Calculate your electricity bill with state-wise DISCOM tariff slabs
Built & maintained by Pappu Venkata Subbi Reddy, founder of Clacify · Formulas verified against official Indian government sources
Clacify's Electricity Bill Calculator covers 13 major Indian states — Karnataka (BESCOM, HESCOM, GESCOM), Maharashtra (MSEDCL, BEST, Adani), Tamil Nadu (TANGEDCO), Telangana (TSSPDCL, TSNPDCL), Andhra Pradesh (APSPDCL, APEPDCL), Delhi (BSES, Tata Power), Gujarat, Kerala (KSEB), Punjab (PSPCL), Rajasthan, Haryana, Uttar Pradesh, and West Bengal. Enter your units consumed and get a complete breakdown: slab-wise energy charges, fuel/PPAC surcharge, electricity duty, fixed meter charge, and applicable government subsidies (Delhi Muft Bijli, Tamil Nadu free units scheme). Rates based on FY 2024-25 tariff orders.
Indian electricity bills use a slab-based (tiered) system where the first X units cost less per unit and usage above that costs more. Your bill = (energy charges by slab) + fixed meter charge + fuel/power purchase adjustment charge + electricity duty/tax − any government subsidy. Use Clacify's Electricity Bill Calculator to see each component separately for your DISCOM.
Common reasons: (1) You crossed a higher tariff slab — in slab systems, using 201 units instead of 200 means ALL units are charged at the higher rate in some states. (2) Fuel surcharge increased quarterly. (3) Air conditioner running longer in summer. (4) Geyser or EV charger added to usage. Use the calculator to find exactly which slab you're in.
Top 5 ways: (1) Set AC to 24°C or higher — each degree lower adds 6% to consumption. (2) Switch to 5-star BEE-rated appliances. (3) Stay within lower slabs — if you're at 195 units, reducing by 5 saves disproportionately. (4) Use LED bulbs. (5) Turn off geysers 15 minutes after use and switch to solar water heaters for maximum savings.
