Buyers typically pay for propane by the gallon. A 100 lb tank holds roughly 23.5 gallons when full, so the total cost depends mainly on the current price per gallon and any delivery fees. Seasonal demand and regional pricing can also shift totals.
Cost factors include the propane price per gallon, delivery charges, and applicable taxes. The following table summarizes typical ranges and notes.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| Propane (23.5 gal @ price per gallon) | $60 | $85 | $140 | Assumes $2.50–$3.00/gal, plus minor fluctuations |
| Delivery/Service Fee | $0 | $15 | $40 | One-time delivery to home or business |
| Taxes | $0–<$6 | $6–$12 | $15–$25 | Varies by state and locality |
| Contingency | $0 | $5 | $10 | Extra cushion for market spikes |
| Total | $60 | $85–$110 | $180 | Estimated range for a single fill |
Overview Of Costs
Gas price and tank capacity drive the majority of the cost. The tank’s 100 lb rating corresponds to roughly 23.5 gallons of propane. If the price per gallon shifts, the total fill cost moves in lockstep. For budgeting, consider seasonal price volatility and regional supply conditions.

What Drives Price
Price per gallon is the primary driver. Regional supply chains, transportation costs, and local taxes shape totals. Tank size and fill method (automatic vs on-demand) can add or subtract small amounts. Winter usage spikes may lift demand and prices temporarily.
Ways To Save
Shop around within your area for propane suppliers and consider bulk pricing if your facility uses a lot. Some providers offer flat delivery fees or bundled maintenance plans that reduce overall costs over time. Scheduling deliveries during off-peak hours can occasionally yield minor discounts.
Regional Price Differences
Propane pricing shows noticeable regional variation. In the Northeast, delivery charges may be higher but base propane costs can be competitive due to seasonal demand. The Midwest often features moderate delivery fees with steady propane prices. The West Coast can carry higher overall costs due to distribution logistics and local taxes. Expect regional deltas of roughly ±10–30% versus national averages.
