Explanation

Electricity bill going up? Identify the culprits! This calculator estimates the annual cost of any appliance based on its power and usage. ### Understanding kWh The Kilowatt-hour (kWh) is the billing unit. - 1000 Watts used for 1 hour = 1 kWh. - A 10W bulb on for 100 hours = 1 kWh. ### The Big Consumers 1. **Electric Heating/AC**: By far the biggest cost. 2. **Water Heater**: About 15-20% of the bill. 3. **Refrigeration**: Fridges/Freezers run 24/7. 4. **Dryer**: Very energy intensive. ### Standby Power Even when off, TVs, routers, and chargers consume power. This can add up to $50-$100 per year!

Examples

  • Heater 1500W on 8h/day for 5 months (1200h): 1800 kWh. At $0.20/kWh = $360.
  • Router (10W) 24/7 all year: 87 kWh = $17.
