Best Time to Buy Propane: Seasonal Pricing Guide (2026)
Propane prices are 20-30% cheaper in summer than winter. Here is how to time your purchase to save hundreds of dollars per year.
Month-by-Month Typical Propane Prices (National Average)
Based on EIA historical residential propane price patterns. Actual prices vary by state and year. Summer prices reflect typical 5-year average troughs; winter prices reflect typical peaks.
The Summer Fill Strategy: Step by Step
Contact your supplier in early May, before summer grilling season drives up demand at refill stations. Ask for their summer pricing and whether they offer a summer pre-buy contract.
Request a full fill (to the 80% capacity limit). Do not do a partial fill - you want maximum propane at the summer low price. A full 500-gallon tank will be filled to approximately 400 gallons.
Some suppliers will lock in the summer price for fill-ups through September or October. This lets you top off in fall at summer prices even as wholesale prices start rising.
Even with a full summer fill, cold-climate homes will likely need additional deliveries in winter. Budget for 1 to 2 smaller winter fills at higher prices. The summer fill just reduces how much you buy at peak pricing.
Propane Contract Types: Which Is Right for You?
Lock in a set per-gallon price for the entire heating season. Protects against price spikes but you miss out if prices fall. Best signed in summer.
- Predictable budget
- Protection from spikes
- Peace of mind
- Miss summer discounts if signed in fall
- Often require large minimum volume
Price cannot go above the cap, but can drop below it if the market falls. The best of both worlds - but costs a premium over market rate.
- Downside protection
- Benefit if prices fall
- Popular option
- Typically $0.10-$0.25/gal premium over market
- Cap fee paid upfront
You pay whatever the supplier's price is at time of delivery. Most common arrangement. Maximum flexibility, maximum price risk.
- No commitment
- Benefit fully from price drops
- Most flexible
- Full exposure to price spikes
- Budget unpredictability in winter
Pay a fixed monthly amount year-round regardless of usage. Supplier sets amount based on prior year consumption. Simplifies budgeting.
- Predictable monthly payment
- Easy to budget
- Supplier-managed
- May overpay if usage falls
- Settlement payment at year end if usage is higher
Propane Price Forecast: Winter 2026-27
EIA projects stable to slightly declining retail propane prices for winter 2026-27. Wholesale propane prices averaged approximately $0.74/gal in early 2026, about $0.10 below the prior winter. Strong domestic production from the Permian Basin and continued expansion of US LPG export capacity have created favorable supply conditions.
Key risk factors to watch: A colder-than-normal winter (La Nina weather pattern), Hurricane season disruptions to Gulf Coast production, or a significant increase in LNG/LPG exports could push prices meaningfully higher. The base case is stable pricing, but the upside risk is greater than the downside risk heading into 2026-27.
Our recommendation: Fill in summer 2026 at the expected trough of $2.35 to $2.55/gal nationally. If your supplier offers a fixed price contract in the $2.65 to $2.80 range for winter delivery, that is worth considering for risk-averse households.
