The best price for a propane tank depends on capacity, whether it is aboveground or underground, and whether the quote includes delivery, setup, permits, and fuel. Many U.S. homeowners pay about $800-$3,500 for an aboveground tank installed, while an underground installation commonly runs $3,000-$9,000.
Smaller tanks cost less upfront but may need more frequent refills; local labor, site access, and buying versus leasing also change the total.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 100-120-gallon tank, aboveground | $400 | $700 | $1,000 | Tank purchase only |
| 250-gallon tank, aboveground | $700 | $1,100 | $1,500 | Tank purchase only |
| 500-gallon tank, aboveground | $1,200 | $1,800 | $2,500 | Tank purchase only |
| 500-gallon tank, installed aboveground | $1,500 | $2,600 | $3,500 | Typical residential setup |
| 500-gallon tank, installed underground | $3,000 | $5,000 | $6,500 | Excavation and corrosion protection included |
What propane tanks cost by capacity and placement
For a purchased tank, a typical range is $400-$4,000 depending on capacity, construction, and whether it is designed for underground use. Installed prices rise when the job needs a pad, regulator, gas line, trenching, or inspection. A standard aboveground setup is usually less expensive than burying the tank, which adds excavation, backfill, and protective equipment.
For many homes, an installed aboveground tank lands between $1,500 and $3,500; underground projects often start near $3,000. These are broad planning ranges, not fixed national quotes. Tank availability, installer minimum charges, and local code requirements can shift the price substantially.
| Capacity | Tank-only price | Aboveground installed | Underground installed | Common use |
|---|---|---|---|---|
| 100-120 gallons | $400-$1,000 | $800-$1,800 | $2,500-$4,500 | Cooking, fireplace, limited appliances |
| 250 gallons | $700-$1,500 | $1,200-$2,500 | $3,000-$5,500 | Moderate household demand |
| 500 gallons | $1,200-$2,500 | $1,500-$3,500 | $3,000-$6,500 | Whole-home heating and appliances |
| 1,000 gallons | $2,000-$4,000 | $2,500-$5,000 | $4,500-$9,000 | High demand or larger properties |
Assumptions: Residential-grade tank, standard materials, normal access, and typical U.S. labor; fuel purchases and major gas-line extensions may be extra.
Which tank, delivery, and hookup charges make up the quote
A written estimate should distinguish the tank price from installation and delivery. Some suppliers bundle setup into a lease or fuel agreement, while a tank purchase quote may list each task separately. Ask whether the stated tank capacity is the tank’s water capacity; usable propane volume is lower because tanks are not filled to 100%.
Installation line items can add hundreds or several thousand dollars beyond the tank itself, especially for buried tanks or long gas runs. The ranges below are common residential planning figures; not every job needs every item.
| Quote component | Typical price | What changes the charge | Usually included? |
|---|---|---|---|
| Tank delivery and placement | $100-$500 | Distance, truck access, lifting needs | Sometimes |
| Pad or base for aboveground tank | $100-$400 | Concrete versus prepared gravel, ground condition | Varies |
| Regulator, fittings, and connection | $150-$500 | Tank size, pressure setup, equipment count | Often |
| Gas line installation | $10-$25 per linear ft | Pipe type, route, surface restoration | Usually priced separately |
| Excavation and underground protection | $800-$2,500 | Soil, access, burial depth, tank size | Underground jobs only |
| Permit and inspection | $50-$500 | Municipality, project scope, inspection rules | Varies |
Some estimates also include initial fuel, leak testing, and delivery of the tank. Initial fill is typically billed by the gallon and depends on the local propane rate and the amount delivered. Clarify whether the supplier requires a minimum first fill or charges a service call if the tank is not filled at installation.
How capacity, distance, and burial depth change propane tank pricing
Capacity is a major cost driver, but the right size depends on appliances, heating load, refill access, and expected usage. A home using propane for cooking only may need far less storage than one heating the house, water, and a pool. An installer may review appliance BTU ratings and usage history rather than sizing the tank from square footage alone.
Moving from a 250-gallon to a 500-gallon tank can add roughly $300-$1,000 to tank cost, before site work or line changes. Underground tanks cost more because the vessel must be made and protected for burial, and the installation requires excavation and suitable backfill.
Distance matters too. A gas line over 50 feet can add about $500-$1,250 at common installed rates of $10-$25 per linear foot, though local pricing and surface type vary. Crossing concrete, landscaping, or a driveway can add cutting and restoration charges. A sloped, rocky, wet, or tightly accessible site may need extra labor or machinery.
Tank placement must meet applicable separation distances from buildings, openings, property lines, and ignition sources. Requirements vary by jurisdiction and tank capacity. If a proposed location cannot meet local rules, relocation may require extra pipe, trenching, or a different tank size. For labor estimates, a simple aboveground hookup may take 4-8 hours; a more involved underground job can take 1-3 days.
Aboveground or underground installation for the same capacity
An aboveground tank generally has the lowest installation price and is easier to inspect and service. Its main trade-off is visibility and the need for a stable, code-compliant location. Underground placement keeps the vessel mostly out of sight but adds digging, corrosion protection, and potential landscaping restoration. A 500-gallon aboveground installation commonly totals $1,500-$3,500; the same capacity underground often costs $3,000-$6,500.
Burial commonly adds about $1,500-$3,000 or more over an uncomplicated aboveground setup. The difference can widen when soil is rocky, equipment access is limited, or the excavation route crosses established landscaping. Obtain a site-specific price before choosing based on appearance alone.
Leasing can change the comparison. A supplier may place a tank with little or no upfront tank charge, but the contract can require propane purchases from that company, impose delivery minimums, or charge removal and transfer fees. Buying gives more control over supplier choice, but the owner pays for the tank, installation, inspections, and eventual replacement. Compare the full agreement rather than just the initial charge.
Regional labor rates and delivery access shift U.S. quotes
Prices are often higher in dense metro areas and remote locations for different reasons. Urban areas can have higher labor rates, permit costs, and difficult access. Rural properties may have lower hourly rates but longer delivery distances, fewer competing installers, or extra charges for travel and equipment mobilization.
Compared with a typical local quote, metro projects may run 10%-25% higher, while remote sites can add 10%-30% when travel or access is difficult. These are comparison ranges, not guaranteed regional surcharges. A nearby supplier with an available truck may quote less than a distant company even in a high-cost market.
Climate and seasonal demand also affect scheduling. In colder regions, installers and propane suppliers can be busier before and during the heating season. A non-urgent spring or summer installation may offer more scheduling flexibility, but it does not guarantee a lower price. Weather, excavation conditions, and contractor availability still matter.
For a useful comparison, request at least two or three itemized bids from companies serving the same area. Confirm the quote uses the same tank capacity, aboveground or underground placement, line length, delivery terms, and permit scope. A low quote that omits excavation or regulator work may not be the lowest final price.
Three residential quote examples show the price difference
These examples illustrate how scope changes the total. Each assumes standard residential equipment and excludes the propane itself. Actual bids depend on location, access, soil, and local inspection requirements.
| Project | Scope and labor | Estimated total | Why it costs this much |
|---|---|---|---|
| 120-gallon aboveground | Tank, short connection, pad, 4-6 labor hours | $1,000-$1,700 | Small tank and limited line work |
| 500-gallon aboveground | Tank, regulator, 30-ft line, 6-10 labor hours | $2,000-$3,400 | Whole-home capacity with standard access |
| 500-gallon underground | Burial-rated tank, excavation, 40-ft line, 1-2 workdays | $4,000-$6,500 | Digging, protective measures, and restoration |
In the second example, the gas line alone may account for about $300-$750 at $10-$25 per linear foot. If the route requires concrete cutting or additional permits, the actual quote can exceed the table range. Ask the contractor to separate labor, tank, piping, and site work so a change in scope is easy to identify.
Tank ownership, lease fees, and five-year spending
Buying a tank costs more upfront but may permit shopping among propane suppliers, subject to tank ownership and safety rules. Leasing reduces or removes the initial tank purchase, although the supplier may include annual fees, minimum delivery terms, or a higher per-gallon rate. A leased tank generally remains the supplier’s property, so switching companies may require a tank removal or a new installation.
Compare the purchase price plus installation against five years of lease charges and any difference in fuel pricing. For example, a $2,600 installed tank purchase has a higher first-year cost than a no-upfront-cost lease, but the lease could become more expensive if it adds recurring fees or restricts competitive fuel quotes.
Ask who pays for inspection, regulator replacement, corrosion checks, and repairs. A tank’s service life depends on type, maintenance, installation, and local conditions; underground tanks need appropriate corrosion protection and monitoring. Warranty coverage may apply to the vessel but exclude labor, excavation, or damage caused by site conditions. Get the warranty term and exclusions in writing.
How to lower the installed price without cutting safety
Choose capacity based on the actual appliance load and refill schedule rather than automatically selecting the largest tank. Oversizing can raise tank and installation costs without providing useful savings. Conversely, undersizing a tank used for high-demand heating may cause inconvenient refills and can affect vaporization performance in cold weather. Ask the installer to explain the recommended size.
The most dependable savings come from controlling scope and comparing equivalent, itemized bids. If an aboveground tank meets the property’s layout and local requirements, it is usually less expensive than burial. Keep the line route direct where practical, clear the installation area before delivery, and confirm whether a suitable existing pad or trench can be used safely and legally.
Schedule non-urgent work before peak heating demand when possible, and ask whether delivery and installation can be combined to avoid a separate trip charge. Do not skip required permits, inspections, pressure testing, or code-compliant clearance distances. A cheaper quote that leaves out safety-critical work can lead to added charges or an unsafe installation.
When comparing suppliers, check the tank ownership terms, fuel price, minimum delivery, rental fee, and early termination conditions alongside installation. If an existing tank is serviceable, request an inspection and repair quote before replacing it. Replacement may still be necessary for corrosion, damage, leaks, or code issues, but a professional assessment can distinguish required work from optional upgrades.
Before accepting a quote, confirm the tank size and type, delivery, pad or excavation, regulator, line footage, permits, inspection, initial fill, and disposal of any old equipment. Request written prices for uncertain site work and ask how added labor is billed. This makes the quoted total easier to compare and reduces the chance of an unexpected bill.
