Electricity Bill Calculator India 2026: State-Wise Domestic Tariffs

Quick answer

Choose your state, enter the units on your bill, and the calculator applies that state’s official domestic tariff: slab-by-slab energy charges, the fixed charge, surcharges, electricity duty and any state subsidy. Every line of the bill is shown, so you can match it against your own. Rates last checked 9 November 2026.

States covered

Each state, union territory and city supplier also has its own page with the full slab table and rules.

How the calculator works

• Energy charge: units are billed slab by slab at the rates in the state regulator’s latest tariff order.
• Fixed charge: per kW of sanctioned load, per connection or by phase, as the state sets it.
• Surcharges and duty: monthly fuel adjustment charges change every month, so copy the figure from your latest bill.
• Subsidy: state schemes such as Delhi’s 200-unit waiver, Karnataka’s Gruha Jyothi and Tamil Nadu’s free units are applied when you tick them.
