Water usage calculators

Calculate the cost and volume of the water you use

If you need to calculate the volume of water used at your property outside a normal billing cycle, or what it costs, these 2 calculators are fast, simple ways to figure it out. They're eye-openers to how much a leak or filling a pool impacts your bill, and a great tool for solicitors, conveyancers and real estate agents. Calculate as far back as 1 July 2009.

Note that these tools only calculate the water usage, not service charges or the total bill for your property.


Buying, selling or moving

If you know the daily average usage for the property, use this calculator to work out the total:

  •  water used
  •  cost of the water over a specific period.

If you're buying or selling your property, your solicitor or conveyancer may use this tool to work out which portion of the water usage bill you need to pay. If you're a tenant or a real estate agent, you can use this calculator to work out the water usage up to the day the property is vacated.


Filling a pool or checking a leak

If you know the total amount of water used over a period, use this calculator to work out the total cost of the water or daily average usage. If you find a leak at your property, you can use this calculator to work out the impact on your next water usage bill. You can also check how much it will cost to fill up a pool.


Comparing new business processes or benchmarking your business

If you know the total amount of water used, use this calculator to work out the total cost of the water or daily average usage over a period. To compare different business processes, take a reading before and after each process and then use the calculator to check the cost of the water used.

You can also work out the average daily usage and compare to benchmark levels in your industry. Remember to account for days when you're closed.
