WATER CALCULATOR

Under-sink leak water loss

Estimate water lost and the usage charge for a under-sink leak.

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

How this calculation works

Average litres per hour × 24 × days ÷ 1,000 gives cubic metres; multiply by the price per cubic metre. Capture and measure flow where safe; the tool assumes a constant rate. Sewer, fixed and repair costs are excluded.
