Water Footprint Calculator
Estimate selected household water use from showers, laundry and dishwasher loads.
This calculator provides rough estimates for educational purposes only. Actual emissions and savings vary by location, energy source, equipment, behavior, and calculation method. It is not regulatory, environmental audit, or professional advice.
About the Water Footprint Calculator
Combine three visible household activities into daily, weekly and monthly water estimates.
Estimation logic
Weekly shower use equals minutes times liters per minute times seven. Laundry and dishwasher use equal loads times liters per load.
Example
An eight-minute daily shower at nine liters per minute uses an estimated 504 liters per week.
Notes
This is a partial household estimate. Toilets, taps, leaks, outdoor use, appliance cycles and local behavior are not included unless represented by the entered activities.
