How to Calculate Your NEA Electricity Bill: A Step-by-Step Guide

Electricity bills can sometimes be confusing, especially with the different load types and consumption slabs. Whether you're using a single-phase or three-phase system, understanding how your bill is calculated can help you manage your electricity consumption better.

In this article, we will guide you on how to calculate your electricity bill with the Nepal Electricity Authority (NEA) rates, so you can have a clear idea of what to expect when the bill arrives.

Step 1: Identify Your Load Type

The first step in calculating your NEA electricity bill is to identify your load type. NEA has different billing rates for single-phase and three-phase connections. The load types are:

Single-phase: 5A, 15A, 30A, 60A

Three-phase:

• Lower Voltage (up to 10 KVA)
• Middle Voltage (above 10 KVA)

Once you’ve identified your load type, you can move on to calculating your bill based on the units consumed.

Step 2: Understand the Fee Slabs for Single-Phase Connections

For single-phase connections (5A, 15A, 30A, 60A), the electricity charge depends on the units consumed and is divided into different fee slabs. Let’s look at the rates for each load type.

For 5A Load:

• Up to 20 units: Rs. 30 (Minimum Fee)
• 21-30 units: Rs. 50 (Minimum Fee), Rs. 6.50/unit
• 31-50 units: Rs. 50 (Minimum Fee), Rs. 8/unit
• 51-100 units: Rs. 75 (Minimum Fee), Rs. 9.50/unit
• 101-250 units: Rs. 100 (Minimum Fee), Rs. 9.50/unit
• Above 250 units: Rs. 150 (Minimum Fee), Rs. 11/unit

Note:- For consuming 20 or below 20 unit(for 5A only), Electricity fee : Rs 30 only . For Consuming above 20 unit, per unit fee is Rs 3 for 1 to 20 unit .

For 15A Load:

• Up to 20 units: Rs. 50 (Minimum Fee), Rs. 4/unit
• 21-30 units: Rs. 75 (Minimum Fee), Rs. 6.50/unit
• 31-50 units: Rs. 75 (Minimum Fee), Rs. 8/unit
• 51-100 units: Rs. 100 (Minimum Fee), Rs. 9.50/unit
• 101-250 units: Rs. 125 (Minimum Fee), Rs. 9.50/unit
• Above 250 units: Rs. 175 (Minimum Fee), Rs. 11/unit

For 30A Load:

• Up to 20 units: Rs. 75 (Minimum Fee), Rs. 5/unit
• 21-30 units: Rs. 100 (Minimum Fee), Rs. 6.50/unit
• 31-50 units: Rs. 100 (Minimum Fee), Rs. 8/unit
• 51-100 units: Rs. 125 (Minimum Fee), Rs. 9.50/unit
• 101-250 units: Rs. 150 (Minimum Fee), Rs. 9.50/unit
• Above 250 units: Rs. 200 (Minimum Fee), Rs. 11/unit

For 60A Load:

• Up to 20 units: Rs. 125 (Minimum Fee), Rs. 6/unit
• 21-30 units: Rs. 125 (Minimum Fee), Rs. 6.50/unit
• 31-50 units: Rs. 125 (Minimum Fee), Rs. 8/unit
• 51-100 units: Rs. 150 (Minimum Fee), Rs. 9.50/unit
• 101-250 units: Rs. 200 (Minimum Fee), Rs. 9.50/unit
• Above 250 units: Rs. 250 (Minimum Fee), Rs. 11/unit

Step 3: Understand the Fee Slabs for Three-Phase Connections

For three-phase connections, there are different rates depending on the voltage type and KVA (Kilo Volt Ampere). There are two main types:

1.Lower Voltage (400V):

Up to 10 KVA:

• Monthly Minimum Fee: Rs. 1100
• Per Unit Fee (Ashadh to Kartik): Rs. 10.50
• Per Unit Fee (Mangsir to Jestha): Rs. 11.50

Above 10 KVA:

• Monthly Minimum Fee: Rs. 1800
• Per Unit Fee (Ashadh to Kartik): Rs. 10.50
• Per Unit Fee (Mangsir to Jestha): Rs. 11.50

2.Middle Voltage (33/11kV):

• Monthly Minimum Fee: Rs. 10000
• Per Unit Fee (Ashadh to Kartik): Rs. 10.50
• Per Unit Fee (Mangsir to Jestha): Rs. 11.00

Step 4: Calculating the Bill for Single-Phase Connections

To calculate the electricity bill for single-phase connections, follow these steps:

1. Identify your load type (e.g., 5A, 15A, etc.).
2. Check how many units you've consumed.
3. Find the correct fee slab for your load type and consumption range.
4. Apply the minimum fee for your slab and calculate the cost of the additional units at the per-unit rate.

General Formula:The general formula for 5A (when consumption is above 20 units) is:

Total Electricity Bill = Minimum Fee for Range + (Units from 0 to 20 × Per Unit Fee for 0 to 20) + (Units from 21 to 30 × Per Unit Fee for 21 to 30) + (Units from 31 to 50 × Per Unit Fee for 31 to 50) + (Units from 51 to 100 × Per Unit Fee for 51 to 100) + (Remaining Units from 101+ × Per Unit Fee for 101+)

Example: If you have a 5A load and you consumed 50 units, your bill will be calculated as:

• First 20 units: Rs. 30 (Minimum Fee)
• Next 10 units (21-30 units): Rs. 6.50/unit = 10 × 6.50 = Rs. 65
• Remaining 20 units (31-50 units): Rs. 8/unit = 20 × 8 = Rs. 160

Total Bill = Rs. 30 + Rs. 65 + Rs. 160 = Rs. 255

Step 5: Calculating the Bill for Three-Phase Connections

For three-phase connections, follow these steps:

• Identify your voltage type (Lower Voltage or Middle Voltage) and KVA.
• Check how many units you have consumed.
• Apply the minimum monthly fee and multiply the units consumed by the per-unit rate for the respective months.

General Formula

Total Electricity Bill = Minimum Monthly fee + ( per unit fee for range * consumed unit in this range 

Example: If you have a Lower Voltage connection with up to 10 KVA and consumed 20 units, and it is Ashadh to Kartik, the calculation will be:

• Minimum Fee: Rs. 1100
• Per Unit Fee: Rs. 10.50/unit = 20 × 10.50 = Rs. 210

Total Bill = Rs. 1100 + Rs. 210 = Rs. 1310

Step 6: Review Your Bill and Manage Your Consumption

Once you’ve calculated your bill, you can better manage your electricity consumption by identifying which ranges cost more. For instance, using more electricity during the higher per-unit fee range will increase your bill. Being mindful of your usage can help reduce costs.

Conclusion:

Calculating your NEA electricity bill is not as complicated as it may seem. By understanding your load type, identifying the consumption slab, and applying the rates based on your load type, you can calculate your electricity bill accurately. This knowledge helps in controlling consumption and avoiding unnecessary expenses.
