Natural gas bills vary by marketer and service provider (local city or utility) therefore descriptions and charges may be different. Below are descriptions and charges that are typically found on marketer natural gas bills.

If you receive your natural gas from a Municipal gas system the charges usually are identified as usage (CCF, MCF, or therm).  To calculate your bill, multiply your natural gas usage by your per unit gas rate.  The base charge is a fixed monthly charge that remains the same each month while the usage charge varies depending on the amount of natural gas used.
