Understanding Your Electricity Bill
An Indian electricity bill typically consists of these components:
Energy Charge
The main charge based on units (kWh) consumed, calculated using slab rates. This is typically 60-80% of your bill.
Fixed / Demand Charge
A monthly fixed amount based on your sanctioned load (kW), regardless of consumption. Varies ₹25-200/month across states.
Electricity Duty / Tax
State-imposed duty (5-16% of energy charge). Maharashtra has the highest at 16%.
Fuel Surcharge (FAC/FPPCA)
Variable charge adjusted quarterly based on actual fuel costs. Can add ₹0.50-1.50/unit to your bill.
Electricity Tariff Comparison — Major States 2026
The same 400 units of monthly consumption can cost anywhere from ₹1,125 to ₹2,970 depending on which state you live in. Below are the current residential slab rates across the eight largest electricity markets in India. Last updated: April 2026 — rates exclude fixed charges, duty, and fuel surcharge.
| State | 0–100 units | 101–300 units | 301–500 units | 500+ units | Bill for 400 units |
|---|---|---|---|---|---|
| Tamil Nadu | Free (0–100) | ₹2.25–4.50 | ₹6.00 | ₹8.05 | ₹1,125 |
| Delhi (BSES) | ₹3.00 | ₹3.00–4.50 | ₹6.50 | ₹7.00–8.00 | ₹1,750 |
| Gujarat | ₹3.05–3.50 | ₹4.15 | ₹5.20 | ₹5.20 | ₹1,892 |
| Karnataka | ₹3.20–4.50 | ₹6.20 | ₹7.50 | ₹8.55 | ₹2,310 |
| Kerala | ₹3.15–3.70 | ₹4.80–7.60 | ₹8.30 | ₹8.30 | ₹2,527 |
| Andhra/Telangana | ₹1.45–3.60 | ₹6.95 | ₹8.25 | ₹9.05 | ₹2,612 |
| West Bengal | ₹2.91–4.50 | ₹6.95 | ₹8.70 | ₹9.50 | ₹2,748 |
| Maharashtra | ₹3.36 | ₹7.34 | ₹10.37 | ₹11.86 | ₹2,971 |
What this table actually reveals: A Mumbai household pays nearly 2.6× more than a Chennai household for the same consumption — yet most people accept the bill without ever comparing. If you're moving cities, the electricity-cost delta over 10 years can be ₹2–3 lakh. State subsidies, telescopic vs flat tariffs, and free-first-100-unit policies cause these gaps. Use the calculator above with your actual state to see the real bill.
The Hidden Charges Adding 18–25% to Your Bill
Most people only check the "energy charge" line on their bill. But the total payable is typically 18–25% higher because of seven extra components that vary monthly and get buried in fine print. Here's a real ₹2,500 energy bill broken down to the total ₹2,953 payable.
| Bill Component | Amount | What It Is |
|---|---|---|
| Energy Charge (400 units) | ₹2,500.00 | Per-unit cost × consumption — the only number most people check |
| Fixed / Demand Charge | +₹130.00 | Monthly fee based on sanctioned load (₹25–50 per kW sanctioned) |
| Electricity Duty (state tax) | +₹225.00 | 9–15% of energy charge, varies by state. Not negotiable. |
| Fuel Adjustment Charge (FAC/FPPCA) | +₹60.00 | Monthly pass-through of coal/gas price changes. ₹0.05–0.50 per unit. |
| Meter Rent | +₹15.00 | If you don't own the meter outright (most don't) |
| Wheeling / Distribution Loss Charge | +₹18.00 | Covers transmission losses. Hidden in most bills. |
| PSDF / Cross-subsidy surcharge | +₹5.00 | Industrial users subsidising residential, regulator-mandated |
| Total Payable | ₹2,953.00 | +18.1% over the energy charge alone |
Fixed Charge — Can Be Reduced
If your sanctioned load is 5 kW but you only use 2 kW peak, you're paying ₹150 extra per month. Apply for load reduction at your discom office — saves ₹1,800/year.
FAC — The Surprise Hit
During fuel price spikes (Aug–Nov 2022, Apr–Jun 2024), FAC spiked to ₹1+ per unit — adding ₹400 to a ₹2,500 bill. Track this charge across months to spot anomalies.
Late Payment — Avoid It
Late payment adds 1.25–2% surcharge per month. On a ₹3,000 bill that's ₹37.50 lost. Set auto-debit or UPI standing instruction to never miss.
The 4 Appliances Causing 80% of Your Bill
Most "save electricity" articles list 20 tips. But in a typical 3-BHK Indian home running ~500 units/month, just four appliances account for ~80% of the total consumption. Optimise these and you cut the bill by 30–45%. Everything else is rounding error.
| Appliance | Typical Use | Units/month | % of total | Highest-impact fix |
|---|---|---|---|---|
| 1.5-ton AC (3-star) | 8 hrs × 30 days | 288 | ~58% | Upgrade to 5-star inverter → saves ~100 units/month (₹600+) |
| Refrigerator (3-star) | 24×7 | 115 | ~23% | 5-star inverter compressor → saves 40 units/month (₹240) |
| Geyser (2 kW) | 1 hr/day × winter | 45 | ~9% | Solar water heater or timer-based geyser → saves 35 units (₹210) |
| Washing Machine + Iron | 5×/week | 28 | ~6% | Cold-wash + dry on line → saves 15 units (₹90) |
| Top 4 combined | 476 | ~95% | Total savings possible: ~₹1,140/month (₹13,680/year) |
AC at 24°C, not 18°C
Every degree below 24°C raises AC consumption by 6%. Setting from 18°C → 24°C cuts AC power by 36%. Combine with ceiling fan — feels cooler at the same temp.
Inverter > Non-inverter
Inverter AC compressors modulate speed instead of cycling on/off. Real-world savings: 30–40% for AC, 20–25% for refrigerators. Premium pays back in 2–3 years.
Rooftop Solar — The Final Move
A 3 kW system covers a ~500-unit/month home. With PM Surya Ghar subsidy (up to ₹78,000), payback is now 4–5 years instead of 7–8. Calculate solar ROI →
The single highest-ROI upgrade: Replace a 5-year-old 3-star AC with a 5-star inverter AC. Cost delta ~₹15,000. Annual savings ~₹7,000–9,000. Payback in 18–24 months. Continues saving for the AC's full 8–10 year life — total lifetime savings often exceed the AC's original price.
Tips to Reduce Your Electricity Bill
Switch to LED
Replace all bulbs with LED. A 9W LED gives the same light as a 60W incandescent, saving 85% energy.
AC at 24°C
Every degree below 24°C increases AC power consumption by 6%. Set to 24-26°C with a ceiling fan.
5-Star Appliances
A 5-star rated fridge uses 30-40% less power than a 3-star. The upfront cost pays back within 2-3 years.
Go Solar

Frequently Asked Questions
How do I find units consumed on my electricity bill?
Look for "Units Consumed" or "kWh" on your electricity bill. It is the difference between current and previous meter readings. You can also check your digital meter directly — it shows cumulative kWh consumption.
What is the difference between telescopic and non-telescopic billing?
In telescopic (slab-wise) billing, each slab rate applies only to units within that range — e.g. first 100 units at ₹3, next 100 at ₹5. In non-telescopic billing (used in Maharashtra), your ENTIRE consumption is charged at the rate of the slab your total falls into.
Why does my actual bill differ from this calculator?
Actual bills may include additional charges like fuel adjustment cost (FAC), meter rent, arrears, government subsidy deductions, and rounding. These vary monthly and by your specific connection. This calculator gives an estimate based on published tariff rates.
Which state has the cheapest electricity in India?
For low consumption (under 100 units), Telangana, Andhra Pradesh, and Haryana have some of the lowest rates (₹1.90-2.50/unit). Delhi offers 200 units free per month. Punjab offers 300 units free. For high consumption, Gujarat and UP tend to be more affordable.
How can I reduce my electricity bill?
Switch to LED lights and 5-star rated appliances, use AC at 24-26°C, switch off appliances when not in use, consider solar panels (government subsidies available), and shift heavy usage to off-peak hours if your state offers time-of-day tariffs.
What is connected load (kW) and where do I find it?
Connected load is the total wattage of all electrical appliances in your home, measured in kilowatts (kW). It is mentioned on your electricity bill under "Sanctioned Load" or "Connected Load". Typical homes have 1-5 kW load.
