How to Use the GEPCO Bill Calculator
You only need two numbers from an old bill: the units you used and your sanctioned load. After that, the GEPCO bill calculator updates the total as you type.
Where to find your units and sanctioned load
Both figures sit in the top half of every GEPCO bill. If you are planning ahead, read your meter instead and subtract last month’s reading.
| What you need | Where it appears on the bill | Example |
|---|---|---|
| Units consumed | “Units” box next to the previous and present readings | 300 |
| Sanctioned load | “Load” in the consumer details section | 2 kW |
| Consumer type | 12-month history: 200 units or less in each of the last six months usually means protected | Unprotected |
| Meter reading | Present reading minus previous reading (times MF, if it is more than 1) | 14,520 − 14,220 = 300 |
How the GEPCO Bill Calculator Works Out Your Bill
The calculator follows the same order as a real GEPCO bill. First it prices your units, then it adds the fixed charge and the monthly adjustments, and finally it applies tax.
- Energy charges: units × the NEPRA rate for your slab. Unprotected homes pay one rate on every unit; protected homes get the lower first-slab rate on their first 100 units.
- Fixed charges: your sanctioned load in kW × the fixed rate for your slab. Lifeline homes pay no fixed charge.
- FPA and QTA: units × the fuel price adjustment and the quarterly tariff adjustment that NEPRA set for this month.
- F.C. surcharge: units × Rs 3.23 for unprotected homes or Rs 0.43 for protected homes. Lifeline homes do not pay it.
- GST: 18% of all the charges above.
Because the fixed charge depends on your load, two homes with the same units can still pay different bills. So always enter the load printed on your own bill.
Worked example: 300 units, unprotected, 2 kW
| Charge | How it is worked out | Amount (Rs) |
|---|---|---|
| Energy charges | 300 units × Rs 33.10 (201–300 slab) | 9,930.00 |
| Fixed charges | 2 kW × Rs 350 | 700.00 |
| FPA | 300 × Rs 2.0581 | 617.43 |
| QTA | 300 × Rs 0.5194 | 155.82 |
| F.C. surcharge | 300 × Rs 3.23 | 969.00 |
| GST 18% | 18% of Rs 12,372.25 | 2,227.01 |
| Estimated total | Payable within the due date | 14,599 |
That works out to about Rs 48.66 per unit, all-in. In other words, a unit really costs far more than the Rs 33.10 slab rate. The fixed charge, adjustments, surcharge and tax make up the gap.
Worked example: 150 units, protected, 1 kW
A protected home pays the first 100 units at Rs 10.54 and the next 50 at Rs 13.01, so energy charges come to Rs 1,704.50. Next come a fixed charge of Rs 300, FPA of Rs 308.72, QTA of Rs 77.91 and an F.C. surcharge of Rs 64.50. With GST of Rs 442.01, the estimate is about Rs 2,898.
Typical Bills From the GEPCO Bill Calculator
Want a quick answer without typing anything? Here is what the GEPCO bill calculator shows for common monthly usage with September 2026 rates and adjustments.
| Monthly units | Consumer type and load | Estimated bill (Rs) | All-in cost per unit (Rs) |
|---|---|---|---|
| 80 | Lifeline, no fixed charge | 731 | 9.13 |
| 100 | Protected, 1 kW | 1,835 | 18.35 |
| 200 | Protected, 1 kW | 3,843 | 19.21 |
| 100 | Unprotected, 1 kW | 3,658 | 36.58 |
| 200 | Unprotected, 1 kW | 8,547 | 42.74 |
| 300 | Unprotected, 2 kW | 14,599 | 48.66 |
| 400 | Unprotected, 3 kW | 21,366 | 53.42 |
| 500 | Unprotected, 4 kW | 28,767 | 57.53 |
These are estimates within the due date, before arrears and any income tax. Your own figure will differ if your load or consumer type is different, so run the calculator above with your numbers.
GEPCO Slab Rates Used in This Calculator
All DISCOs, including GEPCO, charge the uniform domestic tariff notified by the federal government on NEPRA’s determination. The calculator uses the rates below for unprotected homes, which cover most GEPCO households.
| Units per month | Rate (Rs per unit) | Fixed charge (Rs per kW per month) |
|---|---|---|
| 1–100 | 22.44 | 275 |
| 101–200 | 28.91 | 300 |
| 201–300 | 33.10 | 350 |
| 301–400 | 36.46 | 400 |
| 401–500 | 38.95 | 500 |
| 501–600 | 40.22 | 675 |
| 601–700 | 41.85 | 675 |
| Above 700 | 47.20 | 675 |
Protected homes pay Rs 10.54 for 1–100 units and Rs 13.01 for 101–200 units, while lifeline homes pay Rs 3.95 or Rs 7.74. For every table, including adjustments and the change history, see the GEPCO unit price page.
Sources: NEPRA tariff notifications and the federal government’s S.R.O. 279(I)/2026 of 12 February 2026, which also introduced per-kW fixed charges for domestic users.
Protected, Unprotected or Lifeline: Which One Are You?
Your consumer type changes the rate on every unit, so choosing the right one matters more than any other setting in the GEPCO bill calculator.
| Type | Who qualifies | How units are priced | Fixed charge |
|---|---|---|---|
| Lifeline | Up to 100 units a month over the last 12 months, with a very small sanctioned load | Lifeline rate on all units; no FPA or QTA | None |
| Protected | 200 units or less in each of the last six months (non-ToU homes) | First 100 units at slab 1, the rest at slab 2 | Yes, per kW |
| Unprotected | Everyone else, including anyone who crossed 200 units in the last six months | Every unit at the rate of the slab your total falls in | Yes, per kW |
If you are not sure, check the units column in your bill’s 12-month history. When any of the last six months shows more than 200 units, choose Unprotected.
Slab Jumps: Why One Extra Unit Can Cost Thousands
Unprotected bills do not rise smoothly. Once your total crosses a slab limit, the higher rate applies to every unit, not just the extra ones, and the fixed charge often rises too.
| Scenario (1 kW load) | Estimated bill (Rs) | What changed |
|---|---|---|
| 200 units, protected | 3,843 | Protected rates on all units |
| 200 units, unprotected | 8,547 | Rs 28.91 on every unit |
| 201 units, unprotected | 9,641 | Rs 33.10 on every unit and a higher fixed charge |
For a protected home, the 201st unit is the most expensive one of the year. Crossing 200 units raises that month’s bill from about Rs 3,843 to about Rs 9,641. In addition, the home loses protected status for the next six months.
What the GEPCO Bill Calculator Leaves Out
The estimate covers the charges that every domestic bill carries. However, a few items depend on your account or tax status, so they are not included.
- Arrears and late payment surcharge. Unpaid amounts from earlier months, plus the surcharge added after the due date.
- Income tax for non-filers. Under the FBR withholding card for 2026–27, domestic users not on the Active Taxpayers List pay 7.5% when the monthly bill is Rs 25,000 or more.
- Commercial taxes. Further tax, extra tax and retailer sales tax apply to some commercial connections, not to ordinary homes.
- Meter rent and other small lines. A few bills show meter rent or service rent. Check your own bill for these.
- Installments, deferred amounts and relief packages. These appear only when GEPCO or the government applies them to your account.
- ToU meters. Homes with a sanctioned load of 5 kW or more are usually billed on peak and off-peak rates, so a flat estimate is only a rough guide.
Electricity duty and the PTV fee no longer appear on domestic bills, so the calculator correctly leaves them out. To understand each line on your printed bill, read how to read a GEPCO bill.
Simple Ways to Lower Your GEPCO Bill
Once you see where the money goes, small changes add up quickly. These habits help most homes in Punjab’s summer months.
- Keep a protected home under 200 units every month, especially from May to September
- Set inverter air conditioners to 26°C and use the sleep timer at night
- Switch to LED lights and inverter or DC ceiling fans
- Turn off water pumps, geysers and chargers when they are not needed
- Read your meter a week before the reading date so you can slow down in time
Also check that your sanctioned load is not higher than you need, since the fixed charge rises with every kW. If it is too high, ask your sub-division office about reducing it.
Frequently Asked Questions About the GEPCO Bill Calculator
How accurate is the GEPCO bill calculator?
For a domestic home with the right units, load and consumer type, the estimate should come close to the current-bill amount on your printed bill. Differences come from arrears, income tax, rounding, or a new FPA that NEPRA announced after we last updated the rates.
How do I calculate my GEPCO bill by hand?
Multiply your units by your slab rate, then add your load in kW times the fixed charge. Next, add units times the FPA, QTA and F.C. surcharge, and finally add 18% GST on the total. The worked example on this page shows each step.
What is the GEPCO bill for 200 units?
With September 2026 rates and a 1 kW load, a protected home pays about Rs 3,843 and an unprotected home about Rs 8,547. Your exact figure depends on your load and this month’s adjustments.
What is the GEPCO bill for 300 units?
An unprotected home with a 2 kW load pays about Rs 14,599 for 300 units, or roughly Rs 48.66 per unit. At 301 units the rate for every unit rises to Rs 36.46, so staying at 300 or below saves money.
Why does the GEPCO bill calculator ask for my sanctioned load?
Since February 2026, most domestic bills include a fixed charge for each kW of sanctioned load. A 3 kW home pays three times the fixed charge of a 1 kW home, even if both use the same units.
What are FPA and QTA in the calculator?
FPA is the fuel price adjustment that NEPRA sets almost every month. QTA is the quarterly tariff adjustment. Both are charged per unit and can be a relief or an extra charge, and lifeline homes are exempt from both.
What is the F.C. surcharge in the GEPCO bill calculator?
It is the debt service surcharge the government adds to each unit to repay loans taken to clear the power sector’s circular debt. On GEPCO bills it is Rs 3.23 per unit for unprotected homes and Rs 0.43 for protected homes. Lifeline homes pay none.
Does the calculator work for commercial or three-phase connections?
It is built for domestic A-1 connections below 5 kW. Commercial, industrial and ToU meters use different rates and peak hours, so use it only as a rough guide for those.
How often are the rates updated?
We check NEPRA decisions every billing cycle. The FPA usually changes every month and the QTA every quarter. Base slab rates now change each January, unless the government notifies a change sooner. The date above the calculator shows when we last verified them.
Why is my real bill higher than the estimate?
Check for arrears, a late payment surcharge, income tax for non-filers, or an installment added to the bill. Also confirm that your consumer type is correct. If the units themselves look wrong, see our GEPCO complaint guide.
Is this an official GEPCO bill calculator?
No. GEPCOBill.com is independent and not affiliated with GEPCO, PITC or NEPRA. We build the estimate from public NEPRA notifications, and your printed bill is always final.
Estimate Today, Check Your Bill Tomorrow
Use the GEPCO bill calculator whenever your meter is close to a slab limit or when NEPRA announces a new adjustment. That way, the bill never comes as a surprise.
Then, when the new bill is issued, open it with the GEPCO online bill check, compare it with your estimate, and pay before the due date.
