The cost of a propane tank varies widely depending on the size and type of tank, as well as whether installation is included.

• Small propane tanks for grills, such as a 20-pound tank, typically cost between $35 and $60. Filling these tanks usually costs an additional $7 to $20, making the total cost for a full 20-pound tank around $42 to $80

• Medium-sized tanks, such as a 100-gallon tank suitable for home use, generally cost between $400 and $700 without installation

• Larger residential tanks, like a 250-gallon tank, cost between $500 and $1,000 , while a 500-gallon tank ranges from $700 to $3,000 depending on whether it is above ground or underground

• The average price for a 500-gallon above-ground propane tank is about $1,500 to $1,700 , and installation can add to this cost, with total installation expenses ranging from $600 to $2,500 or more depending on tank size, location, and labor

• Very large tanks (1,000 gallons or more) can cost between $1,500 and $5,500 , with underground installation costing more, sometimes up to $4,500 or higher

• For commercial or agricultural use, tanks can be much larger (2,000 to 30,000 gallons) and cost between $11,000 and $80,000

In summary, small portable tanks cost under $100, mid-sized residential tanks range from a few hundred to a few thousand dollars, and large tanks with installation can cost several thousand dollars or more. Installation and maintenance costs should also be considered in the total expense
