From watts to cost
Make the estimate traceable
The calculator converts watts to kilowatts, multiplies by time and quantity to estimate kilowatt-hours, then applies the tariff you entered. Monthly figures use annual cost divided by 12.
Read your tariff
Enter the energy charge per kWh. Supply, demand, solar-export and other bill charges are outside this appliance estimate.
Compare consistently
Apply the same hours, days, quantity and tariff to both appliances for a meaningful like-for-like comparison.
Questions answered
Appliance electricity cost FAQ
Why might my bill differ from this estimate?
Many appliances cycle on and off, change power with workload or use thermostats. Bills can also include supply, demand and other charges that are not caused by one appliance.
Where do I find the electricity tariff?
Look for the usage or energy charge on your electricity bill or plan. Enter the rate in cents per kWh for the applicable tariff period.
Does the calculator include solar panels or battery storage?
No. It estimates appliance consumption before solar generation, battery flows, export credits or plan-specific rules.
Does Utilaroo store my electricity information?
No. Inputs and results are calculated locally and are not submitted to or stored by Utilaroo.
