Water Calculator

How much water do I use? How do I compare?

Estimate daily and annual water use with the Water Calculator. Answer a few simple questions and the Water Calculator does the rest. It's quick and easy.

The Water Calculator automatically compares estimated water use against an average home and an efficient home in the same region with the same number of residents. The Water Calculator also estimates the carbon footprint of household hot water use and helps identify areas where improved water efficiency may be possible.
