Average Cost to Fill a Propane Tank: Comprehensive Guide for Homeowners
Filling a propane tank is an essential task for many households, especially those relying on propane for heating, cooking, or grilling. The average cost to fill a propane tank varies widely depending on tank size, location, propane prices, and the provider. This guide provides detailed insights into the various factors affecting propane filling costs and helps homeowners understand what to expect when refilling their tanks.
| Type of Tank | Average Capacity (gallons) | Average Cost to Fill | Typical Uses |
|---|---|---|---|
| Small Portable Tanks | 5 to 20 | $15 – $50 | Grills, small heaters, RVs |
| Standard Home Tanks | 100 to 500 | $80 – $400 | Home heating, water heaters, cooking |
| Large Commercial Tanks | 500+ | $400 and Up | Commercial heating, agriculture, fleet vehicles |
Factors Influencing the Cost to Fill a Propane Tank
Several factors contribute to the variation in propane refill costs.
1. Tank Size and Capacity
The larger the tank, the more propane it can hold, which increases the total refill cost. Propane tanks are measured in gallons, with common residential sizes ranging from 100 to 500 gallons. A 20-pound portable grill tank, for example, typically holds about 4.7 gallons and costs much less to fill than a large 500-gallon home tank.
2. Propane Price Per Gallon
Propane pricing fluctuates based on supply and demand, seasonality, and geographic location. On average in the U.S., propane costs range from $2.00 to $3.50 per gallon. Prices tend to rise in colder months due to increased demand for heating.
3. Location and Delivery Charges
Filling costs can vary regionally due to transportation costs, local regulations, and the proximity of suppliers. Remote or rural areas may incur additional delivery fees. Some suppliers charge a flat delivery fee or offer free refill with minimum purchase amounts.
4. Service Provider and Contract Type
Costs may differ between companies depending on their pricing strategy and whether customers are on contract plans or pay-per-fill. Contract customers might get discounted propane prices but have minimum purchase commitments.

| Tank Type | Average Tank Size | Typical Propane Price Per Gallon | Approximate Fill Cost | Notes |
|---|---|---|---|---|
| Portable Grill Tank | 5 to 20 lbs (1.2 to 4.7 gallons) | $3.00 – $4.50 | $15 – $40 | Common for outdoor grills and small heaters |
| 100-Gallon Residential Tank | 100 gallons | $2.50 – $3.00 | $250 – $300 | Suitable for small households |
| 250-Gallon Residential Tank | 250 gallons | $2.10 – $2.80 | $525 – $700 | Average size for medium homes |
| 500-Gallon Residential Tank | 500 gallons | $2.00 – $2.50 | $1,000 – $1,250 | Common for large homes or properties |
How to Calculate the Cost to Fill Your Propane Tank
To estimate your fill cost accurately, follow these steps:
- Know Your Tank Size: Identify your tank’s gallon capacity.
- Determine the Amount Needed: Check your tank gauge to find how many gallons are needed to fill it.
- Check Local Propane Rates: Find the current per-gallon propane price in your area.
- Include Delivery Fees: Add any fixed delivery or service fees charged by your supplier.
For example, filling a 250-gallon tank that is half empty (125 gallons) at $2.50 per gallon, plus a $30 delivery fee, costs:
(125 gallons x $2.50) + $30 = $312.50 + $30 = $342.50
Seasonal Variations in Propane Costs
Propane prices often increase during winter because of higher heating demand. It is common to see prices 10-20% higher in colder months. Conversely, summer months tend to offer lower rates. Locking in prices through propane service contracts before the heating season can provide cost savings.
Additional Costs to Consider When Filling a Propane Tank
- Tank Rental Fees: Many homeowners rent tanks instead of owning them, which can add monthly fees.
- Tank Inspection and Maintenance: Safety inspections or repairs might be required periodically, affecting overall costs.
- Emergency Fill or Rush Delivery: Some companies charge extra for after-hours or expedited delivery services.
Comparing Propane Filling vs. Exchange Services
Some users opt for propane tank exchange for convenience. Exchange tanks differ in cost and size, and can be more expensive per gallon but quicker to obtain.
| Service Type | Cost Per Gallon | Convenience | Typical Use |
|---|---|---|---|
| Refill at Station or Delivery | $2.00 – $3.50 | Lower cost, wait time varies | Home tanks, bulk users |
| Tank Exchange | $3.50 – $5.00 | Fast swap, limited availability | Portable grill tanks, RV users |
Tips to Lower Propane Filling Costs
- Buy in Bulk: Larger fills usually have a lower cost per gallon.
- Compare Providers: Shop around local suppliers and consider online price trackers.
- Schedule Off-Season Fills: Purchase propane in the spring or summer for better rates.
- Maintain Tank Equipment: Proper maintenance helps avoid leaks and ensures efficient propane use.
