Estimates, not official bills
Every figure produced by BijliCalculator — slab energy charges, fixed charges, FAC, duty, subsidy-adjusted totals — is an estimate. It is not a bill, an invoice, a demand notice, or an official statement from any electricity utility. Only the DISCOM's own billing system can produce your real bill, and where they differ, the DISCOM's bill prevails.
How we verify tariff data
Slab rates, fixed charges and subsidy rules are entered from published state regulator (SERC) tariff orders and DISCOM tariff schedules wherever we could obtain and verify them. The tariff directory links each state to its regulator and official source so you can check any number yourself. Data carries the tariff year it reflects; a new order mid-year can change rates we have not yet incorporated.
Where real bills differ from estimates
Even with perfect tariff data, a real bill can diverge from an estimate. The usual reasons:
- FAC varies monthly. The fuel adjustment charge is recalculated every billing cycle from the DISCOM's actual fuel costs; our figures are the latest published values.
- Arrears and catch-ups. Settlements of earlier estimated readings, back-billing, or adjustments appear on real bills and are invisible to a calculator that sees only this month's units.
- Category and load specifics. Demand charges, power-factor penalties, meter rent and category-specific exemptions apply to some consumers and not others.
- Subsidy mechanics. Schemes differ in whether the subsidy is credited to the bill or to the DISCOM, and whether it is capped at a fixed amount.
Not advice
Nothing on this site is financial, legal, or regulatory advice. We are not affiliated with any DISCOM, SERC, the CEA, the Ministry of Power, or any government body. Before making decisions that carry money or penalties — disputing a bill, withholding a payment, changing a sanctioned load, buying solar — verify the position with your DISCOM or state regulator, and read the governing tariff order or supply code.
