Type in the hm3 of gas used and the GCV shown on your SSGC bill. A protected home using 0.8 hm3 at GCV 990, the figure SSGC uses in its own rate examples, pays about Rs 1,790. The same gas on non-protected rates costs about Rs 4,970.
SSGC is Sui Southern Gas Company, supplying Sindh and Balochistan. The domestic prices of 1 July 2025 remain in force for 2026-27.
Worked example: 0.8 hm3, protected, GCV 990
First convert to MMBTU: 80 m³ ÷ 28.17385 × 990 ÷ 1,000 = 2.81 MMBTU.
0.8 hm3 falls in the protected 0.6 to 0.9 slab (Rs 350). SSGC gives the benefit of one previous slab, so the gas up to 0.6 hm3 is charged at Rs 300.
| Line | Working | Rs |
|---|---|---|
| Gas charges | 2.108 × 300 + 0.703 × 350 | 878.47 |
| Fixed charge | protected | 600.00 |
| Meter rent | 40.00 | |
| GST | 18% | 273.32 |
| Total | 1,791.79 |
On non-protected rates the same 0.8 hm3 would cost Rs 4,968.46, mainly because the rates are Rs 850 and Rs 1,250 and the fixed charge is Rs 1,500.
Who is protected
SSGC treats a home as protected if its average gas use in the peak winter months, November to February, was 0.9 hm3 or less. The status is based on past winters, not on one month.
Protected bills at GCV 990:
- 0.25 hm3: Rs 962.51
- 0.5 hm3: Rs 1,221.67
- 0.8 hm3: Rs 1,791.79
- 0.9 hm3: Rs 1,936.92
If you enter more than 0.9 hm3 with protected selected, the calculator switches to non-protected rates.

Fixed charge: Rs 600 protected; Rs 1,500 non-protected up to 1.5 hm3, Rs 3,000 above. Meter rent Rs 40. GST 18%. These are for a 30-day bill; the calculator scales the fixed charge, meter rent and slab limits by the days in your reading period.
GCV and your bill
The GCV (gross calorific value) is printed on your bill in BTU per cubic foot. It changes slightly each month. The calculator starts at 990, the GCV SSGC uses in its own rate examples. For the closest estimate, type the GCV from your latest bill.
The SSGC conversion is: MMBTU = (m³ ÷ 28.17385) × GCV ÷ 1,000. SSGC also notes that withholding tax can apply. That is not included here. For electricity in Karachi, use the K-Electric bill calculator.
SSGC prints the GCV for your area on each bill; the 990 used to start this calculator comes from SSGC's own examples, so replace it with yours. qaaf has no link with SSGC or OGRA, and the estimate leaves out arrears, withholding tax and other bill lines. After the due date a 10% late payment surcharge applies to homes. The amount on your SSGC bill is the one to pay.
Questions people ask
What is the SSGC per unit gas price?
SSGC prices gas per MMBTU. Protected homes pay Rs 200 to Rs 350 and non-protected homes Rs 500 to Rs 4,200, depending on the slab. These are the prices of 1 July 2025, kept unchanged for 2026-27.
How is the SSGC slab benefit applied?
SSGC gives the benefit of the preceding slab only. The gas up to the previous slab limit is charged at that slab rate, and the rest at the rate for your slab. The calculator applies this rule.
Why is my SSGC bill higher than this estimate?
Your GCV may differ from the starting 990, and the bill may carry arrears, late payment surcharge or withholding tax. Also check whether you are billed as protected or non-protected. Use the exact hm3 and GCV from your bill.
Is SSGC cheaper than SNGPL?
No. Both use the same domestic price schedule. The SNGPL gas bill calculator gives the same result for the same hm3 and GCV.
