Energy Cost Calculator for Urinals

You are here

Vary water cost, frequency of operation, and /or efficiency level.

This calculator assumes that early replacement of a urinal or toilet will take place with 10 years of life remaining for existing fixture.
Input the following data (if any parameter is missing, calculator will set to default value). Defaults
Water Saving Product    Urinal
Gallons per Flush    gpf 1.0 gpf
Quantity to be Purchased    1
Water Cost (including waste water charges)    $/1000 gal $4/1000 gal
Flushes per Day    flushes 30 flushes
Days per Year    days 260 days

Gallon per Flush     gpf         
Annual Water Use     gal         
Annual Water Cost $ $ $ $
10-Year Water Cost $ $ $ $
Water Cost Savings (for replacing existing unit 10 years early) $ $ $ $

By replacing your existing , having a flow rate of gallon(s) per flush, you will have a water cost savings (per unit) of $ over 10 years.


  • "Base model" has an efficiency that just meets the national minimum standard for toilets or urinals.
  • The assumed combined water and waste-water price is $4/1000 gallons.


This cost calculator is a screening tool that estimates a product's lifetime energy cost savings at various efficiency levels. Maintenance and installation costs do not vary significantly among the same product having different efficiencies; so, these costs are not included in this calculator tool. For a detailed life cycle cost analysis, The Federal Energy Management Program developed a tool called Building Life Cycle Cost (BLCC). This downloadable tool allows the user to vary interest rates, installation costs, maintenance costs, salvage values, and life expectancy for a product or an entire energy project.
