How to Use the IESCO Bill Calculator 2026

To use the IESCO bill calculator, users must know the units consumed during the billing period. The electric meter keeps a proper record of the current month’s units used. Check the meter reading to know your total units used during the current billing cycle. Once you know the exact units, it becomes easy to calculate the electricity bill by entering the units in the calculator. Follow the steps below to calculate your bill:

Step 1. Enter the Number of Units Consumed

First and foremost, open the calculator given on our website and enter the number of units consumed in a month. If you don’t know your monthly consumed units, check your meter reading. Enter the exact number of units shown in the meter reading. Entering the actual number of units gives an accurate bill estimation.

Step 2. Apply the Tariff Rate and Connection Type

Enter the tariff rate, as the tariff rate determines the cost per unit of electricity. The IESCO calculator uses these tariff rates to estimate electricity charges for the ease of its customers. Tariff rates may also vary on the basis of connection type, so you must choose your exact connection type. Choose from the types mentioned:

• Residential (commonly used)
• Commercial (for your business and shop)
• Industrial (large and small industries)

Step 3. Calculate the Estimated Bill

After entering the required data, review your entered details and compare them with your consumption. Click on the calculate bill button, and your estimated bill will be generated instantly. This bill helps users manage their expenses before the actual due date. This bill will include:

IESCO Bill Calculation Example

The government announced in 2025 the charge rate according to the unit of consumer consumption and tariff rate (based on slab rates). For example, if your consumption this month is 350 units, let’s see how they are priced.

• If they consume 100 units, then their charges are slightly low based on slab rates.
• If they consume 200 units, then their charges are at a slightly higher rate.
• If they consume 300 units, then their charges are the highest.
• After all these prices, taxes and fuel price adjustments are also added.
