How We Prepare Tariff Data
We compile rates, slabs and subsidy rules from published regulatory and utility sources and from public announcements, with help from AI tools. We then build and test the calculation logic. Pages for states where we have not confirmed the figures against the original order are marked as estimates. We update pages when a published schedule changes or a reader reports a discrepancy that we can confirm.
Who We Are
ElectricityBillCalc.com is an independent project run from India. It is not run by a utility, a regulator, or a team of electrical engineers. The site is built by an independent developer, who has a PGDM in IT and a software and data background. We built these calculators because electricity bills are hard to understand and published tariff documents are written for specialists, not households.
How the Calculators Are Built
- Sources: We collect tariff information from regulator and utility websites, published tariff schedules, government announcements and news reports. We use AI tools to help gather and organise this information.
- Modelling: We turn slabs, fixed charges, duties and subsidy rules into calculator logic, and test the arithmetic with sample cases.
- Limits: We have not yet checked every state's figures against the full official tariff order. Where a rate is illustrative or unconfirmed, the page says so. Fuel surcharges change often, so we use baseline figures.
- Estimates only: Results are estimates, not official bills. Always confirm against your bill or your utility.
Corrections
If you find an error, email support@electricitybillcalc.com with the state, the units you entered and the figure on your bill. We aim to reply within 3–5 working days and correct confirmed errors.
