Choose your state and Domestic or Commercial. The applicable slab rates load automatically.
Enter your total kWh usage. Energy is computed slab-by-slab from the displayed rate data.
See slab-wise energy charges, duty, FAC, and the final total due.
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.
Get quick answers about electricity bill calculation, units, AC usage, and tips to lower your monthly bill.
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.
