IESCO Bill Calculator 2026 — Check Your Electricity Bill Estimate Instantly

Waiting for your electricity bill to arrive is now optional. This IESCO Bill Calculator lets you estimate your monthly electricity charges the moment you know your meter reading.

Enter your units consumed, and the tool instantly calculates your estimated bill using IESCO’s official 2026 tariff rates. The result includes a complete breakdown — energy charges, meter rent, government taxes, and all applicable surcharges — so there are no surprises when your actual bill arrives. This tool is especially useful if you want to budget your monthly expenses.

How to Use the IESCO Bill Calculator

The calculator requires just two pieces of information: your units consumed this month and your consumer type. Here is how to use it:

1- Find your units consumed — Look at your current or previous IESCO bill. Find ‘Present Reading’ and subtract ‘Previous Reading’. The result is your units consumed. Example: Present Reading 5842 minus Previous Reading 5592 equals 250 units.
2-Enter the units in the calculator — Type your units consumed in the input field provided above.
3-Click ‘Calculate’ — Your estimated bill appears instantly with a full charge breakdown.
4- Review the result — The output shows each charge separately: energy cost, fixed charges, FPA, surcharges, GST, and the estimated total payable amount.

Tips: Your meter reading is also printed on every IESCO bill under the section labelled “Meter Reading”. The difference between this month and the last month is always the unit consumed.

Benefits of the IESCO Bill Calculator

Here is what you can do with this calculator:

  • Know your bill before it arrives — Check your estimate on the 25th of the month, before the bill is generated.
  • Understand every charge — See exactly how much is energy cost, how much is tax, and how much comes from FPA and other surcharges.
  • Catch billing errors early — If your estimate differs significantly from your printed bill, it may be a meter reading error or a wrong tariff applied.
  • Plan your monthly budget — No more unexpected electricity costs at the end of the month.
  • Manage slab boundaries — See which tariff slab you are in. If you are close to 200, 300, or 400 units, reducing usage slightly can lower your entire bill.
  • Compare different usage levels — Enter different unit amounts to see how much you save by reducing consumption.
