KSEB Electricity Bill Calculator 2026
To calculate your KSEB electricity bill in Kerala, multiply the units consumed in each progressive tariff slab by the notified unit rate, add monthly fixed capacity charges (₹35/kW), apply state electricity duty (10%) and fuel adjustments (FAC), then deduct applicable government subsidy waivers.
Tariff Structure Note: Kerala State Electricity Board (KSEB) domestic billing under KSERC uses a bi-monthly billing cycle with telescopic slabs up to 250 units/month and non-telescopic flat billing for consumption exceeding 250 units/month (500 units bi-monthly).
Based on published KSERC LT-1A domestic schedule benchmarks. Rates and fuel adjustment surcharges are illustrative; confirm against your active KSEB bi-monthly bill.

How is Electricity Bill Calculated in Kerala?
Electricity bills in Kerala under KSEB follow a hybrid telescopic and non-telescopic tariff structure approved by the KSERC. For households consuming up to 250 units monthly (or 500 units bi-monthly), billing is strictly telescopic: units are divided across progressive brackets from ₹3.25/unit up to ₹8.00/unit. However, when consumption exceeds 250 units in a single month, non-telescopic billing is triggered, meaning higher flat rates apply across the entire consumption volume. In addition to energy charges, KSEB bills include fixed demand charges based on connected phase (single-phase vs three-phase), an electricity duty of 10%, and a fuel adjustment surcharge.
