The WBSEDCL Electricity Bill Calculator is a smart online utility designed for consumers served by West Bengal State Electricity Distribution Company Limited. It helps domestic households, eligible Hasir Alo beneficiaries, commercial establishments, and EV charging operators estimate their electricity expenses before receiving the official bill.
Using the supplied West Bengal Electricity Regulatory Commission FY 2026–27 tariff information, the calculator supports Domestic telescopic tariff slabs, monthly and quarterly billing cycles, the configured Hasir Alo Scheme benefit, Non-Domestic Commercial charges, EV Charging tariffs, fixed monthly charges, Fuel and Power Purchase Cost Adjustment, and 6% State Electricity Duty.
The tool is intended for eligible WBSEDCL consumers across Kolkata suburban regions, Howrah, Siliguri, Durgapur, Kharagpur, Asansol, Malda, Darjeeling, and other covered areas of West Bengal.
Electricity usage can differ significantly between consumers. A small low-load household may qualify for the Hasir Alo Scheme, while a larger residence using air conditioners, refrigerators, water pumps, heaters, and other appliances may enter higher domestic tariff slabs. Shops, offices, hotels, clinics, showrooms, and EV charging stations follow separate tariff structures.
The calculator simplifies the complete billing process by showing slab-wise energy charges, billing-cycle scaling, fixed charges, FPPCA fuel adjustment, Electricity Duty, Hasir Alo benefit, and the estimated net payable amount in a transparent itemized report.
What Is the WBSEDCL Electricity Bill Calculator?
The WBSEDCL Electricity Bill Calculator is an online electricity bill estimation tool for consumers served by West Bengal State Electricity Distribution Company Limited.
It calculates an expected bill using total electricity consumption, billing cycle, connection category, sanctioned load, and scheme eligibility.
Unlike a basic calculator that multiplies all electricity units by one rate, this tool follows the supplied domestic telescopic tariff structure. Consumption is divided across separate slabs, and only the units falling within a particular slab are charged at that slab’s rate.
The tool also distinguishes between a one-month bill and a three-month quarterly bill. This is important because quarterly consumption limits must be scaled correctly before the applicable slabs are calculated.
Monthly and Quarterly Billing Cycle Support
The supplied WBSEDCL tariff structure lists domestic slabs as monthly-equivalent limits. When the consumer selects a quarterly billing cycle, the calculator multiplies the monthly slab limits by three.
The monthly-equivalent domestic slabs are:
- 0–25 units: ₹5.30 per unit
- 26–75 units: ₹5.85 per unit
- 76–150 units: ₹6.70 per unit
- 151–300 units: ₹7.50 per unit
- Above 300 units: ₹8.50 per unit
For a three-month quarterly bill, the equivalent tariff limits become:
- 0–75 units: First quarterly slab
- 76–225 units: Second quarterly slab
- 226–450 units: Third quarterly slab
- 451–900 units: Fourth quarterly slab
- Above 900 units: Highest quarterly-equivalent slab
The energy rates remain associated with their respective slab portions. Only the consumption limits are scaled according to the billing duration.
WBSEDCL Domestic Telescopic Tariff Calculation
Domestic electricity consumption is calculated telescopically. This means the complete consumption is not multiplied by the rate of the highest slab reached.
For example, when a consumer enters 220 units for a one-month billing period, the calculator distributes the consumption as follows:
- First 25 units: 25 × ₹5.30 = ₹132.50
- Next 50 units: 50 × ₹5.85 = ₹292.50
- Next 75 units: 75 × ₹6.70 = ₹502.50
- Remaining 70 units: 70 × ₹7.50 = ₹525
- Total energy charge: ₹1,452.50
The applicable fixed charge, FPPCA, and Electricity Duty are then added separately.
If the same 220 units represent a complete quarterly bill, the result will be different because the three-month scaled slab limits apply. Selecting the correct billing cycle is therefore essential.
How the Hasir Alo Scheme Works
The calculator supports the supplied Hasir Alo Scheme configuration for eligible subsidized low-load consumers.
Under the provided rule, the benefit applies when:
- The consumer is officially eligible under the Hasir Alo Scheme.
- The connected or sanctioned load is no more than 0.3 kW.
- Monthly usage remains within 25 units, or quarterly usage remains within 75 units.
Under the supplied calculator configuration, eligible consumption within this limit receives a 100% energy-charge benefit. The configured fixed charge is also ₹0.
The calculator can display:
- Gross energy charge before subsidy
- Eligible free units
- Hasir Alo subsidy deduction
- Fixed charge
- FPPCA and duty treatment
- Estimated net payable amount
The scheme option should only be selected by consumers who are officially registered and satisfy the applicable load and consumption conditions. Selecting Hasir Alo in the calculator does not independently confirm eligibility.
Example: Eligible Hasir Alo Consumer Using 70 Units Quarterly
Suppose an eligible consumer has a sanctioned load of 0.3 kW or less and uses 70 units during a three-month billing period.
- Quarterly eligibility limit: 75 units
- Actual consumption: 70 units
- Energy-charge benefit: Applied under the supplied configuration
- Fixed charge: ₹0
- Estimated energy amount after subsidy: ₹0
The official bill should be checked for the treatment of statutory or account-specific components.
Domestic Fixed Monthly Charge
The supplied standard WBSEDCL Domestic fixed charge is ₹40 per month.
For a three-month quarterly billing period, the calculator can scale the charge according to the billing duration:
₹40 × 3 months = ₹120
The Hasir Alo category uses a configured fixed charge of ₹0 when all eligibility conditions are satisfied.
Consumers should enter or confirm the billing period carefully so that monthly charges are not incorrectly applied to a quarterly bill.
FPPCA Fuel Surcharge and Electricity Duty
The supplied calculator information includes the following mandatory components:
- FPPCA: ₹0.45 per applicable electricity unit
- Electricity Duty: 6% according to the configured taxable billing components
FPPCA means Fuel and Power Purchase Cost Adjustment. It reflects fuel and power procurement cost variations and is calculated separately from the basic energy tariff.
For example, FPPCA for 220 billed units is:
220 × ₹0.45 = ₹99
The calculator displays FPPCA and Electricity Duty separately so users can understand how these components affect the estimated final bill. The actual FPPCA rate and official duty base may be revised or applied differently on the consumer’s bill.
Supported WBSEDCL Connection Categories
The calculator can support the following categories using the supplied tariff information:
- WBSEDCL Domestic Supply
- Domestic Hasir Alo Scheme
- Non-Domestic Commercial Supply
- EV Charging Station
Each category follows a different energy rate, fixed-charge rule, and subsidy treatment. Consumers should select the connection category printed on their latest WBSEDCL electricity bill.
Commercial and EV Tariff Overview
Under the supplied data, Non-Domestic Commercial consumption is calculated at ₹8.95 per unit. A fixed demand charge of ₹150 per kW per month is added according to sanctioned load.
EV Charging Station consumption is calculated at ₹7.15 per unit with a configured fixed charge of ₹0. Domestic and Hasir Alo subsidies do not apply to commercial or EV categories.

How the Estimated WBSEDCL Bill Is Prepared
The calculator first identifies the selected category, billing duration, total consumption, sanctioned load, and scheme eligibility.
Domestic slab limits are scaled according to the monthly or quarterly billing period. Energy consumption is then distributed telescopically across the applicable slabs.
The calculator adds the fixed charge, FPPCA, and configured Electricity Duty. Eligible Hasir Alo consumers receive the supplied subsidy adjustment after load and consumption conditions are checked.
The result remains an estimate. An official WBSEDCL bill may include arrears, delayed payment surcharge, meter charges, security-deposit adjustments, subsidy corrections, revised FPPCA, penalties, rounding differences, or updated regulatory components.
Why Is Our WBSEDCL Electricity Bill Calculator Different From Other Tools?
A West Bengal electricity bill cannot always be estimated by multiplying total consumption by one standard rate. Domestic consumers follow telescopic tariff slabs, while the applicable consumption limits depend on whether the bill covers one month or a three-month quarterly period.
The calculation may also include a monthly fixed charge, Fuel and Power Purchase Cost Adjustment, Electricity Duty, sanctioned-load-based commercial charges, and the configured Hasir Alo Scheme benefit.
The WBSEDCL Electricity Bill Calculator processes these billing components separately. It scales the tariff limits according to the selected billing cycle, divides domestic consumption across the applicable slabs, checks Hasir Alo eligibility, adds fixed charges and FPPCA, calculates Electricity Duty, and displays an itemized estimate.
| Feature | WBSEDCL Calculator | Basic Calculator |
|---|---|---|
| Billing-Cycle Scaling | Adjusts slab limits for monthly or quarterly bills | May use monthly slabs for every bill |
| Domestic Tariff | Calculates each telescopic slab separately | May multiply all units by one rate |
| Hasir Alo Scheme | Checks load, consumption, and billing-period limits | May apply the benefit without checking eligibility |
| Bill Breakdown | Shows energy, fixed charge, FPPCA, duty, and subsidy | Usually displays only an approximate total |
WBSEDCL Domestic Monthly Tariff Slabs
| Monthly Consumption | Energy Rate | Calculation Treatment |
|---|---|---|
| 0–25 units | ₹5.30/unit | Applied to the first 25 units |
| 26–75 units | ₹5.85/unit | Applied to the next 50 units |
| 76–150 units | ₹6.70/unit | Applied to the next 75 units |
| 151–300 units | ₹7.50/unit | Applied to units within this slab |
| Above 300 units | ₹8.50/unit | Applied only to units exceeding 300 |
Quarterly Tariff Scaling
When the selected billing period is three months, the monthly tariff limits are multiplied by three.
- First quarterly slab: 0–75 units at ₹5.30 per unit
- Second quarterly slab: 76–225 units at ₹5.85 per unit
- Third quarterly slab: 226–450 units at ₹6.70 per unit
- Fourth quarterly slab: 451–900 units at ₹7.50 per unit
- Above 900 units: ₹8.50 per unit
The standard domestic fixed charge also scales from ₹40 per month to ₹120 for a complete three-month billing period.
Example: Monthly Domestic Consumer Using 220 Units
For a one-month bill, the monthly-equivalent slabs apply.
- First 25 units: 25 × ₹5.30 = ₹132.50
- Next 50 units: 50 × ₹5.85 = ₹292.50
- Next 75 units: 75 × ₹6.70 = ₹502.50
- Remaining 70 units: 70 × ₹7.50 = ₹525
- Total energy charge: ₹1,452.50
- Fixed monthly charge: ₹40
- FPPCA: 220 × ₹0.45 = ₹99
- Illustrative duty on energy charge: 6% of ₹1,452.50 = ₹87.15
- Illustrative estimated total: ₹1,678.65
This illustration applies the supplied 6% duty to the energy charge only. The official taxable base should be confirmed from the actual WBSEDCL bill.
Example: Quarterly Domestic Consumer Using 220 Units
The same 220 units produce a different result when they represent a complete three-month billing cycle.
- First 75 units: 75 × ₹5.30 = ₹397.50
- Remaining 145 units: 145 × ₹5.85 = ₹848.25
- Total energy charge: ₹1,245.75
- Quarterly fixed charge: ₹40 × 3 = ₹120
- FPPCA: 220 × ₹0.45 = ₹99
- Illustrative duty: 6% of ₹1,245.75 = ₹74.75
- Illustrative estimated total: ₹1,539.50
This example demonstrates why consumers must select the correct monthly or quarterly billing period.
How the Hasir Alo Scheme Is Calculated
Under the supplied calculator configuration, Hasir Alo applies to an officially eligible low-load domestic consumer when sanctioned load does not exceed 0.3 kW.
- Monthly limit: Up to 25 units
- Quarterly limit: Up to 75 units
- Eligible energy charge: 100% subsidized
- Configured fixed charge: ₹0
- Consumption above the limit: Standard domestic billing applies according to the configured rules
Example: Hasir Alo Consumer Using 70 Units Quarterly
- Sanctioned load: 0.3 kW or less
- Quarterly consumption: 70 units
- Scheme limit: 75 units
- Energy-charge subsidy: Applied under the supplied configuration
- Fixed charge: ₹0
- Estimated energy charge after subsidy: ₹0
The supplied information confirms free energy and a zero fixed charge but does not fully define whether FPPCA, Electricity Duty, arrears, or other account-specific components are waived. The calculator should display their treatment separately.
Non-Domestic Commercial Tariff
The Non-Domestic Commercial category may apply to eligible shops, offices, clinics, hotels, restaurants, showrooms, and other business premises.
- Energy charge: ₹8.95 per unit
- Fixed demand charge: ₹150 per kW per month
- Domestic subsidy: Not applicable
Example: Commercial Consumer Using 400 Units
Suppose a commercial connection uses 400 units in one month with a sanctioned load of 5 kW.
- Energy charge: 400 × ₹8.95 = ₹3,580
- Fixed demand charge: 5 × ₹150 = ₹750
- FPPCA: 400 × ₹0.45 = ₹180
- Illustrative duty on energy: 6% of ₹3,580 = ₹214.80
- Illustrative estimated total: ₹4,724.80
For a multi-month billing period, monthly fixed demand charges should be scaled according to the actual number of billed months.
EV Charging Station Tariff
- Energy charge: ₹7.15 per unit
- Fixed charge: ₹0
- Hasir Alo benefit: Not applicable
An EV charging station using 1,000 units receives a basic energy charge of ₹7,150. The configured FPPCA is ₹450. Electricity Duty and any other applicable regulatory components are calculated separately.
