DHBVN Electricity Bill Calculator (Updated)

Calculating an electricity bill manually can become confusing when domestic categories, telescopic consumption slabs, fixed monthly charges, fuel surcharge, Municipal Tax, Electricity Duty, and sanctioned-load-based charges are calculated separately.

The calculation becomes especially important for domestic consumers because DHBVN uses different billing rules for households consuming up to 100 units and those consuming more than 100 units during a monthly billing cycle.

The DHBVN Electricity Bill Calculator is a smart online utility designed for consumers served by Dakshin Haryana Bijli Vitran Nigam. It helps domestic households, commercial establishments, agricultural consumers, and other supported connection categories estimate their monthly electricity expenses before receiving the official bill.

Using the supplied Haryana Electricity Regulatory Commission FY 2026-27 tariff structure, the calculator applies Domestic Category-I and Category-II rates, telescopic slab calculations, Commercial LT charges, agricultural tariffs, fixed demand charges, Fuel Surcharge Adjustment, Municipal Tax, and Electricity Duty.

DHBVN supplies electricity across important areas of Southern Haryana, including Gurugram, Faridabad, Hisar, Rohtak, Rewari, Sirsa, Fatehabad, Jind, Narnaul, Palwal, and surrounding urban and rural regions.

Electricity consumption can differ significantly across these locations. A household in Gurugram may use electricity for air conditioning, water pumping, household appliances, and home-office equipment, while a commercial property in Faridabad, an agricultural connection in Sirsa, or a business in Hisar may have a different consumption and sanctioned-load profile.

The DHBVN Electricity Bill Calculator simplifies the calculation by showing slab-wise energy charges, fixed charges, FSA surcharge, Municipal Tax, Electricity Duty, and the estimated net payable amount in a clear itemized format.

What Is the DHBVN Electricity Bill Calculator?

The DHBVN Electricity Bill Calculator is an online electricity bill estimation tool developed for consumers of Dakshin Haryana Bijli Vitran Nigam. It calculates an expected monthly bill using electricity consumption, selected connection category, and sanctioned or connected load.

Unlike a basic calculator that multiplies all consumed units by one general rate, this tool follows the applicable billing rules for the selected DHBVN connection category.

Domestic consumers are divided into two categories according to monthly electricity consumption:

• Domestic Category-I: Applicable when monthly consumption is up to 100 units.
• Domestic Category-II: Applicable when monthly consumption is more than 100 units.

Under the supplied tariff logic, the calculator automatically determines the applicable domestic category using the entered monthly units.

For example, a domestic consumer using 90 units falls under Domestic Category-I. The calculator divides the consumption into the applicable lower-rate slabs and does not add the supplied fixed monthly charge.

If the same consumer uses 101 units, the connection is calculated under Domestic Category-II. The calculator applies the Category-II telescopic tariff structure to the total monthly consumption and includes the supplied ₹115 fixed monthly charge.

This category-switching logic is important because Domestic Category-I and Domestic Category-II have different tariff slabs and fixed-charge treatment.

The calculator supports the following DHBVN consumer categories:

• Domestic Category-I
• Domestic Category-II
• Non-Domestic Commercial LT
• Agriculture Metered
• EV Charging when the applicable tariff has been configured

The supplied tariff information includes rates for Domestic Category-I, Domestic Category-II, Commercial LT, and Agriculture Metered. An EV charging estimate should only be enabled after the relevant tariff rate and fixed-charge information have been added to the calculator.

This makes the tool useful for homeowners, tenants, landlords, shops, offices, hotels, restaurants, clinics, educational institutions, agricultural consumers, and other electricity users across Southern Haryana.

How to Use the DHBVN Electricity Bill Calculator?

Key Features of This DHBVN Electricity Bill Calculator

This calculator is designed around the supplied HERC FY 2026-27 tariff information and includes the main billing components required for estimating a Southern Haryana electricity bill.

Why Is Our DHBVN Electricity Bill Calculator Different From Other Tools?

Estimating a DHBVN electricity bill requires more than multiplying monthly electricity consumption by one general tariff rate. Domestic consumers are divided into Category-I and Category-II according to monthly consumption, while commercial and agricultural consumers follow separate billing rules.

The most important difference is the automatic domestic category-switching logic. A household consuming up to 100 units is calculated under Domestic Category-I, which has lower tariff slabs and no fixed monthly charge under the supplied tariff data.

When monthly consumption exceeds 100 units, the complete domestic calculation moves to Category-II. The calculator then applies the Category-II telescopic slabs and adds the supplied fixed monthly charge of ₹115.

The DHBVN Electricity Bill Calculator also calculates Fuel Surcharge Adjustment, Municipal Tax, and Electricity Duty separately. This helps consumers understand how much of the final estimated bill comes from basic energy charges and how much comes from additional statutory components.

Whether you are estimating a household bill in Gurugram, a shop bill in Faridabad, an agricultural connection in Sirsa, or a commercial electricity expense in Hisar, the calculator applies the selected category and relevant tariff rules instead of using one common Southern Haryana electricity rate.

DHBVN Southern Haryana FY 2026-27 Tariff Rates and Categories

The tariff applicable to a DHBVN consumer depends on the connection category, monthly electricity consumption, and sanctioned load.

Domestic Category-I and Category-II consumers follow different tariff slabs and fixed-charge rules. Commercial LT consumers use a flat energy rate with a per-kW fixed demand charge, while eligible metered agricultural connections use a separate subsidized rate.

The following details are based on the supplied HERC FY 2026-27 tariff information used by this calculator.

Domestic Category-I Tariff for Consumption Up to 100 Units

Domestic Category-I applies when total monthly electricity consumption does not exceed 100 units under the supplied tariff structure.

This category uses two telescopic slabs and does not include a monthly fixed charge.

How the Domestic Category-I Calculation Works

Suppose a domestic consumer uses 90 electricity units during one month. The calculator divides the units into two tariff slabs.

• First 50 units: 50 × ₹2.00
• Remaining 40 units: 40 × ₹2.50
• Fixed monthly charge: ₹0
• FSA surcharge: 90 × ₹0.45
• Municipal Tax: 90 × ₹0.05
• Electricity Duty: 90 × ₹0.10

Example: Domestic Category-I Consumer Using 90 Units

• First slab charge: 50 × ₹2.00 = ₹100
• Second slab charge: 40 × ₹2.50 = ₹100
• Total energy charge: ₹200
• Fixed monthly charge: ₹0
• FSA surcharge: 90 × ₹0.45 = ₹40.50
• Municipal Tax: 90 × ₹0.05 = ₹4.50
• Electricity Duty: 90 × ₹0.10 = ₹9
• Estimated total: ₹254

The calculator shows each component separately so the consumer can distinguish the basic electricity cost from the additional per-unit charges.

Automatic Switching From Domestic Category-I to Category-II

The calculator checks the total monthly electricity units before applying the domestic tariff.

• Consumption up to 100 units: Domestic Category-I rates are applied.
• Consumption above 100 units: Domestic Category-II rates are applied to the monthly consumption according to the supplied category rule.

This means a consumer using exactly 100 units remains in Domestic Category-I, while a consumer using 101 units is calculated under Domestic Category-II.

The category change is important because Category-II has higher energy rates and includes a fixed monthly charge of ₹115.

Why 101 Units Can Produce a Noticeably Higher Bill

When monthly consumption changes from 100 units to 101 units, the calculator does not simply charge the additional one unit at a higher rate. Under the supplied category logic, consumption above 100 units moves the domestic connection into Category-II.

The Category-II tariff structure and fixed monthly charge are therefore used for the calculation. Consumers should monitor their monthly meter readings when electricity usage approaches the 100-unit category limit.

Domestic Category-II Telescopic Tariff

Domestic Category-II applies when monthly electricity consumption exceeds 100 units under the supplied tariff information.

This category uses four telescopic consumption slabs and includes a fixed monthly charge of ₹115.

How the Category-II Telescopic Calculation Works

Suppose a Domestic Category-II consumer uses 220 units during one billing month. The complete consumption is not charged at ₹5.25 per unit.

The calculator divides the monthly units into the applicable slabs:

• First 150 units: Calculated at ₹4.50 per unit
• Remaining 70 units: Calculated at ₹5.25 per unit
• Fixed monthly charge: ₹115
• FSA surcharge: Calculated at ₹0.45 per consumed unit
• Municipal Tax: Calculated at ₹0.05 per consumed unit
• Electricity Duty: Calculated at ₹0.10 per consumed unit

Example: Domestic Category-II Consumer Using 220 Units

• First slab charge: 150 × ₹4.50 = ₹675
• Second slab charge: 70 × ₹5.25 = ₹367.50
• Total energy charge: ₹1,042.50
• Fixed monthly charge: ₹115
• FSA surcharge: 220 × ₹0.45 = ₹99
• Municipal Tax: 220 × ₹0.05 = ₹11
• Electricity Duty: 220 × ₹0.10 = ₹22
• Estimated total: ₹1,289.50

Example: Domestic Category-II Consumer Using 520 Units

A domestic consumer using 520 units enters all four supplied Category-II tariff slabs.

• First 150 units: 150 × ₹4.50 = ₹675
• Next 100 units: 100 × ₹5.25 = ₹525
• Next 250 units: 250 × ₹6.30 = ₹1,575
• Remaining 20 units: 20 × ₹7.10 = ₹142
• Total energy charge: ₹2,917
• Fixed monthly charge: ₹115
• FSA surcharge: 520 × ₹0.45 = ₹234
• Municipal Tax: 520 × ₹0.05 = ₹26
• Electricity Duty: 520 × ₹0.10 = ₹52
• Estimated total: ₹3,344

Non-Domestic Commercial LT Tariff

The Non-Domestic Commercial LT category generally applies to shops, offices, restaurants, hotels, clinics, institutions, business premises, and other eligible commercial connections with a sanctioned load up to 20 kW under the supplied category information.

Example: Commercial Connection With 3 kW Load

Suppose a Commercial LT consumer uses 300 electricity units and has a sanctioned load of 3 kW.

• Energy charge: 300 × ₹6.90 = ₹2,070
• Fixed demand charge: 3 × ₹110 = ₹330
• FSA surcharge: 300 × ₹0.45 = ₹135
• Municipal Tax: 300 × ₹0.05 = ₹15
• Electricity Duty: 300 × ₹0.10 = ₹30
• Estimated total: ₹2,580

Entering the correct sanctioned load is important because the commercial fixed demand charge is calculated on a per-kW basis.

Agriculture Metered Tariff

The Agriculture Metered category applies to eligible agricultural electricity connections operating under the supplied DHBVN tariff data.

The supplied agriculture tariff is highly subsidized compared with domestic and commercial rates. The calculator calculates the basic agricultural energy charge according to monthly metered consumption.

Example: Agriculture Consumer Using 500 Units

• Energy charge: 500 × ₹0.10 = ₹50
• Fixed charge: ₹0
• FSA surcharge: 500 × ₹0.45 = ₹225
• Municipal Tax: 500 × ₹0.05 = ₹25
• Electricity Duty: 500 × ₹0.10 = ₹50
• Estimated total: ₹350

The actual applicability of individual taxes and surcharges to a particular agricultural connection should be checked against the official DHBVN bill and applicable category rules.

EV Charging Category

The calculator interface may include an EV Charging category. However, a specific EV charging energy rate and fixed-charge amount were not included in the supplied DHBVN tariff information.

The EV Charging option should only be activated after the applicable official tariff values have been configured in the calculator.

Until those values are added, EV charging operators should check the tariff category and rates printed on their official electricity bill.

Fuel Surcharge Adjustment Applied to DHBVN Bills

The supplied tariff data includes Fuel Surcharge Adjustment at ₹0.45 per consumed unit. The surcharge is linked directly to monthly electricity consumption.

Municipal Tax Applied to DHBVN Bills

The supplied Municipal Tax is ₹0.05 for every consumed unit. The calculator displays this amount separately from the basic energy charge and Fuel Surcharge Adjustment.

Electricity Duty Applied to DHBVN Bills

The supplied DHBVN calculation data includes Electricity Duty at ₹0.10 for every consumed unit.

How the Estimated DHBVN Electricity Bill Is Calculated

The DHBVN Electricity Bill Calculator prepares the estimated monthly bill through the following process:

1. Select the correct electricity connection category.
2. Enter monthly electricity consumption in kWh.
3. Enter the sanctioned load in kW or HP when required.
4. Check whether a domestic consumer falls under Category-I or Category-II.
5. Apply the applicable domestic telescopic tariff slabs.
6. Apply the commercial or agricultural energy rate when those categories are selected.
7. Add the applicable flat monthly or load-based fixed charge.
8. Calculate FSA at ₹0.45 per consumed unit.
9. Calculate Municipal Tax at ₹0.05 per consumed unit.
10. Calculate Electricity Duty at ₹0.10 per consumed unit.
11. Add all applicable components to display the estimated net payable amount.

The official DHBVN bill may include additional items such as previous arrears, delayed payment surcharge, meter charges, security deposit adjustments, penalties, regulatory revisions, rounding differences, or other consumer-specific amounts.

Why Selecting the Correct Domestic Category Is Important

Domestic Category-I and Category-II use completely different tariff structures under the supplied calculation data.

• Category-I: Applies up to 100 monthly units and includes no fixed monthly charge.
• Category-II: Applies when monthly consumption exceeds 100 units and includes a ₹115 fixed monthly charge.

Selecting Category-I for consumption above 100 units can produce an incorrect estimate. The calculator therefore checks monthly consumption automatically before preparing the domestic bill.

Why Entering the Correct Sanctioned Load Is Important

The sanctioned load directly affects the fixed demand charge for Commercial LT consumers.

For example, a commercial connection with a sanctioned load of 2 kW receives a fixed demand charge of 2 × ₹110, while a 5 kW connection receives a fixed demand charge of 5 × ₹110.

Consumers should enter the sanctioned load printed on their latest DHBVN bill or electricity connection document instead of estimating it from the number of appliances or machines installed at the premises.

Electricity-Saving Tips for DHBVN Consumers

• Monitor the 100-unit category limit: Domestic consumers should track their usage carefully when consumption approaches 100 units.
• Check meter readings regularly: Monthly monitoring can help identify sudden increases or possible meter-reading errors.
• Use energy-efficient air conditioners: Cooling appliances can contribute significantly to household bills in Haryana’s hot summer months.
• Keep AC filters clean: Clean filters and appropriate temperature settings can improve cooling efficiency.
