This calculator estimates your monthly gas bill in Pakistan using the slab-based tariff schedule that OGRA publishes for SNGPL (the northern utility) and SSGC (the southern utility). Enter your monthly MMBTU consumption, select your utility and connection category, and see an itemised estimate.

How Pakistani gas tariffs work — the slab structure
Pakistani gas tariffs follow a progressive slab structure similar to electricity but with different break points and rates. Domestic gas bills typically use slabs at 0.5, 1.0, 2.0, 3.0, and above 4.0 MMBTU per month, with each slab carrying a higher per-MMBTU rate than the previous one. The slab jumps are sharp — moving from 1.9 MMBTU to 2.1 MMBTU can push your bill rate up substantially. Most Pakistani households consuming gas for cooking and a single geyser bill at the lower slabs in summer (1 to 2 MMBTU) and middle slabs in winter (3 to 5 MMBTU) when geyser and heater use spikes.
Beyond the energy charges, gas bills include a fixed minimum charge that applies regardless of consumption (often Rs. 100 to Rs. 300 depending on category), GST at the standard rate, and various smaller adjustments including the GIDC (Gas Infrastructure Development Cess) where applicable. The total bill is the sum of energy charges (slab × MMBTU), fixed components, and applicable taxes.
The calculator's methodology in detail
This estimator uses OGRA's most recently published tariff schedule for each utility, with separate rate tables for SNGPL and SSGC and category-specific rates for domestic, commercial, and bulk connections. When you enter your MMBTU and utility, the JavaScript walks through each applicable slab from the lowest upward, applies the slab rate, and sums the energy charges. Fixed components are added on top to produce the total estimated bill.
The estimate is typically accurate to within 5–15% of an actual bill for standard residential connections. Larger discrepancies often indicate either a recent OGRA tariff revision not yet reflected in this calculator, back-billing from earlier estimated readings, or an unusual GIDC adjustment. The utility's online portal shows the exact rate breakdown applied to your bill — useful for reconciling the calculator estimate against the actual charge.
Practical tips for managing gas consumption
The single largest gas saver in Pakistani households is geyser usage. A standard gas geyser runs for 30 to 90 minutes a day on cold winter mornings, consuming 0.5 to 1.5 MMBTU a month just for hot water. Switching to instant gas geysers (which heat water on demand rather than maintaining a tank temperature) cuts geyser consumption by roughly 40%. Solar water heaters reduce or eliminate the gas-heating load entirely in months with sufficient sunlight.
The second largest lever is cooking efficiency. Lidded pots cook food in roughly half the time of open pots; pressure cookers cut cooking time further. For households cooking three meals a day, an efficient cooking setup can drop cooking-related gas consumption by 30–50% over six months. Across a typical winter month, these combined savings can shift a household from a higher slab to a lower one — translating into 25–40% lower total bills.
Frequent questions about gas bill estimation
How are gas bills measured in Pakistan — what is an MMBTU?
Gas consumption in Pakistan is measured and billed in MMBTU (one million British Thermal Units), a heat-energy unit rather than a volume unit. Your gas meter records the volume of gas that flows through (in cubic feet or cubic meters), and the utility converts that volume into MMBTU based on the gas's energy content. The bill shows MMBTU consumed, the slab rate per MMBTU, and the total energy charge. The conversion happens automatically — you don't need to do volume-to-MMBTU maths to read your bill. For reference, a typical Pakistani household using gas for cooking and a single geyser consumes 1.5 to 3 MMBTU a month; heavier users with central heating may consume 5 to 10 MMBTU.
Why are SSGC bills different from SNGPL bills for the same consumption?
The two utilities operate under separately approved tariff schedules from OGRA, the gas regulator. SNGPL serves the northern half of Pakistan (Punjab, KPK, AJK, parts of Islamabad); SSGC serves Sindh and Balochistan. The slab structures are broadly similar but the rates per slab differ by typically 5 to 15%, reflecting differences in each utility's cost base and customer mix. SSGC has historically been the higher-priced of the two for residential customers. The calculator applies the correct tariff per utility so the estimate matches your actual region.
Does the calculator account for the GIDC (Gas Infrastructure Development Cess)?
GIDC was a separate cess applied on gas consumption for several years, then partially suspended and reinstated multiple times by various regulations. The current applicability and rate varies by consumer category and policy cycle. The calculator includes a typical GIDC component for industrial and commercial categories where it's most consistently applied; for domestic users in 2026 GIDC may or may not be on the bill depending on the latest policy. Treat the calculator estimate as an approximation; consult your actual bill for the live GIDC status.
Why do gas bills in winter cost so much more than summer for the same household?
Two reasons. First, gas consumption actually increases dramatically in winter because gas geysers, heaters, and stoves run more hours per day — many households see consumption double or triple from summer baseline. Second, the slab structure means that doubled consumption doesn't just double the bill — it pushes the entire usage into higher-priced slabs. A household billing at 1.5 MMBTU in summer (Slab 1) might consume 4.5 MMBTU in winter (Slab 3), and the per-MMBTU rate on Slab 3 is several times Slab 1. The combination of higher volume and higher per-unit rates explains why winter gas bills can be five to eight times summer levels.
Can I appeal a gas bill that seems unusually high?
Yes — both SNGPL and SSGC have formal billing-dispute processes. Submit a complaint via the utility's customer-service centre or online portal within 14 days of receiving the disputed bill, attaching the bill copy and any meter photos. The utility will dispatch a meter inspection within 7 to 14 days and either correct the bill (if a meter fault, reading error, or estimated-billing error is found) or confirm the charge. Common legitimate billing errors include estimated readings (when the meter reader didn't visit) and arithmetic errors in slab calculation; if the meter itself is faulty, the utility usually waives a portion of disputed bills pending replacement.
