💡 Electricity Bill

Estimate your monthly electricity bill before it arrives. Enter the units you used — every slab rate can be edited, so you can type in the latest rates of your own company (LESCO, IESCO, K-Electric and others) for the closest estimate.

How to use the Electricity Bill

Enter the units used this month (the difference between meter readings).
Check the slab rates — common recent rates are pre-filled and can be replaced with the rates printed on your own bill.
Optionally add GST and other charges (such as FPA), then press Calculate.

Example: For 300 units with the pre-filled rates, the energy cost is Rs 8,697 and, with GST (18%) added, the bill comes to about Rs 10,262 (the actual bill depends on your company's latest rates).

Frequently Asked Questions

Why is my real bill different?

Rates change with government notifications, fuel price adjustments (FPA) and your consumer category (protected/unprotected). Enter the rates printed on your own bill for the closest estimate.

What is a slab?

Electricity is charged in blocks: the first 100 units at one rate, the next 100 at a higher rate, and so on. This calculator applies each slab correctly.

Does it include FPA and fixed charges?

Add them in the Other charges field — they appear on your bill and vary every month.
