A water usage and billing calculator estimates monthly water costs based on household usage. The average American uses 80–100 gallons per day; typical water rates are $0.005–$0.015 per gallon. A family of 4 at 80 gallons/person/day uses ~9,600 gallons/month, costing roughly $50–$150 depending on local rates.
