Electricity Bill Calculator — Instant Estimate, Every State

India's most complete electricity bill calculator — all 36 states, every DISCOM, subsidy included

BijliCalc.in is a free, 100% browser-based electricity bill calculator for every state and union territory in India. Pick your state, choose your DISCOM (electricity board), enter your monthly units — or your meter readings — and you instantly get an itemised estimate exactly the way your board calculates it: slab-wise energy charges, fixed charge, fuel & power adjustment (FAC), electricity duty, meter rent and the state subsidy or free-unit scheme applied at the end.

Most "bill calculator" websites give you a rough average — units multiplied by one rate. That is not how Indian electricity bills work. Every DISCOM bills on a telescopic slab tariff, adds board-specific fixed charges, and many states now deduct a free-unit subsidy. Our calculator mirrors that real billing logic, and every tariff is cross-checked against the latest SERC tariff order before it goes live.

• All 28 states and 8 union territories — from Delhi and Maharashtra to Ladakh and Lakshadweep.
• Every major DISCOM: BSES, Tata Power-DDL, MSEDCL, BESCOM, TANGEDCO, KSEB, UPPCL, PSPCL, MPPKVVCL and more.
• Free-unit and subsidy schemes auto-applied — Delhi 200 units, Karnataka Gruha Jyothi, Telangana Gruha Jyothi and others.
• Meter-reading mode: enter previous and current readings and we compute the units for you.
• No sign-up, no tracking, no data leaves your device. The calculation runs entirely in your browser.

Use the calculator above to estimate this month's bill, or jump straight to your state's dedicated page for its exact tariff table, subsidy details and a pre-filled calculator.

How to use the bill calculator — three steps

1. Pick your state. Select from the State / UT dropdown — 36 options covering all of India. Your DISCOM list updates automatically.
2. Choose your connection and units. Domestic or commercial (approx.), then type your monthly consumption in kWh — or switch to "Meter readings" and enter the previous and current readings from your last two bills.
3. Read your itemised estimate. You'll see the total payable, average rate per unit, fixed charge and subsidy — plus a full line-by-line breakdown and a visual slab bar chart. Print it as a clean A4 bill-style PDF, copy it, or share it on WhatsApp.

The subsidy checkbox is smart: it switches itself on automatically when your selected DISCOM has an active free-unit scheme, and switches off with a clear note when it does not. You can always override it manually.

Why the estimate matches your official bill — telescopic slab billing explained

Indian DISCOMs bill energy through telescopic slab tariffs. Each slab has its own rate, and the rate applies only to the units inside that slab's range — not to your entire consumption. This is the single most misunderstood part of an electricity bill.

Take a typical tariff of 0–100 units at ₹4.00, 100–200 at ₹5.50, 200–400 at ₹7.00. For 250 units you pay: 100 × ₹4.00 + 100 × ₹5.50 + 50 × ₹7.00 = ₹1,300 energy charge. A naive calculator multiplying 250 × ₹7.00 would overcharge you by ₹450. Our engine computes each slab separately and shows you the per-slab breakdown, exactly like your bill's ledger.

On top of energy, your bill typically adds: fixed charge (per month, flat or per kW of connected load), FAC (fuel adjustment, per unit, varies monthly), electricity duty (a percentage of the bill, state-specific) and meter rent in some states. Every state page lists these exact numbers — see the verified tariff directory.

State-wise free electricity and subsidy schemes 2026-27

Nearly a third of Indian households now benefit from a state free-unit or subsidy scheme. The exact numbers vary by state and are updated by us whenever a SERC tariff order or government notification changes them. Current schemes, auto-applied by our calculator:

• Delhi — ≤200 units: entire bill ₹0 (opt-in); 201–400 units: 50% discount capped at ₹800/month (BRPL, BYPL, Tata Power-DDL, NDMC). Sep 2026: Free 3 kW rooftop solar panels for 2.3 lakh households consuming ≤400 units under PM Surya Ghar.
• Maharashtra — no free units; FY 2026-27 MYT order cuts ≤100-unit tariffs ~10% now, 26% by FY 2030 (MSEDCL).
• Karnataka — Gruha Jyothi: 200 units free, entire bill ₹0 (BESCOM, MESCOM, HESCOM, GESCOM). 5-slab tariff: ₹3.30–₹9.00/unit.
• Tamil Nadu — 200 units free per 2-month bill for consumers billing up to 500 units per bill (TANGEDCO).
• Uttar Pradesh — no free units; Bijli Raahat subsidy embedded in LMV-1 net rates (₹3.70/unit rural ≤100U).
• Bihar — 125 units free per month for all domestic consumers (Mukhya Mantri Vidyut Upbhokta Sahayta Yojana, since Aug 2025). Flat ₹7.42/unit, ₹80/kW fixed, 6% duty.
• Punjab — 300 units free, whole bill ₹0 (600 units per 2-month bill) for eligible connections (PSPCL).
• Haryana — no free units; Category I rates ₹2.20/₹2.70 up to 100 units and no fixed charge below 300 units (UHBVN, DHBVN).
• Andhra Pradesh — Jagjeevan Jyothi: 200 units free per month for SC/ST households (all AP DISCOMs).
• Telangana — Gruha Jyothi: 200 units free, entire bill ₹0, no cap.
• Jharkhand — Mukhyamantri Urja Khushhali: 200 units free, entire bill ₹0, no cap.

Also live: Rajasthan's Mukhyamantri Free Electricity (100 units free, 150 for PM Surya Ghar households), MP's Atal Grih Jyoti (first 100 units for ₹100, eligible ≤150 units), Himachal's 125-unit zero bill, Uttarakhand's 50% bill subsidy ≤100 units, Chhattisgarh's half-bill on the first 200 units, and West Bengal's Hasir Alo lifeline credit. For every one of these, the calculator shows a green "Subsidy −₹…" line and a "Bill before subsidy" row, so you can see exactly how much the state is paying on your behalf. States without a scheme — Gujarat, Maharashtra, Uttar Pradesh, Haryana, Odisha, Kerala and others — show a clear "no free-unit scheme active" note instead of a false discount.

Your bill line by line — what you actually pay for

Open any official Indian electricity bill and you will see these charge components. Our breakdown mirrors them one-to-one:

• Energy charges (slab-wise): the biggest component — units consumed, billed at your DISCOM's telescopic slab rates.
• Fixed / demand charge: a monthly fee for keeping your connection alive, either a flat amount (e.g. ₹130/month for MSEDCL) or per kW of sanctioned load (e.g. ₹20/kW in Delhi).
• Fuel & Power Adjustment (FAC): a per-unit charge that recovers fuel cost variation — it changes every month with fuel prices.
• Electricity duty: a state government levy, usually 3–12% of the bill (MP charges 12%).
• Meter rent: a small monthly charge for the meter (e.g. ₹10/month in MP).
• Subsidy / free-unit scheme: the state's discount, deducted from your payable — often zeroes out low-usage bills completely.

Your total is energy + fixed + FAC + duty + meter rent − subsidy. That is precisely the formula our engine implements, and it is why a Delhi household opted into the subsidy and using under 200 units pays exactly ₹0.

Fixed charge, FAC, duty and meter rent — the fine print

Fixed charge is not a penalty — it is a fee

Boards charge a fixed amount every month for the meter and connection, regardless of usage. It is usually flat (₹15–₹130/month) or load-based (₹/kW of sanctioned load). Some boards waive it below a unit limit — Haryana bills no fixed charge below 300 units, and MPPKVVCL charges ₹134/month flat up to 150 units, switching to ₹300 per kW above that. Our load field appears automatically for boards with load-based fixed charges.

FAC changes your bill every month

Fuel & Power Adjustment passes the rising or falling cost of coal, gas and solar procurement onto consumers at a per-unit rate. It is why your bill can grow even when your consumption is identical to last month. Every tariff record on this site carries the latest FAC rate, and our estimate flags it so you know which part of your bill is volatile.

Electricity duty is a state tax

Duty is charged as a percentage of your bill (excluding subsidy), e.g. 12% in Madhya Pradesh, and funds state-level electricity infrastructure. We apply it automatically from each state's published rate.

Meter rent and other small charges

A few states add ₹10–₹15/month meter rent or small regulatory charges. Where published, these are included in the estimate — nothing hidden, every line explained.

How the subsidy toggle works

The "Apply state subsidy / free-unit scheme" checkbox is not cosmetic — it runs the real subsidy logic: the calculator works out what the scheme waives (e.g. Delhi: the whole bill up to 200 units at the ₹3.00 slab), applies per-unit rebates and caps where the scheme has them (₹800 in Delhi's 201–400 band), and deducts the result from your gross bill. The saving is shown as a green deduction line plus a "Bill before subsidy" row, so you always know what the state is paying for you.

Two things to remember: schemes have eligibility conditions (household income, sanctioned load, usage cap) — our estimate assumes you qualify. And if a scheme's cap is lower than the free-unit slab cost, we apply the cap, exactly like the board does.

10 practical ways to lower your electricity bill

1. Run your AC at 24–26°C instead of 20°C — every degree costs roughly 5–6% more power. See the exact numbers with our AC bill calculator.
2. Use an appliance cost calculator to find your top three energy guzzlers — fridge, geyser and AC usually dominate.
3. Replace old ceiling fans with BLDC (star-rated) fans — up to 40% savings. Try the fan calculator.
4. Shift to an air cooler instead of AC for the dry season — coolers use 70–90% less power. Compare with the cooler calculator.
5. Cook smarter: a pressure cooker or induction on low-med heat saves units. Check induction vs gas costs.
6. Switch geyser usage to morning hours and reduce the thermostat — it is often 20–30% of a household's bill.
7. Unplug idle electronics and routers at night; set TVs and lights on timers.
8. Replace incandescent/CFL with LED everywhere — LED pays for itself in months.
9. If your board gives a solar net-metering policy, compare rooftop solar payback for your state — many states now credit 200+ free units for solar homes.
10. If you drive an EV, charge at night at slab-discounted rates — the EV charging calculator shows monthly cost.

Plug your new consumption into the calculator after each change — watching the estimate drop is the best motivation.
