kWh is what you pay for: power (kW) times hours. 2,000 W is 2 kW, so every hour at full power is 2 kWh. The U.S. average residential price for Jan–Aug 2026 is 18.19¢ per kWh (EIA), which already spreads delivery and fixed charges over every kWh.
Appliances with a thermostat or compressor only draw full power part of the time; use the duty-cycle field in the calculator for those.
