How do I calculate my electricity bill?

Multiply units used by the price per unit, then add any fixed and additional charges.

What is one unit of electricity?

One unit is one kilowatt-hour (kWh) — for example, a 1,000-watt appliance running for one hour.

Does this use my state's tariff?

No. Tariffs vary by provider and state, so enter the rates from your provider's bill or tariff.

Is the result my official bill?

No. It's an estimate. Your provider's bill may include slabs, taxes or adjustments not entered here.

This is an estimate, not an official bill. Tariffs, slabs, taxes and charges vary by provider and state — enter the rates shown on your provider's bill or tariff.

Energy charge = units × price per unit; estimated bill = energy charge + fixed charges + additional charges. For example, 250 units at ₹7 is ₹1,750, plus ₹100 fixed and ₹150 other charges gives ₹2,000. Use the rates from your own electricity provider.

What is the Electricity Bill Calculator?

What the tool does, who it is for and what it cannot tell you.

An electricity bill is mostly the units you used (kWh) multiplied by a price per unit, plus fixed charges and other items such as duties or fees.

Rates differ by provider, state and connection type, and many use slabs. This calculator doesn't include any tariff — you enter the rates that apply to you.

Each step the calculator runs, in plain language.

Enter units used
Read the kWh figure from your meter or bill.
2
Enter your price per unit
Use your provider's rate; decimals are fine.
3
Add other charges
Optional fixed and additional charges are added to the total.

A single flat price per unit applies to all units.
Taxes, subsidies and slab rates are not applied unless you include them in the charges you enter.

Financial tips

Practical guidance to act on your result.

To estimate units for an appliance: watts × hours used ÷ 1,000 = kWh.
Compare a few months of bills to see how seasonal use changes the total.
