How is Electricity Bill Calculated in Karnataka?
Electricity billing under BESCOM across Bangalore and Karnataka operates on a monthly billing cycle. For residential billing, this calculator models a flat illustrative rate structure (modeled here at an illustrative ₹5.80/unit, alongside an estimated ₹150/kW monthly fixed charge and 9% electricity duty, which should be verified against your official bill). Under the state's flagship Gruha Jyothi scheme, eligible domestic households receive up to 200 free units per month. Each household's monthly free-unit entitlement is personalized based on past consumption patterns, up to a maximum of 200 units; the exact calculation method should be confirmed with BESCOM or via the Seva Sindhu portal. If household consumption exceeds the entitlement, the consumer pays only for the incremental excess units; the entitlement waiver is retained rather than forfeited. Standard retail bills also itemize a Pension & Gratuity (P&G) surcharge of ₹0.35/unit, an illustrative FY25 True-Up deficit charge of ₹0.56/unit, and state electricity duty.
How to Calculate Your BESCOM (Karnataka) Electricity Bill
Record Monthly Meter Consumption
Read total active kWh units consumed during the 30-day monthly billing cycle.
Evaluate Gruha Jyothi Entitlement
Determine personalized entitlement (up to 200 units/mo based on past consumption patterns; confirm with BESCOM). If current draw is ≤ entitlement, net bill is ₹0.00.
Calculate Partial Subsidy for Excess Units
If consumption exceeds entitlement, the consumer pays only for the excess units above entitlement at standard illustrative rates; the base entitlement remains fully subsidized.
Apply Flat Energy Rate & Fixed Charge
Multiply excess units by the flat rate (modeled at ₹5.80/unit domestic or ₹6.80/unit commercial), plus applicable pro-rata fixed capacity charges (₹150.00/kW/month).
Add Surcharges & State Duty
Add P&G surcharge (₹0.35/u), FY25 True-Up installment (₹0.56/u), and state electricity duty (modeled at 9%) on applicable energy and fixed charges.

Residential Billing Structure (This Calculator Models a Flat Illustrative Rate)
Unlike most Indian states—such as Tamil Nadu (TNEB), Maharashtra (MSEDCL), and Kerala (KSEB)—which continue to compute power bills through tiered progressive brackets, this calculator models a flat illustrative rate structure for low-tension residential billing (LT-1) (benchmarked on this page at an illustrative rate of ₹5.80 per unit for domestic consumption).
Specific per-unit rates cited across secondary sources vary widely (from ₹2.85 to ₹8.16/unit) and remain unconfirmed against primary KERC orders. Always check your actual physical bill for current energy charges.
Gruha Jyothi Entitlement: Personalized Quota vs. Flat 200 Free Units Myth
A widespread public misconception is that Karnataka provides an unconditional grant of 200 free units to every resident. In reality, the Gruha Jyothi scheme uses an individualized entitlement model tied directly to each household meter:
- Personalized Entitlement: Each household's monthly free-unit entitlement is personalized based on past consumption patterns, up to a maximum of 200 units; the exact calculation method should be confirmed with BESCOM or via the Seva Sindhu portal.
- Full Waiver Within Quota: If your monthly consumption stays within your approved personalized entitlement, your net bill is ₹0.
- Partial Billing: If your monthly usage exceeds your entitlement, you are not penalized for previous free units; you pay only for the incremental units above your entitlement.
Pay Only for Excess Units (No Subsidy Cliff Edge)
Unlike subsidy models where exceeding a consumption ceiling disqualifies the entire bill, Gruha Jyothi protects your subsidized entitlement. If a registered household consumes more than their entitlement or crosses 200 units, the consumer does NOT forfeit the full subsidy. Instead, you receive the full benefit for your subsidized entitlement units and pay standard retail rates only for the incremental excess units. For example, using an illustrative entitlement assumption of 90 units, 200 units costs ₹975, while 201 units costs ₹983—a smooth scale with no cliff-edge penalty.
FY25 True-Up Recovery (56 Paise/Unit)
Retail bills may itemize a true-up deficit recovery line item (modeled on this page at an illustrative 56 paise / ₹0.56 per unit). This calculator includes this item as an illustrative charge unless you enter specific bill details. Verify applicability on your bill.
Pension & Gratuity (P&G) Surcharge, Fuel Adjustment Charges (FAC) & 9% Karnataka Electricity Duty
BESCOM retail invoices itemize additional statutory components:
- Pension & Gratuity (P&G) surcharge: An approved regulatory pass-through charge of ₹0.35 per unit dedicated to meeting the terminal pension and gratuity obligations of state power transmission and distribution employees.
- Fuel Adjustment Charges (FAC): Variable quarterly pass-through adjustment determined by KERC based on actual fuel and power purchase costs; shown separately as variable/not included in standard base tariff calculations.
- State Electricity Duty (9%): Governed under the Karnataka Electricity (Taxation on Consumption) Act, 1959, this statutory tax is modeled at an estimated 9% on the sum of base Energy Charges and Fixed Demand Charges (an unconfirmed illustrative estimate; verify with your bill).
Tariff Comparison: Domestic (LT-1) vs Commercial (LT-3)
Operating a home clinic, retail store, or commercial facility in Bangalore? Commercial tariffs under LT-3 incur higher base energy and fixed demand fees, and are not eligible for Gruha Jyothi zero-billing.
| Category | Base Energy Rate | Fixed Demand Fee | Electricity Duty | Gruha Jyothi Subsidy |
|---|---|---|---|---|
| Domestic (LT-1 / LT-2a) | ₹5.80 / unit | ₹150.00 / kW / mo | 9.00% | Eligible (≤200 units) |
| Commercial (LT-3a) | ₹6.80 / unit | ₹215.00 / kW / mo | 9.00% | Not Eligible (Full Bill) |
Commercial rates vary by sub-category and load. Verify against your bill.

Frequently Asked Questions (BESCOM (Karnataka) Bill Calculation)
Common queries answered regarding Karnataka electricity tariffs, slabs, and billing rules.
What is BESCOM per unit rate? ▼
Published reports commonly cite a flat residential energy rate of ₹5.80 per unit alongside a ₹150/kW fixed load charge, a 35 paise P&G surcharge, true-up adjustments, and a 9% state duty. However, reported figures across public sources vary widely and are not verified against official KERC tariff orders. Treat these numbers as an illustrative benchmark and verify exact charges on your official BESCOM bill.
How much will my electricity bill be for 200 units in Bangalore? ▼
If you are enrolled in the Gruha Jyothi scheme and your personalized entitlement covers 200 units, your net payable bill is ₹0. If you are not enrolled or do not qualify for the subsidy, a 200-unit bill on a 2 kW domestic connection costs approximately ₹1,773 based on illustrative rates (₹1,160 energy charge + ₹300 fixed charge + ₹70 P&G surcharge + ₹112 true-up + ₹131.40 duty). Under a 90-unit baseline entitlement, a 200-unit bill with partial subsidy is ₹975.
How is a BESCOM bill calculated? ▼
A BESCOM bill comprises five primary components: Energy Charges (units consumed × flat rate, modeled at ₹5.80), Fixed Demand Charges (sanctioned load in kW × fixed rate), Pension & Gratuity Surcharge (units × ₹0.35), True-Up Deficit Recovery (units × ₹0.56), and State Electricity Duty (estimated at 9%), minus any eligible Gruha Jyothi subsidy.
How much is 300 units of electricity under BESCOM? ▼
For 300 units on a standard 2 kW sanctioned load, the unsubsidized bill is approximately ₹2,497. If you are enrolled in Gruha Jyothi with a 90-unit entitlement, you pay only for the 210 excess units above your entitlement (approximately ₹1,748), retaining your subsidized quota rather than losing it completely.
How much bill for 1 hour AC? ▼
A modern 1.5-ton 5-star inverter AC running at 24°C consumes roughly 0.8 to 1.0 unit per hour. At an illustrative effective tariff of ~₹7.50/unit, running your AC for one hour costs approximately ₹6.00 to ₹7.50. A 3-star non-inverter AC uses 1.4 to 1.6 units per hour, costing ₹10.50 to ₹12.00 per hour.
Why is the BESCOM bill high? ▼
Spikes in BESCOM bills typically happen for several reasons: (1) high seasonal consumption pushing usage well above your historical Gruha Jyothi entitlement, meaning more units are billed at standard rates; (2) true-up deficit recovery adjustments (modeled on this page at 56 paise per unit); (3) average-based billing generated when meter readers skip physical visits; or (4) exceeding your sanctioned load, which incurs Maximum Demand (MD) penalties.
How to apply for 200 units of free electricity in Karnataka? ▼
Visit the official Karnataka Seva Sindhu Portal (sevasindhugs.karnataka.gov.in) under the Gruha Jyothi section. Complete Aadhaar OTP verification, select your ESCOM (BESCOM), enter your 10-digit Account ID / Connection ID from your bill, select your occupancy status (Owner or Tenant), and submit the form to receive an acknowledgment slip.
What do 1000 units of electricity cost under BESCOM? ▼
For 1,000 units on an illustrative domestic connection (e.g. 4 kW load), the bill totals approximately ₹7,886: ₹5,800 energy charges (1,000 × ₹5.80) + ₹600 fixed charges (4 kW × ₹150) + ₹350 P&G surcharge + ₹560 true-up + ₹576 electricity duty (9%). On a commercial LT-3 connection, 1,000 units costs approximately ₹8,791 (for a 2 kW load) to ₹9,494 (for a 5 kW load).
Does Karnataka BESCOM have telescopic electricity slabs? ▼
For residential billing, this calculator models a flat illustrative rate structure for domestic energy consumption (modeled here at ₹5.80/unit), while progressive relief is delivered via the Gruha Jyothi subsidy.
What is the FY25 True-up charge of 56 paise per unit on BESCOM bills? ▼
On actual BESCOM bills, the 56 paise FY25 true-up is charged as 12 fixed monthly instalments based on your FY2024-25 consumption (May 2026 to April 2027). This calculator estimates it from your current units unless you enter your FY2024-25 total.
