WATER CALCULATOR
Water tank filling water flow comparison
Compare water use and charges for two water tank filling flow rates using your own water price.
How this calculation works
Flow × minutes × uses × days gives litres for each option. Divide by 1,000 and multiply by the entered rate. The difference is A minus B; a negative value means B uses or costs more. Assumes equal operating time and constant flow. Heating, sewer charges, fixed fees and purchase costs are excluded.
