Estimated Bill
Calculator methodology
Last checked against currently published official guidance: August 26, 2026. 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.
| Category | Status and current usage | Rate / MMBTU | Fixed Monthly Charge |
|---|---|---|---|
| Protected | Nov-Feb average up to 0.9 hm3Current month up to 0.9 hm3 | Rs. 200 - Rs. 350 | Rs. 600 |
| Non-Protected | Non-Protected status, or a Protected account above 0.9 hm3 this monthCurrent month up to 1.5 hm3 | Rs. 500 - Rs. 1,450 | Rs. 1,500(usage up to 1.5 hm3) |
| Non-Protected | Non-Protected status, or a Protected account above 0.9 hm3 this monthCurrent month above 1.5 hm3 | Rs. 1,900 - Rs. 4,200 | Rs. 3,000(usage exceeds 1.5 hm3) |
Complete Domestic Gas Slab Rates
The following are the published domestic system-gas sale prices effective from July 1, 2025. Gas tariff rates are calculated on an MMBTU basis, rather than being charged directly per cubic-meter reading.
Protected Consumer Rates
| Monthly Usage | Rate (Rs./MMBTU) |
|---|---|
| Up to 0.25 hm³ | Rs. 200 |
| Up to 0.50 hm³ | Rs. 250 |
| Up to 0.60 hm³ | Rs. 300 |
| Up to 0.90 hm³ | Rs. 350 |
Non-Protected Consumer Rates
| Monthly Usage | Rate (Rs./MMBTU) |
|---|---|
| Up to 0.25 hm³ | Rs. 500 |
| Up to 0.60 hm³ | Rs. 850 |
| Up to 1.00 hm³ | Rs. 1,250 |
| Up to 1.50 hm³ | Rs. 1,450 |
| Up to 2.00 hm³ | Rs. 1,900 |
| Up to 3.00 hm³ | Rs. 3,300 |
| Up to 4.00 hm³ | Rs. 3,800 |
| Above 4.00 hm³ | Rs. 4,200 |
Domestic consumers generally receive the benefit of one preceding slab when the applicable billing calculation allows it. For consumption above 4 hm³, the Rs. 4,200 rate applies without the preceding-slab benefit.
Gas Bill Calculator Accuracy Note
The calculator uses the applicable domestic system-gas rates together with pressure and GCV conversion, the preceding-slab benefit where applicable, minimum gas charges, fixed charges, meter rent, and estimated GST.
It is designed to provide an estimated bill amount for planning purposes. It does not calculate account-specific items such as monthly RLNG tariffs, arrears, rebates, late-payment charges, or other adjustments. Therefore, your official SNGPL or SSGC bill should always be treated as the final payable amount.
Where to Find Calculator Values on Your Gas Bill
The names and locations of billing fields can vary slightly between SNGPL and SSGC bills. However, the information needed for an estimate is normally available in the following sections.
Current and Previous Meter Reading
Look for the Present Meter Reading and Previous Meter Reading in the meter-reading section of your bill.
Use the actual cubic-meter readings and do not include the reading date when entering values into the calculator.
Protected or Non-Protected Category
Check the tariff, consumer category, or billing information section of your latest bill.
If the bill clearly identifies your account as Protected or Non-Protected, selecting the printed category is generally the simplest way to configure the calculator.
Gas Consumed in hm³
For determining the applicable consumer category, check the monthly-history section of your bill.
When the calculator asks for winter consumption, use the monthly hm³ values for November, December, January, and February, rather than entering the four meter readings themselves.
Pressure and GCV
Look around sections containing terms such as Gas Consumed, Pressure, Factor, MMBTU, or GCV.
These values may be optional in the calculator, but entering the pressure and Gross Calorific Value (GCV) from your bill can make the estimated volume-to-energy conversion more closely reflect the information shown on your account.
Four-Month Category Example
Suppose the winter consumption values shown on a bill are:
- November: 0.72 hm³
- December: 0.85 hm³
- January: 1.04 hm³
- February: 0.79 hm³
The four-month total is 3.40 hm³, giving an average of 0.85 hm³.
Because the average is not above 0.90 hm³, this example falls within the stated Protected threshold under the calculation described above.
However, the consumer category and actual billing treatment should always be confirmed from the latest official bill and applicable rules. Current-month consumption can also affect the estimated charges for that month.
Real-Life Example: The "Summer Trap"
Scenario
Suppose your average consumption during November, December, January, and February was above the applicable threshold, resulting in a Non-Protected classification.
What Can Happen in Summer?
Even if your July consumption falls to around 0.3 hm³, your bill may still reflect the applicable Non-Protected category and its associated fixed charges and tariff rates.
This is one reason some consumers may notice that their gas bill remains relatively high during summer despite using less gas than they did during the winter months.
Always check the category and charges printed on your latest official bill rather than assuming that lower summer consumption automatically changes the consumer category.
What Is hm³ in a Gas Bill?
On domestic gas bills, hm³ is a unit used to express gas volume. One hm³ represents 100 cubic meters, so 0.90 hm³ equals 90 cubic meters.
The billing process can apply technical conversion factors to the metered gas volume to obtain a standard volume. The standardized volume is then converted into MMBTU using the applicable GCV (Gross Calorific Value) for tariff calculation.
How to Calculate hm³ from Gas Meter Readings
You can make a basic estimate of your gas consumption from your meter readings:
- Take the Present Meter Reading from your current bill.
- Find the Previous Meter Reading on the same bill or your previous bill.
- Subtract the previous reading from the present reading.
- The difference represents the basic metered consumption in cubic meters.
- Divide the cubic-meter figure by 100 to convert it into a basic hm³ value.
For example, if the present reading is 1,250 and the previous reading is 1,170:
1,250 − 1,170 = 80 cubic meters
80 ÷ 100 = 0.80 hm³
This is a basic volume calculation. The billed hm³ may differ because the official billing calculation can apply pressure, temperature, meter, and other technical conversion factors.
For a quick planning estimate, you can use the calculator above and compare its result with your official bill.
What Is Rebate or Adjustment in a Gas Bill?
A Rebate or Adjustment is an amount added or deducted to correct or reconcile a previous billing entry.
Depending on the account and reason for the adjustment, it may relate to a provisional bill, corrected meter reading, tariff correction, previous overcharge, billing error, or another account-specific reconciliation.
- A negative adjustment generally reduces the amount payable.
- A positive adjustment can increase the amount payable.
The exact reason should be confirmed from the description or adjustment details printed on your official SNGPL or SSGC bill.
Frequently Asked Questions
Find answers to common questions about domestic gas slab rates, hm³, MMBTU, protected and non-protected consumers, and gas bill calculations.
What is hm³ in a gas bill? +
hm³ is a unit used to express gas volume. One hm³ equals 100 cubic meters, so 0.90 hm³ represents 90 cubic meters. The official billing system may apply technical conversion factors before calculating the final bill.
What is MMBTU in a gas bill? +
MMBTU stands for Million British Thermal Units and represents the energy content of natural gas. Gas tariffs are generally calculated using the energy value of gas rather than simply charging a fixed amount per cubic meter.
How can I calculate hm³ from my meter readings? +
Subtract your previous meter reading from your present meter reading to find basic consumption in cubic meters. Divide the result by 100 to get a basic hm³ figure. The billed value may differ because official billing can apply pressure and other technical conversion factors.
What is the difference between Protected and Non-Protected consumers? +
Protected and Non-Protected consumers are billed under different applicable tariff structures. The consumer category can depend on the relevant consumption history and rules. Always check the category printed on your latest official gas bill.
What are the current domestic gas slab rates? +
Domestic gas slab rates vary according to the applicable consumer category and consumption level. The calculator uses the published domestic system-gas rates configured for the calculation. Always compare the estimate with your latest official bill.
Does the gas bill calculator show the exact payable amount? +
No. The calculator provides an estimated amount for planning and comparison. Your official SNGPL or SSGC bill can differ because of arrears, rebates, late payment charges, adjustments, rounding, billing-period rules, and account-specific charges.
What are Pressure and GCV values used for? +
Pressure and GCV (Gross Calorific Value) are used in converting metered gas volume into a standardized volume and energy value. Entering the values shown on your latest bill can make an estimate closer to the billing information for your account.
Where can I find Pressure and GCV on my gas bill? +
Depending on the bill format, these values may appear near sections labelled Gas Consumed, Pressure, Factor, MMBTU, or GCV. The exact position and label can vary between SNGPL and SSGC bills.
What is a rebate or adjustment on a gas bill? +
A rebate or adjustment is an amount added or deducted to reconcile a previous billing entry. It may relate to a corrected meter reading, tariff correction, provisional billing, previous overcharge, or another account-specific adjustment.
Why can my official gas bill be different from the calculator result? +
The official bill can include items that a planning calculator does not know about, such as previous arrears, rebates, late payment surcharge, account-specific adjustments, applicable taxes, billing-period rules, and other charges. The official bill remains the final source for the payable amount.
Can I use the calculator for both SNGPL and SSGC? +
The calculator can be used as a general planning tool for domestic gas billing, but the actual tariff structure and account-specific charges may vary. Always select the appropriate company and consumer category where the calculator provides those options.
