Gas Tariff & Slab Rates 2026
The Oil and Gas Regulatory Authority (OGRA) determines the gas tariff in Pakistan. Prices are split into Protected and Non-Protected categories based on your winter consumption.
The "12-Month Lock" Rule:
Your status (Protected or Non-Protected) is decided ONLY by your average usage during the 4 winter months (Nov-Feb). Once decided, this status applies to your bill for the entire year (March to October included).
| Category | Criteria (Winter Avg) | Rate / MMBTU | Fixed Monthly Charge |
|---|---|---|---|
| Protected | Below 0.9 hm3 | Rs. 200 - Rs. 350 | Rs. 600 |
| Non-Protected | 0.9 to 1.5 hm3 | Rs. 500 - Rs. 1,450 | Rs. 1,500 (usage up to 1.5 hm3) |
| Non-Protected | Above 1.5 hm3High Consumption | Rs. 1,900 - Rs. 4,200 | Rs. 3,000 (usage exceeds 1.5 hm3) |
Accuracy note
The calculator is now a rough estimator, not a replacement for the official bill. Official SNGPL and SSGC calculations use meter type, pressure, GCV, standard cubic meters, MMBTU conversion, slab rules, fixed charges, meter rent, GST, arrears, rebates, and adjustments.
Real Life Example: The "Summer Trap"
Scenario: You used too much gas in January (Winter) and lost your Protected Status.
Result in July (Summer): You barely use any gas in July (e.g., only 0.3 hm3). However, because your status is locked as Non-Protected, you will STILL be charged the Non-Protected Fixed Charge (Rs. 1,500+) and Non-Protected rates.
This is why gas bills remain high in summer for many consumers.
What is hm3 in Gas Bill?
hm3 stands for Hecto Cubic Meters. It is the standard unit used by Sui Gas companies (SNGPL & SSGC) to measure the volume of gas you have consumed. This is converted to MMBTU (Million British Thermal Units) using the GCV (Gross Calorific Value) to calculate your final bill amount.
How to calculate hm3 in gas bill from meter reading?
To calculate your hm3 manually:
1. Take your Present Meter Reading.
2. Subtract your Previous Meter Reading (found on your last bill).
3. The difference is your raw gas consumption. Depending on your meter type, you divide this difference by 100 to get your consumption in hm3.
Alternatively, use our calculator above for a rough estimate before you compare it with the official bill.
What is Rebate Adjustment in Gas Bill?
A Rebate Adjustment is a deduction or discount on your total bill. This usually happens if you were accidentally overcharged in a previous month, or if you qualify for a specific government subsidy. If you see a rebate, your payable amount decreases.
Frequently Asked Questions
How to calculate Sui Gas bill?+
Enter your current and previous meter readings into the calculator above. It gives a rough estimate using current domestic slab rates, but your official SNGPL or SSGC bill can differ because of GCV, pressure, adjustments, arrears, rebates, and exact billing rules.
What is the 12-month lock rule for Protected Consumers?+
Your Protected or Non-Protected status is determined strictly by your average gas usage during the 4 winter months (Nov-Feb). Once set, this tariff category is locked and applied to your bill for the entire year, including summer months.
Why is my gas bill so high in summer even with low usage?+
If you lost your Protected status during winter due to high usage, you are locked into the Non-Protected category. You must pay the higher fixed charge (Rs. 1,500-Rs. 3,000) every month, even if you use very little gas in summer.
