1,000-Gallon Propane Tank Refill Cost: $2,139 in 2026
A 1,000-gallon home propane tank holds 800 usable gallons after the 80% safety fill. At the latest EIA national residential average ($2.67/gal), a full refill from near-empty costs about $2,139 at retail. 1000-gallon tanks are typical in cold climates (New England, upper Midwest, Mountain) where annual usage exceeds 1,000 gallons, or for homes that combine whole-home heating with a propane backup generator. A 1000-gallon tank often supports the full heating season on a single fill.

1,000-Gallon Refill: How the Cost Breaks Down
- Start with the EIA per-gallon average. The current US residential propane price is $2.67/gal (week ending 30 March 2026). State-by-state, the spread is $1.64 (cheapest, Nebraska) to $4.71 (most expensive, Florida). Your local supplier sets a retail rate near your state's EIA average.
- Multiply by usable gallons. 1,000 nominal × 0.80 safety fill = 800 usable gallons. 800 × $2.67 = $2,139 at the national-average retail rate.
- Subtract the volume discount. At a 1,000-gallon delivery size, most suppliers take 10-15% off the per-gallon rate. At 1000 gallons you're at the best residential per-gallon pricing tier. Most suppliers take 10-15% off retail and many will negotiate further for repeat-customer auto-delivery accounts.
- Add delivery fee (if any). Many suppliers include delivery free at this order size. Some charge a flat $0-$50 per stop, or waive it on auto-delivery accounts.
- Skip the partial-fill surcharge. Most suppliers add $25-$75 on deliveries below 200 gallons. At 1,000 gallons you're well above the threshold, so this surcharge does not apply.
Auto-Delivery vs Will-Call for 1,000-Gallon Tanks
Supplier monitors degree-days (or a smart tank gauge) and schedules fills automatically. Typically 5-10% cheaper per gallon because the supplier optimises route density. Default for 1,000-gallon residential customers.
You call when the gauge reads 20-30%. Useful if you have your own tank gauge alert OR you want price flexibility (calling at a forecast low). Pays the higher spot rate; only worth it if you watch pricing actively.
Lock a per-gallon rate in summer (typically May-Aug) for the next winter's deliveries. Usually 5-10% under spot, with a cap-price option that lets you keep the savings if the market falls. Strongly worth it in EIA-forecast spike years.
