Electricity Bill Calculator — Instant Estimate, Every State

What it does: Works out your exact electricity bill for any state or UT in India. Pick your state, choose your DISCOM, enter units consumed (or previous + current meter readings), and it returns a full itemised breakdown — slab-wise energy charge, fixed charge, FAC, electricity duty, meter rent and any free-unit subsidy, all subtracted correctly.

How it works: It loads the SERC-verified FY 2026-27 tariff for your DISCOM, applies telescopic slab billing (each slab's rate only counts for the units inside that slab), then adds fixed, FAC and duty before deducting the subsidy. A state-wide comparison bar shows what the same units would cost under other DISCOMs.

• Output: estimated bill in ₹, units billed, average ₹/unit, per-line charge breakdown with a visual slab bar.
• Extras: copy the summary, share on WhatsApp, or print a clean one-page bill-style PDF.
• Unique: every state's subsidy or free-unit scheme is applied automatically — zero bill, flat-rate, rebate or free slab — most bill calculators ignore this entirely.
• Tip: toggle "Meter readings" to calculate straight from your meter.

Example: 150 units with MPPKVVCL Central ≈ ₹600 with the Atal Grah Jyoti ₹100-bill benefit (cross 150 units and the subsidy is withdrawn entirely) — enter it above to see your exact figure.

What it does: Tells you exactly how much any single appliance adds to your bill. Enter the appliance's wattage (printed on the label or power plug), daily running hours and your ₹/unit rate.

How it works: The formula is simple and standard: watts ÷ 1000 × hours × days = units per month, then units × your rate = monthly cost. You can compare appliances side by side, so the culprit in your bill is never a mystery.

• Output: monthly units, monthly cost, daily cost and cost per hour of running.
• Works for: fridge, TV, water heater, washing machine, microwave, router — anything with a wattage label.
• Use with: the bill calculator to see the appliance's share of your total bill.

Example: a 2,000 W geyser run 1 hour daily ≈ 60 units/month ≈ ₹420/month at ₹7/unit.

What it does: Estimates the monthly units and bill for any air conditioner — 0.75 to 2 ton, 1 to 5 star, inverter or fixed-speed.

How it works: It combines the AC's rated draw (tonnage × ~1,200 W + blower) with the BEE star rating efficiency and a realistic duty-cycle — inverter ACs run at ~70% average draw while fixed-speed runs ~90% — multiplied by your hours and days. Pick your ₹/unit rate from the presets.

• Output: estimated bill/month, units/month, units/day and average power draw in watts.
• Savings view: switch star ratings to see how much a 5-star inverter saves vs a 2-star.
• Related: cooler calculator below is the cheaper alternative for light-use summers.

Example: 1.5 ton, 3-star inverter, 8 hrs/day ≈ 240–300 units ≈ ₹1,700–2,100/month at ₹7/unit.

What it does: Calculates how much your air cooler (desert or room cooler) costs to run and compares it against an AC for the same usage.

How it works: Coolers draw far less power than ACs — typically 100–250 W depending on size and fan speed. The tool multiplies watts × running hours × days × your ₹/unit rate, then shows the cooler vs AC gap so you can decide what to switch on.

• Output: monthly units, monthly cost and a side-by-side cooler vs AC comparison.
• Best for: dry-climate states (Rajasthan, Delhi, MP) where coolers work all summer.
• Related: fan calculator for the lowest-cost cooling option.

Example: a 180 W cooler, 10 hrs/day ≈ 54 units/month ≈ ₹378/month — vs an AC at 4–5× that.

What it does: Shows the monthly cost of your fans — the most-used appliance in every Indian home and one of the easiest to underestimate.

How it works: Ceiling fans draw roughly 55–75 W, table fans 35–50 W, wall and exhaust fans 20–40 W. Enter fan type (or wattage directly), speed setting, running hours and fan count — the tool does the watts × hours × days math and even includes a comparison table of fan types.

• Output: units/month and cost/month for each fan, plus the total for all your fans.
• Tip: a 5-star ceiling fan saves ₹40–60/month vs an old standard fan on 8-hour daily use.
• Related: appliance calculator for any other device's running cost.

Example: 3 ceiling fans (70 W each) at 8 hrs/day ≈ 50 units/month ≈ ₹350/month at ₹7/unit.

What it does: Estimates what cooking on an induction stove adds to your electricity bill, based on your power level and cooking hours.

How it works: Induction cooktops draw 500–2,000 W depending on the power setting. The tool multiplies the selected power × cooking hours per day × days × your ₹/unit rate, and compares the monthly cost against cooking with LPG so you can see which is cheaper for your kitchen.

• Output: monthly units, monthly cost, and an induction vs gas cost comparison.
• Best for: kitchens using induction daily for chai, dal and one-pot meals.
• Related: bill calculator to add this to your full household estimate.

Example: 1,400 W level, 1.5 hrs/day ≈ 63 units/month ≈ ₹440/month at ₹7/unit.

What it does: Sizes a roof-top solar system for your home and shows the monthly savings and payback period, before you spend a rupee on installation.

How it works: Enter your monthly consumption (or let it pull your state's average). The tool converts units to the required kW capacity using your state's sun-hours (5.5–6.2 peak hours in MP, Rajasthan and Gujarat), estimates monthly generation, applies your slab tariff to compute savings, and shows the years to payback — including the PM Surya Ghar subsidy of up to ₹78,000 for a 3 kW system.

• Output: recommended system size, units generated/month, savings/month and payback years.
• Works for: every state — generation estimates adjust for your region's sun-hours.
• Related: bill calculator to model your bill after going solar (net metering).

Example: 3 kW in MP generates ~400–460 units/month and typically pays back in 5–7 years with the subsidy.

What it does: Works out the monthly cost of charging an electric vehicle at home and compares it with petrol running costs for the same distance.

How it works: Enter your weekly distance, the vehicle's efficiency (units per 100 km), charging efficiency (~90%) and your ₹/unit rate. The tool calculates kWh needed per month, the charging cost, and what an equivalent petrol car would spend (assumes ~20 km/l at current fuel prices).

• Output: monthly charging cost, monthly units, and EV vs petrol savings per month and per year.
• Works for: scooters, hatchbacks and SUVs — any EV with a known efficiency.
• Related: solar calculator to charge your EV from roof-top solar.

Example: 1,000 km/month in a 12 kWh/100 km EV ≈ 133 units ≈ ₹930/month at ₹7/unit — vs ~₹8,000+ for petrol.
