Sui Gas Bill Calculator 2026

Enter meter readings for a rough cost estimate. Quickly check Protected/Non-Protected status. The official bill is the final payable amount.

Gas Bill Estimator

Enter the black meter digits from your bill or meter. If you do not know your tariff category, the calculator will show both possible estimates.

Domestic system-gas estimate only. New RLNG connections use a separate monthly tariff.

Calculator methodology

Last checked against currently published official guidance: . This tool gives a planning estimate, not the official payable amount. It converts metered consumption to standard cubic meters using pressure, converts it to MMBTU using GCV, applies the domestic tariff with one preceding-slab benefit and minimum gas charge, then adds fixed charge, meter rent and estimated GST.

For a closer result, select the category printed on your latest bill and copy its pressure and GCV values into the optional accuracy fields. Your official SNGPL or SSGC bill can still differ because of billing-period rules, arrears, rebates, late payment surcharge, provincial or account-specific charges, rounding and other adjustments.

Gas Tariff & Slab Rates 2026

OGRA notifies the natural-gas tariff used by SNGPL and SSGC. The currently published domestic system-gas rates took effect on July 1, 2025. Domestic accounts are classified as Protected or Non-Protected using their average consumption during the four winter months from November through February.

The winter average review:

An average of 0.9 hm3 or less during November-February indicates Protected status; an average above 0.9 hm3 indicates Non-Protected status. Check the category printed on your latest bill. If a Protected consumer exceeds 90 CM in a later month, that particular month is treated as Non-Protected.

CategoryStatus and current usageRate / MMBTUFixed Monthly Charge
ProtectedNov-Feb average up to 0.9 hm3Current month up to 0.9 hm3Rs. 200 - Rs. 350Rs. 600
Non-ProtectedNon-Protected status, or a Protected account above 0.9 hm3 this monthCurrent month up to 1.5 hm3Rs. 500 - Rs. 1,450Rs. 1,500 (usage up to 1.5 hm3)
Non-ProtectedNon-Protected status, or a Protected account above 0.9 hm3 this monthCurrent month above 1.5 hm3Rs. 1,900 - Rs. 4,200Rs. 3,000 (usage exceeds 1.5 hm3)

Complete Domestic Gas Slab Rates

These are the currently published system-gas sale prices, effective July 1, 2025. Rates are charged per MMBTU, not directly per meter unit.

Protected rates

Monthly usageRs./MMBTU
Up to 0.25 hm3200
Up to 0.50 hm3250
Up to 0.60 hm3300
Up to 0.90 hm3350

Non-Protected rates

Monthly usageRs./MMBTU
Up to 0.25 hm3500
Up to 0.60 hm3850
Up to 1.00 hm31,250
Up to 1.50 hm31,450
Up to 2.00 hm31,900
Up to 3.00 hm33,300
Up to 4.00 hm33,800
Above 4.00 hm34,200

Domestic consumers receive the benefit of only one preceding slab. Above 4 hm3, the Rs. 4,200 rate applies without the preceding-slab benefit.

Accuracy note

The calculator uses the current domestic system-gas rates, pressure and GCV conversion, one preceding-slab benefit, minimum gas charge, fixed charges, meter rent and estimated GST. It does not calculate monthly RLNG tariffs, arrears, rebates, late fees or account-specific adjustments, so the official bill remains final.

Where to Find the Calculator Values on Your Bill

The labels can vary slightly between SNGPL and SSGC bills, but the required figures normally appear in these areas:

Current and Previous Reading

Find these in the meter-reading section. Use the black cubic-meter digits and do not include the reading date.

Protected or Non-Protected

Check the tariff or consumer-category area. When it is available, this printed category is the simplest option to select.

Gas Consumed hm3

Use the monthly-history values for November, December, January and February—not the four meter readings.

Pressure and GCV

Look near Gas Consumed, Pressure/Factor, MMBTU or GCV. These optional values make the volume and energy estimate closer.

Four-month category example

If the winter hm3 values are 0.72, 0.85, 1.04 and 0.79, their total is 3.40 and the average is 0.85 hm3. Because 0.85 is not above 0.9 hm3, the winter average indicates Protected status. Current-month usage above 90 standard CM is still estimated as Non-Protected for that month.

Real Life Example: The "Summer Trap"

Scenario: Your average consumption across November, December, January and February exceeded 0.9 hm3, placing the account in the Non-Protected category.

Result in July (Summer): Even if July consumption is only 0.3 hm3, a bill that still shows Non-Protected can carry the Rs. 1,500 fixed charge and Non-Protected rates.

This is why gas bills remain high in summer for many consumers.

What is hm3 in Gas Bill?

On SNGPL and SSGC domestic bills, hm3 represents hundreds of cubic meters: 0.9 hm3 equals 90 standard cubic meters. The bill converts metered volume to standard volume using technical factors and then converts that volume into MMBTU using GCV (Gross Calorific Value).

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 consumption in cubic meters for a standard domestic cubic-meter meter. Divide it by 100 for a basic hm3 figure. The billed hm3 can differ after pressure and other technical factors are applied.
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 or Adjustment is a billing correction carried forward by SNGPL or SSGC. It may relate to a provisional bill, corrected meter reading, tariff correction, earlier overcharge or another account-specific reconciliation. A negative adjustment normally reduces the payable amount, while a positive adjustment can increase it; check the description on the official bill.

Frequently Asked Questions

How to calculate Sui Gas bill?+

Enter your current and previous meter readings. Select the category shown on your latest bill, calculate it from the Gas Consumed hm3 values on the four November-February bills, or ask the calculator to show both possibilities. For a closer result, copy the pressure and GCV from a recent bill.

How is Protected or Non-Protected status reviewed?+

Your category is based on average consumption during November-February. An average up to 0.9 hm3 indicates Protected status; above 0.9 hm3 indicates Non-Protected status. A Protected consumer exceeding 90 CM in a later month is treated as Non-Protected for that month.

What if I do not know my tariff category?+

Choose “I don't know” to see both Protected and Non-Protected estimates. The calculator will not classify low current-month usage as Protected without winter history. If current usage exceeds 90 standard CM, that month is estimated at Non-Protected rates.

Why is my gas bill so high in summer even with low usage?+

If your winter average moved you into the Non-Protected category, the higher fixed charge can continue in later months until the next category review. You may pay Rs. 1,500-Rs. 3,000 even when current summer usage is low.
