About the Shower Water Cost Calculator

Shower water use depends on how long you shower and how fast your showerhead flows. Multiplying that by your local water rate gives a real dollar cost per shower and per year.

Formula: Gallons per Shower = Minutes × Flow Rate (GPM); Cost per Shower = (Gallons ÷ 1000) × Price per 1,000 Gallons

Switching to a low-flow showerhead or shaving a few minutes off shower time can meaningfully cut this cost over a year.
