Electricity Cost Calculator
Estimate the annual cost of your electrical appliances.
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.
