Frequently Asked Questions — Electricity Bill Calculator India

Everything you need to know about calculating your bijli bill state-wise.

To calculate your electricity bill: (1) Find units consumed from your meter or previous bill. (2) Select your state above for the correct SERC tariff. (3) Apply slab-wise rates — the first 100 units are charged at one rate, the next 100 at a higher rate, and so on. (4) Add fixed charges, fuel surcharge, electricity duty, and applicable taxes. Our free calculator does all this automatically in seconds.
As of 2026, states like Himachal Pradesh, Uttarakhand, Arunachal Pradesh, and Mizoram have among the lowest domestic electricity tariffs due to abundant hydro power. Tamil Nadu offers free electricity for the first 100 units per month. Delhi consumers also benefit from subsidies for low consumption. Use our state calculators to compare exact 2026 slab rates for each state.
A bijli bill calculator (bijli = electricity in Hindi) is a specialized tool that applies India's slab-based tariff system. Unlike a simple multiplication, it calculates at different rates for different unit ranges — e.g., ₹4/unit for 0–100 units, ₹5/unit for 101–200 units, ₹6/unit for 200+ units. It also adds fixed charges, fuel surcharge, and state-specific taxes automatically.
Yes. All calculators on electricbillcalculate.in are updated with 2026 SERC-approved tariff orders for domestic consumers. We monitor tariff revisions from all state electricity regulatory commissions and update our data as soon as new tariff orders are issued. Last updated: June 2026.
Yes! You can estimate units by adding the wattage of your appliances. For example: 3 fans × 75W × 8 hrs/day × 30 days ÷ 1000 = 54 units. Add your fridge, AC, TV, water heater etc. Our appliance-based calculator on the homepage helps you automatically estimate total monthly consumption.
States like Maharashtra, Rajasthan, West Bengal, and parts of Uttar Pradesh tend to have higher per-unit rates in the upper consumption slabs (above 300 units). However, for low-consumption households (below 100 units), many states offer subsidised or even free electricity. Use our state-specific calculators for exact comparisons.
Yes — Delhi provides 200 free units per month to domestic consumers with a single electricity connection under the Mukhyamantri Bijli Subsidy scheme (subject to eligibility). For consumption above 200 units, regular BRPL/BYPL/TPDDL tariffs apply. Use our Delhi electricity bill calculator for the exact 2026 slab-wise calculation.
Top tips to reduce bijli bill: (1) Replace old fans/bulbs with BEE 5-star rated LED/BLDC fans. (2) Use inverter AC with 5-star rating. (3) Avoid keeping AC below 24°C — each degree lower adds ~6% consumption. (4) Unplug devices on standby. (5) Use solar panels — check our solar savings calculator to estimate how much you'd save. (6) Stay in lower tariff slabs by spreading consumption across months where possible.

Electricity Bill Calculation in India — Complete Guide 2026

India uses a rising block tariff (slab-based) system for domestic electricity consumers. This means the per-unit rate increases as your monthly consumption increases — designed to subsidise low-income households while charging commercial consumers more. Every Indian state and Union Territory sets its own tariffs through the State Electricity Regulatory Commission (SERC).

What is a Tariff Slab?

A tariff slab divides your monthly consumption into blocks. For example, Bihar (NBPDCL) has slabs like: 0–50 units at one rate, 51–100 units at a slightly higher rate, 101–200 units at a higher rate still, and so on. Our calculators apply each slab rate to the correct portion of your consumption automatically.

Fixed Charges vs. Energy Charges

Your electricity bill has two main components: (1) Energy Charges — based on units consumed and tariff slabs. (2) Fixed / Demand Charges — a monthly flat fee regardless of consumption. Additionally, most states add a Fuel Cost Adjustment (FAC), Electricity Duty, and sometimes a meter rent. Our calculators include all these for accurate totals.

State Electricity Boards and Discoms

Electricity distribution in India is handled by discoms (distribution companies) under state electricity boards. Examples: UPPCL in Uttar Pradesh, MSEDCL in Maharashtra, BESCOM in Bangalore, TANGEDCO in Tamil Nadu, NBPDCL/SBPDCL in Bihar. Each discom may have slightly different sub-zone rates within the same state — our calculators account for the most common residential rates.

How Often Do Tariff Rates Change?

SERC tariff orders are typically revised annually, though some states go 2–3 years without a revision. Major revisions often happen in April (start of Indian fiscal year) or following regulatory commission hearings. We update our calculators as soon as new tariff orders are published — check the "Last updated" date on each state calculator page.

Unit Calculation Formula

1 unit of electricity = 1 kWh (kilowatt-hour) = 1000 watts consumed for 1 hour. Formula: Units = (Wattage × Hours Used Per Day × Days) ÷ 1000. Example: A 1500W air conditioner running 8 hours/day for 30 days = 1500 × 8 × 30 ÷ 1000 = 360 units.

Popular State Calculators
