How Natural Gas Bill Calculator Works
This tool works by converting meter usage into therms, applying the entered supply and delivery rates, adding fixed charges, and adding taxes.
- Step 1
Enter meter usage
Type usage in hundred cubic feet (ccf), thousand cubic feet (Mcf), therms, or cubic meters (m³).
- Step 2
Enter the therm factor
Type the therm factor printed on the bill, such as 1.037 therms per ccf.
- Step 3
Enter tariff rates
Add the supply rate, delivery rate, and fixed customer charge from the tariff.
- Step 4
Add taxes and read the bill
Add the tax percentage and read the itemized bill total.
Natural Gas Bill Calculator Formula
The formula adds usage charges and fixed charges, then applies tax.
Therms = ccf × Therm Factor
Usage Charge = Therms × (Supply Rate + Delivery Rate)
Bill = (Usage Charge + Fixed Charge) × (1 + Tax %)
- Therm Factor
- = heat content of the gas, set monthly by the utility
- Supply Rate
- = price of the gas itself per therm
- Delivery Rate
- = price per therm for pipeline delivery
Worked Example
- A home uses 82 ccf with a therm factor of 1.037 = 85 therms (2,491 kWh).
- Usage charge = 85 × ($0.55 supply + $0.65 delivery) = $102.00.
- Subtotal with a $12.50 customer charge = $114.50.
- Bill with 5% tax = $120.23.
Natural Gas Bill Calculator Conversion Table
The table converts ccf into therms and kilowatt-hours (kWh) and shows the bill at $1.20 per therm, a $12.50 customer charge, and 5% tax.
| Usage (ccf) | Therms | kWh | Usage Charge | Bill with Tax |
|---|---|---|---|---|
| 10 | 10.4 | 304 | $12.44 | $26.19 |
| 20 | 20.7 | 608 | $24.89 | $39.26 |
| 40 | 41.5 | 1,216 | $49.78 | $65.39 |
| 60 | 62.2 | 1,823 | $74.66 | $91.52 |
| 80 | 83.0 | 2,431 | $99.55 | $117.65 |
| 100 | 103.7 | 3,039 | $124.44 | $143.79 |
| 150 | 155.5 | 4,559 | $186.66 | $209.12 |
| 200 | 207.4 | 6,078 | $248.88 | $274.45 |
1 therm = 100,000 British thermal units (BTU) = 29.3 kWh. In the UK, bills convert m³ to kWh with: m³ × 1.02264 × calorific value ÷ 3.6.
What is a Natural Gas Bill Calculator?
A Natural Gas Bill Calculator is a utility cost tool that applies entered usage and tariff rates to estimate a natural gas bill.
Gas bills mix units and charges: the meter reads in ccf or m³, the rates are in therms or kWh, and fixed charges and taxes sit on top. The Natural Gas Bill Calculator follows the same order the utility uses, so the estimate matches the bill line by line.
The tool helps households check a bill, estimate the next one from a meter reading, or budget for a new home.
What are the uses of a Natural Gas Bill Calculator?
There are 4 main uses of the Natural Gas Bill Calculator, including bill checks, mid-cycle estimates, and new home budgets.
Check a bill
Recalculate the bill from the meter reading and tariff.
Estimate mid-cycle
Read the meter mid-month and project the bill.
Budget a new home
Estimate bills from the previous owner’s usage.
