WATER CALCULATOR

Toilet flush water calculator

Estimate water volume and the usage charge for toilet flush 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. Enter litres per flush as the flow and use one minute per flush; include the number of flushes per day. Sewer, fixed fees and heating costs are excluded.
