What is an Electricity Bill Calculator?
An Electricity Bill Calculator India is a simple online tool that helps you estimate your monthly or bi-monthly electricity bill based on:
- Units consumed (kWh).
- State tariff slabs.
- Fixed charges.
- Subsidies or government benefits.
Instead of manually calculating bills using complex formulas, the calculator provides instant results, which makes it index-friendly, user-friendly, and SEO-friendly for Indian users searching online.
Why Do You Need an Electricity Bill Calculator in India?
- Different States, Different Tariffs – Electricity prices vary from one state to another. Example: Delhi has lower tariffs compared to Maharashtra.
- Understand Consumption – Helps you know which slab you fall into and whether energy saving can reduce your bill.
- Budget Planning – Helps households and businesses forecast monthly expenses.
- Transparency – You can cross-check if your DISCOM bill is accurate.
- Energy Awareness – Encourages you to monitor consumption and switch to efficient appliances.
How is Electricity Bill Calculated in India?
The electricity bill in India is usually based on the following components:
1. Units Consumed (kWh)
- Each unit means 1 kilowatt-hour (1 kWh).
- Example: A 100W bulb running for 10 hours = 1 unit.
2. Tariff Slabs
Electricity is charged in slabs. Example (Delhi Domestic):
- 0–200 units → ₹3.00 per unit.
- 201–400 units → ₹4.50 per unit.
- Above 400 units → ₹6.00 per unit.
3. Fixed Charges
Distribution companies add a monthly fixed cost, usually based on sanctioned load (kW).
4. Electricity Duty & Taxes
State government duties (5%–15%) are added.
5. Subsidies
Many states (Delhi, Tamil Nadu, Rajasthan) provide subsidies for low consumption users.
Electricity Bill Formula in India
Here’s the general formula:
Example Calculation (Delhi Domestic Consumer, 350 units):
- 0–200 units → 200 × ₹3 = ₹600
- 201–150 units → 150 × ₹4.5 = ₹675
- Fixed Charges = ₹100
- Total = ₹600 + ₹675 + ₹100 = ₹1,375
- Subsidy (if applicable) = -₹200
- Final Bill = ₹1,175
This shows how slab-wise billing works in practice.

Advanced Guide to Electricity Bill Calculator in India
Understanding Electricity Tariff Structure in Detail
- Electricity tariff in India is not uniform; it is influenced by several factors:
- Type of Consumer
- Domestic (Residential): Households and small consumers.
- Commercial: Shops, offices, restaurants.
- Industrial: Factories, manufacturing plants.
- Agricultural: Farms, irrigation pumps.
- Sanctioned Load (kW)
- Higher sanctioned load = higher fixed charges.
- For example, 1 kW load may have ₹100/month fixed charges, but 5 kW may cost ₹500/month.
- Peak vs Off-Peak Hours
- Some states (like Maharashtra and Karnataka) charge Time-of-Day (TOD) tariffs for industrial/commercial users.
- Example: Higher rate from 6 PM – 10 PM, lower rate after midnight.
- State Subsidies
- Delhi: Subsidy up to 200 units (bill is waived).
- Tamil Nadu: First 100 units free.
- Rajasthan: Subsidy below 150 units.
- Uttar Pradesh: Rural subsidies.
- Taxes & Duties
- Electricity Duty: 5% – 15% depending on state.
- Fuel Surcharge Adjustment (FSA): Added based on coal/gas cost changes.
How to Read an Electricity Bill in India
Most consumers don’t understand their electricity bill properly. Here’s a step-by-step explanation:
- Consumer Number / Account ID – Unique number for billing.
- Sanctioned Load – Maximum load you can draw.
- Meter Reading
- Current Reading (CR)
- Previous Reading (PR)
- Difference = Units Consumed.
- Slab-wise Charges – Units divided into tariff slabs.
- Fixed Charges – Constant monthly charge.
- Electricity Duty / FSA – State levies.
- Subsidy – Automatically deducted (if eligible).
- Final Payable Amount – Total bill after all additions and subsidies.
Real-Life Examples of Electricity Bill Calculation
Example 1: Small Household (Delhi, 150 units)
- 0–200 units @ ₹3 → 150 × ₹3 = ₹450
- Fixed Charges = ₹100
- Subsidy (up to 200 units free) = –₹550
- Final Bill = ₹0
Example 2: Medium Household (Maharashtra, 350 units)
- 0–100 units × ₹4.50 = ₹450
- 101–200 units × ₹6.00 = ₹600
- 201–350 units × ₹7.00 = ₹1,050
- Fixed Charges = ₹150
- Duty = ₹100
- Final Bill = ₹2,350
Example 3: Commercial Shop (Karnataka, 500 units, 3 kW load)
- 0–200 units × ₹5.45 = ₹1,090
- 201–400 units × ₹6.70 = ₹1,340
- 401–500 units × ₹7.80 = ₹780
- Fixed Charges (3 kW) = ₹300
- Duty = ₹150
- Final Bill = ₹3,660
Importance of Electricity Bill Calculator for Businesses
For businesses, accurate bill estimation is critical for cost management.
- Restaurants & Shops – High electricity usage due to refrigerators and AC.
- Offices – Depend on lighting, air conditioning, and computers.
- Factories – Large machines, motors, welding, heating.
- Data Centers & IT Companies – 24×7 electricity consumption.
By using an Electricity Bill Calculator India, businesses can:
- Estimate monthly energy cost.
- Decide whether to install solar panels.
- Optimize working hours (shift energy-intensive tasks to off-peak).
- Track consumption trends.
Integration of Solar Energy and Net Metering
Many households and businesses in India are adopting solar rooftop systems. But how does billing work with solar?
-
Net Metering: If you generate more power than you consume, the extra units are sent to the grid and adjusted in your bill.
-
Example:
- Consumption = 500 units.
- Solar Generation = 300 units.
- Net Units = 200 units.
- Bill = Charges for 200 units only.This system is highly beneficial for reducing monthly bills, especially in states like Gujarat, Rajasthan, and Tamil Nadu where solar adoption is high.
Electricity Saving Calculator – How Much Can You Save?
Along with bill calculators, some tools also show potential savings. Example:
- Replacing 10 CFLs (20W each) with 10 LEDs (7W each).
- Daily usage = 5 hours.
- Monthly saving = (13W × 10 × 5 × 30) ÷ 1000 = 19.5 kWh = ~20 units.
- If per-unit cost = ₹6 → ₹120 saved monthly, ₹1,440 saved yearly.
This motivates consumers to shift towards energy-efficient appliances.
