Note on tariffs: State-specific rates are indicative and based on publicly available tariff orders. Actual billing varies by DISCOM, slab revisions, subsidies, and surcharges. Always verify with your local electricity provider before making financial decisions.

Multiply your total units (kWh) consumed by the rate per unit for each slab, then add fixed charges, meter rent, electricity duty, and fuel adjustment charges. Our calculator applies India's slab-based tariffs state by state.
1 unit of electricity equals exactly 1 kilowatt-hour (1 kWh). If you run a 1,000-watt appliance for 1 hour, you consume 1 unit (1 kWh) of electricity.
It depends on your AC's wattage and your local rate. A typical 1.5-ton AC uses about 1.2–1.5 kWh per hour. Multiply that by your state's rate per unit (e.g., ₹6) to get the hourly cost — roughly ₹7–₹9 per hour of runtime.
No. A ceiling fan uses roughly 50–90 watts, while an air conditioner uses 1,000–3,500 watts. You'd need about 10–30 fans to match the power draw of a single AC — fans cost far less to run than air conditioning.
It varies by state and slab. At ₹6/unit, 1,000 units costs about ₹6,000; at ₹8.5/unit it's about ₹8,500. Check your state's slab rates — our calculator lets you select your state for a precise estimate.
Yes, but it will add up. A 1.5-ton AC running 12 hours might use 14–18 units, which at ₹6/unit costs roughly ₹84–₹108 per night. Use a timer, set the thermostat a few degrees higher, and seal air leaks to reduce the cost.
Switch to LED lighting, unplug idle electronics, run full loads in washing machines, set your AC thermostat a few degrees higher, use natural light during the day, and upgrade to energy-star appliances. Revisit our calculator monthly to track your savings.
The electric field is the force per unit charge, E = F/q, measured in newtons per coulomb (N/C) or volts per meter (V/m). For a point charge, E = kQ/r² where k is Coulomb's constant. In your home wiring, the electric field is what pushes electrons through conductors, creating the current your meter records in kilowatt-hours.
Your electric company reads your meter (in kWh) at the start and end of the billing cycle, subtracts the previous reading from the current one, and multiplies the difference by your rate per kWh. They then add fixed charges, taxes, fuel surcharges, and any other fees to arrive at your total bill. Our calculator does the same estimate using your state's slab rates.
Electric potential is the work done per unit charge to move a charge between two points, V = W/q, measured in volts (V). For a point charge, V = kQ/r. The potential difference (voltage) between two points is what drives current through a circuit — standard household supply is typically 120 V in the US or 230 V in India.
Electric field strength is the force experienced per unit charge, E = F/q, or equivalently the voltage divided by distance, E = V/d. It's measured in volts per meter (V/m) or newtons per coulomb (N/C). A stronger field means a greater force on charges, which translates to more current flow and higher energy use.
Our electricity bill calculator India helps you estimate your monthly electricity cost in minutes. Whether you want tocalculate electricity bill by unit, calculate electricity bill by kWh, or simply understand how your energy usage translates into rupees, this free tool gives you a detailed, state-specific breakdown for Domestic and Commercial connections across Delhi, Maharashtra, Karnataka, Tamil Nadu, Kerala, Gujarat, Rajasthan, Uttar Pradesh, West Bengal, and more.
An electricity bill calculator India is an online tool that estimates your electricity bill based on how many units (kWh) you consume, the slab rates applied by your state electricity board, and any fixed charges, meter rent, electricity duty, or fuel adjustment charges (FAC). Instead of waiting for your DISCOM statement to arrive, you can calculate electricity bill by unit right now and plan your household budget accordingly.
Our tool is built as a free electricity bill calculator with no signup, no hidden fees, and no usage limits. It supportscalculate electricity bill India scenarios for all major states and union territories, pulling in state-level slab-based tariffs so your estimate reflects the actual pricing structure in your region. Select your state, choose Domestic or Commercial, enter your units consumed, and get an instant rupee estimate.
In India, electricity is billed per "unit," where one unit equals one kilowatt-hour (1 unit = 1 kWh). If you want tocalculate electricity bill by unit, you enter your total units consumed, select your state and connection type (Domestic or Commercial), and the calculator applies the applicable slab rates for that state. Because Indian state electricity boards use different slab structures — with varying fixed charges, meter rent, electricity duty, and fuel adjustment charges — our India calculator is state-aware. Choose your state to see the exact domestic or commercial tariff that applies to your connection.
The calculation works slab by slab: the first few units are charged at a lower rate, and as your usage crosses higher thresholds, the rate per unit increases. For example, the first 100 units might be priced at one slab, while everything above that is priced higher. This tier-aware approach is why our tool is more accurate than a simple flat-rate electricity bill calculator India.
Electricity tariffs in India vary significantly by state and by distribution company (DISCOM). Our tool coverscalculate electricity bill Delhi, calculate electricity bill Maharashtra,calculate electricity bill Karnataka, calculate electricity bill Tamil Nadu,calculate electricity bill Kerala, calculate electricity bill Gujarat,calculate electricity bill Rajasthan, calculate electricity bill Uttar Pradesh,calculate electricity bill West Bengal, and other major states and union territories.
Each state has its own slab structure for Domestic and Commercial connections. For instance, Delhi, Maharashtra, Karnataka, Tamil Nadu, Kerala, and Gujarat all follow different slab-wise rate schedules, fixed charges, meter rent, and electricity duty percentages. Whether you're in Mumbai, Bangalore, Chennai, Delhi, Kolkata, Hyderabad, Ahmedabad, Pune, or any other city, you get a localized estimate without the guesswork. Select your state and DISCOM to load the applicable slab rates, then enter your units to see your estimated bill.
Your final electricity bill in India is made up of several components, and our calculator breaks down each one:
Our India electricity bill calculator lets you toggle each of these charges on or off, enter a subsidy amount if applicable, and even override the slab rates with a custom cost per unit if you know your exact DISCOM rate. This gives you a complete, transparent picture before the bill lands in your mailbox.
Indian electricity connections are broadly classified as Domestic (residential) and Commercial. Domestic connections typically benefit from lower slab rates and subsidized slabs for low consumption, while Commercial connections are usually charged at a higher flat or slab rate. Our calculator supports both categories — select your connection type to see the applicable tariff and fixed charges for your state.
Knowing how to calculate your bill is only half the battle. Learning how to save electricity is what actually reduces your monthly cost. Here are practical steps tailored for Indian households:
Small habit changes add up over a billing cycle. Revisit our electricity bill calculator India each month to track how your conservation efforts lower your estimated cost.
Our tool supports Monthly, Bi-Monthly (2 months), and Quarterly (3 months) billing cycles, so you can match the estimate to your actual billing period. The result includes slab-wise energy charges, fixed charges, meter rent, electricity duty, FAC, subsidy, and the final total due — giving you a complete picture of your electricity bill India estimate before the bill arrives.
