Water Footprint Calculator — Formula
## How to Calculate Your Water Footprint
Your water footprint includes direct use (showers, faucets) and virtual water embedded in food and products.
### Virtual Water Examples
- 1 lb beef: ~1,800 gallons
- 1 serving meat: ~450 gallons
- 1 serving dairy: ~60 gallons
- $1 of consumer goods: ~20 gallons
### Formula
**Total = Direct Use + Food Virtual Water + Goods Virtual Water**
The average American water footprint is about 2,000 gallons per day, with only 5% from direct use.

Esempio Risolto
A person using 80 gal/day directly, eating 7 meat and 10 dairy servings/week, spending $500/month on goods.
- Direct: 80 * 365 = 29,200 gallons/year
- Meat: 7 * 52 * 450 = 163,800 gallons
- Dairy: 10 * 52 * 60 = 31,200 gallons
- Goods: 500 * 12 * 20 = 120,000 gallons
- Total: 29,200 + 163,800 + 31,200 + 120,000 = 344,200 gallons/year
