How Natural Gas Bills Work
Gas bills typically include a fixed delivery fee plus a per-therm usage charge.
Formula
Monthly Bill = Base Fee + (Therms Used x Rate Per Therm)
One therm = 100,000 BTU of natural gas energy.
Example Calculation
50 therms per month at $1.20/therm with $12 base fee.
- 01Usage charge = 50 x $1.20 = $60.00
- 02Total bill = $12.00 + $60.00 = $72.00
- 03Annual estimate = $72.00 x 12 = $864.00
