Who We Are
TNEB Bill Calculator (tnebbillcalculator.info) is an independent, non-commercial web utility created to help domestic electricity consumers in Tamil Nadu quickly estimate their bi-monthly electricity bill.
We are not affiliated with TANGEDCO, TNEB, or any government body. This website is built and maintained by an independent developer based in Tamil Nadu who understands the confusion that arises from the telescopic tariff structure used in the state.
What This Tool Does
Instant Calculation
Enter your consumed units and get an estimated bill amount in seconds.
Slab-wise Breakdown
See exactly how much each unit range costs under the telescopic tariff system.
Subsidy Included
The 100-unit free electricity subsidy for domestic consumers is factored in automatically.
Updated Tariffs
Reflects the latest TANGEDCO tariff revision as of July 2024.
Why We Built This
Tamil Nadu’s telescopic electricity tariff can be confusing. A small increase in units consumed – especially crossing the 500-unit mark – can cause a disproportionately large jump in your bill. Many consumers are unaware of how this slab system works.
This calculator was built to bring clarity and transparency to everyday consumers, helping them understand their bills, plan their usage, and avoid bill shock.
Limitations
This tool estimates energy charges only for Domestic (LT–IA) connections. It does not account for:
Fixed charges, meter rent, electricity tax, fuel surcharge adjustment (FSA), arrears, penalties, or any other components that may appear on your official TANGEDCO bill.
