If your propane tank is empty, you have to refill it. How much does that cost? To address the refill costs, we have designed a calculator that will tell you how much does it cost to fill a propane tank. On top of that, you will also find a chart with propane tank refill costs for 100-gallon, 250-gallon, 500-gallon, and 1,000-gallon propane tanks.
Fully filling a propane tank can cost anywhere from $160 to $6,400.
Why such a big interval? We need to be aware that the cost to fill a propane tank depends on only two factors:
- Size of your propane tank. How much is it to refill a propane tank obviously depends on how big a tank you have. Example: It will be cheaper to fill a 250-gallon tank than to fill a big 1,000-gallon residential propane tank.
- Price of propane per gallon. The higher the propane cost, the more you will have to pay to refill a propane tank. You can check the current propane costs on the EIA website here. We made the calculations on how is it to fill a propane tank if the cost of propane is $2.00/gallon, $2.86/gallon (US national average), $3.00/gallon, and $4,00/gallon and gathered them in the chart below.
Here is a vital thing you need to account for when calculating how much it costs to refill a propane tank:
Propane tanks hold at most 80% of the specified tank size. You never put 1,000 gallons of propane in a 1,000-gallon propane tank; at most, you can fill it with 800 gallons of propane. This is done for safety reasons. If you would fill a propane tank to 100% of its specified capacity, you would risk a high outward pressure on the inner walls of the propane tank at higher temperatures (propane expands at higher temperatures).
Considering all this, here is the step-by-step how to determine the refill cost of any propane tank:
- Multiply propane tank size by 0.8 to adequately determine the amount of propane. This accounts for that 80% filling rule; a 1,000-gallon tank can be refilled with 800 gallons of propane, a 500-gallon tank can be filled with 400 gallons of propane, and so on. Here you will get the amount of propane that goes into your propane tank.
- Multiply the amount of propane by the price of propane per gallon. If you fill 200 gallons of propane in a 250-gallon tank, you just need to check what is the price per gallon of propane in your area. Let’s say that propane costs $2.86/gallon. That means that 200 gallons of propane cost $572.00; this is how much you will pay to refill a 250-gallon propane tank using that price per gallon of propane.
Here is the propane tank refill cost formula:
To help you out with all these calculations, we have designed a Propane Tank Refill Cost Calculator. You just input the size of propane tank you want to fill and the price per gallon of propane, and the calculator will automatically calculate how much it is to refill your propane tank.
Further on, you will also find a calculated chart for refill costs for the smallest 100-gallon and biggest 2,000-gallon propane tanks if the price of propane is between $2.00 and $4.00.
Let’s start with this easy-to-use refill cost calculator, and you can consult the chart further on:
Propane Tank Refill Cost Calculator
Here you can insert any propane tank size from 0 to 2,000 gallons (you can check the most common propane tank sizes here) and any propane price from $1.50 to $4.50. The calculator will automatically calculate how much it is to fill a propane tank.
You can also play around with the numbers and see how the refill cost changes if the price of propane changes.
Here is the calculated chart of how much it would cost to fill different propane tanks at different costs of propane:
How Much To Pay For Propane Tank Refilling? (Chart)
| Propane Tank Size (Gallons): | Refill Cost (At $2.00/Gallon): | Refill Cost (At $2.86/Gallon): | Refill Cost (At $3.00/Gallon): | Refill Cost (At $4.00/Gallon): |
| 100 Gallon | $160.00 | $228.80 | $240.00 | $400.00 |
| 250 Gallon | $400.00 | $572.00 | $600.00 | $800.00 |
| 500 Gallon | $800.00 | $1,144.00 | $1,200.00 | $1,600.00 |
| 750 Gallon | $1,200.00 | $1,716.00 | $1,800.00 | $2,400.00 |
| 1000 Gallon | $1,600.00 | $2,288.00 | $2,400.00 | $3,200.00 |
| 1500 Gallon | $2,400.00 | $3,432.00 | $3,600.00 | $4,800.00 |
| 2000 Gallon | $3,200.00 | $4,576.00 | $4,800.00 | $6,400.00 |
