Electricity Bill Estimator

Calculate your monthly electricity cost for any appliance. Find units consumed (kWh), cost in rupees, and yearly savings from switching to energy-efficient devices.

How to Use & Understand This Calculator

Your electricity bill is based on kilowatt-hours (kWh) โ€” commonly called "units" in India. One kWh = 1,000 watts consumed for 1 hour. A 1,500W geyser running for 8 hours uses 12 kWh. At โ‚น7/unit, that costs โ‚น84/day. Formula: kWh = Watts ร— Hours / 1,000; Cost = kWh ร— Rate.

Understanding your appliances' power consumption is the first step to reducing your bill. Here are typical power ratings of common Indian household appliances:

High Consumption: Geyser (1,500-3,000W), AC 1.5 ton (1,200-1,800W), Washing Machine (500-1,000W), Microwave (700-1,200W). Medium: Refrigerator (100-250W running, but always on), Desktop PC (200-500W), Iron (750-1,000W). Low: LED bulb (5-15W), Ceiling fan (40-75W), Laptop (30-65W), LED TV (50-120W).

The most impactful energy savings in Indian homes: Switch from geyser to solar water heater (90% savings on water heating). Replace 1.5-ton 3-star AC with a 5-star rated AC (saves โ‚น3,000-5,000/year). Use BEE (Bureau of Energy Efficiency) 5-star-rated appliances across all categories.
