Typical buyers pay $900-$3,500 to buy and install a 100 gallon propane tank, with the biggest cost drivers being tank type, site prep, and local labor rates. This article shows realistic price ranges, per-unit charges, and the variables that change the final cost for a 100 gallon propane tank purchase and installation.
| Item | Low | Average | High | Notes |
|---|---|---|---|---|
| 100 Gal Tank Purchase | $600 | $1,100 | $1,800 | Aboveground vs. ASME vs. DOT variations |
| Installation (labor & site) | $200 | $650 | $1,500 | Excavation, pad, regulator, backfill |
| Initial Fill (propane) | $60 | $120 | $240 | $0.60-$2.40 per gallon depending on market; assumes 30-100 gal |
| Total Installed | $900 | $1,870 | $3,500 | Assumptions: suburban U.S., normal access, standard regulator. |
Typical Total Price to Buy and Install a 100 Gallon Propane Tank
Most homeowners should budget $900-$3,500 total for a 100 gallon propane tank including tank, installation, and first fill.
Typical tank-only pricing is $600-$1,800 depending on ASME (residential, often heavier and more expensive) versus DOT (lighter, sometimes lower-cost) and whether the tank is aboveground or buried. Installation labor and site prep add $200-$1,500. Initial propane fill runs about $0.60-$2.40 per gallon; many installs require 30-100 gallons on the first fill depending on emptiness and local minimum delivery.
Breakdown of Materials, Labor, Equipment, Permits, and Delivery
Breaking the quote into components helps compare contractor bids and spot markups.
| Component | Low | Average | High | Notes |
|---|---|---|---|---|
| Materials (tank, regulator, fittings) | $600 | $1,050 | $1,900 | Tank grade and accessories drive this |
| Labor | $150 | $500 | $1,200 | Typical 1-6 hours |
| Equipment (excavator, crane) | $0 | $150 | $700 | Aboveground may avoid heavy equipment |
| Permits | $25 | $120 | $400 | Local code and inspection fees vary |
| Delivery/Disposal | $50 | $200 | $600 | Delivery fee plus old tank removal if applicable |
How Tank Type and Installation Options Affect Price
Choosing aboveground vs. buried, ASME vs. DOT, and steel thickness changes cost by several hundred dollars.
Aboveground 100 gal tanks are typically $600-$1,200 and install faster with lower equipment costs. Buried tanks add $300-$1,000 for excavation, sand bedding, and corrosion protection. ASME-certified tanks cost $200-$500 more than basic DOT tanks but may be required by some suppliers or codes.
Site Conditions That Increase the Final Quote
Hard access, rocky soil, long gas runs, and steep slopes each add measurable cost.
Examples of threshold impacts: excavation in rocky soil or bedrock typically adds $500-$1,500; run lengths over 50 linear feet for piping add $3-$8 per linear foot plus fittings; lift/crane requirements for tight yards add $300-$900. If a permit triggers a municipality-level inspection, expect $50-$400 extra.
Practical Ways To Lower the Price for a 100 Gallon Tank
Control scope: choose aboveground placement, accept DOT tank where allowed, and prepare the site yourself to save money.
- Opt for aboveground mounting on a simple concrete or gravel pad: saves $300-$1,000 versus burying.
- Get multiple quotes and ask for an itemized bid to compare material and labor separately.
- Schedule installation off-season (spring/fall) to reduce rush fees and improve contractor availability.
- If replacing an old tank, remove it yourself where allowed to avoid disposal fees of $100-$500.
Regional Price Differences Across the U.S.
Expect 10%-25% higher costs in urban Northeast and West Coast markets and 5%-15% lower in rural Midwest and South.
Typical deltas: Northeast/California +10%-25% due to labor and permitting; Mountain West +5%-15% for remote access; Midwest -5%-15% with lower labor rates. Delivery fees for propane contents vary by distance and local propane market cycles.
Installation Time, Labor Crew, and Typical Job Duration
Most 100 gallon tank jobs take 2-8 hours with a 1-3 person crew for standard aboveground installs.
Simple aboveground setups: 2 workers, 2-4 hours ($150-$600 labor). Buried tanks: 2-4 workers, 4-10 hours including excavation and backfill ($400-$1,200 labor). Long gas runs or plumbing to multiple appliances can add hours and increase the labor subtotal accordingly.
Common Add-Ons, Fees, and Real Quote Examples
Watch for common extras: regulator kits $75-$250, protective cages $50-$400, and removal fees $100-$500.
| Example | Specs | Labor Hours | Per-Unit Rates | Total |
|---|---|---|---|---|
| Budget Aboveground | DOT 100 gal, gravel pad, local delivery | 2 | Tank $650, Install $200, Fill $80 | $930 |
| Average Suburban | ASME 100 gal, concrete pad, regulator, 30 ft run | 4 | Tank $1,150, Install $600, Fill $120 | $1,870 |
| Full-Service Buried | ASME buried 100 gal, excavation, crane, removal | 8 | Tank $1,500, Install $1,200, Fill $200 | $3,500 |
Assumptions: prices in USD, typical suburban installations, material-grade tanks, and no major site remediation.
