How This Calculator Works

State Pricing

Prices are sourced from EIA residential propane data, April 2026. Each state uses its specific per-gallon average, not the national average.

Home Size Scaling

A 2,000 sqft home is the baseline. Every 500 sqft above or below adjusts furnace consumption proportionally.

Climate Multipliers

Mild (0.7x): Gulf Coast, Southwest. Moderate (1.0x): Mid-Atlantic, Midwest. Cold (1.4x): Northeast, Northern states.

Appliance Baselines

Annual gallon consumption per appliance based on industry standards. Furnace is adjusted for climate and home size; others are fixed.

Calculator FAQ

How accurate is this propane cost calculator?
This calculator uses EIA state pricing data and industry-standard consumption baselines for each appliance. Results are estimates. Actual consumption varies by home insulation quality, appliance age and efficiency rating, thermostat settings, and local climate patterns. Use this as a planning tool and request actual quotes from local suppliers for exact pricing.
How many gallons does a propane furnace use per year?
A propane furnace in a 2,000 square foot home in a moderate climate uses approximately 800 to 1,200 gallons per year. In cold climates (Minnesota, Vermont, Maine), consumption can reach 1,500 to 2,000 gallons. In mild climates (Texas, Georgia), a furnace may use only 400 to 700 gallons per year.
Does my home size affect propane consumption?
Yes, significantly. Every additional 500 square feet of heated space adds roughly 15 to 20% to furnace consumption. A 3,000 square foot home uses about 50% more propane for heating than a 2,000 square foot home in the same climate.
