How is electricity consumption (kWh) calculated?

Energy consumption in kWh = (Wattage × Hours per day × Days per month) ÷ 1000. For example, a 1500W AC running 8 hours/day for 30 days consumes 1500 × 8 × 30 ÷ 1000 = 360 kWh (units).

What is a unit of electricity?

1 unit of electricity = 1 kilowatt-hour (kWh). It is the energy consumed by a 1000W appliance running for 1 hour. Your electricity bill is calculated based on total units consumed per month.

Why does my actual bill differ from the calculated estimate?

Electricity tariffs in India are slab-based — the per-unit rate increases as consumption rises. This calculator uses a simplified flat rate. Other charges like fixed/demand charges, meter rental, taxes, and surcharges also contribute to the actual bill.

What is the average electricity consumption of a household in India?

An average Indian middle-class household with an AC, refrigerator, washing machine, TV, fans, and lights consumes approximately 200–400 units per month. Households with multiple ACs can exceed 600–800 units.

How can I reduce my electricity bill?

Key savings tips: Use 5-star BEE-rated appliances, switch to LED lighting, set AC temperature to 24°C (saves ~6% per degree above 18°C), use inverter ACs and refrigerators, and avoid standby power consumption.

What is the wattage of a 1.5-ton AC?

A standard non-inverter 1.5-ton AC consumes approximately 1400–1600W. An inverter AC of the same capacity consumes 800–1200W on average due to variable compressor speed. This calculator uses 1500W as the default.

What does BEE star rating mean for appliances?

BEE (Bureau of Energy Efficiency) star rating indicates energy efficiency — 5-star is the most efficient, 1-star is the least. A 5-star AC can be 20–30% more energy efficient than a 1-star model of the same capacity.

Are the state electricity tariffs accurate?

The tariff values shown are indicative average rates. Indian state electricity tariffs are slab-based and vary by consumer category (domestic, commercial, industrial). Check your state DISCOM website or electricity bill for the exact applicable rate.

How much electricity does a refrigerator consume?

A typical 200–300 litre single-door refrigerator consumes 30–50 units/month. A 5-star refrigerator will consume less. The default wattage of 150W represents average consumption; actual values depend on the model and usage patterns.

High Consumption Alert — Savings Opportunity

Your estimated consumption exceeds 300 units/month. Consider: upgrading to 5-star rated appliances, setting AC to 24°C instead of 18°C (saves ~36%), using LED lights, and switching off appliances at the plug when not in use. These steps can reduce your bill by 20–35%.

Disclaimer: The estimated bill is based on a flat per-unit rate. Actual electricity bills include slab-based tariffs, fixed charges, meter rental, government taxes, and surcharges. Refer to your DISCOM website or your electricity bill for exact tariff details applicable to your connection category.
