Annual Cost vs Days Used per Year
Fórmula
## 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** ### Common Appliance Wattages - Space heater: 1,500W - Hair dryer: 1,200W - Refrigerator: 150W (average) - LED bulb: 10W - Desktop computer: 200W
Ejemplo Resuelto
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
Preguntas Frecuentes
Where do I find my appliance wattage?
Check the label on the appliance, the user manual, or the manufacturer website. Wattage is usually listed on a sticker near the power cord or on the bottom of the device.
Which appliances use the most electricity?
HVAC systems, water heaters, clothes dryers, and electric ovens are typically the largest energy consumers. Refrigerators use moderate power but run 24/7.
Does an appliance use energy when turned off?
Many appliances draw standby or phantom power when plugged in but off. TVs, gaming consoles, and chargers commonly draw 1-10 watts in standby mode.
