What 500 Gallons of Propane Buys

500 gallons = 45.75 million BTU. Practical translation depends on what's hooked up:

  • Whole-home heating, 2,000 sqft, moderate climate: 4-5 months (typical residential heating-season fill)
  • Whole-home heating, 2,000 sqft, cold climate: 2.5-3.5 months (often the post-Thanksgiving fill in NE / upper Midwest)
  • Whole-home heating, 3,500 sqft, cold climate: 1.5-2 months, consider sizing the next order at 1,000 gallons
  • Water heating + cooking only: 14-20 months, a single 500-gal fill stretches over a year
  • Backup generator at half load (5 kW continuous): ~330 hours (about 14 days continuous, or 30+ days of cycling backup)
  • Pool heater (50,000 BTU): ~915 hours of operation
  • 20-lb BBQ cylinder refills: ~106 refills

500 Gallons of Propane: FAQ

How much does 500 gallons of propane cost in 2026?
At the latest EIA national residential average of $2.674 per gallon, 500 gallons of propane costs about $1,337. Most suppliers offer a 5-10% volume discount at this size, taking the practical price to roughly $1,230 in mid-priced states. The same 500 gallons in the cheapest state (Nebraska) runs about $821 at retail and as low as $739 with the volume discount. In the most expensive (Florida), 500 gallons hits $2,353 retail or $2,118 with discount. The volume discount typically waives any partial-fill or trip fee that would otherwise be added.
Is 500 gallons a normal residential propane order?
Yes, it's the most common residential delivery size in the US. A standard 500-gallon home tank holds 400 usable gallons (the 80% fill rule), so a top-up after the tank is roughly 1/4 full takes about 300 gallons, and a full fill from near-empty takes 380-400 gallons. Suppliers consider 500 gallons to be a 'will-call' or 'keep-full' standard delivery, not a partial fill. Most homes that heat with propane fill 2-3 times per year in this range.
What does 500 gallons of propane heat?
500 gallons delivers roughly 45.75 million BTU. In a 2,000 sqft home in moderate climate (mid-Atlantic, lower Midwest), 500 gallons covers about 4-5 months of whole-home heating including water heating, cooking, and a propane fireplace. In cold climates (New England, upper Midwest, Mountain West), expect 2.5-3.5 months. For homes that use propane only for water heating and cooking, 500 gallons stretches to 14-20 months. A propane backup generator at half load uses about 1.5 gal/hr, so 500 gallons sustains roughly 330 hours (~14 days) of continuous backup power.
When should you order more or less than 500 gallons?
Order more (750-1,000 gallons) if your tank capacity allows, you live in a cold climate with 1,200+ annual usage, or you want to lock in a lower per-gallon price. Suppliers typically offer 10-15% off retail at 1,000 gallons. Order less (200-300 gallons) if your tank can't accept 500, you're doing a summer top-off, or you're testing a new supplier before committing to a full fill. Below 200 gallons most suppliers add a partial-fill fee that erases any volume savings.
Why does 500 gallons cost so much more in some states?
Three drivers: feedstock proximity, market structure, and weather. PADD-3 (Texas, Louisiana) is closest to the Mont Belvieu hub and consistently 15-20% below national. PADD-1A (New England) and PADD-5 (West Coast and Hawaii) pay 30-60% premiums on top of higher delivery costs and (especially in NE) winter spot pricing. In single-supplier rural markets the lack of competition adds another 5-10%. The EIA per-state data captures retail averages but not delivery fees or volume discounts, so the realised 500-gallon price varies more than the table suggests.
