Energy Cost Calculator

Energy = Power × time, billed per kilowatt-hour (kWh) — the standard utility billing unit. Enter a load's power draw and how long it runs to estimate energy use and cost at a given rate.

Energy (kWh) = P × t Power (kW) time (h) × rate ($/kWh) = Cost
Energy is power integrated over time (the area of the rectangle); cost is energy at a per-unit rate.
