Standby Power Calculator — सूत्र
## How to Calculate Standby Power Cost
Standby power (phantom load) is electricity consumed by devices when they are turned off but still plugged in.
### Formula
**Annual kWh = Devices * Avg Standby Watts * 8,760 hours / 1,000**
**Annual Cost = Annual kWh * Rate**
### Common Standby Draws
- TV: 5-10W
- Game console: 2-25W
- Cable box: 15-30W
- Phone charger: 0.5-2W
- Microwave (with clock): 3-5W

हल किया गया उदाहरण
15 devices averaging 5W standby power at $0.15/kWh.
- Total standby: 15 * 5 = 75 watts
- Annual kWh: 75 * 8,760 / 1,000 = 657 kWh
- Annual cost: 657 * $0.15 = $98.55
- Monthly cost: $98.55 / 12 = $8.21
