What your result means
The result estimates the selected household energy cost across useful time periods. It is intended for comparing usage scenarios, not reproducing a complete utility bill.

This is a planning estimate. Fixed electricity charges, maintenance, detergents and appliance purchase costs are not included.
Estimate only: Replace every default with figures for your appliance, household use and current electricity or water plan.
How the calculation works
Electricity cost per cycle is kWh multiplied by cents per kWh. Water cost is litres divided by 1,000 and multiplied by the entered dollars-per-kilolitre rate. Weekly use is annualised over 52 weeks.
Example calculation
A 0.9 kWh, 12 litre eco cycle at 30 c/kWh and $4/kL costs about $0.32 before detergent.
Choose better inputs
Use the kWh and litres for your usual dishwasher programme. Eco, intensive and quick cycles can have different energy and water consumption.
Dishwasher cost per cycle and year in NZ
Estimate dishwasher electricity and metered-water costs per cycle, month and year using the selected programme’s consumption. Use your own plan rate and appliance information so the estimate reflects your household rather than a broad national assumption.
Calculation formula and worked example
Calculation method
Electricity cost per cycle is kWh multiplied by cents per kWh. Water cost is litres divided by 1,000 and multiplied by the entered dollars-per-kilolitre rate. Weekly use is annualised over 52 weeks.
Worked example
A 0.9 kWh, 12 litre eco cycle at 30 c/kWh and $4/kL costs about $0.32 before detergent.
Important checks before using the estimate
Check the assumption
Energy-label figures use standard test conditions and actual use can differ.
Check the assumption
Detergent, rinse aid, maintenance and purchase cost are excluded.
Use your current rate
Copy the variable electricity rate from your own plan and keep cents per kWh separate from dollars per kWh.
Keep other costs separate
Fixed daily charges, maintenance, consumables and appliance purchase costs are not included unless the calculator explicitly asks for them.
New Zealand electricity sources
Use an appliance label or measured consumption with the variable rate from your current plan. The NZ electricity-rate guide explains how to choose the appropriate rate.
Frequently asked questions
Should I use the eco programme figure?
Use the figure for the programme you normally run. Eco programmes often take longer but may use less electricity and water.
Does this compare hand washing?
No. A fair comparison needs measured hot-water volume, temperature and washing method.
What water rate should I enter?
Use the combined volumetric water and wastewater rate that applies to your property, or zero if you are not charged by volume.
