How do I find my water rate?

Your water rate appears on your monthly utility bill, usually listed in dollars per hundred cubic feet (CCF) or per thousand gallons. Divide by the appropriate unit to get cents per gallon. The US average is around $0.005 per gallon ($5 per 1,000 gallons).

How accurate is this estimator?

The estimates use EPA WaterSense averages (2.1 gpm showerhead, 1.6 gpf toilet, 25 gal per HE washer load, 4 gal per dishwasher run). Your actual usage may vary based on appliance efficiency and behavior.
