How to Use This Electricity Bill Calculator
Enter your appliances, wattage, and daily usage hours, plus your electricity rate. The calculator estimates your monthly and annual electricity bill.
Formula & How It Works
Monthly kWh per appliance = (Watts Γ Hours/Day Γ 30) / 1000. Monthly Cost = Total kWh Γ Rate. Add fixed charges and taxes for the final bill.
Calculation Example
Refrigerator (150W, 24hr), TV (100W, 5hr), AC (1500W, 8hr), Lights (200W, 6hr): Monthly = (108+15+360+36) kWh = 519 kWh Γ $0.12 = $62.28.
Expert Tips
