Enter your monthly gas consumption in HCF to see a rough PKR estimate using SNGPL domestic slab-based tariff rates. Your actual bill also depends on meter rent, exact OGRA tariff revision, arrears, and surcharge — always verify with your official SNGPL bill before paying.
Enter your monthly gas consumption
Use the “Units consumed (HCF)” line from your SNGPL bill, or estimate your monthly usage in Hecto Cubic Feet. 1 HCF ≈ 2.83 cubic meters.
Estimated gas bill (PKR)
Rs 543.98
Up to 0.5 HCF (0.5 × Rs 121)Rs 60.5
0.5 – 1 HCF (0.5 × Rs 121)Rs 60.5
1 – 2 HCF (1 × Rs 300)Rs 300
Meter rent (fixed)Rs 40
GST (18%)Rs 82.98
Important: This calculator uses illustrative SNGPL domestic slab rates for estimation only. OGRA revises gas tariffs periodically. Meter rent, GST percentage, arrears, and line items on your actual SNGPL bill may differ. CheckBills.pk does not guarantee accuracy.
The calculator takes your monthly consumption in HCF (Hecto Cubic Feet) and applies the progressive SNGPL domestic slab rates. Each slab has a different per-HCF rate — as usage increases, higher-priced slabs kick in. The tool then adds meter rent and GST to estimate your total monthly gas bill.
Understanding SNGPL Gas Slab Rates
SNGPL follows an incremental/progressive slab system for domestic consumers, approved by OGRA. The first 0.5 HCF is at the lowest rate (protected/lifeline), and rates increase as consumption rises. Consumers using above 5 HCF per month face the highest slab rate of approximately Rs 1,107/HCF.
Up to 0.5 HCF: Minimum / lifeline charges
0.5 – 1 HCF: Rs 121/HCF
1 – 2 HCF: Rs 300/HCF
2 – 3 HCF: Rs 553/HCF
3 – 5 HCF: Rs 738/HCF
Above 5 HCF: Rs 1,107/HCF
What Is HCF and How to Read Your Meter
HCF (Hecto Cubic Feet) equals 100 cubic feet of gas. Your SNGPL gas meter displays a running total in cubic feet or cubic meters. To calculate monthly HCF: subtract the previous reading from the current reading, then divide by 100 if your meter reads in cubic feet (or multiply by 35.315 and divide by 100 if in cubic meters). Your bill already shows consumption in HCF.
Gas Bill Calculator vs. Actual SNGPL Bill
This tool provides a rough estimate. Your actual SNGPL bill may differ because of:
OGRA tariff revisions (rates change with government notifications)
Estimated vs. actual meter readings
Arrears or surcharge from previous unpaid bills
Different consumer categories (commercial/industrial have different rates)
Seasonal adjustments and gas pressure variations
Tips to Lower Your Monthly Gas Bill
Use instant (tankless) geysers — they consume far less gas than storage types.
Fix all gas leaks at pipe joints and stove, even minor ones add up every month.
Cook with pressure cookers and keep lids on pots to trap heat efficiently.
Run the geyser only when needed — never leave it on for hours.
Insulate your home in winter to reduce reliance on gas heaters.
Keep monthly usage below 2 HCF to stay in the affordable slab brackets.
Frequently Asked Questions — Gas Bill Calculator
How does the SNGPL gas bill calculator work?
Enter your monthly gas consumption in HCF (Hecto Cubic Feet) and the calculator applies SNGPL domestic slab rates to estimate energy charges, adds meter rent and GST to give you an approximate total bill amount in PKR.
What is HCF in gas billing?
HCF stands for Hecto Cubic Feet (100 cubic feet). It is the standard unit used by SNGPL to measure gas consumption on your bill. 1 HCF ≈ 2.83 cubic meters.
Are the gas slab rates in this calculator official?
The rates are indicative and based on commonly referenced OGRA-approved domestic tariffs. OGRA revises gas tariffs periodically, so always verify with the latest OGRA notification or your actual SNGPL bill.
Can I use this calculator for SSGC bills?
This calculator uses SNGPL (Sui Northern) slab rates. SSGC (Sui Southern) has different tariff slabs. For SSGC, the rates may differ — use this only as a rough reference.
How can I reduce my gas bill?
Use instant geysers instead of storage ones, fix gas leaks, cook efficiently with pressure cookers, limit geyser run time, and insulate your home in winter. Keeping consumption under 2 HCF keeps you in cheaper slabs.
What additional charges appear on my gas bill besides gas usage?
Your SNGPL gas bill includes meter rent (fixed monthly charge), GST (General Sales Tax) on all charges, and possibly arrears or late-payment surcharge from previous months.
