Karnataka Electricity Bill Calculator
Karnataka electricity bill calculator based on published tariff schedules; verify against your bill. Flat ₹5.80/unit + 9% duty and Gruha Jyothi subsidy modeling.
Calculate Your Bill
BESCOM, MESCOM, HESCOM, GESCOM, CESC Mysore • Monthly Cycle
Gruha Jyothi entitlement is your FY23 monthly average + 10% (max 200 units). Leave blank to see your bill without subsidy.
Eligible domestic consumers registered under Karnataka Gruha Jyothi receive up to 200 free units/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. Consumers whose consumption exceeds entitlement pay only for the excess units above their subsidized limit; there is no cliff-edge forfeiture. Rates (₹5.80/unit) and 9% duty are illustrative estimates; confirm with your bill.

How Karnataka (BESCOM) Bills You
Understanding slabs, billing cycles, subsidies, and non-tariff exclusions
Electricity supply and retail tariffs across Karnataka are regulated by the Karnataka Electricity Regulatory Commission (KERC) and distributed through five regional state-owned utilities: BESCOM (Bengaluru electricity supply), MESCOM (Mangaluru), HESCOM (Hubballi), GESCOM (Kalaburagi), and CESC Mysore (Chamundeshwari electricity supply).
Karnataka operates on a standard monthly billing cycle. For domestic residential consumption, this calculator models a flat illustrative rate (benchmarked on this page at an illustrative ₹5.80 per unit for all domestic consumption, which is unconfirmed against active tariff orders and should be verified on your bill), alongside fixed capacity demand charges of approximately ₹150 per kilowatt (kW) of sanctioned load per month.
In addition to base energy and demand fees, domestic bills in Karnataka include statutory add-ons: an estimated 9% Karnataka State Electricity Duty, power purchase adjustment charges, and periodic regulatory true-up recovery surcharges.
A central pillar of residential electricity in Karnataka is the state government's Gruha Jyothi welfare scheme. Under Gruha Jyothi, 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. Eligible households consuming within their entitlement threshold receive a zero-rupee bill. When consumption exceeds the entitlement cap, the consumer pays only for the incremental excess units above the entitlement; the entitlement benefit is not forfeited as an all-or-nothing cliff.
What is NOT included in this standard estimate: This model computes standard domestic tariffs using illustrative baseline estimates. Actual physical utility bills may include past unpaid arrears, Delayed Payment Charges (DPC), meter security adjustments, or non-domestic commercial tariff components.
