Uses a constant running power and flat energy price. Standby loads, tiered tariffs, time-of-use pricing, demand charges, taxes and fixed fees need separate treatment.
kWh = watts ÷ 1,000 × hours/day × days × duty fraction.
Energy charge = kWh × price per kWh.
Energy in kWh = watts ÷ 1,000 × daily hours × days × duty fraction. Multiply energy by the price per kWh.
A 1,000 W appliance running four hours daily for 30 days uses 120 kWh at 100% duty. At 0.15 per kWh, the energy charge is 18 currency units.
It estimates a flat-rate energy charge. Fixed fees, taxes, demand charges, tiers and time-of-use rates are not included.
