100% output for planning
Standard rate: $0.15 / kWh
Calculator results use your entered electricity rate. The default is $0.15 per kWh.
Input guide: choose actual cooking power when estimating normal energy use, or rated power when planning for maximum load. Working days determine the monthly and annual totals. Calculator results use your entered electricity rate. The default is $0.15 per kWh.
Important: This calculator uses your entered electricity rate. Reference tables and planning examples use $0.15 per kWh. Results are estimates of energy charges only; your final bill may also include demand, capacity, service or other charges.

It depends on the power selected for the estimate. A 5kW cooker at full output uses about 5kWh in one hour, while a cooker set to 2kW uses about 2kWh per hour before cycling and other operating factors.
There is no universal answer. Compare your local electricity price, gas price, equipment efficiency and operating conditions. This calculator defaults to $0.15/kWh; you can enter your local electricity rate.
No. The bill depends on the selected power, working hours, working days and the number of cookers in use. A higher rated power is only a higher maximum capacity; if the cooker normally runs below that level, select Actual cooking power.
No. It estimates energy charges from kWh using your entered electricity rate. Demand charges, capacity charges, taxes, service fees and time-of-use rules may change the final bill.
Choose Actual cooking power for the average power used during normal cooking. Choose Rated power for maximum-load or electrical-capacity planning. A qualified electrician should confirm the circuit, breaker and installation requirements.
