How to lower your propane cost
How much does it cost to fill a propane tank in Idaho?
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.
