Energy Cost per Cycle Calculator
Estimate energy costs for an appliance cycle using its stated energy use and the tariff that applies to the same energy unit.
How to use this calculator
- Enter kWh per cycle, tariff per kWh and number of cycles.
- Confirm that all inputs use the stated units and the same population, period or scope.
- Change one assumption at a time when comparing scenarios.
Formula used by the energy cost per cycle calculator
Cost = kWh per cycle × number of cycles × price per kWh
- Cost = kWh per cycle × number of cycles × price per kWh
- Water, detergent, maintenance, standby energy and variable tariffs are outside this calculation.
- Inputs are validated against required ranges and outputs are rounded for readability.
Worked examples
Worked example
0.9 kWh per cycle across 20 cycles at 0.30 per kWh.
Total energy is 18 kWh and estimated cost is 5.40.
Total energy is 18 kWh and estimated cost is 5.40.
Understanding the result
Estimate energy costs for an appliance cycle using its stated energy use and the tariff that applies to the same energy unit.
Water, detergent, maintenance, standby energy and variable tariffs are outside this calculation.
Important notes
Water, detergent, maintenance, standby energy and variable tariffs are outside this calculation.
Use the result as a calculation aid for the inputs supplied; confirm critical specifications independently.
Frequently asked questions
Where can I find kWh per cycle?
Check the appliance label, product specification or measurement from a suitable energy meter.
