SSGC Bill Tools & Calculators
A duplicate bill tells you what you owe. These four tools tell you whether it looks right, what next month will cost, and what happens if you pay late. Everything runs in your browser — nothing you type is sent anywhere or stored.
SSGC Bill Calculator
What will this month cost?
Enter your HM3 consumption and tariff category to see the bill built up line by line — slab rate, gas charge, fixed charges, meter rent, GST and arrears. It also warns you how much headroom is left before the next slab re-prices your entire month.
- Protected and non-protected slab rates
- Slab-rate and telescopic methods side by side
- Next-slab warning with the rupee cost of crossing it
- Adjustable heating value
Gas Unit Converter
HM3, m³, CFT and MMBTU
Convert between every unit that appears on a Sui gas bill, in both directions. Volume conversions are exact; MMBTU depends on the heating value, which you can set to the figure printed on your own bill.
- All four units at once for any input
- Heating value defaults to 3.53 MMBTU per HM3
- One-click swap between units
- Reference table at the slab boundaries
Meter Reading Calculator
Is the bill telling the truth?
Put in your previous and present meter readings and get units consumed, a daily rate, an estimated cost and a projection for the full month. The fastest way to catch a wrong or estimated reading before you pay it.
- Accepts cubic metres or HM3
- Daily rate and 30-day projection
- Flags a reading lower than the previous one
- Shows your remaining slab headroom
Late Payment Calculator
What does being late cost?
See the 10% surcharge on an overdue bill, what it becomes if carried into another cycle, and the disconnection timeline that follows. Then add the due date to your calendar with a reminder two days out.
- Surcharge from your bill amount and dates
- Second-cycle compounding shown explicitly
- Downloadable calendar reminder (.ics)
- What happens, and when, after the due date
A five-minute monthly routine
Used on their own the tools are handy. Used in sequence, once a month, they mean you never pay a bill you have not checked.
- 1
Read your meter
Photograph it on roughly the same date each month and note the figure.
Go - 2
Work out your own consumption
Two readings give you HM3 used and an estimated cost before the bill arrives.
Go - 3
Compare with the real bill
Pull the duplicate bill from SSGC’s portal and check the readings and the total against yours.
Go - 4
Diarise the due date
One click adds it to your calendar with a reminder, and the surcharge never applies.

Why these are estimates, and why that is fine
We do not have access to your account, the heating value applied to your area this month, or any adjustment SSGC has made. So the calculators give you a well-informed estimate, not an invoice — and that is genuinely useful: an estimate that lands within a few hundred rupees of your bill tells you the bill is sound, and one that is wildly out tells you something needs checking. Pay the amount printed on the official bill, always.
