* This tool is a rough, for-entertainment estimate. BAC varies greatly between individuals, and the result does not guarantee your actual level of intoxication or perception. Drink in moderation, and never drink to excess or drink and drive.

How it works

  • This is a for-fun tool that estimates blood alcohol concentration (BAC) from how much you drink, then turns that value into a playful 'attractiveness boost index' (%).
  • Pure alcohol (g) is calculated as 'volume (ml) × ABV (%) ÷ 100 × 0.8 (ethanol density) × number of drinks'.
  • BAC is found with the Widmark formula 'BAC (%) = pure alcohol (g) ÷ (body weight (kg) × r × 10)', where r is the body distribution factor (0.7 for men, 0.6 for women). We then subtract elimination over the elapsed time, estimated at 'body weight (kg) × 0.1 g/hour'.
  • The attractiveness boost index comes from our own correction factor, loosely based on the popular notion that mood peaks during the tipsy phase (around BAC 0.05–0.10%). It is not a scientifically established metric.
  • How attractive others appear and how intoxicated you feel vary widely with constitution, condition, and how empty your stomach is, so this tool's result does not reflect your actual state.
  • This tool is a rough estimate for entertainment and reference only, not a medical diagnosis. Drink in moderation (about 20 g of pure alcohol per day is a common guideline), and never drink to excess or drink and drive.
