Smart Energy Optimization
From calculating appliance running wattage (AC, BLDC fans, refrigerators) to estimating PM Surya Ghar rooftop solar ROI, we help citizens save money.
1 Who We Are
InBillCalculator.com was founded by a passionate team of Indian software engineers, energy analysts, and consumer advocates. Understanding monthly electricity utility bills in India has historically been fraught with confusion: varying fixed demand charges per kW, state-specific electricity duty percentages, fuel price surcharges (FPPPA / FAC), and bi-monthly vs. monthly billing cycles.
We developed a centralized, completely free, and open calculation platform so that any homeowner, tenant, small business owner, or student can calculate their expected electricity dues in seconds, verify their meter readings, and audit their actual paper bills against authorized regulatory tariffs.
2 Coverage & Methodology
Our platform covers all major regional utilities across India, including:
- Tamil Nadu: TANGEDCO / TNEB
- Karnataka: BESCOM, MESCOM, HESCOM, GESCOM
- Kerala: KSEB
- Maharashtra: MSEDCL Mahavitaran, Adani, Tata Power
- Uttar Pradesh: UPPCL (DVVNL, MVVNL, PVVNL, PuVVNL)
- Delhi: BSES Rajdhani (BRPL), Yamuna (BYPL), TPDDL
- West Bengal: WBSEDCL, CESC Kolkata
- Punjab: PSPCL
- Gujarat: DGVCL, MGVCL, PGVCL, UGVCL, Torrent Power
- Telangana & Andhra Pradesh: TGSPDCL, TSNPDCL, APEPDCL, APSPDCL
Each state's electricity board utilizes differing computation logic—such as free unit allowances (e.g., Tamil Nadu first 100 units free, Delhi subsidy brackets), varying minimum billing thresholds, and specific electrical duty percentages (e.g. 5% in WB, 16% in Maharashtra, 9 paise/unit in Kerala). Our engine encodes these exact algebraic rules.
