How to Calculate Appliance Energy Cost
Every electrical appliance has a wattage rating that determines how much energy it uses.
Formula
Annual kWh = Wattage * Hours/Day * Days/Year / 1,000
Annual Cost = Annual kWh * Rate per kWh

हल किया गया उदाहरण
A 1,500W space heater used 3 hours/day for 365 days at $0.15/kWh.
- 01Annual kWh: 1,500 * 3 * 365 / 1,000 = 1,642.5 kWh
- 02Annual cost: 1,642.5 * $0.15 = $246.38
- 03Monthly cost: $246.38 / 12 = $20.53
- 04Daily kWh: 1,500 * 3 / 1,000 = 4.5 kWh
