1. Choose a household type
Tap the closest starting point.
2. Adjust usage level
Optional, only if your home is clearly below or above typical usage.
1 = very efficient, 5 = typical Indian household, 10 = well above average. Good for matching the model to your actual bill.
3. Check the basics
4. Check your electricity rate
Indian electricity rates vary by state and consumption slab. This calculator uses a flat effective rate for estimation. Check your DISCOM tariff for exact slab details.
Rate
This is the effective per-unit price. Your actual DISCOM bill may have multiple slabs; use your average effective rate here.
Fixed charge
Most DISCOMs charge a fixed monthly amount (meter rent, demand charge, etc.) regardless of consumption.
Additional settings, only if the estimate still looks off
Kitchen & Laundry
A standard Indian fridge uses about 300 units/year. Star-rated models use less.

What to do with this estimate
If your result is higher than expected, check the advanced settings. AC, geyser, and desert cooler are usually the biggest levers. If you want updates when we add new calculators:

How the estimate works
Base usage: Depends on household size and home type (lighting, standby, basic devices)
Appliance add-ons: Additive values for AC, geyser, ceiling fans, cooler, washing machine, etc.
Month adjustment: Proportional correction if occupied less than 12 months
Range: Low and high estimates (plus/minus ~18%) account for habits, climate zone, and appliance efficiency
Cost: Estimated units times your per-unit rate plus the monthly fixed charge
Reference values for Indian household electricity
Small flat, 1-2 people: often about 100-200 units/month (1,200-2,400 units/year)
Larger flat, 3-4 people: often about 200-400 units/month (2,400-4,800 units/year)
Independent house with AC: often about 400-600 units/month (4,800-7,200 units/year)
Bungalow / villa: often about 500-800+ units/month (6,000-9,600+ units/year)
Indian household consumption is significantly lower than US or European averages. AC usage is the single biggest differentiator between low and high consumption homes.
Based on DISCOM data across states. Actual values vary widely by region, climate, and lifestyle.
Frequently asked questions
How much electricity does an average Indian household use?It varies widely. A small urban flat typically uses 150-300 units/month. Larger homes with air conditioning can use 400-800+ units/month. Rural homes without AC often use under 100 units/month.
How do electricity slab rates work in India?Indian DISCOMs charge electricity in tiered slabs. The first slab (e.g. 0-100 units) is charged at the lowest rate. As consumption increases, higher slabs are charged at progressively higher per-unit rates. This means your effective rate rises with total consumption. Each state has different slab structures.
What uses the most electricity in an Indian home?Air conditioning is by far the biggest driver, often accounting for 40-60% of the bill. Electric geysers (water heaters), desert coolers, and ceiling fans are the next biggest consumers. Homes without AC use far less overall.
How can I reduce my electricity bill?Switch to inverter ACs (save 30-50% vs non-inverter), use LED lights everywhere, buy BEE star-rated appliances, use a solar water heater instead of an electric geyser, and run ACs at 24-26 degrees C. Rooftop solar panels can also offset a large portion of your bill.
Usage notes
This calculator provides a quick orientation for usage and approximate electricity cost.
Your actual cost depends on your specific DISCOM tariff, slab structure, and state-level regulations.
For binding figures, refer to your electricity bill and your DISCOM's official tariff order.
