Gas Bill Calculator

Understanding Natural Gas Bills

Natural gas bills are calculated based on your gas usage measured in therms or CCF (hundred cubic feet). One therm equals approximately 100 cubic feet of natural gas. Understanding your gas bill helps you identify usage patterns, find savings opportunities, and budget effectively for heating costs.

Gas Bill Components

A typical natural gas bill includes several components:

• Gas Supply Charge: Cost of the natural gas itself (per therm or CCF)
• Delivery Charge: Cost to deliver gas to your home (may be tiered)
• Customer Charge: Fixed monthly fee for having service
• Taxes: State and local taxes on gas service
• Total Bill: Sum of all charges plus taxes

Tiered vs Flat Rate

Gas utilities use different rate structures:

• Flat Rate: Same price per therm regardless of usage amount
• Tiered Rate: Price increases as usage increases (encourages conservation)
• Tier 1: Lowest rate for basic usage (e.g., 0-5 therms)
• Tier 2: Medium rate for moderate usage (e.g., 5-15 therms)
• Tier 3: Highest rate for high usage (e.g., 15+ therms)

Unit Conversions

Natural gas is measured in different units:

• 1 Therm: 100,000 BTUs (British Thermal Units)
• 1 CCF: 100 cubic feet ≈ 1.037 therms
• 1 Cubic Meter: ≈ 35.3 cubic feet ≈ 0.353 CCF ≈ 0.368 therms
• Conversion: Most bills show usage in therms or CCF
