Calculating an electricity bill manually can become confusing when telescopic tariff slabs, sanctioned-load-based fixed charges, government subsidy, Electricity Duty, and different consumer categories are calculated separately.
The CSPDCL Electricity Bill Calculator is a smart online utility designed for electricity consumers served by Chhattisgarh State Power Distribution Company Limited. It helps domestic households, commercial establishments, and small industrial consumers estimate their monthly electricity expenses before receiving the official power bill.
Using the supplied Chhattisgarh State Electricity Regulatory Commission FY 2026–27 tariff information, the calculator supports Domestic LV-1 telescopic slabs, the configured Bijli Bill Half Yojana benefit, Small Commercial Non-Domestic LV-2.1 tariffs, Small Power Industrial LV-5 charges, fixed demand charges, and 8% State Electricity Duty.
CSPDCL serves consumers across Chhattisgarh, including Raipur, Bilaspur, Durg, Bhilai, Korba, Rajnandgaon, Jagdalpur, and surrounding urban, rural, commercial, and industrial regions.
Electricity consumption can differ considerably across these locations. A household in Raipur may use electricity for air conditioning, lighting, water pumping, and household appliances, while a shop in Bilaspur, a commercial property in Bhilai, or a small industrial unit in Korba may have higher monthly consumption and sanctioned load.
The calculator simplifies the complete process by showing slab-wise energy charges, fixed demand charges, the Bijli Bill Half subsidy rebate, 8% Electricity Duty, and the estimated net payable amount in a transparent itemized report.
What Is the CSPDCL Electricity Bill Calculator?
The CSPDCL Electricity Bill Calculator is an online electricity bill estimation tool developed for consumers of Chhattisgarh State Power Distribution Company Limited. It calculates an expected monthly bill using electricity consumption, connection category, sanctioned load, and domestic subsidy eligibility.
Unlike a basic calculator that multiplies all consumed units by one general electricity rate, this tool follows the supplied calculation rules for each supported consumer category.
Domestic LV-1 consumers are calculated through telescopic tariff slabs. Under telescopic billing, different portions of monthly electricity consumption are charged at different rates.
The supplied Domestic LV-1 energy rates are:
- 0–100 units: ₹4.10 per unit
- 101–200 units: ₹4.20 per unit
- 201–400 units: ₹5.60 per unit
- 401–600 units: ₹6.60 per unit
- Above 600 units: ₹8.30 per unit
For example, if a domestic consumer uses 220 units, the complete consumption is not charged at ₹5.60 per unit. The calculator divides the consumption into separate tariff brackets:
- The first 100 units are calculated at ₹4.10 per unit.
- The next 100 units are calculated at ₹4.20 per unit.
- The remaining 20 units are calculated at ₹5.60 per unit.
- The applicable fixed charge is added separately.
- The configured Bijli Bill Half rebate and 8% Electricity Duty are then calculated.
This slab-wise calculation provides a more useful estimate than applying the highest applicable tariff rate to every consumed unit.
How the Bijli Bill Half Yojana Works
The calculator can apply the configured Chhattisgarh Government Bijli Bill Half Yojana benefit for eligible domestic consumers.
Under the supplied calculation rule, when total monthly domestic consumption is 400 units or less, the calculator applies a 50% rebate to eligible energy charges and domestic fixed charges.
For example, when an eligible household consumes 220 units, the calculator first calculates the complete slab-wise energy charge and applicable fixed charge. It then displays the 50% subsidy rebate separately before calculating the estimated final payable bill.
If monthly consumption exceeds 400 units, the configured Bijli Bill Half benefit does not apply. The calculator automatically switches to standard domestic tariff calculation without the 50% rebate.
This condition is important because the scheme is not designed as a permanent 50% discount for every consumption level. The total monthly units must remain within the configured 400-unit eligibility limit.
The calculator should show the following components clearly:
- Gross slab-wise energy charge
- Applicable domestic fixed charge
- Bijli Bill Half subsidy rebate
- Amount remaining after subsidy
- Estimated 8% Electricity Duty
- Estimated net payable amount
Supported CSPDCL Connection Categories
The calculator supports the following consumer categories using the supplied tariff information:
- LV-1 Domestic Supply with Bijli Bill Half Yojana
- LV-1 Domestic Supply without subsidy
- LV-2.1 Small Commercial Non-Domestic
- LV-5 Small Power Industrial
- EV Charging after the applicable tariff is configured
Each category follows different energy rates, fixed-charge rules, load requirements, and subsidy conditions. Selecting the category printed on the official electricity bill is essential for obtaining a closer estimate.
An EV Charging option may appear in the calculator interface, but a specific EV energy rate and fixed-charge amount were not included in the supplied data. This category should only be enabled after the applicable tariff has been configured.

How the Estimated CSPDCL Bill Is Prepared
The calculator first identifies the selected consumer category and total monthly electricity consumption. Domestic consumption is distributed across the applicable telescopic slabs.
For an eligible domestic connection using no more than 400 units, the calculator applies the configured 50% rebate to eligible energy and fixed charges. If consumption exceeds 400 units, standard billing applies without the Bijli Bill Half benefit.
Commercial consumers are calculated through the applicable consumption slabs and a fixed demand charge of ₹50 per kW per month. Small Power Industrial consumers are calculated using the supplied flat energy rate and load-based fixed charge.
After calculating energy charges, fixed charges, and subsidy adjustments, the calculator applies the configured 8% Electricity Duty and displays every component separately.
The result remains an estimate. An official CSPDCL bill may include previous arrears, delayed payment surcharge, meter charges, security-deposit adjustments, subsidy corrections, penalties, rounding differences, or updated regulatory charges.
