Enter your monthly gas use in hm³ and your protected status to estimate the SNGPL/SSGC bill — gas charge, fixed charge and meter rent, before tax.
What Is a Pakistan Gas Bill Calculator?
A Pakistan gas bill calculator estimates the SNGPL/SSGC bill: 1 hm³ non-protected → gas charge Rs 3,535.00 + fixed/meter Rs 1,540.00 = Rs 5,075.00 before tax. It applies the one-preceding-slab benefit (only the units above the previous slab pay your slab’s rate), the Rs 3.5 MMBtu-per-hm³ conversion, and the correct fixed charge. Slabs per OGRA’s 29 June 2025 notice, unchanged for FY2026-27 — last verified October 2026.
How to Use
- Enter monthly use in hm³ (from your bill).
- Pick protected or non-protected.
- Click “Estimate Bill”.
Formula
Gas charge = MMBtu × slab rate with one-preceding-slab benefit; 1 hm³ ≈ 3.5 MMBtu; + fixed charge + Rs 40 meter rent; GST extra.
Worked Example
1 hm³ non-protected: 0.6 hm³ (2.1 MMBtu) at Rs 850 = Rs 1,785.00; 0.4 hm³ (1.4 MMBtu) at Rs 1,250 = Rs 1,750.00; gas = Rs 3,535.00; + Rs 1,500 fixed + Rs 40 rent = Rs 5,075.00 before tax.
How It Works, In Plain Words
There are only two inputs. The first is your monthly use in hm³, the volume figure printed on your bill. The second is your consumer status, protected or non-protected, because the two groups are billed from different slab tables with different fixed charges. The tool first converts your hm³ into MMBtu at 3.5 MMBtu per hm³, the conversion in the Formula line, because slab rates are charged per MMBtu. It then finds the slab your use falls into and applies the one-preceding-slab benefit: the portion up to the previous slab’s top is charged at that slab’s rate, and only the rest pays your own slab’s rate. That split is the whole story of the worked example — 0.6 hm³ (2.1 MMBtu) at Rs 850 gives Rs 1,785.00, and the remaining 0.4 hm³ (1.4 MMBtu) at Rs 1,250 gives Rs 1,750.00, so the gas charge is Rs 3,535.00. The fixed charge and the Rs 40 meter rent are then added: Rs 1,500 fixed in the example, shown together as Rs 1,540.00, bringing the estimate to Rs 5,075.00 before tax.
The estimate deliberately stops before tax. The note under the result says GST and other charges on your bill come on top, and the last FAQ explains why a real bill can still differ — GST, meter rent timing, GCV differences and any arrears or adjustments. Read the figure as a close pre-tax estimate to check against the printed bill rather than the payable amount itself. The slabs behind it follow OGRA’s 29 June 2025 notice, unchanged for FY2026-27.
Real-World Uses
A tenant splitting a shared household bill copies the hm³ figure from the meter reading and estimates the month’s gas cost before the printed bill arrives, knowing the shape of the answer in advance from the worked example — a gas charge plus the fixed charge and Rs 40 meter rent, before tax. A homeowner watching winter use climb checks the protected question directly: protected status turns on an average of 0.9 hm³ or less over last November to February, so they run the estimator both ways to see what the status is worth and whether cutting back could recover it next winter. A small shopkeeper lining up monthly utility budgets runs this estimator next to the electricity bill calculator, so both utility estimates sit side by side before tax, with GST still to come on the gas side.

Common Mistakes
- Treating it as the final bill — GST and adjustments come on top
- Using hm³ vs MMBtu interchangeably
- Assuming protected status — it depends on last winter’s average
Common Mistakes to Avoid
The list above names the three big ones, and each has a simple guard. Treating the estimate as the final bill comes first: the total is labelled before tax for a reason, because GST and other charges come on top, so compare the estimate with the pre-tax lines of your printed bill, not with the payable total. Mixing up hm³ and MMBtu is second: the slab rates apply per MMBtu, which is why the tool converts first at 3.5 MMBtu per hm³ — never type an MMBtu figure into the hm³ box. Assuming protected status is third: that status is earned by last winter’s average of 0.9 hm³ or less over November to February, not chosen at the meter. If you are not sure which group you are in, run both and budget on the non-protected figure.
FAQ
What is 1 hm³ of gas in MMBtu?
About 3.5 MMBtu at typical GCV — your bill prints the exact factor.
What is a protected consumer?
Average use ≤ 0.9 hm³ over last Nov–Feb — they get the cheap slabs.
What is the one-preceding-slab benefit?
Units up to the previous slab’s top are charged at that slab’s rate — only the rest at your slab’s rate.
Are these the current slabs?
Yes — OGRA’s 29 June 2025 notice, unchanged for FY2026-27; last verified October 2026.
Why is my bill higher than the estimate?
GST, meter rent timing, GCV differences and any arrears/adjustments.
Why does the estimate split my gas into two parts?
Because of the one-preceding-slab benefit. In the worked example, 1 hm³ non-protected is billed as 0.6 hm³ (2.1 MMBtu) at Rs 850 plus 0.4 hm³ (1.4 MMBtu) at Rs 1,250 — Rs 1,785.00 + Rs 1,750.00 = Rs 3,535.00. Only the units above the previous slab’s top pay your slab’s higher rate, so crossing into a new slab never re-prices the whole month at the top rate.
What does the Rs 1,540.00 line in the example cover?
The fixed charge plus the meter rent, before tax. In the worked example the fixed charge is Rs 1,500 and the meter rent is Rs 40, shown together as Rs 1,540.00 — which is why the total reads Rs 3,535.00 + Rs 1,540.00 = Rs 5,075.00. These charges sit on top of the gas charge whatever the month’s use, so they are the floor of every estimate the tool produces.
