How to lower your propane cost

How much does it cost to fill a 5-gallon propane tank in Montana?

About $10.71 for 5 gallons (5 x $2.141 per gallon), based on the EIA weekly residential propane price for Montana, week of Oct 12, 2026. Source: U.S. Energy Information Administration (EIA). Dealer prices vary; updates as new prices come in.

How much does it cost to fill a propane tank in Montana?

Multiply the per-gallon price by the gallons you need. A 500-gallon home tank is filled to about 80% (400 gallons), so at the shown average price that is roughly 400 x the price. Delivery fees and minimums vary by dealer.

Is a tank swap (exchange) cheaper than a refill?

Usually not per gallon. A 20 lb exchange cylinder often holds about 15 lb (about 3.5 gallons), so refilling at a dealer is typically cheaper per gallon. Exchange is faster and more convenient.

When is propane cheapest?

Prices usually dip in late spring and summer. Filling or pre-buying a season contract before October can lower your cost.

How can I lower my propane cost?

Compare dealers, ask about budget or pre-buy plans, own your tank so you can shop around, and improve insulation and thermostat settings.
