ⓘ About this tool 🔄 Last updated 1 Sep 2026 ✓ Reviewed by TopToolAI Team

Estimate your gas or utility bill from units consumed, the rate per unit, and any fixed charge — a quick way to sanity-check a bill before it arrives. 45 units consumed at PKR 220 per unit plus a PKR 150 fixed meter charge comes to PKR 10,050 for the month — a quick way to catch a billing error before you pay.

How to use Gas Bill Calculator

Step-by-step guide to the boxes below. Open it only if you need help.

  1. 1
    Gas company Choose one

    Choose the company printed on your bill, SNGPL or SSGC. Each one has its own rate slabs, so the wrong choice gives a wrong bill.

    Choose one: SNGPLSSGC

  2. 2
    Gas units consumed (HM3) Number

    Look on your last bill for the units consumed in HM3, or subtract the old meter reading from the new one. Decimals are fine, like 1.5.

    Example: 1.5

  3. 3
    Press “Calculate”

    Click the button under the boxes. If something is missing or not valid, a short message tells you which box to fix.

  4. 4
    Read your result

    You get a slab-by-slab breakdown, the fixed charge, GST and an estimated total bill. Change any box and try again to compare different numbers.

Slab rates and fixed charges shown are illustrative estimates only — not official OGRA/SNGPL/SSGC tariffs. Confirm exact current rates with your gas company.

Gas Bill Calculator FAQs

Why might my real bill differ from this estimate?
Many utility providers use tiered/slab pricing (different rates for different usage bands) rather than one flat rate, plus separate taxes or surcharges not included here.
How is the fixed meter charge worked out?
It's applied automatically based on the gas company you select — you don't need to enter it yourself, just pick SNGPL or SSGC and it's included in the total.
Why does the rate change depending on how much gas I use?
This is slab/tiered billing — the first block of units is charged at one rate, the next block at a higher rate, and so on, similar to income tax brackets.
Does this include GST?
Yes, the breakdown shows GST calculated on the gas charges separately, alongside the fixed meter charge, so you can see exactly how the total is built up.
