Natural Gas Cost Per Therm: The LNG Price Truth
Natural Gas Cost Per Therm: The LNG Price Truth
As of April 2026, the average U.S. utility (piped) natural gas cost is $1.68 per therm, with recent monthly readings ranging from $1.676 to $1.749. For liquefied natural gas (LNG) on the global commodity market, the benchmark price reached $13.12 per million BTU (≈$1.31 per therm) in March 2025, while Asian LNG landed spot prices hit $20.81 per MMBtu ($2.08 per therm) in March 2026. The final retail price per therm varies significantly by region due to transportation and distribution costs, utility markup, and contract structure.
What Is a Therm and How Is Natural Gas Priced?
A therm is a standardized unit of heat energy equal to 100,000 British thermal units (BTU), commonly used by U.S. utilities to bill residential and commercial natural gas customers. Natural gas pricing consists of two primary components: the commodity price (based on NYMEX Henry Hub futures) and the basis differential (covering transportation, storage, local production, and delivery costs).
- 1 therm = 100,000 BTU = 0.1 MMBtu
- 1 MCF (thousand cubic feet) ≈ 1.03 therms (varies by gas composition)
- Henry Hub spot price (May 2026): $4.98/MMBtu ≈ $0.50 per therm
- Retail utility price includes commodity + basis + utility margins + taxes
Current Natural Gas Cost Per Therm: Regional and Global Benchmarks
Retail utility prices diverge sharply from wholesale LNG commodity prices due to infrastructure and regulatory factors. The table below presents key price points across markets and timeframes.
| Market / Region | Price (USD) | Unit | Equivalent per Therm | Date |
|---|---|---|---|---|
| U.S. City Average (Utility Piped Gas) | $1.676 | per therm | $1.676 | Apr 2026 |
| Peoples Gas (Chicago-area utility) | $0.3676 | per therm | $0.3676 | Current delivery charge |
| Henry Hub Spot Price | $4.98 | per MMBtu | $0.498 | Jan 2026 |
| Global LNG Benchmark | $13.12 | per MMBtu | $1.312 | Mar 2025 |
| Asian LNG Landed Spot Price | $20.81 | per MMBtu | $2.081 | Mar 2026 |
| U.S. LNG Export Price | $7.57 | per MCF | $0.73 | 2023 |
Factors Driving Natural Gas Cost Per Therm Variability
Energy suppliers must ensure they efficiently use natural gas resources to meet end users' needs, but location-based pricing remains the dominant factor in final therm costs. Several structural elements create price divergence across markets:
- Commodity price volatility: NYMEX Henry Hub futures fluctuate based on supply-demand balance, weather patterns, and storage levels
- Transportation basis: Pipeline capacity constraints and distance from production hubs add $0.20-$1.50 per therm depending on region
- Seasonal demand spikes: Winter heating demand increases prices by 15-30% in cold-climate utilities
- LNG export competition: U.S. export volumes redirect domestic supply, impacting local basis differentials
- Regulatory and utility margins: State public utility commissions approve distribution rate structures that vary by municipality
"The commodity (or NYMEX) plus basis equals the total gas price," explaining why two customers with identical consumption face different per-therm bills.
LNG Market Dynamics and Their Impact on Therm Pricing
Global liquefied natural gas prices have shown less volatility in 2024 and 2025 than prior years, with the benchmark reaching $13.12 per MMBtu in March 2025-an increase from the same period a year earlier. Japan, exclusively reliant on LNG trading, saw landed spot prices reach $10.05 per MMBtu in January 2024, substantially higher than U.S. export prices of $7.57 per MCF in 2023.
The Asian LNG market experienced reduced turbulence in 2023 with price volatility dropping to 75 percent following the exceptionally volatile 2022 period when sanctions on Russian imports surged demand. By March 2026, Asian LNG prices surged to $20.81 per MMBtu, reflecting tight supply conditions and geopolitical factors.
Key concerns and solutions for Natural Gas Cost Per Therm The Lng Price Truth
What is the current natural gas cost per therm in the U.S.?
The April 2026 U.S. city average for utility piped gas is $1.676 per therm, with monthly readings ranging from $1.676 to $1.749 throughout early 2026.
How do you convert MMBtu or MCF to cost per therm?
Divide the price per MMBtu by 10 to get price per therm (since 1 therm = 0.1 MMBtu). For MCF, divide by 10 as well since 1 MCF ≈ 1.03 therms.
Why does natural gas cost per therm vary by location?
Location-based basis differential includes transportation, storage, fuel, and local production costs, creating price differences of $0.20-$1.50 per therm across regions.
What is the difference between wholesale LNG price and retail therm price?
Wholesale LNG commodity prices (e.g., $13.12/MMBtu) exclude distribution infrastructure, utility margins, and regulatory fees that comprise 40-60% of retail therm costs.
How does Henry Hub price relate to my utility bill?
Henry Hub is the NYMEX benchmark commodity price; your utility bill adds basis (transportation/delivery) and utility margins on top, typically doubling or tripling the base commodity cost per therm.
