Filling a 20 lb LP (liquid propane) tank is a common task for many homeowners who use propane for grilling, heating, or other household applications. The cost to fill these tanks can vary significantly depending on several factors, including your location, the current market price of propane, and whether you’re refilling or exchanging your tank. Understanding these costs can help you budget effectively and potentially save money on your propane needs.
On average, the cost to fill a 20 lb propane tank ranges from $14 to $20 for a refill. However, prices can fluctuate based on market conditions and your specific location. It’s important to note that a 20 lb tank actually holds about 4.7 gallons of propane when filled to its 80% capacity limit, which is mandated for safety reasons.
| Service Type | Average Cost Range |
|---|---|
| Refill | $14 – $20 |
| Exchange | $20 – $30 |
Factors Affecting Propane Tank Refill Costs
Several key factors influence the cost of filling your 20 lb propane tank. Understanding these can help you make informed decisions about when and where to refill your tank:
1. Current Propane Market Price: The wholesale price of propane fluctuates based on supply and demand, much like gasoline prices. This directly impacts the retail price you’ll pay for a refill.
2. Location: Propane prices can vary significantly from one region to another due to differences in supply, transportation costs, and local competition. Urban areas often have lower prices due to higher competition and easier access to supply.
3. Seasonality: Propane prices tend to be higher during peak demand seasons, typically in winter when heating needs increase. Summer can also see price spikes due to increased use for grilling.
4. Refill vs. Exchange: Generally, refilling your existing tank is cheaper than exchanging it for a pre-filled one. However, exchanges can be more convenient and are often available at more locations.
5. Retailer: Prices can vary between different propane suppliers. Some retailers may offer lower prices to attract customers, while others might charge a premium for convenience or additional services.
6. Volume Discounts: Some suppliers offer discounts for filling multiple tanks or larger tanks, which can reduce your per-gallon cost.
7. Membership Programs: Certain retailers, like Costco, offer discounted propane refills to their members, which can lead to significant savings over time.
Comparing Refill and Exchange Options
When it comes to getting propane for your 20 lb tank, you generally have two options: refilling your existing tank or exchanging it for a pre-filled one. Each method has its pros and cons:
Refilling Your Tank
Refilling involves taking your empty or partially empty tank to a propane supplier who will fill it to its proper capacity. This method typically offers several advantages:
- Cost-Effective: Refilling is usually 15-20% cheaper than exchanging, as you’re only paying for the propane itself.
- Full Capacity: You get a full 4.7 gallons of propane, unlike some exchange programs that may not fill tanks completely.
- Environmental Benefits: Reusing your tank reduces waste and the energy required to recycle and redistribute tanks.
However, refilling may not be as convenient, as fewer locations offer this service compared to exchange programs.
Exchanging Your Tank
Tank exchange programs allow you to swap your empty tank for a pre-filled one. While often more expensive, this option offers some benefits:
- Convenience: Exchange locations are more common, including many gas stations and retail stores.
- Time-Saving: The exchange process is usually quicker than waiting for a refill.
- Tank Maintenance: You receive a different tank each time, which is inspected and maintained by the exchange company.
The downside is that exchanged tanks may not be filled to their full 4.7-gallon capacity, sometimes containing only 15-18 pounds of propane instead of the full 20 pounds.
Tips for Saving Money on Propane Tank Refills
To maximize your savings when filling your 20 lb propane tank, consider the following strategies:
1. Shop Around: Prices can vary significantly between suppliers. Check prices at different locations before refilling.
2. Refill Instead of Exchange: Whenever possible, opt for refilling your tank rather than exchanging it to get more propane for your money.
3. Buy in Off-Season: Try to refill your tanks during off-peak seasons when demand and prices are lower.
4. Join Membership Programs: If you frequently use propane, consider joining a membership program that offers discounted refills.
5. Use Apps and Websites: Utilize propane price comparison apps or websites to find the best deals in your area.
6. Maintain Your Tank: Proper maintenance can extend the life of your tank and ensure it passes inspection for refills.
7. Consider Larger Tanks: If you use a lot of propane, investing in a larger tank can lead to lower per-gallon costs and fewer refills.
Understanding Propane Pricing and Measurements
To better understand the cost of filling your 20 lb propane tank, it’s helpful to know how propane is priced and measured:
- Propane is sold by the gallon, but tanks are often referred to by their pound capacity.
- A 20 lb tank holds 4.7 gallons of propane when filled to its 80% capacity.
- One gallon of propane weighs approximately 4.2 pounds.
- Propane prices are typically quoted per gallon, so you’ll need to multiply the per-gallon price by 4.7 to get your total fill cost.
It’s also important to note that propane prices can fluctuate daily, much like gasoline prices. This is why it’s beneficial to check current prices before refilling.
