WATER CALCULATOR

Home car wash water calculator

Estimate water volume and the usage charge for home car wash water.

Enter amounts in the same currency throughout. Nothing is sent to our server.

How this calculation works

Flow × minutes × uses per day × days gives litres. Divide by 1,000 and multiply by the water price per cubic metre. Measure the hose or washer flow and count only minutes when water is running. Sewer, fixed fees and heating costs are excluded.
