Electricity Bill Calculator Guide (India)

Indian electricity bills are calculated on a telescopic slab system where the per-unit rate increases with higher consumption. Each state has different slab rates set by their respective State Electricity Regulatory Commissions (SERCs).

Understanding Your Electricity Bill

Energy Charges: Based on slab-wise per-unit rates for units consumed
Fixed/Demand Charges: Monthly charge based on sanctioned load (kW)
Fuel Surcharge (FAC/FPPCA): Variable charge to cover fuel cost fluctuations
Electricity Duty: State government tax (typically 6-16%)
Wheeling Charges: Some states add separate transmission charges

Typical Appliance Consumption

Ceiling Fan: 75W → ~54 units/month (24 hrs)
LED Bulb (9W): ~6.5 units/month (24 hrs)
Air Conditioner (1.5 ton): ~1,500W → ~360 units/month (8 hrs)
Refrigerator: ~150W → ~45 units/month (continuous)
Washing Machine: ~500W → ~15 units/month (1 hr daily)
