Frequently asked questions
How much does propane cost per month?
For a home heating with propane, $150–$400 a month in winter is common, dropping to near zero in summer. The exact figure depends on home size, climate, and the price per gallon you pay — enter your usage above for your number.
How do I budget for winter heating fuel?
Estimate your heating-season usage, multiply by your expected price, and divide by 12 to set aside a steady monthly amount — even though most of the spend lands in a few cold months. Locking a pre-buy or budget-plan price removes the guesswork.
Is a propane pre-buy contract worth it?
A pre-buy locks your price before winter, which protects you if prices rise but costs you if they fall. It’s most valuable if you have steady, predictable usage and want budget certainty. Summer is typically the cheapest window to lock a rate.
How much does heating fuel cost per year for a house?
A typical home spends roughly $1,000–$3,000 a year on heating fuel depending on fuel type, climate, and home size. Tracking your actual gallons and price over time gives you a far more accurate annual figure than national averages.
