above the scientifically established safe limit of 5 pints per week, the calculator also shows the life cost — days and years of life expectancy lost based on the landmark Wood et al. study published in The Lancet (2018). Below the safe limit, the calculator shows a neutral note rather than a life cost figure, because the research does not support attributing significant mortality risk at low consumption levels.

  5. Tap 'Save as Image' to export a shareable summary card with your personalised figures.

The Science & Methodology

The life cost calculation is based on the study by Wood, A.M. et al. (2018), "Risk thresholds for alcohol consumption: combined analysis of individual-participant data for 599,912 current drinkers in 83 prospective studies," The Lancet, 391(10129): 1513–1523. This is one of the largest studies ever conducted on alcohol and mortality, covering nearly 600,000 participants across 19 countries. The study found that drinking above 100g of pure alcohol per week (approximately 5 pints of standard-strength beer, or 5 glasses of wine) was associated with progressively shorter life expectancy.

The study estimated that drinking 10 drinks per week above the safe limit was associated with approximately 1–2 years of reduced life expectancy, and drinking 18+ drinks per week with 4–5 years of reduced life expectancy. The calculator uses approximately 22.5 minutes lost per drink above the 5-per-week safe limit, derived from these population-level estimates. Individual outcomes vary significantly based on genetics, overall health, and other lifestyle factors.

The investment projection uses the S&P 500 historical average annual return of approximately 10%, compounded monthly (Shiller, R.J., Yale University). Past performance does not guarantee future results.

Frequently Asked Questions

How is the life cost calculated?
The calculator uses approximately 22.5 minutes lost per drink above the safe limit of 5 pints per week, based on the Wood et al. Lancet study (2018) covering 599,912 participants. It shows excess drinks per week, days lost per year, and years lost over 20 and 30 years of continued drinking at your current level.
Why is there no life cost shown for moderate drinkers?
The Wood et al. study found that the mortality risk from alcohol becomes statistically significant above 100g of pure alcohol per week — approximately 5 standard pints. Below this threshold, the research does not support attributing significant life cost, so the calculator shows a neutral note instead.
Does the calculator store my data?
No. All calculations happen entirely in your browser. Nothing is sent to a server, and no personal data is stored or collected.
Can I use this for currencies other than GBP?
Yes — select any of the 65+ currencies from the dropdown. The symbol and number formatting update automatically.
Why does the calculator only compare against quitting, not drinking at home?
Because the calculator's purpose is to show the full cost of the habit, not to suggest a cheaper way to continue it. The only financially and medically sound comparison is stopping entirely.
