WATER CALCULATOR

Water meter reading

Find water use between readings from the same meter register.

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

How this calculation works

Current reading minus previous reading gives usage in cubic metres. Use readings from the same meter, and check for meter replacement or rollover if the latest reading is lower.

Before you use the result

This is an illustrative estimate, not a provider quote or your actual bill. Enter your current rates and charges from your plan or latest statement. Prices, billing rules and coverage can change.
