KE Bill Calculator 2026: Estimate Your K-Electric Bill Online
Want to know your K-Electric bill before it arrives? This KE bill calculator estimates it using the units you enter above. It covers energy charges, fixed charges, FCA, GST, Electricity Duty, and the TV fee. These use the rates currently configured in the tool.
What Is a Unit of Electricity?
A unit of electricity is one kilowatt-hour, also written as kWh. It is the amount of energy used by a 1,000-watt appliance running for one hour. Your K-Electric bill charges you based on how many units, or kWh, you use each month. This number is printed on your bill and also shown on your meter.
How Does the KE Bill Calculator Work?
This calculator has three modes. Basic gives a quick estimate using preset rates. Advanced lets you customize FCA, GST, and other charges yourself. Compare shows your estimated bill across common unit levels side by side. All three use K-Electric’s residential tariff slabs for protected and unprotected consumers.
How to Use the Online KE Bill Calculator
- Check your meter or last bill for your current month’s units. Don’t have your bill handy? Check your KE duplicate bill first to find it.
- Enter that number into the Units field.
- Select Protected or Unprotected as your consumer type.
- Click Calculate to see your estimated bill.
- Review the breakdown to see how each charge adds up. Switch to Advanced mode if you want to adjust the FCA rate, GST, or other charges yourself.
Illustrative Example: How a KE Bill Is Calculated
Here is exactly how the calculator computes a bill for 250 units under Unprotected status, using its current preset rates. The rates and adjustments used by the calculator can change, so this example shows the calculation method rather than a guaranteed bill amount.
| Component | Amount |
|---|---|
| 1 to 100 units at PKR 22/unit | PKR 2,200 |
| 101 to 200 units at PKR 25/unit | PKR 2,500 |
| 201 to 250 units at PKR 26.80/unit | PKR 1,340 |
| Energy subtotal | PKR 6,040 |
| Fixed/meter charge | PKR 75 |
| FCA (PKR 3.23 x 250 units) | PKR 807.50 |
| GST (17%) | PKR 1,176.83 |
| Electricity Duty (1.5%) | PKR 103.84 |
| TV Fee | PKR 35 |
| Estimated total | PKR 8,238 |
This shows why your bill is not just units multiplied by one flat rate. Energy charges alone make up less than 75 percent of the final total once FCA, GST, Electricity Duty, and other charges are added.
Connection Types and How They’re Billed
This calculator currently estimates residential bills only, based on Protected and Unprotected consumer status. Commercial and industrial connections use different tariff structures that this tool does not calculate. Here is how each type differs.
Domestic (residential)
Domestic connections use the slab-based residential tariff this calculator is built on. Most households in Karachi fall under this category. Eligible residential consumers may qualify for protected rates under the applicable rules.
Commercial
Commercial connections use separate tariff categories from residential consumers. The applicable rate can depend on the connection type, sanctioned load, and whether a time-of-use tariff applies. This calculator does not currently estimate commercial bills.
Industrial
Industrial connections use separate tariff categories, with rates and charges that can depend on sanctioned load and whether the connection is billed under a time-of-use structure. This calculator does not currently estimate industrial bills.
Protected vs. Unprotected Consumer Status
Your consumer status affects which rate applies to your units. Protected status is not determined by the current month’s units alone. Under the applicable residential tariff rules, protected status generally depends on maintaining consumption at or below 200 units consistently over the previous six months, along with other applicable conditions. This calculator asks you to select Protected or Unprotected yourself, since it cannot verify your six-month history automatically. If you are not sure which applies to you, check your most recent official bill. For the full explanation, see our dedicated guide on protected consumer status.

Your bill is not just units multiplied by rate. Here is exactly what this calculator adds on top of energy charges, and what it leaves out.

Why Your Actual Bill May Differ From This Estimate
This calculator gives an estimate, not an exact figure. A few things can cause your real bill to differ.
- FCA uses a preset default rate in Basic mode, not the live current NEPRA-notified figure. Switch to Advanced mode to enter today’s actual FCA if you know it.
- Quarterly Tariff Adjustments are not included in this calculator at all.
- The fixed/meter charge is a flat estimate and may not match your actual sanctioned load.
- Meter reading dates can shift which month’s rates apply.
- If you have solar with net billing, this calculator does not account for export credits. See our K-Electric net metering guide instead.
For your exact current bill, always check your official K-Electric duplicate bill rather than relying on an estimate alone.If your actual bill differs significantly and you cannot account for it, that is worth raising. Our K-Electric complaint guide covers what to do next.
